title: Balloon-catheter-assisted endoscopic snare papillectomy for benign tumors of the major duodenal papilla.
abstract: BACKGROUND
  Adenomas of the major duodenal papilla are considered premalignant and should be resected completely. Endoscopic snare papillectomy has been recognized as a safe and feasible treatment. An endoscopic snare papillectomy technique was devised using a balloon catheter inserted into the common bile duct to more efficiently resect papillary tumors en bloc.
  
  
  METHODS
  Two patients with benign adenoma of the major duodenal papilla were included in this study. A balloon catheter linked to a snare was inserted into the bile duct via the accessory channel of a duodenoscope, and snare resection was performed after pulling the expanded balloon toward the duodenal lumen.
  
  
  RESULTS
  En bloc papillectomy was successfully performed, leaving the lateral margin free of tumor as confirmed microscopically. No complications were observed in either case.
  
  
  CONCLUSIONS
  Given an appropriate indication, balloon-catheter-assisted endoscopic snare papillectomy is a useful technique for the treatment of tumors of the major duodenal papilla.
