Abstract:
Percutaneous transhepatic cholangioscopy (PTCS) is the most widely used modality for diagnosis and treatment of biliary disease. Although many other novel technologies have been developed based on recent advances in endoscopy, PTCS has its own role. In diagnostics, PTCS is used for evaluation of indeterminate biliary strictures, bile duct tumors, and postoperative biliary strictures that cannot be reached by a peroral approach. In therapeutics, the removal of bile duct stones, dilatation of bile duct strictures including postoperative anastomosis site strictures, and local tumor therapy are indications of PTCS. Especially in a therapeutic role, PTCS has the advantage of maneuverability due to a shorter endoscopic length compared to other cholangioscopic modalities. Hence, PTCS has its own indispensable diagnostic and therapeutic roles.
