BALLOONPLASTY FOR BILIARY STRICTURES ASSOCIATED WITH CHOLEDOCHAL CYSTS

Balloonplasty with a Meditec balloon dilatation catheter was performed in thirteen patients who had choledochal cysts with intrahepatic biliary strictures. The age of the patients ranged from one to 28 years. Eleven were female, and two were male. The site of the biliary stricture was both the right and left hepatic duct in eight patients, the left hepatic duct in four, and the right hepatic duct in one. Balloonplasty was performed postoperatively through the fistula of the percutaneous transhepatic drainage tube in seven patients and during the operation in six.
Dilatation was adequate in ten patients but insufficient in three. The preoperative imaging character of the biliary strictures in the successful cases was membranous stenosis of less than 2mm in length. In contrast, the strictures of the patients with insufficient dilatation were long stenoses of more than 5mm in length.
