Abstract
Management of biliary strictures, previously a total surgical procedure, is now accomplished by percutaneous or endoscopic techniques using biliary drainage catheters, biliary endoprosthesis or balloon catheters. The aim of the work is to study the relative merits of different interventional radiological techniques used in the management of biliary strictures. This study included 65 patients (37 males and 28 females) with biliary strictures (61 malignant and 4 benign) for whom 102 interventional radiological techniques were done including 56 PTDs for 49 patients, 5 internal-external drainage catheters. 17 biliary endoprosthesis (12 plastic and 5 metallic) in 15 patients, 7 percutaneous cholecystostomy, 2 balloon dilatation of benign strictures and 15 endoscopic internal drainage. The patients were categorized according to the type of interventional procedures into 6 groups. In group I (PTD), the mean duration of functioning drainage was 119 days with a dysfunction rate of 22.7% In group II (internal-external), the mean duration of functioning drainage was 119 days with a dysfunction rate of 20%. In group III (biliary endoprosthesis), the mean duration of stent patency was 172.5 and 96 days with dysfunction rates of 33% and 40% for plastic and metallic stents respectively. In group IV (Percutaneous Cholecystostomy), the therapeutic benfits were achieved in all cases. In group V (Balloon dilatation of benign strictures), there was clinical and laboratory improvement in both patients for more than 12 months. In group VI (endoscopic biliary drainage). Proper drainage was achieved in only 25% of patients. We concluded that internal drainage is more efficient in the relief of jaundice and generally improves comfort and general status of the patients. Percutaneous cholecystostomy is a safe and efficient technique. Balloon dilatation is an effective option in the management of benign stricture, and finally that percutaneous techniques have definitive advantages over the endoscopic techniques in patients with high level obstruction.
