Two hundred consecutive patients undergoing surgical intervention for morbid obesity had either the gastric bypass or the vertical banded gastroplasty. Both groups were similar in patient composition. In the vertical banded gastroplasty patients, operating room time was lessened by 70 minutes, blood loss lessened by 225 mL, and hospital stay shortened by two days as compared with the gastric bypass patients. At 30 months, a 64-percent mean excess weight loss was observed in the gastric bypass vs a 56-percent mean excess weight loss in the vertical banded gastroplasty group. The vertical banded gastroplasty procedure is preferred because there is no late stomal dilation with weight gain, no vitamin B(12) deficiency, and most important, this procedure leaves the remainder of the stomach and duodenum available for endoscopic and radiologic evaluation.
200名因病态肥胖接受手术干预的连续患者分别接受了胃旁路手术或垂直束带胃成形术。两组患者的构成相似。与接受胃旁路手术的患者相比,接受垂直束带胃成形术的患者手术时间减少了70分钟,失血量减少了225毫升,住院时间缩短了两天。在30个月时,胃旁路手术组平均超重减轻了64%,而垂直束带胃成形术组平均超重减轻了56%。垂直束带胃成形术更受青睐,因为体重增加时不会出现晚期吻合口扩张,不会出现维生素B12缺乏,而且最重要的是,该手术使胃和十二指肠的其余部分可用于内镜和放射学评估。
