Abstract

The rising prevalence of obesity and bariatric surgery has led to an increased demand for reconstructive body contouring procedures. Despite growing expertise and well-established surgical techniques, postoperative complications remain a significant challenge. This study analyses postoperative complications and potential risk factors.In a prospective cohort study, data from 606 patients who had undergone reconstructive body contouring surgery were collected between 2015 and July 2024. Focusing on abdominal contouring procedures, we analysed complication rates and their influencing factors, including BMI, resection weight, and type of weight loss (bariatric surgery vs. lifestyle modification). Statistical analysis was performed using the Mann-Whitney U test, chi-square test, and ROC curve analysis.The overall rate of postoperative complications was 37.5%, with wound healing disorders being most common (21.5%). Patients who had undergone bariatric surgery experienced significantly more complications than those who had lost weight through lifestyle changes (p=0.029). A higher BMI at the time of surgery (cut-off: 31) and a disproportionately high resection weight relative to BMI (index>105) were significant predictors of postoperative complications (p<0.001).These findings underscore the importance of individualised preoperative planning that accounts for factors such as BMI and resection volume. A resection weight-to-BMI index may serve as a useful tool for future risk assessment in abdominal contouring surgery, with the potential to optimise surgical outcomes, minimise complications, and facilitate transparent benchmarking.

减肥后形体整形手术:术后并发症及影响因素分析
肥胖和减肥手术的流行率不断上升,导致对重建身体轮廓手术的需求增加。尽管越来越多的专业知识和完善的手术技术,术后并发症仍然是一个重大挑战。本研究分析术后并发症及潜在危险因素。在一项前瞻性队列研究中,研究人员收集了2015年至2024年7月期间606名接受过重塑身体轮廓手术的患者的数据。以腹部轮廓手术为重点,我们分析了并发症发生率及其影响因素,包括BMI、切除体重和体重减轻类型(减肥手术与生活方式改变)。统计学分析采用Mann-Whitney U检验、卡方检验和ROC曲线分析。术后并发症发生率为37.5%,其中伤口愈合障碍最为常见(21.5%)。接受过减肥手术的患者比通过改变生活方式减肥的患者出现了更多的并发症(p=0.029)。手术时较高的BMI(截止值:31)和相对于BMI不成比例的高切除体重(指数>105)是术后并发症的重要预测因素(p
