A prospective, multicenter study of a double stent system for palliative treatment of malignant extrahepatic biliary obstructions

Abstract

Percutaneous treatment of malignant extrahepatic biliary obstruction using a double stent safely and effectively achieves internal biliary drainage.

Acute pancreatitis after percutaneous insertion of metallic biliary stents in patients with unresectable pancreatic cancer

“…3,8,10,13,25,31 Similarly, the overall survival time of 150 days seen in the current study was similar to the 132e394 days reported previously. 3,8,10,13,31 The study has some inherent limitations. First, data collection was performed retrospectively and this may affect the reliability of the evaluation.…”

“…These findings are in accordance with the results of previous studies, which showed a technical success rate of 99.4e100%, an overall complication rate of 6.9e23.4%, and a successful internal drainage rate of 79.7e100%. 3,8,10,13,25,31 In addition, we saw a median stent patency duration of 117 days, which is similar to previous reports of 114e317 days. 3,8,10,13,25,31 Similarly, the overall survival time of 150 days seen in the current study was similar to the 132e394 days reported previously.…”

Malignant Hilar Biliary Obstruction: Treatment by Means of Placement of a Newly Designed Y-Shaped Branched Covered Stent

“…Various methods of preventing stent migration have been described [10,11,26]. In our study, no stent migration occurred, and we assume that our partially covered stent design with both bare ends (CBD section and long limb of the main piece, and contralateral limb) may resist migration of the stent.…”

Double-Stent System with Long Duodenal Extension for Palliative Treatment of Malignant Extrahepatic Biliary Obstructions: A Prospective Study

“…The use of covered stents in the biliary system was initially developed to address the issue of tumor ingrowth. A variety of covering materials have been manufactured and tested to prevent tumor ingrowth and to avoid the need for re-intervention ( 5 6 7 8 9 10 11 12 13 14 15 ). In last 12 years, polytetrafluoroethylene (PTFE)-covered stents have been demonstrated as an effective treatment method ( 9 10 11 12 13 14 15 ), with the PTFE material serving as an effective barrier to prevent tumor ingrowth.…”
