在判断选择性近侧迷走神经切断术(SPV)和选择性近侧迷走神经切断加幽门成形术疗效中,胃酸下降是明显有关指标。术后长期随诊可见胃底部粘膜壁细胞群恒定性减少,故而术后胃酸复原不能以此解释。为此,作者对尚保留神经供应的胃窦部(间接与泌酸功能有关)进行了形态学研究。本组病例包括十二指肠溃疡25例,胃溃疡12例和胃十二指肠复合溃疡5例。术前以及术后连续七年每隔1～2年均进行胃镜检查并予以五次取胃窦部远侧
In determining the efficacy of selective proximal vagotomy (SPV) and selective proximal vagotomy plus pylorus plasty, gastric acid decline is a significant relevant indicator. After a long-term follow-up, the consistency of the gastric mucosal cell population at the bottom of the stomach was reduced. Therefore, postoperative gastric acid recovery cannot be explained by this. To this end, the author performed a morphological study of the gastric antrum (indirectly related to oxyntic function) that still retains the supply of nerves. This group of patients included 25 cases of duodenal ulcers, 12 cases of gastric ulcers and 5 cases of gastric and duodenal complex ulcers. Gastroscopy was performed every 1 to 2 years before surgery and 7 consecutive years after surgery, and five distal antral antrums were taken.
