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 (MBSAQIP) databases were queried for patients with body mass index (BMI) ≥35 kg/m2 undergoing bariatric surgery from 2017-2022. Outcomes included BMI and obesity-related comorbidities before and 1 year after bariatric surgery. Paired Breast Reconstruction Risk Assessment (BRA) scores were analyzed to evaluate risk modulation before and after bariatric surgery in the setting of microvascular breast reconstruction., Results: A total of 1,026 patients were included with an average age of 47 and BMI of 44.7 kg/m2. Comorbidities included hypertension (601, 59%), type 2 diabetes (291, 28%), and cardiovascular disease (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 BRA risk analysis for microvascular breast reconstruction before and after bariatric surgery showed reduction in 30-day surgical complications (40.4% vs. 24.8%, P<0.0001), with an absolute risk reduction (ARR) of 15%, relative risk reduction (RRR) of 36%, and a number needed to treat (NNT) of 7. Each 1 kg/m2 reduction in preoperative BMI was associated with a 3.4% reduction in surgical complications (P<0.0001)., Conclusions: There is potential efficacy for metabolic bridge therapy in reducing complications for obese patients undergoing microvascular breast reconstruction., Competing Interests: Financial Disclosure Statement: The authors have no financial conflicts of interest to disclose., (Copyright © 2024 by the American Society of Plastic Surgeons.)

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 R 2 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 R 2 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., (Copyright © 2023 by the American Society of Plastic Surgeons.)
