Safer procedures for performing endoscopic papillectomy on papillary tumors should be established. Fourteen patients underwent endoscopic papillectomy between January 2000 and February 2007. Before papillectomy, tumors were slightly elevated by submucosal injection of glycerol, followed by semi‐circular mucosal incision of the anal border of the lesion in five cases. In nine cases, balloon‐catheter‐assisted endoscopic snare papillectomy was performed. All patients routinely underwent endoscopic nasobiliary drainage tube placement in the bile duct. A pancreatic stent was inserted only in patients with non‐patent minor papilla. The rate of positive margins was lower in patients who received balloon‐catheter‐assisted papillectomy than in patients who received papillectomy without a balloon catheter. Of three patients with local recurrence, only one patient required surgery. Post‐procedural complications included hemorrhage in eight patients, pancreatitis in one patient, and perforation in one patient. No perforation occurred after submucosal injection and mucosal incision. In three of four patients with early hemorrhage, bleeding was noticed as hemobilia through the nasobiliary drainage tube; this appears to be useful for early diagnosis of bleeding. No pancreatitis occurred in patients with patent minor papilla, suggesting that pancreatic stent placement is unnecessary in patients with patent minor papilla.
