Percutaneous builiary dilation was done in 3 patients with benign strictures. The first case was 50-year-old male who had multiple intrahepatic stones with biliary stricture. The second 46-year-old female and the third 25-year-old male suffered from recurrent cholangitis with benign stricture of anastomic site after choledochojejunostomy. In the first case, a 6mm diameter Grunzign dilatation balloon catheter was introduced through the T-tube tract. In the sectond case, the stricture was dilated with two balloons of 5mm and 8mm in each diameter sequentially through the U-loop tract formed by surgically made jejunostomy and percutaneous transhepatic puncture. In the third case, the dilatation cather was introduced through the percutaneous transhepatic tract. Dilation was made with a pressure of 5 to 10 atomospher for 1 to 3 minutes duration for 3 times. In all 3 cases , the strictures were successfully dilated and in second and third cases internal stent was left across the lesi n for prevention of restenosis.
