Heterotopic gastric mucosa associated with jejunal atresia

Abstract

An infant born at 35 weeks' gestation with type 2 jejunal atresia underwent resection of the atretic ends of the bowel and primary anastomosis. Histologic examination of the resected distal bowel segment revealed heterotopic gastric mucosa (HGM). The infant was treated with an H2 blocker (Ranitidine) which was discontinued after a 99mTc pertechnetate radioisotope scan showed no residual heterotopic gastric mucosa. The child is asymptomatic and thriving at 2 years of age. HGM is a rare finding in the jejunum and its association with intestinal atresia has only been reported in five cases, three of whom had duodenal atresia as part of the Mitchell-Riley syndrome. This case highlights the importance of histologic examination of the resected bowel in intestinal atresia and demonstrates one approach to managing this unexpected finding.
