Dermal autografts may offer a safer and more cost-effective alternative. The purpose of this prospective study was to compare the outcomes of tissue expander breast reconstruction using dermal autografts with ADM-assisted reconstruction. Patients undergoing tissue expander breast reconstruction with either ADM or dermal autografts were enrolled. Autografts were harvested from the lower abdomen. At each follow-up visit, patients were surveyed on a seven-point scale for scar and overall satisfaction. Biopsies taken at the time of device exchange were evaluated histologically with CD34 staining to assess tissue integration and vessel ingrowth. Expansion parameters, complications, procedural costs, and operative times were compared. Forty-eight patients were enrolled (76 breasts). Twenty-seven patients received ADM, and twenty-one patients received dermal autograft. Wound healing complications were significantly higher in the ADM group (14.8% versus 4.8%, p-value = 0.03), as were major complications (18.5% versus 0%, p-value < 0.01). Histologic vessel counts in the autograft group averaged 21 vessels/mm(2), compared to 7 vessels/mm(2) in the ADM group (p-value < 0.01). There was no difference between the two groups in scar satisfaction or overall satisfaction. Patients receiving dermal autograft had a lower incidence of major complications and delayed wound healing than patients who received ADM. Despite harvest time, the overall cost of the ADM-assisted expander placement was higher. Dermal autograft-assisted breast reconstruction offers many of the benefits of ADM, but with a lower cost and improved safety profile.

Eligible women were older than 18 years with breast carcinoma or a gene mutation linked with breast cancer who intended to undergo skin-sparing mastectomy and immediate IBBR. Randomisation was done electronically, stratified per centre and in blocks of ten to achieve roughly balanced groups. Women were assigned to undergo one-stage IBBR with ADM (Strattice, LifeCell, Branchburg, NJ, USA) or two-stage IBBR. The primary endpoint was quality of life and safety was assessed by the occurrence of adverse outcomes. Analyses were done per protocol with logistic regression and generalised estimating equations. This study is registered at Nederlands Trial Register, number NTR5446.FINDINGS: 142 women were enrolled between April 14, 2013, and May 29, 2015, of whom 59 (91 breasts) in the one-stage IBBR with ADM group and 62 (92 breasts) in the two-stage IBBR group were included in analyses. One-stage IBBR with ADM was associated with significantly higher risk per breast of surgical complications (crude odds ratio 3·81, 95% CI 2·67-5·43, p<0·001), reoperation (3·38, 2·10-5·45, p<0·001), and removal of implant, ADM, or both (8·80, 8·24-9·40, p<0·001) than two-stage IBBR. Severe (grade 3) adverse events occurred in 26 (29%) of 91 breasts in the one-stage IBBR with ADM group and in five (5%) of 92 in the two-stage IBBR group. The frequency of mild to moderate adverse events was similar in the two groups.INTERPRETATION: Immediate one-stage IBBR with ADM was associated with adverse events and should be considered very carefully. Understanding of selection of patients, risk factors, and surgical and postsurgical procedures needs to be improved.FUNDING: Pink Ribbon, Nuts-Ohra, and LifeCell.BACKGROUND: The evidence justifying the use of acellular dermal matrices (ADMs) in implant-based breast reconstruction (IBBR) is limited. We did a prospective randomised trial to compare the safety of IBBR with an ADM immediately after mastectomy with that of two-stage IBBR.

The impact of obesity, radiation, and chemotherapy on complications and biointegration of matrix was investigated. The trial was divided into three stages, with stage I results reported here.RESULTSOne hundred twenty-eight patients (199 breasts) were randomized equally over 2.5 years. Most patients were white, healthy nonsmokers. The overall complication rate was 36.2 percent; half of the complications were minor. The AlloDerm and DermaMatrix groups had similar rates of complications (33.6 percent versus 38.8 percent; p = 0.52), consisting mostly of skin necrosis (17.8 percent versus 21.4 percent; p = 0.66) and infections (13.9 percent versus 16.3 percent; p = 0.29), both of which led to tissue expander losses (5 percent versus 11.2 percent; p = 0.11). The AlloDerm group required less time for completion of expansion (42 days versus 70 days; p < 0.001). Obesity was associated with poor matrix biointegration and a longer drain time, both of which were associated with higher complication rates.CONCLUSIONThe Breast Reconstruction Evaluation Using Acellular Dermal Matrix as a Sling Trial is the largest randomized trial to date in matrix breast reconstruction and emphasizes the importance of careful patient and allograft selection to minimize complications.CLINICAL QUESTION/LEVEL OF EVIDENCETherapeutic, II.BACKGROUNDUse of acellular dermal matrix in tissue expander breast reconstruction has become a popular adjunct to the total submuscular technique. The question remains as to which matrix, if any, is ideal for breast reconstruction.

The source population will be members of the mastectomy cohort with stage T0 to TII disease, proficient in English, over the age of 18 years, and planning to undergo SSM or NSM with immediate implant breast reconstruction. Stratified randomization will maintain a balanced distribution of important prognostic factors (study site and unilateral versus bilateral procedures). The primary outcome is patient satisfaction and QOL as measured by the validated and procedure-specific BREAST-Q. Secondary outcomes include short- and long-term complications, long-term aesthetic outcomes using five standardized photographs graded by three independent blinded observers, and a cost effectiveness analysis.DISCUSSION: There is tremendous interest in using ADM in implant breast reconstruction, particularly in the setting of one-stage direct to implant reconstruction where it was previously not possible without the intermediary use of a temporary tissue expander (TE). This unique advantage has led many patients and surgeons alike to believe that one-stage ADM-assisted implant reconstruction should be the procedure of choice and should be offered to patients as the first-line treatment. We argue that it is crucial that this technique be scientifically evaluated in terms of patient selection, surgical technique, complications, aesthetic outcomes, cost-effectiveness, and most importantly patient-reported outcomes before it is promoted as the new gold standard in implant-based breast reconstruction.TRIAL REGISTRATION: ClinicalTrials.gov: NCT00956384.BACKGROUND: The two-stage tissue expander/implant (TE/I) reconstruction is currently the gold standard method of implant-based immediate breast reconstruction in North America. Recently, however, there have been numerous case series describing the use of one-stage direct to implant reconstruction with the aid of acellular dermal matrix (ADM). In order to rigorously investigate the novel application of ADM in one-stage implant reconstruction, we are currently conducting a multicentre randomized controlled trial (RCT) designed to evaluate the impact on patient satisfaction and quality of life (QOL) compared to the two-stage TE/I technique.

The impact of body mass index, smoking, diabetes, mastectomy type, radiation therapy, and chemotherapy on outcomes was analyzed. Acellular dermal matrix biointegration was analyzed clinically and histologically. Patient satisfaction was assessed by means of preoperative and postoperative surveys. Logistic regression models were used to identify predictors of complications.RESULTSThis article reports on the study design, surgical technique, patient characteristics, and preoperative survey results, with outcomes data in a separate report. After 2.5 years, we successfully enrolled and randomized 128 patients (199 breasts). The majority of patients were healthy nonsmokers, with 41 percent of patients receiving radiation therapy and 49 percent receiving chemotherapy. Half of the mastectomies were prophylactic, with nipple-sparing mastectomy common in both cancer and prophylactic cases. Preoperative survey results indicate that patients were satisfied with their premastectomy breast reconstruction education.CONCLUSIONResults from the Breast Reconstruction Evaluation Using Acellular Dermal Matrix as a Sling Trial will assist plastic surgeons in making evidence-based decisions regarding acellular dermal matrix-assisted tissue expander breast reconstruction.CLINICAL QUESTION/LEVEL OF EVIDENCETherapeutic, II.BACKGROUNDRecent literature has focused on the advantages and disadvantages of using acellular dermal matrix in breast reconstruction. Many of the reported data are from low level-of-evidence studies, leaving many questions incompletely answered. The present randomized trial provides high-level data on the incidence and severity of complications in acellular dermal matrix breast reconstruction between two commonly used types of acellular dermal matrix.

Tissue expander-based breast reconstruction has been plagued with pain and discomfort. Objective: The purpose of this pilot study was to evaluate the role of a neurotoxin (Botulinum toxin A) in expander-based breast reconstruction. Methods: Thirty patients underwent mastectomies with immediate expander or acellular dermal matrix reconstruction. The neurotoxin group (n = 15) received 40 units of neurotoxin (Botulinum toxin A, Allergan, Inc, Irvine, CA) into each pectoralis major muscle through 4 serial injections and the placebo group (n = 15) received 4 serial injections of 0.9% NaCl. All patients were followed over 1 year, and patient demographics, VAS (visual analog score), laterality, office visits, amount of expansion and number of times to full expansion, and amount of narcotics required were recorded. Statistical significance was considered as p < .05. Results: There were no significant differences between the two groups in terms of age, laterality, expander size, or complications (p = .46-.66). There was a significant difference between the two groups in the VAS score, demonstrating decreased pain in the neurotoxin group (p < .05). In addition, there was a significant increase in the volume of expansion per visit in the neurotoxin group as compared to the placebo group (p < .05). There was no significant difference in narcotic use in the first 3 days after surgery; however, there was a significant decrease in use of narcotics from 7 to 45 days in the neurotoxin group (p < .05). There were no complications associated with the use of the neurotoxin. Conclusions: The infiltration of the pectoralis major muscle with neurotoxin in immediate, expander-based reconstruction may be beneficial in reducing pain and expediting expansions.

We conducted a systematic review of studies reporting on the outcomes of ADMs currently used for immediate implant-based breast reconstruction. Methods: Ovid SP versions of EMBASE and MEDLINE databases were used. Search terms were: (("breast" OR "breast reconstruction") AND ("acellular dermal matrix" OR "acellular dermis" OR Strattice OR Surgimend OR Alloderm OR Human acellular dermis OR cadaveric dermis or acellular dermis-assisted or Dermamatrix or FlexHD or Neoform)). Strict inclusion and exclusion criteria were applied, data was abstracted using a pro forma and risk of bias was assessed using the Down's and Black checklist. Results: A total of 27 studies met inclusion criteria. 18/27 were retrospective case series and 9/27 were cohort studies with a non-ADM control group. There were no randomised controlled trials. There were 2 studies on bovine ADM use and 6 on porcine ADM use, with the remainder reporting on human ADMs. Significant risk of bias was demonstrated in the cohort studies, mainly as a result of allocation bias and a lack of information related to the distribution of potential confounders. Conclusions: There remains very little high quality evidence for the outcomes of breast reconstruction using an ADM, particularly for non-human ADMs. High risk of bias means individual study results cannot reliably be combined in the form of a meta-analysis.

Immediately following mastectomy, all patients were randomized to one of two treatment arms: (1) acellular dermal matrix-assisted, tissue expander/implant reconstruction; and (2) submuscular tissue expander/implant placement. All patients were blinded to their treatment arm.RESULTS: One hundred eight consented to participate; 38 were excluded prior to randomization. In total, 70 patients were randomized. There were no differences seen in immediate postoperative pain (p = 0.19) or pain during the expansion phase (p = 0.65) between treatment arms. There was similarly no difference in postoperative narcotic use (p = 0.38). The rate of postoperative expansion did not differ between groups (p = 0.83).CONCLUSIONS: The results suggest that the use of acellular dermal matrix in the setting of tissue expander/implant reconstruction neither reduces postoperative pain nor accelerates the rate of postoperative expansion. An examination of its efficacy in improving long-term outcomes following tissue expander/implant reconstruction is warranted.BACKGROUND: Current efficacy data supporting the routine use of acellular dermal matrices in postmastectomy tissue expander/implant reconstruction are limited. A multicenter, blinded, randomized controlled study was designed to evaluate the effectiveness of acellular dermal matrix in the setting of tissue expander/implant reconstruction. The primary objective of the study was to determine whether the use of matrix would decrease patient-reported postoperative pain. The secondary objective was to determine whether its use would accelerate the rate of postoperative expansion.

Methods This prospective, randomized, controlled, multicenter pilot study was performed at four Austrian breast cancer centers. Fifty patients with oncologic or prophylactic indication for mastectomy and IBBR were randomized to immediate IBBR with either an ADM (Protexa) or a titanized mesh (TiLOOP Bra). Complications, failed reconstruction, cosmetic outcome, patients' quality of life and the thickness of the overlying tissue were recorded immediately postoperatively and 3 and 6 months after surgery. Results 48 patients participated in the study (Protexa group: 23; TiLOOP Bra group: 25 patients). The overall complication rate was 31.25% with similar rates in both groups (Protexa group: 9 versus TiLOOP Bra group: 6; p = 0.188). There was a higher incidence of severe complications leading to failed reconstructions with implant loss in the Protexa group than in the TiLOOP Bra group (7 versus 2; p < 0.0001). An inverted T-incision technique led to significantly more complications and reconstructive failure with Protexa (p = 0.037, p = 0.012, respectively). There were no significant differences in patients' satisfaction with cosmetic results (p = 0.632), but surgeons and external specialists graded significantly better outcomes with TiLOOP Bra (p = 0.034, p = 0.032). Conclusion This pilot study showed use of TiLOOP Bra or Protexa in IBBR is feasible leading to good cosmetic outcomes and high patient satisfaction. To validate the higher failure rates in the Protexa group, data from a larger trial are required.

During implant exchange, intraoperative biopsy specimens were obtained of (1) biointegrated acellular cadaveric dermis and (2) native subpectoral capsule (internal control). Histopathologic analysis was performed. Masked biopsy specimens were scored semiquantitatively by an experienced histopathologist to reflect observed granulation tissue formation, vessel proliferation, chronic inflammatory changes, capsule fibrosis, fibroblast cellularity, and foreign body giant cell inflammatory reaction. Scores were analyzed statistically using the Wilcoxon signed rank test.RESULTSAcellular cadaveric dermis (AlloDerm) had statistically diminished levels for all parameters compared with corresponding native breast capsules (p<0.001).CONCLUSIONSThis represents the first detailed histopathologic comparative analysis between biointegrated acellular cadaveric dermis and native capsules in implant-based breast reconstruction. These histopathologic findings suggest that certain properties intrinsic to acellular cadaveric dermis may limit capsule formation by diminishing inflammatory changes that initiate capsule formation. Further investigation is needed to determine whether acellular cadaveric dermis reduces the incidence of breast capsular contracture.BACKGROUNDAcellular cadaveric dermis in implant-based breast reconstruction provides an alternative to total submuscular placement. To date, there has been no detailed in vivo human analysis of the histopathologic sequelae of acellular cadaveric dermis in implant-based breast reconstruction. Based on clinical observations, we hypothesize that acellular cadaveric dermis decreases the inflammatory response and foreign body reaction normally seen around breast implants.

The primary endpoints were identification of patient-related and surgical factors that were predictive for an adverse outcome and the development of recommendations for patients eligible for implant-based breast reconstruction using the mesh. Complications were divided into major (need for additional surgery), minor (conservative treatment), and implant loss. Univariate and multivariate logistic regression analyses were performed to determine the influence of the patient- and procedure-related characteristics on postoperative complications and implant loss.RESULTSNo risk factors were observed for patient-associated complications. Major complications occurred in 13.4 percent, minor complications in 15.6 percent, and implant loss in 8.7 percent of patients. Univariate analysis revealed procedure-related risk factors for postoperative complications with a bilateral procedure (p = 0.013) or skin expansion before implant surgery (p = 0.043). Multivariate analysis confirmed these risk factors and revealed an increased risk for implant loss in patients with skin necrosis (p < 0.001) and capsule fibrosis (p < 0.001).CONCLUSIONSThis titanium-coated polypropylene mesh shows acceptable complication rates and can be a helpful device in implant-based breast reconstruction. The mesh should only be used in primary cases and, when adhering to the proposed indications, is a safe and convenient option in implant-based breast reconstruction.CLINICAL QUESTION/LEVEL OF EVIDENCERisk, III.BACKGROUNDAn alternative to implant-based breast reconstruction using acellular dermal matrix is the use of a titanium-coated polypropylene mesh. The mesh was approved for implant-based breast reconstruction in Europe in 2008, but only limited clinical data are available.

Since HADM has been shown to stretch following placement in other surgical settings, we hypothesised that stretching would occur in breast reconstruction as well. The goal of the study was to quantify the in situ stretch properties of HADM over time in patients undergoing this procedure. Methods This was an open-label, prospective case series in adult women who underwent post-mastectomy tissue expander/implant breast reconstruction using HADM. HADM construct size was determined at postoperative day 1 and month 3 via ultrasound tracking of metallic 3-mm vessel clips embedded in the graft. Dimensional changes were further examined in four equally sized segments (medial, lateral and two central) of the matrix. Patient satisfaction was evaluated at month 3 (a modified version of the Breast QTM patient questionnaire) and compared with satisfaction reported by a non-HADM reconstruction cohort. Results A total of 31 patients underwent breast reconstruction with HADM. Mean (standard deviation) perimeter increased from 38 (6) cm on postoperative day 1-42 (7) cm at month 3 (+11%; P = 0.002). Surface area increased from 73 (22) to 88 (28) cm2 (+21%; range, 4-35%; P = 0.002). The greatest expansion occurred in the HADM medial and lateral segments (range, 18-30% across the four segments). Patient satisfaction was comparable with that of non-HADM patients. Complications in the HADM group included late seroma, red breast syndrome and urinary tract infection. Complications in the non-HADM cohort included cellulitis, expander explantation, delayed wound healing and skin necrosis. Conclusions During short-term follow-up, HADM exhibited a modest degree of stretching during tissue expander/implant breast reconstruction and was associated with few complications and a high level of patient satisfaction. © 2013 Published by Elsevier Ltd on behalf of British Association of Plastic, Reconstructive and Surgeon.

Recently, however, there have been numerous case series describing the use of one-stage direct to implant reconstruction with the aid of acellular dermal matrix (ADM). In order to rigorously investigate the novel application of ADM in one-stage implant reconstruction, we are currently conducting a multicentre randomized controlled trial (RCT) designed to evaluate the impact on patient satisfaction and quality of life (QOL) compared to the two-stage TE/I technique.Methods/designs: The MCCAT study is a multicenter Canadian ADM trial designed as a two-arm parallel superiority trial that will compare ADM-facilitated one-stage implant reconstruction compared to two-stage TE/I reconstruction following skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM) at 2 weeks, 6 months, and 12 months. The source population will be members of the mastectomy cohort with stage T0 to TII disease, proficient in English, over the age of 18 years, and planning to undergo SSM or NSM with immediate implant breast reconstruction. Stratified randomization will maintain a balanced distribution of important prognostic factors (study site and unilateral versus bilateral procedures). The primary outcome is patient satisfaction and QOL as measured by the validated and procedure-specific BREAST-Q. Secondary outcomes include short- and long-term complications, long-term aesthetic outcomes using five standardized photographs graded by three independent blinded observers, and a cost effectiveness analysis.Discussion: There is tremendous interest in using ADM in implant breast reconstruction, particularly in the setting of one-stage direct to implant reconstruction where it was previously not possible without the intermediary use of a temporary tissue expander (TE). This unique advantage has led many patients and surgeons alike to believe that one-stage ADM-assisted implant reconstruction should be the procedure of choice and should be offered to patients as the first-line treatment. We argue that it is crucial that this technique be scientifically evaluated in terms of patient selection, surgical technique, complications, aesthetic outcomes, cost-effectiveness, and most importantly patient-reported outcomes before it is promoted as the new gold standard in implant-based breast reconstruction.Trial registration: ClinicalTrials.gov: NCT00956384. © 2013 Zhong et al.; licensee BioMed Central Ltd.

The aim of this prospective randomized trial was to compare the outcomes of direct IBBR augmented with an ADM (StratticeTM, LifeCell Cooperation) with those of two-stage IBBR. We report on the first results on the safety outcomes of the two procedures. Material and Methods: A non-blinded randomized controlled trial was conducted at eight hospitals in the Netherlands. Patients who intended to undergo skin-sparing mastectomy and immediate IBBR were randomized to one of two procedures for IBBR: one-stage ADM-assisted IBBR or two-stage IBBR. The primary endpoint was quality of life. In the present article, we assessed the effect of the procedure on the occurrence of adverse outcomes. Analyses were performed with logistic regression and the general linear model. The trial is registered in the Dutch National Trial Register (NTR TC 5446) and the public CCMO register in the Netherlands (NL41125.029.12). The inclusion of patients is completed. Results: Between April 14, 2013, and May 29, 2015, 140 patients were enrolled in the study. Eventually, 59 patients (91 breasts) in the one stage IBBR group and 59 (87 breasts) in the two-stage IBBR group were included for analysis. The overall medical complication rates (38.5% vs 10.3%, OR = 6.28, p = 0.001), the medical re-operation rates (32.6% vs 9.6%, OR = 3.96, p = 0.009) and the implant explantation rates (27.0% vs 2.4%, OR = 15.17, p = 0.001) were significantly higher in the one-stage group. This remained the case after controlling for multiple confounding factors (p < 0.001). Conclusions: Immediate one-stage ADM-assisted IBBR was associated with a significantly higher rate of post-operative complications compared with two-stage IBBR. There was no evidence of adverse tissue reactions to the ADM itself. These results indicate that immediate one-stage ADM-assisted IBBR should be considered very carefully.

Group A included 63 patients who underwent 70 immediate Surgimesh-PET-assisted breast reconstructions, and group B included 133 patients who underwent 136 standard breast reconstructions.RESULTS: No significant differences between groups occurred for early postoperative complications (p = 0.610), major complications that required surgical revision (p = 0.887), volume (p = 0.498) or width of the prosthesis (p = 0.201), skin-sparing mastectomy (p = 0.315), or axillary surgery (p = 0.265). Multivariate logistic regression showed that prior radiotherapy was the only significant variable for early postoperative complications in both whole series (p = 0.011) and group B (p = 0.046), whereas body mass index greater than 25 was an independent predictor in group A (p = 0.041). Prior radiotherapy was the only variable that reached statistical significance in the multivariate model for major complications in the whole series (p = 0.005).CONCLUSIONS: Short-term outcomes of Surgimesh-PET-based alloplastic breast reconstruction are promising. Further studies are needed to evaluate the long-term results of this surgical approach.CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.BACKGROUND: Although the introduction of acellular dermal matrices is considered one of the most important advancements in alloplastic breast reconstruction, costs and local policy limit their use in Italy.

Three types of matrix have been used for 402 of these procedures. The present study aimed to compare the use and outcome of Permacol, Strattice and Veritas to assist implantbased breast reconstruction. Methods: Cases of implant-based breast reconstruction using Permacol, Strattice and Veritas ACMs performed in Edinburgh were analysed with 6 months follow up. Results: Permacol (P), Strattice (S) and Veritas (V) were used in 72, 220 and 110 breast reconstructions respectively. Patient and breast weight, indications for mastectomy and proportion of bilateral cases did not differ between groups. Smoking, use of chemotherapy, incision used, associated axillary surgery, nipple preservation and use of fixed volume implant or expander did vary between groups apparently reflecting changes in practice over time. Rates of postoperative erythema varied significantly between groups (P 15.3%, S 7.7%, V 0.9%, chi = 13.6, p = 0.0011). Surgeons ranked materials V 1, S 2 and P 3 (chi-35.3, p < 0.0001). There was no difference in rates of unplanned surgery at 6 months (P 25%, S 27.7%, V 31.8%, chi = 1.1, p = 0.58) or implant loss at 6 months between groups (P 12.4%, S 11.4% and V 12.5% , chi = 0.1, p = 0.95). Conclusions: While differences exist in the characteristics of ACMs available to assist implant-based breast reconstruction and surgeons have clear preferences, there were no differences in outcome in terms of failure rate or unplanned reoperations in the present study.

In this study, we examined whether different processing methods for the ADMs lead to a disparity in histologic, clinical, and financial outcomes after breast reconstruction. Thirty patients undergoing implant-based breast reconstruction were randomized into AlloMax or AlloDerm arms (n = 15, each). ADM was placed at the time of immediate reconstruction. Patients were evaluated for complications on postoperative days 7, 14, and 30. During implant exchange, ADM biopsies were taken and compared histologically for vascular and cellular infiltration. Patient satisfaction was evaluated using the BRECON-31 questionnaire 1 year after implant exchange. A cost analysis was performed comparing the two ADMs. Patient demographics and complication rates were similar between the two groups (p > 0.05). Histologically, vessel density and fibroblast/inflammatory cell infiltrate were greater on the dermal side than on the implant side (p < 0.01) in both ADMs, suggesting greater vascular and cellular in-growth from the dermal side. Vessel density in the middle portion of the Allomax biopsies was significantly higher than the same site in the Alloderm biopsies (p < 0.05). The extent of fibroblast/inflammatory cell infiltration was similar in both arms (p > 0.05). The BRECON-31 satisfaction questionnaire yielded similar responses across all metrics between the two study arms. The negotiated price was slightly different when comparing the two ADMs, with no significant difference in ADM reimbursement. In this study, AlloDerm RTU and AlloMax were successfully used for implant-based breast reconstruction with comparable outcomes.

The primary outcome was SSI, as defined by CDC criteria. Operative and postoperative protocols were standardized. Secondary endpoints included clinical outcomes up to 1 year and all implant loss, or reoperation.RESULTS: There were 112 TE-IBR patients (180 breasts) using ADM who were randomized into 2 study arms, with 62 patients in the 24-hour group and 50 in the extended group. Surgical site infection was diagnosed in 12 patients in the 24-hour group and 11 in the extended group (19.4% vs 22.0%, p = 0.82). The extended group had 7 patients who required IV antibiotics and an overall implant loss in 7 patients (14.0%). The 24-hour group had 4 patients who required IV antibiotics, with 3 requiring removal (4.8%). Patients with diabetes, postoperative seroma, or wound dehiscence were all more likely to develop SSI (p < 0.02).CONCLUSIONS: In a randomized controlled noninferiority trial, 24 hours of antibiotics is equivalent to extended oral antibiotics for SSI in TE-IBR patients. Additional multicenter trials will further assess this important aspect of TE-IBR postoperative care.BACKGROUND: Closed-suction drains, implants, and acellular dermal matrix (ADM) are routinely used in tissue expander-based immediate breast reconstruction (TE-IBR). Each of these factors is thought to increase the potential for surgical site infection (SSI). Although CDC guidelines recommend only 24 hours of antibiotic prophylaxis after TE-IBR, current clinical practices vary significantly. This study evaluated the difference in SSI between 2 different prophylactic antibiotic durations.

Aim of our study was to achieve one-stage immediate implant based breast reconstruction, using biological matrices after conservative mastectomies, evaluate patients outcome and complications, in patients suffering from stage Tis-T1-T2 (<3 cm) breast cancer who underwent conservative mastectomy and reconstructive surgery. Methods. The inclusion criteria were: aged 20-65 years; nonsmokers; no diabetes or systemic connective disease; BMI<30; Patients should not be subjected to post-mastectomy radiotherapy; informed consent. During our study, through a randomization system, we used two different types of acellular dermal matrices (ADM): SurgiMend and Tutomesh. Results. From February 2012 to March 2014, 22 patients were enrolled, for a total of 38 reconstructions (average age 49 years). Ten patients did not have any mesh-related complications. Four patients showed a dehiscence with bilateral implant exposure, which required removal of the implants; minor wound dehiscence (healing within a month) was observed in 4 patients; 2 patients presented an asymmetry of the inframammary folds and a hematoma was found in two patients. Conclusion. The introduction of the ADM has helped to overcome several reconstructive limitations, allowing an immediate prosthetic reconstruction, after a conservative mastectomy. Complications have been drastically reduced due to an accurate selection of patients. In conclusion, one-stage breast reconstruction with acellular biological matrices, in selected patients, may be a new and realistic frontier in breast surgery, with the real possibility of providing women with breast cancer, a better quality of life compared to the traditional two-stage reconstruction.

The Braxon mesh which comes pre-shaped completely wraps the implant which is placed on the muscle, without detaching the pectoralis major. It is rehydrated in saline in 10 minutes. Results: A total of 22-patients underwent mastectomy and Braxon ADM plus implant reconstruction, 5 bilateral and 17 unilateral; a total of 27 reconstructions. The rate of implant loss was 3.7% (n = 1 due to wound breakdown), seroma 14% (n = 4) and infection 0%. Excellent cosmetic outcomes so far were obtained with a low complication rate.

We did a prospective randomised trial to compare the safety of IBBR with an ADM immediately after mastectomy with that of two-stage IBBR. Methods: We did an open-label, randomised, controlled trial in eight hospitals in the Netherlands. Eligible women were older than 18 years with breast carcinoma or a gene mutation linked with breast cancer who intended to undergo skin-sparing mastectomy and immediate IBBR. Randomisation was done electronically, stratified per centre and in blocks of ten to achieve roughly balanced groups. Women were assigned to undergo one-stage IBBR with ADM (Strattice, LifeCell, Branchburg, NJ, USA) or two-stage IBBR. The primary endpoint was quality of life and safety was assessed by the occurrence of adverse outcomes. Analyses were done per protocol with logistic regression and generalised estimating equations. This study is registered at Nederlands Trial Register, number NTR5446. Findings: 142 women were enrolled between April 14, 2013, and May 29, 2015, of whom 59 (91 breasts) in the one-stage IBBR with ADM group and 62 (92 breasts) in the two-stage IBBR group were included in analyses. One-stage IBBR with ADM was associated with significantly higher risk per breast of surgical complications (crude odds ratio 3.81, 95% CI 2.67-5.43, p<0.001), reoperation (3.38, 2.10-5.45, p<0.001), and removal of implant, ADM, or both (8.80, 8.24-9.40, p<0.001) than two-stage IBBR. Severe (grade 3) adverse events occurred in 26 (29%) of 91 breasts in the one-stage IBBR with ADM group and in five (5%) of 92 in the two-stage IBBR group. The frequency of mild to moderate adverse events was similar in the two groups. Interpretation: Immediate one-stage IBBR with ADM was associated with adverse events and should be considered very carefully. Understanding of selection of patients, risk factors, and surgical and postsurgical procedures needs to be improved. Funding: Pink Ribbon, Nuts-Ohra, and LifeCell. Copyright © 2016 Elsevier Ltd.

The primary endpoint was clinical infection by postoperative day 30. Secondary endpoints included all other complications encountered throughout the follow-up period and culture data. Demographic data recorded included patient age, body mass index, diabetes, smoking, chemotherapy, radiation, and follow-up. Procedural data recorded included procedure type, procedure length, estimated blood loss, use of acellular dermal matrix, use of muscle flap, and inpatient versus outpatient setting.RESULTSFrom March 2010 through January 2012, 107 women were randomized and 102 completed the study. Five patients were determined not to be candidates for reconstruction after randomization. There were 43 patients in the Reusable Group and 59 patients in the Disposable Group. There were no significant differences in patient demographic data, procedural data, or the type of procedure performed between groups. In the Reusable Group, there were 5 infections (12%) within 30 days compared to 0 (0%) infections in the Disposable Group (P = 0.012). There was no significant difference in secondary complications. There was a trend for positive wound cultures (11% vs. 3%, P = 0.10) and positive drape cultures (17% vs.4%, P = 0.08) in patients with clinical infection. There were no differences in the number of colony-forming units or positive cultures between groups.CONCLUSIONSDisposable draping material is superior to a reusable draping system in the prevention of clinical infection within the immediate postoperative period. This study did not demonstrate a clear link between intraoperative culture data and the development of clinical infection. A completely disposable gown and draping system is recommended during implant-based breast reconstruction.BACKGROUNDClinical infection remains a significant problem in implant-based breast reconstruction and is a physical and emotional strain to the breast reconstruction patient. Bacterial strikethrough of draping and gown material is a likely source of infection. Strategies to reduce infection in implant-based breast reconstruction are essential to improve patient outcomes.

Seventy-nine patients were enrolled between April 2014 and August 2015 all over Europe using a single protocol for patient selection and surgical procedure, according to the Association of Breast Surgery and British Association of Plastic Reconstructive and Aesthetic Surgeons joint guidelines for the use of acellular dermal matrix in breast surgery. The preshaped matrix completely wraps the breast implant, which is placed above the pectoralis major, without detaching the muscle. A total of 100 prepectoral breast reconstructions with complete implant coverage were performed. This series, with mean follow-up of 17.9 months, had two cases of implant loss (2.0%) including one necrosis of the nipple and one wound breakdown (1.0% respectively). No implant rotations were observed. Good cosmetic outcomes were obtained with natural movement of the breasts and softness to the touch; none of the patients reported experiencing pain or reduction in the movements of the pectoralis major muscle postoperatively. The use of preshaped acellular dermal matrix for a complete breast implant coverage in selected patients is safe and gives satisfactory results, both from the aesthetic view point and the low postoperative complication rates. Further studies reporting long-term outcomes are planned. Copyright © 2017 Wiley Periodicals, Inc.

Bilateral reduction mammaplasty was performed in 50 patients. The method of closure (sutures versus skin adhesive) applied to each breast was determined randomly, using each patient as her own control. Scars were assessed by the patient and by a blinded panel, at 1 week, 6 weeks, and 6 months after surgery, using a visual analogue scale, the modified Hollander Wound Evaluation Scale, and the Patient and Observer Scar Assessment Scale.RESULTSBoth patients and panelists expressed an overall preference for the adhesive side as of 1 week after surgery. Patients' visual analogue scale scores for scar comfort and scar appearance and panelists' visual analogue scale scores for aesthetic outcome were significantly better for the adhesive side after 6 weeks and 6 months (p < 0.05), as was the total Hollander Wound Evaluation Scale score of the panelists after 6 weeks (p < 0.02). The total Patient and Observer Scar Assessment Scale score after 6 months was significantly better for the adhesive side according to the patients (p < 0.01), but not according to the panelists (p = 0.11).CONCLUSIONThe authors conclude that 2-octyl-cyanoacrylate is a sound alternative for wound closure.BACKGROUND2-Octyl-cyanoacrylate skin adhesive may be used for surgical wound closure. However, its use in plastic surgery has not been properly assessed.

Objectives: Differences between HADM and native breast capsule specimens were evaluated by immunohistochemical analysis of key inflammatory markers involved in capsule formation. Methods: Twenty consecutive patients underwent immediate, 2-stage, implant-based breast reconstruction with dual-plane HADM. During tissue expander-implant exchange, full-thickness biopsies of biointegrated HADM and native breast capsule (internal control) from the tissue-expander envelope were obtained. Immunohistochemical analysis was performed for endothelial cells (CD31), B cells (CD20), T cells (CD3), macrophages (CD68), collagen I and III, and myofibroblasts (a-smooth muscle actin). Observed levels of marker labeling were semiquantitatively scored from 0 (none) to 3 (severe) by a blinded histopathologist and were statistically analyzed with the Wilcoxon rank sum test. Results: A bilateral sample was obtained from 1 patient; all other samples were unilateral. Compared with capsule samples from native breast tissue, HADM samples had significantly lower levels of all inflammatory markers (P <.001). Conclusions: These lower levels of inflammatory markers support previous evidence that HADM may inhibit inflammatory and profibrotic signaling characteristics of breast capsule development and decrease the risk of capsular contracture. Further investigation is needed to determine the mechanism by which HADM inhibits these inflammatory cells, whether HADM reduces the incidence of breast capsular contracture, and if so, the longevity of this effect.

Each of these factors is thought to increase the potential for surgical site infection (SSI). Although CDC guidelines recommend only 24 hours of antibiotic prophylaxis after TE-IBR, current clinical practices vary significantly. This study evaluated the difference in SSI between 2 different prophylactic antibiotic durations. Study Design A noninferiority randomized controlled trial was designed in which TE-IBR patients received antibiotics either 24 hours postoperatively or until drain removal. The primary outcome was SSI, as defined by CDC criteria. Operative and postoperative protocols were standardized. Secondary endpoints included clinical outcomes up to 1 year and all implant loss, or reoperation. Results There were 112 TE-IBR patients (180 breasts) using ADM who were randomized into 2 study arms, with 62 patients in the 24-hour group and 50 in the extended group. Surgical site infection was diagnosed in 12 patients in the 24-hour group and 11 in the extended group (19.4% vs 22.0%, p = 0.82). The extended group had 7 patients who required IV antibiotics and an overall implant loss in 7 patients (14.0%). The 24-hour group had 4 patients who required IV antibiotics, with 3 requiring removal (4.8%). Patients with diabetes, postoperative seroma, or wound dehiscence were all more likely to develop SSI (p < 0.02). Conclusions In a randomized controlled noninferiority trial, 24 hours of antibiotics is equivalent to extended oral antibiotics for SSI in TE-IBR patients. Additional multicenter trials will further assess this important aspect of TE-IBR postoperative care.

This was carried out in UK and Europe. Methods: All patients who underwent muscle-sparing breast reconstruction since 2014 were included in the study. The pre-shaped Braxon ADM completely wraps the implant after rehydration in saline for 5 minutes. The ADM with the implant is placed on the muscle, without detaching the pectoralis major. Results: A total of 110 patients had Braxon ADM plus implant reconstruction. 70 patients had unilateral and 20 patients had bilateral procedures. Complications included an implant loss of 1.8%; wound necrosis of 0.9% and 3.6% wound dehiscence. The short-term outcomes have been excellent, with high patient satisfaction, less pain, a more natural shape and feeling and good cosmetic outcomes.

Detaching pectoralis major from the chest wall in the subpectoral technique is associated with postoperative pain. Prepectoral implant based reconstruction using a novel preshaped ADM mesh ''BRAXON'' has recently been introduced in the UK. We report the early experience from 3 Breast Units using this technique in immediate breast reconstruction. Methods: Patients requiring immediate breast reconstruction suitable for Braxon from December 2015 to October 2016 were included. Information regarding demographics, indication for surgery, operative details, immediate and delayed complications and follow up details were collected and analysed. Results: A total of 78 cases were identified of which 13 were bilateral procedures. Their BMI ranged from 19-39 kg/m2. Four patients were diabetic and 3 were smokers. Implant size used ranged from 200-535cc and the average length of stay in the hospital was 1.6 days. During the median follow up of 28 weeks, 16 patients (20%) had seromas aspirated and 20 patients (25%) required a further course of antibiotics. Seventeen patients (22%) were readmitted within 30 days and 8 implants (10%) were explanted due to infection (2 bilateral procedures). Conclusion: Our early experience using this novel technique has shown the complication rates comparable to the traditional subpectoral technique. Post-operative recovery is quicker and animation deformity is eliminated as pectoralis muscle is spared. However, long term studies are required to assess rippling and impact from adjuvant treatment.

We assessed rates of post-operative infection, unplanned return to theatre, readmission and implant loss at three months with a multi-centre study in North West England to compare with the quality criteria set in ABS/BAPRAS Oncoplastic Breast Reconstruction Guidelines for Best Practice. Methods: A retrospective review of implant based reconstructions, in 5 centres, between 01/01/12 and 31/12/12 was performed. Unplanned readmission, return to theatre, infection and implant loss at three months were assessed. Results: 191 patients underwent implant based breast reconstruction. 58 (30%) pedicle flap, 16 (8%) dermal sling, 48 (25%) ADM and 68 (36%) implant alone. Complication rates are largely comparable to Best Practice guidelines (table 1), however infection rates (determined by reference to clinical signs of infection or further use of antibiotics) are high at 29 (15%). Conclusion: Although our sample size is relatively small, the standard set in the ABS/BAPRAS guidelines for implant loss appears achievable in unselected breast units. The high infection rate undoubtedly reflects our broad definition of infection and retrospectively collected data, however this represents an area where improvement is required. Standardising practice with an evidenced-based 'Theatre Infection Checklist' to ensure best practice recommendations are followed may improve outcomes. (Table Presented).

The patients were registered from September 1991 through February 1995 at 51 institutions in the Kinki district of Japan. All patients had stage I, II, or IIIa breast cancer with four or more lymph-node metastases and underwent mastectomy. CAF therapy and UFT+TAM therapy were started within 4 weeks after surgery. CAF therapy consisted of CPA (100 mg/day) on days 1 to 14, followed by 2 weeks of rest, plus ADM (20 mg/m(2)/day) on days 1 and 8 and 5-FU (300 mg/m(2)/day) on days 1 and 8. A total of 6 courses were delivered. UFT+TAM therapy consisted of 3 years of UFT (400 mg/day) plus TAM (20 mg/day), given daily. CAF therapy and UFT+TAM therapy were each assigned to 82 patients. The 5-year survival rate was significantly higher in the UFT+TAM group (82.1%) than in the CAF group (66.2%; p=0.04, logrank test). The 5-year relapse-free survival rate was higher in the UFT+TAM group (61.8%) than in the CAF group (46.3%; p=0.07, logrank test). As for adverse events, the rates of leukopenia, anorexia, nausea and vomiting, general malaise, and hair loss were lower in the UFT+TAM group than in the CAF group. These results suggest that long-term treatment with UFT+TAM may be a useful alternative adjuvant therapy for the management of breast cancer, especially in elderly patients.

The outcome is reported of a study encompassing 109 pre- and 297 postmenopausal evaluable cases with previously untreated metastatic breast cancer. The patients were randomized either to a concurrent chemo/hormonotherapy or to the hormonal treatment alone, chemotherapy being delayed until the occurrence of tumor progression. All patients were further randomized to 3 chemotherapy regimens (LMFP, LMP/FVP, LMFP/ADM) representing three different degrees of intensity. Pre-menopausal patients tend to live longer with the concurrent combination of both modalities, whereas postmenopausal patients fare better when chemotherapy is delayed until the occurrence of tumor progression with hormonotherapy alone. However, the differences in survival are statistically significant only in postmenopausal patients with a less aggressive tumor ("low-risk"). The more aggressive cytotoxic combinations elicit higher response rates than "minimal chemotherapy", but the differences translate only marginally into different survivals. These findings are discussed with regard in particular to their importance in establishing widely acceptable therapeutic rules for the treatment of advanced breast cancer.

Aim: To look at all our mastectomies and immediate reconstructions and see whether they have been coded properly on the OPCS system Method: All skin sparing mastectomies and immediate reconstructions with ADM/Implant that were performed over a 6 month period were taken from our central database and the OPCS and HRG codes were compared and to look at the reason why they were inappropriately coded. Results: There were 24 cases covering all 3 consultants. 9 achieved the correct HRG code (JA16Z Mastectomy and reconstruction - 6415). The remaining cases did not get a reconstruction HRG but instead JA07 and JA06 codes which are the HRGs usually assigned to mastectomies. The lost income on these 15 cases alone is about 80,000. Conclusion: Interventions were made and a re-audit will be performed of coding and HRG allocation for 3 months after these interventions.
