Abstract
We evaluated the efficacy of wide 14F endoprostheses endoscopically placed in en patients with malignant extrahepatic bile duct stenosis. Large-bore stents were successfully placed in all patients. There were no early complications. Stent clogging occurred in two patients after one month and after three months in another patient. Seven patients remained free of symptoms after a mean follow-up period of 4.5 months.
