The goal of most bariatric surgeons has been to construct small volume pouches in the proximal stomach to restrict the intake of food. The purpose of this study is to demonstrate that in addition to pouch volume, specific gastric pouch anatomy plays a significant role in weight loss.
The physical properties and dynamics of the pouch in our form of gastric bypass were compared with those in the most commonly performed bariatric procedures by creating a model. Our weight loss data were reviewed and compared with data reported in the literature.
According to LaPlace's and Poiseulle's Laws, a long narrow cylinder will have less wall tension and slower flow rate of material than a wider cylinder. Bariatric procedures with narrow pouches appear to produce better weight loss.
Long narrow pouches should have less tendency to enlarge and should delay the transit of material to a greater degree than wider pouches according to the LaPlace's and Poiseuille's Laws. Our data and the data of others strongly suggest that long narrow pouches are the most effective operations in bariatric surgery.
大多数减肥外科医生的目标是在胃近端构建小容量的胃袋以限制食物摄入。本研究的目的是证明，除了胃袋容量外，特定的胃袋解剖结构在体重减轻中也起着重要作用。
通过创建模型，将我们的胃旁路手术形式的胃袋的物理特性和动力学与最常用的减肥手术中的胃袋进行比较。我们回顾了体重减轻数据，并与文献中报道的数据进行了比较。
根据拉普拉斯定律和泊肃叶定律，长而窄的圆柱体比宽圆柱体具有更小的壁张力和更慢的物质流速。具有窄胃袋的减肥手术似乎能产生更好的体重减轻效果。
根据拉普拉斯定律和泊肃叶定律，长而窄的胃袋应该比宽胃袋更不容易扩大，并且在更大程度上延迟物质的转运。我们的数据和其他研究的数据强烈表明，长而窄的胃袋是减肥手术中最有效的术式。
