ABSTRACT
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.

Mentions: Articles were obtained for the remaining abstracts and were further analyzed. Each article was expected to have more than ten patients in each group of study (preoperative weight loss versus weight gain) or >20 patients in a regression analysis. Information on pre/post-operation weight loss had to be available for article selection. Papers were also excluded that did not stratify the data such that gastric bypass weight loss results were separated from alternate weight loss procedures such as gastric banding or sleeve gastrectomy (Figure 1). The selected studies were further searched for their references to identify more papers pertaining to our study.
