Abstract：
BACKGROUND: Weight loss failure after bariatric surgery imposes great stress on patients and surgeons and great costs on healthcare systems. The literature review shows that weight loss failure is the most common cause of redo bariatric surgery. Therefore, identifying the predictors of weight loss failure in patients in the early stages can help bariatric surgeons. The present study aims to determine the association between primary weight loss and long-term weight loss outcomes.
METHODS: This retrospective cohort study was conducted on 329 patients undergoing OAGB who were followed for 60 months. For the prediction of short-term (24 months) and long-term (60 months) successful weight loss and weight regain, we used %TWL and BMI at any regular follow-ups.
RESULTS: In preoperative indices, age, sex, DLP, hypothyroidism, and HTN were not significant to predict successful short-term and long-term weight loss but %TWL at 12 months is a significant predictor of successful weight loss in short-term and long-term follow up. In the prediction of weight regain, preoperative indices (except BMI) were not significant but 12-month %TWL was a significant predictor.
CONCLUSIONS: This index can help surgeons find these patients early and provide helpful instructions to manage their issues more promptly to reach better weight loss outcomes.

摘要：
背景：减肥手术后的减肥失败给患者和外科医生带来了巨大的压力，给医疗保健系统带来了巨大的成本。文献综述显示，减肥失败是重做减肥手术的最常见原因。因此,在早期阶段确定患者体重减轻失败的预测因素可以帮助减肥外科医生。本研究旨在确定主要体重减轻与长期体重减轻之间的关系。
方法：这项回顾性队列研究对329例接受OAGB的患者进行了60个月的随访。对于短期（24个月）和长期（60个月）成功减肥和体重恢复的预测，我们在任何定期随访中使用%TWL和BMI。
结果：在术前指标中，年龄,性别,DLP,甲状腺功能减退,和HTN对预测成功的短期和长期体重减轻并不重要，但12个月时的%TWL是短期和长期随访中成功体重减轻的重要预测指标。在体重恢复的预测中，术前指标(BMI除外)不显著,但12个月TWL%是显著预测指标.
结论：该指数可以帮助外科医生及早发现这些患者，并提供有用的指导，以更迅速地管理他们的问题，从而达到更好的减肥效果。
