[Recurrent ulcer after gastric resection (author's transl)].

A retrospective study was made of 34 cases of recurrent ulcer following gastric resection. Males, especially above the age of 40, were shown to be particularly susceptible. The intact vagus apparently plays the most important role in the pathogenesis. Radiological examination and endoscopy are of the greatest diagnostic importance. Truncal vagotomy must be regarded as the treatment of choice in uncomplicated recurrent ulcer. Resection procedures are indicated in perforating ulcer, gastrojejunocolic fistula, antral remains and Zollinger-Ellison syndrome.
