Percutaneous biliary drainage with the Biliary Stent is utilized for the management of both benign and malignant biliary obstruction. The stent is used to prevent or relieve sepsis, to relieve symptoms of obstruction such as pruritis, and to maintain a pathway for bile flow into the bowel for digestive function.

The stent is indicated for malignant biliary obstruction, such as primary bile duct or biliary tract carcinoma, pancreatic carcinoma, metastases to the porta hepatis, and other malignant conditions causing obstructive jaundice.

The stent can also be used in cases of benign biliary obstruction such as strictures secondary to primary or iatrogenic trauma pancreatitis, biliary calculi, or biliary leaks.
