Endoscopic polypectomy for duodenal bulb tumor has not been performed aggressively, because of the polypectomic technique in the narrow lumen being difficult, and having a high risk. We report two cases of duodenal bulb tumor removed safely by the endoscopic polypectomy.
Case 1 : A 44-year-old woman, who had a duodenal submucosal tumor located at the anterior wall of the duodenal bulb pointed out 4 years ago. Recently, the tumor grew up to 2.5cm in size, was elastic soft, and the pedunculated type. The tumor easily prolapsed into the stomach. The CT scanning revealed that the tumor was localized within the duodenal wall. An endoscopic polypectomy was performed in the stomach with a two-channeled endoscope. The histological examination revealed a Brunnerioma.
Case 2 : A 39-year-old man, who had a duodenal polyp located at the anterior wall of the doudenal bulb pointed out 10 years ago. Recently, the tumor grew up to 1.5cm in size, was elastic soft, and the semipedunculated type. An endoscopic ultrasonography revealed the main location of the tumor was in the mucosal layer. An endoscopic polypectomy was performed in the doudenal bulb. The histological examination revealed a hyperplasia of Brunner's gland.
