Background: Obese patients experience more complications after autologous breast reconstruction. This study evaluates how bariatric surgery modulates risk of complications in the setting of microvascular breast reconstruction. Methods: Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program databases were queried for patients with body mass index (BMI) greater than or equal to 35 kg/m2 undergoing bariatric surgery from 2017 to 2022. Outcomes included BMI and obesity-related comorbidities before and 1 year after bariatric surgery. Paired Breast Reconstruction Risk Assessment scores were analyzed to evaluate risk modulation before and after bariatric surgery in the setting of microvascular breast reconstruction. Results: A total of 1026 patients were included with an average age of 47 and BMI of 44.7 kg/m2. Comorbidities included hypertension (n = 601 [59%]), type 2 diabetes (n = 291 [28%]), and cardiovascular disease (n = 10 [1%]). One-year outcomes after bariatric surgery included an average BMI of 32.7 kg/m2, with remission of type 2 diabetes in 29% of patients. Paired Breast Reconstruction Risk Assessment analysis for microvascular breast reconstruction before and after bariatric surgery showed reduction in 30-day surgical complications (40.4% versus 24.8%; P < 0.0001), with an absolute risk reduction of 15%, a relative risk reduction of 36%, and a number needed to treat of 7. Each 1-kg/m2 reduction in preoperative BMI was associated with a 3.4% reduction in surgical complications (P < 0.0001). Conclusion: There is potential efficacy for metabolic bridge therapy in reducing complications for obese patients undergoing microvascular breast reconstruction.

Abstract Background The presence of a chimeric gracilis and profunda artery perforator (PAP) flap with a common arterial pedicle has been demonstrated on computed tomography angiography in up to 59% of patients and confirmed in a cadaveric model. Already utilized for head and neck reconstruction by Heredero et al, this novel flap could provide more volume than either flap alone which is advantageous, particularly in patients with sizable defects. The purpose of this study was to determine the average tissue volume that can be utilized from this chimeric flap. Methods CT Angiogram imaging studies exhibiting chimeric flap anatomy were reviewed over a 7-year period at a single institution utilizing Visage Version 7.1, a radiology picture archiving and communication system. This software was used to trace the flap pedicles and to capture estimated soft tissue volumes of each respective flap. Results A total of 31 patients, consisting of 52 lower extremity gracilis and PAP chimeric flaps, underwent tissue volume analysis. The average total volume of soft tissue supplied by the gracilis flap was found to be 70.21 cm3 (standard deviation [SD] = 26.99). The average volume of the PAP flap was 31.73 cm3 (SD = 26.12). The average total volume captured by the chimeric gracilis and PAP flap was 101.94 cm3 (SD = 62.40). Conclusion The potential soft tissue volume that can be harvested from a chimeric gracilis and PAP flap is significantly greater than solitary gracilis or PAP flaps. This chimeric flap may serve as a viable and advantageous reconstructive option for patients requiring large volume soft tissue coverage, particularly if other sizable options are not available.

Background: There is limited research on the impact of revisional surgery after breast reconstruction on patient experience and postoperative quality of life (QoL). Methods: Patients undergoing mastectomy with immediate implant-based or autologous free-flap breast reconstruction from 2008 to 2020 were reviewed. These patients were categorized by revisions (0–1, 2–3, and 4+) and surveyed on QoL metrics using BREAST-Q and Was It Worth It? (WIWI) questionnaires. BREAST-Q QoL, satisfaction, and WIWI metrics between revision groups were evaluated. Results: Among 252 patients, a total of 150 patients (60%) underwent zero to one revisions, 72 patients (28%) underwent two to three revisions, and 30 patients (12%) underwent four or more revisions. Median follow-up was 6 years (range, 1–11 years). BREAST-Q satisfaction among patients with four or more revisions was significantly lower ( P = 0.03), while core QoL domains (chest physical, psychosocial, and sexual well-being) did not significantly differ. Analysis of unplanned reoperations due to complications and breast satisfaction showed no significant difference in QoL scores between groups ( P = 0.08). Regarding WIWI QoL metrics, four or more revisions were associated with a higher rate of worse QoL ( P = 0.035) and worse overall experience ( P = 0.001). Most patients in all revision groups felt it was worthwhile to undergo breast reconstruction (86%), would choose breast reconstruction again (83%), and would recommend breast reconstruction to others (79%). Conclusions: Overall, a majority of patients undergoing revisions after breast reconstruction still have a worthwhile experience. Although reoperations after breast reconstruction do not significantly impact long-term BREAST-Q QoL domains, patients undergoing four or more revisions have significantly lower breast satisfaction, worse QoL, and a postoperative experience worse than expected.

BACKGROUND: Although the overall psychosocial benefits and body image gains of postmastectomy breast reconstruction are well-established, there is limited information on how postoperative complications affect patient quality of life (QOL). STUDY DESIGN: A single-institution cross-sectional survey analysis was performed on patients who underwent postmastectomy breast reconstruction between 2008 and 2020. QOL was assessed using the BREAST-Q and the Was It Worth It questionnaires. The results were compared among patients who had major complications, minor complications, and no complications. Responses were compared using 1-way ANOVA and chi-square tests as appropriate. RESULTS: A total of 568 patients met inclusion criteria, and 244 patients responded (43% response rate). Most patients did not have any complications (n = 128; 52%), 41 had minor complications (17%), and 75 had major complications (31%). There were no differences in any of the BREAST-Q well-being metrics based on degree of complication. Across all 3 groups, patients reported that surgery was worthwhile (n = 212; 88%), they would choose reconstruction again (n = 203; 85%), and they would recommend it to a friend (n = 196; 82%). Overall, 77% reported that their overall experience either met or exceeded expectations, and 88% of patients had unchanged or improved overall QOL. CONCLUSIONS: Our study demonstrates that QOL and well-being are not negatively impacted by postoperative complications. Although patients who had no complications had an overall more positive experience, nearly two-thirds of all patients, no matter the degree of complication, stated that their overall experience either met or exceeded their expectations.

Background In response to the opioid epidemic, the United States declared a public health emergency in 2017. We evaluated pain medication prescribing practices among plastic and reconstructive surgeons, assessing pain medication prescription rates and opioid-related mortality both nationally and regionally within the United States. Methods A retrospective analysis of Medicare Part D prescriber data among plastic surgeons from 2013 through 2017 was conducted. Pain medications were categorized as opioid and nonopioid medications. Trends in surgeon prescribing habits were evaluated using the Cochrane-Armitage trend test. Results A total of 708,817 pain medication claims were identified: 612,123 claims (86%) were for opioid pain medications and 96,694 claims (14%) were for nonopioid pain medications. Total pain medication claims decreased from 44% of all medications in 2013 to 37% in 2017 (P < 0.001). Opioid medications decreased from 37% of total medication claims to 32% (P < 0.001). The overall opioid prescription rate fell from 1.53 claims per beneficiary in 2013 to 1.32 in 2017 (P < 0.001). Nonopioid pain medications decreased from 7% in 2013 to 6% in 2017 (P < 0.001); nonsteroidal anti-inflammatory drug claims increased by 44%. The prescription rate of nonopioid medications decreased from 2.40 claims per beneficiary in 2013 to 2.32 in 2017 (P < 0.001). An overall increase in opioid-related mortality was observed. Trends in pain medication prescriptions varied significantly among US regions and divisions. Conclusions Plastic surgeons are prescribing less opioids and relying more on nonopioid pain medications. Increased adoption of multimodal pain treatment approaches among surgeons is a likely explanation for this trend in face of the current opioid crisis.

Background: The purpose of this study was to evaluate monetary trends in Medicare reimbursement rates for 30 abdominal wall reconstruction surgical procedures over a 20-year period (2000 to 2020). Methods: The Physician Fee Schedule Look-Up Tool from the Centers for Medicare and Medicaid Services was used for each of the 30 included current CPT codes, and reimbursement data were extracted. Monetary data were adjusted for inflation to 2020 U.S. dollars using changes to the United States consumer price index. The R2 values for the average annual percentage change and the average total percentage change in reimbursement were calculated based on these adjusted trends for all included procedures. Results: After adjusting for inflation, the average reimbursement for all procedures decreased by 17.1% from 2000 to 2020. The greatest mean decrease was observed for CPT code 49568 (the implantation of mesh or other prosthesis for open incisional or ventral hernia repair or mesh for closure of débridement for necrotizing soft-tissue infection, −34.4%). The only procedure with an increased adjusted reimbursement rate throughout the study period was CPT code 20680 (+3.9%). From 2000 to 2020, the adjusted reimbursement rate for all included procedures decreased by an average of 0.85% each year, with an average R2 value of 0.78, indicating a stable decline throughout the study period. Conclusions: Reimbursement rates are declining when adjusted for inflation. Increased awareness of these trends is helpful to maintain access to optimal abdominal reconstruction care in the United States.
