Gastric bypass (GBP; 227 cases) was compared with gastroplasty (GP; 189 cases) with a follow-up of six months to four years. After two years, mean weight loss of patients with GBP was 43.4 kg (34.2% of preoperative weight and 63.5% of excess weight loss), with a 5.7% failure rate. Corresponding results for those receiving GP were 27 kg (22.1% and 44.7 %), with a failure rate of 42.5%. The revision rate for GP (11.1%) was twice that for GBP (4.3%). There were two GBP and five GP perforations. There were two deaths among the 416 patients (0.48%), both in the GBP group. Gastric bypass was found to be more effective with fewer revisions than gastroplasty, but the mortality was higher. Roux-en-Y GBP is our current choice for surgical treatment of morbid obesity.
对227例接受胃旁路术（GBP）的患者与189例接受胃成形术（GP）的患者进行了比较，随访时间为6个月至4年。两年后，接受GBP的患者平均体重减轻43.4千克（占术前体重的34.2%，超重减轻的63.5%），失败率为5.7%。接受GP的患者相应结果为27千克（22.1%和44.7%），失败率为42.5%。GP的修正率（11.1%）是GBP（4.3%）的两倍。GBP有2例穿孔，GP有5例穿孔。416例患者中有2例死亡（0.48%），均在GBP组。结果发现，胃旁路术比胃成形术更有效，修正次数更少，但死亡率更高。Roux-en-Y胃旁路术是我们目前治疗病态肥胖的手术选择。
