Gastroduodenal involvement in chronic granulomatous disease of childhood.

Obstruction of the gastric outlet as a complication of chronic granulomatous disease (CGD) is uncommon. The usual findings in a barium examination of the upper gastrointestinal tract are irregular antral mucosal folds and antral narrowing. There is typically a sharp demarcation of the affected area from the normal proximal stomach. The authors report a case of CGD of childhood in which there was diffuse gastric involvement with extension into the duodenal cap. The patient recovered with conservative therapy after a diagnostic exploratory laparotomy.
