Gastric emptying of a 51Cr labelled solid meal was studied before and at least 6 months after operation for pyloric-prepyloric ulcer disease. All patients underwent an antrectomy, selective gastric vagotomy but 10 were randomized to a gastroduodenostomy and 12 to a Roux-en-Y gastrojejunostomy. There was no significant difference in the emptying rate between patients studied preoperatively (T 75 = 48 +/- 21.8 min) and those investigated after a Billroth I gastroduodenostomy (T 75 = 45 +/- 15.8 min). However, the emptying rate was significantly retarded in the Roux-en-Y patients as compared to those studied preoperatively (T 75 + T 50 + T 25). In the former group, an initial retardation of emptying of the meal was most apparent (T 75 = 89 +/- 81.7 min). Due to a high standard deviation, the difference between the Roux-en-Y and gastroduodenostomy groups did not reach statistical significance. Our results would indicate that retarded gastric emptying is not a regular phenomenon after a Roux-en-Y gastrojejunostomy provided that a selective gastric vagotomy had been performed and the investigation been carried out at least 6 months after the operation.
对51铬标记固体餐的胃排空情况在幽门-幽门前溃疡病手术前及术后至少6个月进行了研究。所有患者均接受了胃窦切除术、选择性胃迷走神经切断术，但10例随机接受胃十二指肠吻合术，12例接受Roux-en-Y胃空肠吻合术。术前研究的患者（T75 = 48 +/- 21.8分钟）与接受毕罗一世胃十二指肠吻合术后研究的患者（T75 = 45 +/- 15.8分钟）之间的排空率无显著差异。然而，与术前研究的患者相比，Roux-en-Y患者的排空率明显延迟（T75 + T50 + T25）。在前一组中，餐食排空的初始延迟最为明显（T75 = 89 +/- 81.7分钟）。由于标准差较高，Roux-en-Y组与胃十二指肠吻合术组之间的差异未达到统计学意义。我们的结果表明，如果进行了选择性胃迷走神经切断术且在手术后至少6个月进行调查，Roux-en-Y胃空肠吻合术后胃排空延迟并非常见现象。
