Gastric carcinoid following gastrojejunostomy.

A carcinoid tumor of the gastric body was found in a patient who had a gastrojejunostomy done for duodenal ulcer 36 years earlier. Association of gastric carcinoid with gastrojejunostomy has previously been described by Lemmer. In contrast, such tumors have never been observed when the more common surgical procedure for peptic ulcer was used, ie, gastric resection. On the basis of recent knowledge on gastric endocrine cells, the authors suggest a relationship between the gastrojejunostomy and the carcinoid tumor, probably related to an elevated gastrin release.
