Changes of cell population in the antrum after selective proximal vagotomy and pyloroplasty in gastroduodenal ulcer.

Abstract

A marked increase in the number and size of the antral gastrin cells and parietal cells could be shown in long term examinations of the antrum mucosa after SPV and pyloroplasty. Twenty-five patients with UD, 12 with UV and five with Dragstedt combination (UV and UD) were examined over a period of five to seven years. A significant correlation of parietal cell increase and a positive reaction to insulin was found. The findings were compared with the changes in the fundic mucosa, where a marked decrease of parietal cells occur after SPV.
