本研究的目的是检测远端胃切除术后的胃肠动力和膳食粘度对胃排空的影响。本文观察了正常犬和胃二分之二切除Billroth-I或Roux-Y吻合术后不同粘度无热量餐的胃肠动力和胃排空。远端胃切除术后，胃排空取决于粘度的膳食，在正常的狗。由于十二指肠和空肠的收缩模式不同，Billroth-I组的无热量粘性餐排空速度明显快于Roux-Y组。与正常犬相比，Billroth-I组粘性食物的胃排空加快，Roux-Y组延迟。胃和肠的几个运动参数不同的正常和胃切除犬。因此，远端胃切除术后，膳食的粘稠度和小肠的收缩模式是胃排空的重要决定因素。
The aim of the study was to examine gastrointestinal motility ater distal gastrectomy and the influence of meal viscosity on gastric emptying. Gastrointestinal motility and gastric emptying of acaloric meals with different viscosities were measured in normal dogs and after a two-thirds gastrectomy with Billroth-I or Roux-Y gastroenterostomy. After distal gastrectomy, gastric emptying depended on the viscosity of the meal, as in normal dogs. Acaloric viscous meals emptied significantly faster in the Billroth-I than in the Roux-Y group due to different contractile patterns of the duodenum and jejunum. In comparison to normal dogs, gastric emptying of viscous meals was accelerated in the Billroth-I and delayed in the Roux-Y group. Several motility parameters of the stomach and intestine differed between the normal and gastrectomized dogs. Thus, after distal gastrectomy, the viscosity of the meal and the contractile patterns of the small intestine are important determinants of gastric emptying.
