This is a report of a clinical investigation of weight gain occurring after initial good weight loss following an operation performed to treat morbid obesity. The reasons for weight gain or poor weight loss after the first operation, the indications for a second operation, and the effectiveness and complications of four different "second" operations were examined. Thirty-five patients who were weight loss failures, a subgroup of 556 patients upon whom one of five bariatric operations had been performed, provided the clinical material for this investigation. The findings indicate that technical and nontechnical patient factors are responsible for the failure of the initial bariatric operation. The most effective second operation to treat weight loss failures was gastric bypass with Roux-en-Y gastrojejunostomy (GBRY). More difficult to perform than when done as the first bariatric operation, GBRY when done as a second operation is associated with a higher complication rate.
这是一份关于病态肥胖手术治疗后最初体重良好减轻后体重增加的临床调查研究报告。研究探讨了首次手术后体重增加或体重减轻不佳的原因、二次手术的指征，以及四种不同“二次”手术的有效性和并发症。35例减肥失败患者作为临床研究对象，他们是556例接受过五种减肥手术之一的患者中的一个亚组。研究结果表明，技术和非技术的患者因素是初次减肥手术失败的原因。治疗减肥失败最有效的二次手术是 Roux-en-Y 胃空肠吻合术式的胃旁路手术（GBRY）。GBRY作为二次手术比作为初次减肥手术更难实施，且并发症发生率更高。
