From January 1982 to April 1984, 20 patients with lesser curvature gastroplasty had conversion to Roux-en-Y gastric bypass at the lesser curvature for failure to lose more than 50 per cent of excess body weight within 12 months of the original gastroplasty. The average excess weight of these patients before gastroplasty was 103 lb, and the average excess weight before conversion to gastric bypass was 73 lb. The average weight loss after gastric bypass was doubled within 6 to 15 months. Only one patient failed to lose weight after conversion to gastric bypass, and this patient had endocrine problems. Late surgical complications occurred in two patients (10%); one had cholecystectomy and the other had vagotomy and hiatus hernia repair. There were no mortalities in this series.
从1982年1月至1984年4月，20例小弯胃成形术患者因在初次胃成形术后12个月内未能减轻超过50%的超重体重，而转为小弯处的Roux-en-Y胃旁路术。这些患者在胃成形术前的平均超重为103磅，在转为胃旁路术前的平均超重为73磅。胃旁路术后6至15个月内平均体重减轻量翻倍。转为胃旁路术后只有1例患者未能减重，该患者存在内分泌问题。2例患者（10%）出现晚期手术并发症；1例行胆囊切除术，另1例行迷走神经切断术和食管裂孔疝修补术。该系列中无死亡病例。
