Results of the placement of multiple endoscopic stents for postoperative biliary strictures remains excellent after long-term follow-up
Date:9/21/2010

OAK BROOK, Ill. September 21, 2010 Researchers from Italy have reported results from more than 10 years of follow-up showing that the placement of multiple endoscopic stents for the treatment of postoperative biliary strictures remains excellent with a low rate of stricture recurrence after this lengthy period of time. When strictures do recur, they can be safely and successfully retreated endoscopically. The study appears in the September issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE).

Most patients with biliary strictures, also called bile duct stricture, remain asymptomatic until the lumen of the bile duct is narrowed to cause resistance to the flow of bile. Bile is a fluid secreted by the liver via the bile ducts and is concentrated in the gallbladder before moving into the intestines. With the advent of laparoscopic cholecystectomy (gallbladder removal), the incidence of bile duct injuries has increased significantly. There are approximately 750,000 cholecystectomies performed in the United States each year. Although biliary strictures may be asymptomatic, if ignored, they can cause life-threatening complications. While strictures of the bile duct can be benign or malignant, approximately 80 percent of benign strictures occur following injury during a cholecystectomy.

Three kinds of treatment for biliary strictures are available: surgical, endoscopic and percutaneous. In 2001, a method for endoscopic management of postoperative biliary strictures was reported that included the placement of multiple stents until stricture resolution. A stent is a short narrow metal or plastic tube in mesh form that is inserted into the lumen of an anatomical vessel (such as an artery or bile duct) to keep a previously blocked passageway open. The initial results of this method were very promising, with a mean patient follow-up of four years. '/>"/>
