Background. Many insurance companies require obese patients to lose weight prior to gastric bypass. From a previous study by the same authors, preoperative weight at surgery is strongly predictive of weight loss up to one year after surgery. This review aims to determine whether preoperative weight loss is also correlated with weight loss up to one year after surgery. Methods. Of the 186 results screened using PubMed, 12 studies were identified. A meta-analysis was performed to further classify studies (A class, B class, regression, and rejected). Results. Of all 12 studies, one met the criteria for A class, six were B class, four were regression, and one was rejected. Six studies supported our hypothesis, five were inconclusive, and no study refuted. Conclusions. Preoperative weight loss is additive to postsurgery weight loss as predicted from the weight at the time of surgery.
背景。许多保险公司要求肥胖患者在接受胃旁路手术前减肥。同一组作者之前的一项研究表明，手术时的术前体重是术后长达一年体重减轻的有力预测指标。本综述旨在确定术前体重减轻是否也与术后长达一年的体重减轻相关。方法。在使用PubMed筛选的186项结果中，确定了12项研究。进行荟萃分析以进一步对研究进行分类（A类、B类、回归分析和排除）。结果。在所有12项研究中，一项符合A类标准，六项为B类，四项为回归分析，一项被排除。六项研究支持我们的假设，五项尚无定论，没有研究反驳。结论。术前体重减轻与根据手术时体重预测的术后体重减轻相加。
