The current study aimed to examine the role of binge eating (BE) in explaining weight loss in patients undergoing laparoscopic adjustable gastric banding (LAGB) for severe obesity. Participants were 49 patients (13 males and 36 females) who completed questionnaires two weeks prior and three and six months after their operation. Predictor measures of weight loss included pre and postoperative BE and changes in BE following surgery. A decrease in BE as a consequence of having surgery was able to significantly predict postoperative weight loss. Many surgical services currently screen patients for BE at baseline to identify those most suitable for surgery. This study suggests that this process may be redundant as the results indicate that it is not the presence of BE pre- or post-operatively which are predictive of treatment-induced weight loss, but whether patients' BE behaviours decrease or persist in response to surgery. Future research therefore should seek to identify predictors of decreased BE following surgery in order to enhance candidate selection and improve the efficacy of this form of obesity management.
本研究旨在探讨暴食症（BE）在解释腹腔镜可调节胃束带术（LAGB）治疗重度肥胖患者体重减轻中的作用。参与者为 49 名患者（13 名男性和 36 名女性），他们在手术前两周和手术后三个月和六个月完成了问卷调查。体重减轻的预测指标包括术前和术后 BE 以及术后 BE 的变化。由于手术而减少 BE 能够显著预测术后体重减轻。许多外科服务机构目前在基线时对患者进行 BE 筛查，以确定最适合手术的患者。本研究表明，这一过程可能是多余的，因为研究结果表明，手术前后 BE 的存在与否并不能预测治疗引起的体重减轻，而是患者的 BE 行为是否在手术后减少或持续。因此，未来的研究应该寻求确定术后 BE 减少的预测因子，以增强候选者的选择，并提高这种肥胖管理形式的疗效。
