Catheters, Biliary, Drainage, Percutaneous, Internal

Definition : Percutaneous drainage biliary catheters that include multiple side holes in the catheter proximal and distal to obstruction, allowing internal drainage of bile through the catheter into the duodenum. Some of these catheters have a pigtail configuration on their distal tip to anchor them to the duodenum and prevent withdrawal. Typically, after successful percutaneous catheterization, external drainage is established (e.g., for 24 hours). Internal drainage is later accomplished by closing the stopcock to the outside so that bile can flow through the internal catheter to the duodenum, bypassing the obstruction.
