Bile duct radiofrequency ablation for a residual adenoma after endoscopic papillectomy.

Abstract

For residual or local recurrence of duodenal ampullary adenoma after endoscopic papillectomy, argon plasma coagulation (APC) has been reported to be useful; however, APC may be insufficient because deep or circumferential ablation in the distal bile duct is difficult to perform [1]. Recently, the usefulness of bile duct radiofrequency ablation (RFA) for residual adenomas has been reported, but the number of cases is still relatively small [2] [3]. We report a case in which bile duct RFA was performed on a residual adenoma after endoscopic papillectomy.
