Percutaneous Biliary Interventions

Biliary drainage is important in the care of patients with benign and malignant biliary obstruction. Careful preprocedure evaluation of high-quality cross-sectional imaging and inventory of symptoms are necessary to determine whether a percutaneous, endoscopic, or surgical approach is most appropriate. High bile duct obstruction is usually best managed percutaneously; a specific duct can be targeted and enteric contamination of isolated ducts can be avoided. Options for percutaneous biliary intervention include external or internal/external biliary drainage, stent placement, biliary stone retrieval, and bile duct biopsy. Preprocedure evaluation, technique, and indications for percutaneous intervention in benign and malignant diseases are summarized.
