Percutaneous-Endoscopic Biliary Stent Placement

Abstract

The placement of large-bore endoprostheses for relief of biliary obstruction by the percutaneous-transhepatic route is painful, requires a large hepatic parenchymal tract, and has a fairly high complication rate. The alternative technique of endoscopically placing similar-sized stents requires special instruments and skills, and may fail in passing very tight stenoses. We report a simpler combined percutaneous-endoscopic biliary stent (PEBS) placement technique with a high placement rate used in 11 patients with advanced malignant obstruction. In all 11 patients, 10 and 11.5 French stents were easily placed. Three patients developed sepsis but responded to antibiotics. One clogged stent required replacement. Two stents needed later endoscopic adjustment. Results of liver function test improved in 10 patients, and 8 patients showed improved quality of life.
