The role of gastrin in duodenal ulcer surgery.

The role of gastrin and of serum gastrin analysis in duodenal ulcer disease and duodenal ulcer surgery is analysed. As far as etiology and pathogenesis are concerned up to now gastrin has never been shown to play a significant role. Neither does it provide any diagnostic help in the typical duodenal ulcer disease (but it will allow for diagnosis of the retained antrum after Billroth II resection and of the Zollinger Ellison syndrome). Gastrin determination therefore is not helpful in the choice of the correct operative procedure for the ulcer disease. In today's clinical practice its major role consists in the control of surgical results. This is illustrated by a prospective randomized study on proximal selective vagotomy with and without pyloroplasty. In these patients serum gastrin analysis has shown that the omission of pyloroplasty is not followed by antral stasis. It furthermore always exhibits the typicel vagotomy profile, although vagotomy is incomplete in the 2-DODG-test.
