PERCUTANEOUS TRANSHEPATIC BALLOON DILATION FOR PAPILLARY STENOSIS

In this study, a case of primary common bile duct stone due to papilla ry stenosis is reported. The patient was a 68-year-old man with compla ints of epigastric pain and fever who had undergone gastrectomy at age 55 and cholecystectomy with choledocholithotomy at age 62. Laboratory data revealed elevation of the transaminases acid biliary enzymes. Bo th abdominal ultrasonography and CT scan revealed dilatation of the co mmon. bile duct with stones. Since endoscopic retrograde cholangiopanc reatography could not visualize the bile duct, percutaneous transhepat ic biliary drainage was carried out. After lithotripsy by percutaneous transhepatic cholangioscopy a diagnosis of papillary stenosis was mad e following percutaneous transhepatic manometry of the sphincter of Od di, and balloon. dilatation. through the PTBD fistula was successfully performed. In this case report, emphasis is placed on the diagnosis a nd treatment of papillary stenosis.
