A Case of Hyperplastic Polyp in the Duodenal Bulb, in which Endoscopic Ultrasonography was Useful for Determination of the Choice of Treatment

Abstract

A 62-year-old female was admitted to our hospital for the purpose of endoscopic polypectomy of the duodenal polyp.
Gastrointestinal fiberscopy and endoscopic ultrasonography (EUS) revealed a granular pedunculated polyp on the anterior wall of the duodenal bull. EUS demonstrated that the polyp was limited to the mucosal layer with retained continuity of the submucosal layer, and it contained some low echoic regions.
An endoscopic polypectomy was performed after drawing out the polyp into the stomach. The resected polyp was round in shape, with partially nodular surface, about 30×17×10mm in size. Histologically, hyperplasia of the proper duodenal epithelial cells was noted.
It is suggested that endoscopic ultrasonography is an armament for determination of indication of endoscopic polypectomy.
