This study was conducted to examine the usefulness of endoscopic transpapillary procedure in post-cholecystectomy bile duct stricture and postcholecystectomy bile leakage. Endoscopic transpapillary procedure was performed in 18 cases of post-cholecystectomy bile duct stricture and 6 cases of @entity9834 . In the bile duct stricture cases, the @entity1 were assessed for the stricture by endoscopic retrograde cholangiography (ERC), and then underwent endoscopic sphincterotomy (EST) for tube stent insertion. The stents was replaced every 3 to 6 months, and the treatment was continued until the @entity1 became stent-free. Successful therapy was defined as a stent-free condition without @entity99 . In the bile leakage cases, the leakage was located by ERC and EST was performed. Then, endoscopic nasobiliary drainage (ENBD) tube was inserted at the proximal side of the bile leakage, and the therapeutic outcome was defined as successful if disappearance of the leakage was confirmed by cholangiography at a later date. Endoscopic transpapillary procedure was 100% successful in both post-cholecystectomy bile duct stricture cases (18/18) and @entity9834 cases (6/6). There was no accident due to the treatment. Restricture occurred in 5.5% (1/18) of the @entity1 , but additional therapy was successful and the stent was removed. Also, there was no accident due to endoscopic transpapillary procedure. Endoscopic transpapillary procedure in postcholecystectomy bile duct stricture and postcholecystectomy bile leakage was demonstrated to be a less invasive, safe, and useful method.
