title: [Assessment of Endoscopic Resection and Partial Duodenectomy for Duodenal Mucosal Tumor].
abstract: BACKGROUND
  The risk of perforation following endoscopic resection is high. We analyzed the outcome of partial duodenectomy and discussed the therapeutic strategy for duodenal mucosal tumor(DMT).
  
  
  METHODS
  We analyzed 19 cases who have undergone endoscopic resection, and 11 cases who have undergone partial duodenectomy for DMT in our institute since 2007. We divided them into the first period(ESD actively indicated)and late period(ESD carefully indicated according to the alteration of indication of ESD for DMT in 2013)groups.
  
  
  RESULTS
  In the first period, all 17 cases initially underwent endoscopic resection and 4 cases were complicated by perforation. On the other hand, in the late period, 6 of 12 cases initially underwent endoscopic resection and 1 case was complicated by perforation. Emergent partial duodenectomy was performed with additional resection in the perforation cases. There were no complications associated with surgery, and all 29 cases achieved curative resection, based on the histology results.
  
  
  CONCLUSIONS
  We can safely indicate endoscopic resection for DMT with surgical back-up and cooperation with the endoscopic internal department.
