Malignant biliary obstruction is commonly due to pancreatic carcinoma, cholangiocarcinoma and metastatic disease which are often inoperable at presentation and carry a poor prognosis. Percutaneous biliary drainage and stenting provides a safe and effective method of palliation in such patients, thereby improving their quality of life. It may also be an adjunct to surgical management by improving hepatic and, indirectly, renal function before resection of the tumor.
