Biliary Endoprosthese by the Use of Expandable Metallic Stents
Abstract
- Expandable metallic stents(EMS) were implanted in 7 patients with malignant (4 cholangio- carcinnoma, 1 pancreatic cancer, 1 ampullary carcinoma and 1 lymph node metastasis) biliary stricutres and 17 patients with benign(13 intrahepatic strictures of primary intrahepatic stone patients, 2 postoperative stricutres, 1 ampullary stenosis followed by endoscopic sphineterotomy and 1 bilioenteric anastomosis) biliary stricutures. In the fifteen patients out of 17 patients with benign biliary stricture, relief of cholangitis, improvement of liver function or loss of pruritus was observed. But in the 2 patients with.biliary cirrhosis, no clinical improvement was noted. In the malignant strictures with cholangio-carcinoma, the occlusion of EMS occurred in 3 patients and the duration of stent patency was average 2 months in those patients.
