Peptic ulcer in children with gastric tube interposition

Abstract

An infrequent, but potentially serious, complication of gastric tube interposition is ulceration within the conduit. It is important, therefore, to recognize ulcer formation in its early stages by serial radiographs throughout the childhood years. While redundancy and partial obstruction with impaired drainage of the tube appear to be etiologic factors, distension of the transposed antrum may lead to hyperacidity and may play a role in ulcerogenesis. A course of dietary and antacid therapy may heal the ulcer, but surgical revision of the tube may prove necessary.
