Abstract

The effects of proximal gastric vagotomy on the gastric electrical and contractile activities and on gastric emptying of solid food were studied in dogs. Proximal gastric vagotomy produced only minimal alteration of the electrical activity and did not significantly alter the response of the electrical and contractile activities to vagal stimulation (insulin) and local stimulation (food). Barium meal studies showed no delay in gastric emptying time after proximal gastric vagotomy but significant delay after truncal vagotomy. The findings support the clinical impression that gastric motility and empyting (solid) remain relatively normal after proximal gastric vagotomy.

摘要

在犬类动物中研究了近端胃迷走神经切断术对胃电活动、收缩活动以及固体食物胃排空的影响。近端胃迷走神经切断术仅使电活动产生极小改变，且未显著改变电活动和收缩活动对迷走神经刺激（胰岛素）及局部刺激（食物）的反应。钡餐研究显示，近端胃迷走神经切断术后胃排空时间无延迟，但全胃迷走神经切断术后则出现显著延迟。这些发现支持了临床印象，即近端胃迷走神经切断术后胃动力和（固体食物）排空仍相对正常。
