Percutaneous biliary interventions in the treatment of obstruction of the bile ducts of tumor etiology: current trends

Abstract

Palliative endobiliary interventions for malignant obstruction of the biliary tract at the planning stage require a multidisciplinary approach with mandatory consideration of all the anatomical features of the block and clinical manifestations of the pathology. Transhepatic stenting requires differentiated use of both the design features of biliary stents and the technology of their implantation and positioning. This article discusses the promise of intraductal ablation, brachytherapy, photodynamic therapy, and external beam radiation, which can prolong biliary stent patency and minimize the need for repeated intervention.
