Gender-Affirming Mastectomy: Psychosocial and Surgical Outcomes in Transgender Adults.

BACKGROUND: Limited literature exists examining the effects of gender-affirming mastectomy on transmasculine and nonbinary patients that is prospective and uses validated survey instruments. STUDY DESIGN: The psychosocial functioning of transmasculine and nonbinary patients was compared between patients who underwent gender-affirming mastectomy and those who had not yet undergone surgery. Participants were enrolled in a single-site, combined study of surgical and psychosocial outcomes, including a cross-sectional cohort of preoperative and postoperative patients, as well as separate prospective cohort. Participants completed the BREAST-Q psychosocial and sexual well-being modules, the BODY-Q satisfaction with chest and nipples modules, the Body Image Quality of Life Inventory, the Transgender Congruence Scale, the Patient Health Questionnaire-9, and the Generalized Anxiety Disorder-7 scale before and after surgery. We also examined how patient demographic factors correlated with postoperative surgical and psychosocial outcomes. RESULTS: A total of 111 transmasculine and nonbinary patients 18 to 63 years of age (mean ± SD 26.5 ± 8) underwent mastectomy and were included in the study. All were included in the cross-sectional cohort, and 20 were enrolled in the prospective cohort. More than one-third (34.2%) of patients were nonbinary. After surgery, psychosocial and sexual well-being, satisfaction, body image-related quality of life, and gender congruence were increased (p < 0.001) in both cohorts, and depression (p < 0.009 cross-sectional), and anxiety (p < 0.001 cross-sectional) were decreased. The most common adverse event was hypertrophic scarring, which occurred in 41 (36.9%) participants. CONCLUSIONS: In this study of transmasculine and nonbinary adults, gender-affirming mastectomy was followed by substantial improvements in psychosocial functioning.

Assessment of advanced age as a risk factor in microvascular breast reconstruction.

BACKGROUND: The population of elderly people is the fastest growing population in the United States. Because breast cancer typically affects the elderly population, surgeons will be performing more mastectomies in older patients. In this study, we evaluate the risks of microvascular breast reconstruction as a function of increasing age. METHODS: Between July 2002 and September 2009, a retrospective analysis of 818 free-flap breast reconstructions was used to assess the risk of age on surgical outcomes. Patient comorbidities, the American Society of Anesthesiologists (ASA) classification, and length of hospital stay were used to assess the rates of complications among our age cohorts. RESULTS: Advanced age was not associated with increased complications (P > 0.69). ASA class was a significant predictor of overall complications (P < 0.03) as well as the rate of fat necrosis (P < 0.01) and hematoma (P < 0.001). Flap loss occurred in 1.5% of operations, but there was no difference among the various age groups. Previous surgery was associated with an increased risk of flap loss (P < 0.001), and hypertension also increased the risk of thrombosis (P < 0.04). There was no difference in mean length of hospital stay (4.27 days). CONCLUSIONS: Advanced age should not be considered a risk factor for microvascular breast reconstruction. Because ASA status did predict overall surgical complications, surgeons should consider the patients' overall health status in deciding whether to operate.

Inclusion of mesh in donor-site repair of free TRAM and muscle-sparing free TRAM flaps yields rates of abdominal complications comparable to those of DIEP flap reconstruction.

BACKGROUND: Pedicled and free transverse rectus abdominis musculocutaneous (TRAM) flaps remain popular for autologous breast reconstruction, but the incidence of abdominal donor-site bulge and hernia is significantly greater when compared with deep inferior epigastric artery perforator (DIEP) flap reconstruction. Mesh repair after muscle harvest, however, may reduce the complication rate to that observed with perforator flaps alone. METHODS: A retrospective review of all free flap breast reconstructions at the University of California, Los Angeles Medical Center from 2002 to 2007 was performed. Abdominal bulge and hernia were noted for patients undergoing free TRAM and muscle-sparing free TRAM flap reconstructions and were compared with those observed following DIEP flap reconstructions. RESULTS: A total of 275 free TRAM plus muscle-sparing free TRAM flaps and 200 DIEP flaps were performed. Among patients with free and muscle-sparing free TRAM flaps, 11.3 percent were found to have postoperative abdominal bulge or hernia. Only 3.5 percent of DIEP flap patients had abdominal complications. Incorporating mesh into the rectus fascia repair significantly reduced the abdominal complications reported to 5.1 percent. Of the 86 free and muscle-sparing free TRAM flaps that were bilateral, 12.8 percent had hernias/bulges. Use of mesh with bilateral free and muscle-sparing free TRAM flaps reduced the complication rate to 3.7 percent. CONCLUSIONS: Incorporating mesh into rectus fascia repair in free and muscle-sparing free TRAM flap cases significantly reduces the rate of postoperative abdominal complications to levels equivalent to those for DIEP flap reconstructions. The authors advocate deciding intraoperatively between DIEP and muscle-sparing free TRAM flap dissections based on ease of dissection and whichever offers optimal safety and flap perfusion. Routine use of mesh in donor-site repair will decrease postoperative abdominal morbidity in unilateral and bilateral cases.

Risk factors for abdominal donor-site morbidity in free flap breast reconstruction.

BACKGROUND: The lower abdomen is the most popular donor site for autologous tissue breast reconstruction. Several studies have reported abdominal morbidity following pedicled and free flap reconstructions using this donor site, yet few studies have compared the various types of free flaps and investigated specific operative and patient-related factors that are associated with higher rates of abdominal complications. METHODS: The authors conducted a retrospective review of all free flap breast reconstructions performed at University of California Los Angeles Medical Center between July of 2002 and July of 2005. RESULTS: A total of 279 patients underwent 211 unilateral and 68 bilateral reconstructions, totaling 347 flaps. Eleven percent were free transverse rectus abdominis myocutaneous (TRAM) flaps, 52 percent were muscle-sparing free TRAM flaps, and 37 percent were deep inferior epigastric perforator (DIEP) flaps. Mean follow-up was 29.9 months. There were 30 total abdominal complications (10.9 percent of patients), including 17 rectus bulges and five hernias. Free TRAM reconstructions had a significantly higher rate of donor-site complications than did DIEP reconstructions. Bilateral flap harvests and obesity (body mass index >30) were significant risk factors for (1) any donor-site complication and (2) rectus bulge/hernia formation. There was no significant increase in donor-site complications associated with various prior abdominal operations. CONCLUSIONS: Donor-site complications are not uncommon, but paying careful attention to patient comorbidities when selecting an operative approach (bilateral versus unilateral, free TRAM versus DIEP, and so on) can minimize postoperative abdominal complications. Furthermore, the results corroborate the recent literature suggesting there is little functional difference in patients receiving muscle-sparing free TRAM versus DIEP reconstructions.
