Abstract
Electrohydraulic lithotripsy (EHL) is a method used to breakup the stone by electric discharge in the presence of liquid medium. Recently we experienced a case of successful common bile duct stone removal after EHL during choledochoscopy via T-tube tract, which was the first case of EHL in biliary tract stone in Korea. A 65-year-old female patient was admitted to our hospital because of generalized pruritus after cholcystectomy with T-tube insertion. Obtained cholangiogram showed retained CBD stone which was implssible to remove by Dormian basket and tto dissolute by monooctanoin. After only one session of EHL, we can disintergrat CBD stone into several small pieces and removal of stone was easily done by Basket. After Small cut endoscopic sphincterotomy (EST) remained distal impacted stone was freely passed and control choledochoscopy and cholangiogram showed no remained stone. We think that EHL may be play a potential role in removal of biliary tract stones as in urinary tract stones.
