Abstract

Brunner's gland hamartomas are rare, benign duodenal tumors. But, they are the commonest hamartomas in the small intestine and believed to represent hyperplasia of Brunner's glands, perhaps in response to excessive gastric acid secretion. Brunner's gland hamartomas are usually smaller than 1cm and asymptomatic, incidental finding during endoscopy or radiographic examination. We report a case of large Brunner's gland hamartoma which prolapsed into gastric antrum and caused gastric outlet obstruction, and was resected by endoscopic polypectomy.
