To examine if preoperative weight loss correlates to postoperative weight loss 2 and 3 years after surgery.
A review was conducted of bariatric surgery patients who underwent either gastric bypass or sleeve gastrectomy during 2015-2018 and had 3-year follow-up data. Demographic and outcome data were collected. A best-fit regression model for weight loss was constructed.
Eight hundred fifty-nine patients underwent surgery during the selected period, of which 199 patients (23%) were analyzed. Eighty-two percent of patients had gastric bypass and 82% were female. Preoperative percent excess weight loss (%EWL) was not significantly associated with 2- and 3-year postoperative %EWL ( = 0.18). Patients demonstrated significant weight regain at 3 years postoperatively versus 1 year ( < 0.01). Higher preoperative weight loss was associated with lower %EWL 3 years postoperatively versus 1 year ( = 0.04). Postoperative %EWL had a significant negative association with higher preoperative weight, diabetes, baseline use of a mobility device, and sleeve gastrectomy.
In a cohort of bariatric surgery patients, there was no statistically significant association between preoperative and midterm postoperative %EWL. Postoperative %EWL was negatively associated with several patient-specific factors and increasing time since operation.
研究术前体重减轻与术后2年和3年体重减轻之间是否存在关联。
对2015年至2018年期间接受胃旁路手术或袖状胃切除术并拥有3年随访数据的肥胖症手术患者进行了回顾。收集了人口统计学和结果数据。构建了一个最佳拟合的体重减轻回归模型。
在选定期间有859例患者接受了手术，其中199例患者（23%）被纳入分析。82%的患者接受了胃旁路手术，82%为女性。术前超重体重减轻百分比（%EWL）与术后2年和3年的%EWL无显著相关性（=0.18）。与术后1年相比，患者在术后3年出现了显著的体重反弹（<0.01）。与术后1年相比，术前体重减轻较多与术后3年较低的%EWL相关（=0.04）。术后%EWL与较高的术前体重、糖尿病、基线使用移动辅助设备以及袖状胃切除术存在显著负相关。
在一组肥胖症手术患者中，术前和术后中期的%EWL之间没有统计学上的显著关联。术后%EWL与几个患者特定因素以及术后时间增加呈负相关。
