title: Endoscopic therapy for biliary obstruction.
abstract: Endoscopic management of biliary obstruction is feasible in most patients and has emerged as standard treatment. Aside from the removal of bile duct stones, placement of a biliary stent is the most commonly employed modality of management. In experienced hands, this is successful in over 90% of patients. Lower procedure-related complications and the relative non-invasive nature of endoscopic treatment has relegated surgical management to a subsidiary role. Hospitalization time rarely exceeds 1-2 days. In most patients with advanced malignant disease and short life expectancy, stenting affords effective palliation. For the majority of patients endoscopic management is preferable to the percutaneous transhepatic approach due to lower overall mortality and morbidity. Stent occlusion necessitating replacement remains a problem, but improvements in this area can be expected. New plastic stent designs are undergoing investigation. Expandable metallic stents are promising but controlled comparative trials with conventional plastic prostheses are needed. Use of expandable stents should be judicious since these cannot be removed. In the future we can look forward to advances in peroral cholangioscopic technology which may permit targeted treatment of intraductal biliary malignancies.
