The purpose of the present study was to compare gastric emptying in two groups of dogs in which a gastrojejunal or duodenojejunal Roux-en-Y anastomosis was performed over the site of an experimental obstruction in the distal duodenum. The experiment was carried out on 10 mongrel dogs. Gastric emptying was assessed twice in each dog before the experiment (control examination); the solid phase of the test meal was labelled with 99mTc. Following a control examination, the dogs were divided into two groups of 5 animals each, and subjected to the above mentioned surgical procedures. Postoperative gastric emptying was carried out 3 weeks after the operation, and then at 3 and 6 months following the procedure. The following parameters describing quantitatively gastric emptying were determined: mean transit time MTT0-60. MTT0-120 and total mean transit time MTT0-180. The comparison of these parameters revealed statistically significant differences confirming delay of gastric emptying in dogs with a gastrojejunal anastomosis.
本研究的目的是比较两组犬的胃排空情况，这两组犬在十二指肠远端实验性梗阻部位进行了胃空肠或十二指肠空肠Roux-en-Y吻合术。实验在10只杂种犬身上进行。在实验前（对照检查），对每只犬的胃排空情况进行了两次评估；测试餐的固相用99mTc标记。对照检查后，将犬分为两组，每组5只动物，并进行上述手术操作。术后3周进行胃排空检查，然后在术后3个月和6个月进行检查。确定了以下定量描述胃排空的参数：平均通过时间MTT0-60、MTT0-120和总平均通过时间MTT0-180。这些参数的比较显示出统计学上的显著差异，证实了胃空肠吻合术犬的胃排空延迟。
