Abstract

We present a case of a 76-year-old man with right upper quadrant abdominal pain and weight loss, who was found to have an intraductal papillary neoplasm of the bile duct (IPNB) of the pancreaticobiliary subtype, deemed curatively resectable. The patient declined surgery and opted for endoscopic therapy. He underwent two sessions of endoscopic retrograde cholangiopancreatography (ERCP)-guided radiofrequency ablation (RFA). Ten months later, no evidence of recurrence was identified on repeat ERCP. To our knowledge, this is the first reported case of successful use of RFA as a primary treatment modality for resectable IPNB.

Core tip: Intraductal neoplasms of the bile duct (IPNB) classically present with jaundice and/or pruritus, but nonspecific symptoms such as right upper quadrant discomfort and weight loss may also develop. The first-line treatment for these tumors is surgical resection. Endoscopic retrograde cholangiopancreatography-guided radiofrequency ablation (RFA) has historically been used as adjunctive treatment; self-expanding metal stents may be used for palliation. We report a case of successful primary treatment of an IPNB with RFA alone.
