Abstract
The removal of choledocholithiasis using percutaneous transhepatic cholangioscopy (PTCS) was performed in 10 cases with large choledocholithiasis. Endoscopic sphincter-otomy (EST) was failed to remove the stones in 8 cases, and 2 cases wer impossible to perform EST. The stones were destructed with electrohydrauric lithotriptor (EHL) and pushed outto duodenum or removed with basket catheter under jejunoscope. The success rate to remove the stones was 100 %. The average frequency of treatment with EHL was 3.2 ± 2.7 times, that of the basket catheter treatment with jejunoscope was 1.3 ± 2.0 times, and average period of admission was 74±30 occured in 3 cases, cholangitis, congestive heart failure and bleeding while making the tract for PTCS. Inflammatory stenosis of the bile duct occured in one dead case as a late complication. Our results indicate that EHL under PTCS is useful to remove these stones.
