Feasibility of Percutaneous Transhepatic Cholangioscopy-Assisted Biliary Polypectomy for Intraductal Papillary Neoplasm of the Bile Duct

Effective local palliative treatment of intraductal papillary neoplasm of the bile duct using percutaneous transhepatic cholangioscopy-assisted biliary polypectomy. Feasible, safe, and successful in five patients, with technical and therapeutic success achieved. Patients with mucin-hypersecreting cast-like or polypoid type tumors benefited, with no serious adverse events. Resulted in curative resection and clinical success for mucin-hypersecreting ipnb. Valuable alternative with potential for wider application.
