The Clinical Efficacy of Uisng a Soehendra Stent Retriever for Endoscopic Biliary Drainage in Malignant Biliary Obstruction / 대한소화기내시경학회지

ABSTRACT

BACKGROUND/AIMS: Endoscopic biliary drainage is widely used for the palliative treatment of malignant biliary obstruction. For the advanced stricture, the general treatments such as a dilating or balloon catheter can not fully expand a duct. The authors used a Soehendra Stent Retriever for these cases, and we evaluated the value of using this instrument for treating these patients. METHODS: From July 2006 to Jun 2008, we studied 12 patients with mailignant biliary obstruction (Klatskin's tumor=10, Gall bladder cancer=2) and who were failed at having a stent inserted with such general treatment such as using a dilating or balloon catheter (M: F=7:5, age=69.1 years old). For the bilateral biliary drainage of the duct, the "stent in stent" method was used and 12 patients were treated with a Soehendra Stent Retriever with clockwise rotation, as well as going forward to expand the target area of the intrahepatic bile duct obstruction and insert a metal stent. RESULTS: Ten patients among the 12 who were treated by a Soehendra Stent Retriever achieved successful insertion of a stent (technical success, 83.3%), and all 12 patients showed improvement of their jaundice. CONCLUSIONS: To insert bilateral stents for the advanced malignant biliary obstruction, expanding the strictured area with a Soehendra Stent Retriever can improve the success of inserting a stent.
