Table 1_Analysis of factors affecting the postoperative drainage in patients with abdominoplasty with circumferential liposuction.docx

BackgroundAbdominoplasty combined with circumferential liposuction serves as a reliable and indispensable method for aesthetic body contour. This study aims to investigate the factors that influence drainage volume and duration after the procedure.
MethodsA retrospective study of 89 patients who received abdominoplasty with circumferential liposuction between January 2021 and October 2024 was conducted. Total drainage volume and duration were recorded. Univariable and multivariable linear regression and correlation analyses were utilized to identify the correlation between postoperative drainage and patient-related, and operation-related variables.
ResultsThe mean total drainage volume was 420.6 ± 220.8 ml, and the mean drainage duration was 6.8 ± 1.9 days. Based on the univariate and multivariate linear regression analysis, several statistically significant associations were identified. BMI (p = 0.001), volume of lipoaspirate (p = 0.001), and weight of resected tissue (p < 0.001) were significantly associated with the drainage volume. BMI (p < 0.001), operation time (p < 0.001), volume of lipoaspirate (p < 0.001), and weight of resected tissue (p = 0.01) were risk factors influencing drainage duration.
ConclusionsBMI, volume of lipoaspirate, and weight of resected tissue were associated with drainage volume and duration. Operation time was an independent factor influencing drainage duration.

背景：腹壁成形术联合环形吸脂术是美学形体塑形领域可靠且不可或缺的手术方式。本研究旨在探讨该术后引流液量及引流时长的影响因素。
方法：本研究对2021年1月至2024年10月期间接受腹壁成形术联合环形吸脂术的89例患者开展回顾性研究。记录所有患者的总引流液量与引流时长，采用单变量及多变量线性回归与相关性分析，探究术后引流情况与患者自身相关因素、手术相关因素之间的关联。
结果：本研究中患者的平均总引流液量为420.6±220.8 ml，平均引流时长为6.8±1.9天。经单变量与多变量线性回归分析，共检出多项具有统计学意义的关联：体重指数（Body Mass Index, BMI）（p=0.001）、吸出脂肪组织量（p=0.001）以及切除组织重量（p<0.001）与引流液量显著相关；BMI（p<0.001）、手术时长（p<0.001）、吸出脂肪组织量（p<0.001）以及切除组织重量（p=0.01）则为影响引流时长的危险因素。
结论：BMI、吸出脂肪组织量与切除组织重量同时与引流液量及引流时长相关，而手术时长则为影响引流时长的独立危险因素。
