    Abstract:
    BACKGROUND/AIMS: Sporadic non-ampullary duodenal neoplasms are rare and optimal treatment for these lesions remains undefined. Endoscopic resection of duodenal neoplasms is widely used recently and it is an alternative treatment strategy to surgical excision. This study aimed to evaluate the safety and efficacy of endoscopic resection of duodenal neoplasms and to determine its outcomes. METHODS: Patients who underwent endoscopic resection for non-ampullary duodenal neoplasms between January 2005 and December 2014 were analyzed retrospectively. Data including size, morphology, histology, location and endoscopic procedural technique were reviewed. The main outcome measurements were success rate, complication, recurrence and follow-up assessments. RESULTS: The study included 33 patients with duodenal neoplasms. The mean size of resected lesion was 8.58 mm. The results of histologic examination were as follows: 23 (69.7%) adenomas, 2 (6.1%) adenocarcinoma, 3 (9.1%) Brunner's gland tumor and 3 (9.1%) neuroendocrine tumor. Tubular adenoma was the most common type (63.6%) of non-ampullary duodenal neoplasms. Eighteen (54.5%) lesions were found in the second portion of the duodenum, and 10 (30.3%) lesions on bulb and 3 (9.1%) lesions on superior duodenal angle. Of the 33 cases, 32 (97.0%) were managed by endoscopic mucosal resection technique during a single session and one case was managed by endoscopic submucosal dissection (ESD). One episode of perforation occurred after ESD. During a median follow-up period of 5.76 months, recurrence was observed in only one case of in a patient with tubular adenoma. CONCLUSIONS: Endoscopic resection of duodenal neoplasm is a safe and effective treatment modality that can replace surgical resection in many cases. Careful endoscopic follow-up is essential to manage recurrence or residual lesions.
