BACKGROUND: Most cases of @entity17314 have conventionally been treated by surgical resection. The aim of our study was to explore the feasibility of endoscopic resection in small duodenal @entity4303 . METHODS: The study population consisted of seven @entity1 with small duodenal @entity4303 . The diagnosis was confirmed by preoperative biopsies. The depth of @entity5 invasion was evaluated by endosonography. RESULTS: The @entity4303 was detected by endosonography in all cases. Size ranged ultrasonographically from 1.5 mm to 7 mm. Tumor invasion was confined to the submucosa in all @entity1 . Endoscopic resection was performed with the strip biopsy technique using a two-channel endoscope. In six @entity1 , the specimens were resected without severe complications. Five of them were confirmed histologically to be typical @entity4303 . In one @entity1 , @entity4303 was not detected histologically in the specimen. In the remaining @entity1 , a perforation occurred. However, the huge @entity1066 was managed conservatively. Follow-up endoscopy revealed no evidence of recurrent or @entity41 in any @entity1 . CONCLUSION: Small duodenal @entity4303 confined to the submucosa can be resected endoscopically and preoperative endosonography is necessary for the determination of endoscopic resectability.
