INTERNALIZATION OF PTBD CATHETER

PTBD is an invasive and effective therapeutic method of relieving benign or malignant biliary obstruction and may be life saving if the patient is septic.

The drainage is achieved by inserting a plastic tube, called a catheter, through a tiny incision of the skin into the obstructed bile duct.

The cholangiogram performed in the same setting also helps to define the anatomy and identify pathology/abnormality, which are important for planning treatment.

Technical successful rate ranges from 90-95% in dilated system to 70% in non-dilated systems.

Subsequent internalization (either internal/external drainage or internal drainage by stenting on another day, usually days or weeks after the initial PTBD) of the PTBD facilitates internal drainage of bile, which is useful for digestion and therefore reduces the loss of fluid and electrolytes. If the PTBD is entirely internalized by stenting, this may eliminate the inconvenience of carrying an external tube on the abdominal wall.
