Eighteen expandable metallic biliary stents were inserted in patients with malignant (16 patients) or benign (two patients) biliary strictures. Four were the Gianturco‐Rosch biliary Z‐stents and the remaining 14 were the Wallstent. The stents were delivered through either the endoscopic transpapillary (10 patients), percutaneous transhepatic (five patients) or combined percutaneous‐endoscopic (three patients) route. No failure in implantation was encountered. Bile drainage was successful in all patients. Stent occlusions were observed in four patients with hilar obstruction due to tumour overgrowth above the stents at 30–67 days (mean 47.75 days) after insertion. The occlusions were drained percutaneously (two patients) or endoscopically (two patients). Migration of stent did not occur. After a median follow‐up period of 170.5 days (range 57–731 days), 11 patients were still alive and free of jaundice. The median patency period of the stents for common bile duct and hilar obstruction was 288.5 days (range 117–731 days) and 61.5 days (range 30–188 days), respectively. The overall median patency period was 165 days. It is concluded that expandable metallic biliary stent is a useful adjunct to the treatment of malignant biliary obstructions with a better result in distal obstruction.
