At the University of Alberta hospitals patients who underwent gastroplasty--horizontal, vertical with multistranded nylon banding of the stomas and vertical banded with Teflon reinforced stomas--have been followed up for over 2 years. Pouch volume ranged from 25 to 30 mL. Pouch volume and stoma size were measured radiologically 2 years after operation and correlated with the percentage excess weight loss. Any patient failing to lose at least 40% of the excess weight was considered a failure. There was no consistent correlation between pouch or stoma size and percentage excess weight loss for any of the three procedures studied. The failure rate for patients included in the study group was 33.3% for horizontal, 32.4% for vertical and 32.8% for vertical banded gastroplasty. The probable reason for the lack of correlation is that some patients change their diets so as to subvert the restriction imposed by the gastroplasty.
在阿尔伯塔大学医院，对接受胃成形术的患者进行了两年多的随访，这些患者接受的胃成形术包括水平胃成形术、带多股尼龙束带的垂直胃成形术以及带特氟龙加固造口的垂直胃成形术。胃袋容积在25至30毫升之间。术后两年通过放射学方法测量胃袋容积和造口大小，并将其与超重减轻百分比进行关联。任何未能减轻至少40%超重体重的患者被视为手术失败。在所研究的三种手术中，胃袋或造口大小与超重减轻百分比之间均无一致的相关性。研究组中水平胃成形术患者的失败率为33.3%，垂直胃成形术患者为32.4%，带垂直束带胃成形术患者为32.8%。缺乏相关性的可能原因是一些患者改变饮食，从而破坏了胃成形术所施加的限制。
