AbstractBackgroundThe Goldilocks mastectomy procedure involves local contouring of completely autologous breast tissue created by preserving and de‐epithelializing the residual mastectomy flaps. The purpose of this study was to provide outcomes data for 96‐Goldilocks mastectomy procedures analyzing indications, complications, relevant comorbidities, and adjuvant cancer treatment impacting reconstructive and aesthetic outcomes.MethodsComprehensive review of every patient who underwent Goldilocks mastectomy from 2012 to 2018 included relevant medical and surgical comorbidities, as well as complication profiles. Aesthetic outcomes were also assessed in those with postoperative imaging available.ResultsA total of 53 patients (96 breasts) were included in this study. Bilateral cases consisted of 81.1% of the total cohort (n = 86 cases), and 18.9% (n = 10 cases) were unilateral procedures. Mean age at the time of reconstruction was 55.8 (33‐77) years. Mean body mass index (BMI) at the time of reconstruction was 33.7 (19.2‐54.6). The overall complication rate was 9.38% (seroma = 2, hematoma = 1, cellulitis = 2, wound dehiscence = 3, and operating room take back = 1).ConclusionsGoldilocks breast reconstruction is a safe, effective option in patients with higher than average BMI or excess local breast tissue, or in patients meeting these criteria preferring a single‐stage reconstruction. This study qualifies its use in patients with higher than average risk factors for more extensive reconstructive modalities.

ABSTRACT Background Penile prostheses are commonly used to achieve erectile rigidity after phalloplasty in trans masculine patients. Implantation poses significant challenges because of the delicate nature of the neophallus and lack of native erectile tissue. Many groups have developed novel phalloplasty and prosthesis insertion techniques, but none have proven superior. Aim To analyze and aggregate reported characteristics and outcomes of penile prosthesis implantation in the trans masculine patient. Methods A comprehensive literature search of Medline, EMBASE, and Cochrane Registry databases was conducted for studies published through February 19, 2019, with multiple search terms related to penile prosthesis use in gender-affirming surgical procedures. Outcomes Studies were included and tabulated if they reported prosthesis outcomes in patients who received a neophallus as part of a gender-affirming procedure. Results 23 journal articles met inclusion criteria from 434 references identified. All selected articles were either retrospective or case series/reports. A total of 1,056 patients underwent phalloplasty, and 792 received a penile prosthesis. Most (83.6%) of the prostheses were inflatable, whereas 16.4% were non-inflatable. The number of cylinders used for each prosthesis was 61.0% single-cylinder and 39.0% double-cylinder. The mean follow-up duration was 3.0 years. Of patients who received a prosthesis, 36.2% reported a prosthesis complication; at follow-up 60.0% of patients had their original implant present, and 83.9% reported achieving penetration. Clinical Implications Prosthesis implantation in gender-affirming operations poses significant risk of complication, but it is still a reasonable and useful method to achieve rigidity necessary for sexual intercourse. Strength & Limitation This is the first study to aggregate all reported penile prosthesis characteristics and outcomes in trans masculine patients. This study was significantly limited by inconsistent reporting of demographics, sensation, urinary health, patient satisfaction, and penetrative sex. The lack of comparative studies precluded any meaningful meta-analytical comparison. Conclusions There is a great need for a prosthesis designed to meet the specific needs of the trans masculine patient after phalloplasty. Standardized methods of reporting implant outcomes including sexual function, sensation, and patient satisfaction should be refined for future studies. This study can assist patients and surgeons about the risks and benefits of this procedure.

Background Acquired defects of the cranium represent a reconstructive challenge in patients with calvarial bone loss due to trauma, infection, neoplasia, congenital malformations, or other etiologies. The objective of this study was to compare postoperative rates of infection, local complications, and allograft failures following cranioplasty reconstruction using titanium mesh (Ti), polymethyl methacrylate (PMMA), polyether ether ketone (PEEK), and Norian implants in adult patients. Methods This constitutes the first systematic review of available literature on 4 different methods of alloplastic cranioplasty reconstruction, including Ti, PMMA, PEEK, and Norian implants, using the Newcastle-Ottawa Quality Assessment Scale guidelines for article identification, screening, eligibility, and inclusion. Electronic literature search included Ovid MEDLINE/PubMed, EMBASE, Scopus, Google Scholar, and Cochrane Database. Pearson exact test was utilized at P < 0.05 level of significance (J.M.P. v11 Statistical Software). Results A total of 53 studies and 3591 patients (mean age, 40.1 years) were included (Ti = 1429, PMMA = 1459, PEEK = 221, Norian = 482). Polymethyl methacrylate implants were associated with a significantly higher infection rate (7.95%, P = 0.0266) compared with all other implant types (6.05%). Polyether ether ketone implants were associated with a significantly higher local complication rate (17.19%, P = 0.0307, compared with 12.23% in all others) and the highest ultimate graft failure rate (8.60%, P = 0.0450) compared with all other implant types (5.52%). Conclusions This study qualifies as a preliminary analysis addressing the knowledge gap in rates of infection, local surgical complication, and graft failure in alloplastic cranioplasty reconstruction with different implant types in the adult population. Longer-term randomized trials are warranted to validate associations found in this study.

Background: Interest in facial masculinization surgery is expected to increase as gender-affirming surgery becomes more widely accepted and available. The purpose of this study is to summarize the current literature describing operative techniques in facial masculinization surgery and provide an algorithmic approach to treating this patient population. Methods: PubMed, EMBASE, and Medline databases were queried for literature on operative techniques and outcomes of facial masculinization surgery in transgender and cisgender patients, published through July 2018. Data on patient demographics, follow-up, operative techniques, complications, and outcomes were collected. Results: Fifteen of the 24 identified studies met inclusion criteria. Two studies discussed the outcomes of 7 subjects (6 trans-male and 1 cis-male) who underwent facial masculinization procedures. No objective outcomes were reported in either study; however, subjects were generally satisfied and there were no complications. The remaining studies reviewed operative techniques utilized in the cisgender population. Conclusion: A summary of considerations for each facial anatomic subunit and respective operative techniques for facial masculinization is presented. Current facial masculinization procedures in cisgender patients may be considered in the transgender patient population with favorable outcomes. However, further research is needed on techniques and objective outcome measures of facial masculinization procedures in the transgender population.

Background The purpose of this study is to describe our experience and outcomes in oncoplastic pelvic reconstruction for patients who underwent either vertical rectus abdominis musculocutaneous (VRAM) or omental flap following abdominoperineal resection (APR) at a single tertiary care institution. Methods All patients who underwent pelvic reconstruction following APR with either VRAM or omental flaps from January 1992 to January 2017 were retrospectively reviewed. Patient demographics and relevant comorbidities including chemotherapy and radiation therapy data were collected and analyzed. In addition, margin status at the time of oncologic resection was analyzed. Flap-specific data were collected for each approach. Oncologic data collected included cancer type, stage at time of APR, and rate of tumor recurrence within the flap. Results A total of 562 patients were identified who underwent pelvic reconstruction with either VRAM or omental pedicle flaps. Of these, 274 (48.8%) underwent VRAM reconstruction and 288 (51.2%) underwent omental flap reconstruction. All margins were negative at time of cancer ablation surgery. Complications data included: seroma (VRAM = 2 [0.36%]; omentum = 32 [5.69%], p < 0.0001), wound dehiscence (VRAM = 31 [5.52%]; omentum = 17 [3.02%], p = 0.022), abscess (VRAM = 4 [0.71%]; omentum = 27 [4.8%], p < 0.0001), cellulitis (VRAM = 2 [0.36%]; omentum = 10 [1.78%], p = 0.025). Statistical comparison of tumor recurrence between these two reconstructive approaches showed a significantly higher recurrence rate in omental flaps compared with VRAM flaps (p = 0.000127). Conclusion The results of this study suggest a significantly higher tumor recurrence rate in omental flap pelvic reconstruction compared with VRAM flaps. This knowledge has the potential to influence surgical planning and flap selection in pelvic reconstruction.

Background Dendritic cells (DCs) are bone marrow-derived, professional antigen-presenting cells with tolerogenic function. The ability of DCs to regulate alloantigen-specific T cell responses and to promote tolerance has aligned them ideally for a role in vascularized composite allotransplantation (VCA). In this study, we summarize the current evidence for DC therapies for tolerance induction to alleviate the requirement for chronic immunosuppression. Method A comprehensive and structured review of manuscripts published on VCA was performed using the MEDLINE and PubMed databases. All eligible studies published from the year 2000 to 2017 were included in the final results. Result Nineteen original preclinical and clinical studies that employed cell therapy for VCA were included in this review. In vivo DC therapy was found to direct the alloimmune response toward either transplant rejection or tolerance in VCA models. While injection of mature DCs rapidly increases T-cell activity in humans and promotes transplant rejection, the injection of immature DCs acts as an immunosuppressant and inhibits T-cell activity. In addition to immature DCs, mesenchymal stem cells were also found to have a positive effect on allotransplantation of solid organs and bone marrow via cytokine expression which decreases the alloreactive effector lymphocytes and increases CD4+/CD25+/FoxP3 Tregs. Despite the promising findings, the efficacy of cell-based therapies varies greatly across studies, partly due to different methods of cell isolation and purification techniques, source, route and timing of administration, and combination immunosuppressive therapy. Conclusion Additional research is needed to evaluate the efficacy and safety of DC and other cell-based therapeutic measures in human allotransplant recipients. Future direction will focus on the development of novel methods to reduce immunosuppression and develop more individualized management, as well as the clinical application of basic research in the mechanisms of immunologic tolerance.

AbstractCarotid endarterectomy (CEA) reduces the risk of stroke in patients with internal carotid artery stenosis, although the optimal surgical technique is debated. The literature suggests that patch angioplasty reduces complication risk, although primary closure shortens cross-clamp time and eliminates complications associated with grafts.The objective of this study was to assess the complication rate after CEA with primary closure.Retrospective review of 240 consecutive patients between 2002 and 2010. Of these patients, 70% returned for follow-up visits for at least 2 or more years.Primary closure was used in all patients. The average cross-clamp time was 18 minutes. Complications in the immediate postoperative period within 30 days were as follows: stroke (n = 3; 1.1%), transient ischemic attack (TIA; n = 4; 1.5%), myocardial infarction (MI; n = 3; 1.1%), and death (n = 1; 0.4%). Short-term follow-up revealed eight patients who were found to have significant restenosis (>80%) by carotid duplex imaging. Two to ten year postoperative complication rates were as follows: stroke (n = 7; 4.2%), TIA (n = 7; 4.2%), amaurosis fugax (n = 1; 0.6%), MI (n = 8; 4.8%), and death (n = 28; 17%). Mortality was due to stroke or heart attack (n = 2; 1.2%), cancer (n = 7; 4.2%), and unknown causes (n = 19; 11%).This study presents our experience with complications after primary closure after CEA. In our experience, CEA is a safe and effective surgical means of preventing stroke in the short term. Well-designed prospective studies are needed to confirm specific patient characteristics in which primary closure and patch angioplasty are indicated.
