CHOLANGIOSCOPY-GUIDED RADIOFREQUENCY ABLATION TO TREAT BILIARY INTRADUCTAL PAPILLARY MUCINOUS NEOPLASIA

Video Transcription

Video Summary

This video presents a case of cholangioscopy-guided radiofrequency ablation (RFA) for biliary intraductal papillary mucinous neoplasia, a premalignant lesion. A 78-year-old man with a long bile duct stricture and high-grade dysplasia declined surgery, so RFA was used as an organ-preserving alternative. Two ablation sessions were performed with cholangioscopic confirmation of treatment effect, but disease recurred repeatedly. Eventually, the patient required right hepatectomy. The case suggests RFA may help selected non-operative patients, but durable control was not achieved in extensive, high-grade disease.
