Abstract
A procedure for percutaneous transcystic cholangioscopy requiring only one percutaneous transhepatic fistulous tract to remove stones located in both the gallbladder and bile ducts is described. The procedure begins with percutaneous transhepatic drainage of the gallbladder or bile duct. Stones in the gallbladder and bile duct can be removed under direct vision on transhepatic cholangioscopy. Larger stones can be fragmented by electrohydraulic lithotripsy before removal. In a preliminary trial the procedure proved to be a feasible method for treatment of 13 patients with both gallbladder and bile duct stones as well as septic cholangitis who either refused operation or were considered poor candidates for surgery. On long-term follow-up (mean period 28 months) stone recurrence was observed in three patients.
