T-tube (Kehr tube)
Rubber or silicone tube shaped like the letter T: the short crossbar sits inside the bile duct while the long limb exits through the skin.
How it is used
Temporary drainage of the common bile duct after choledochotomy (removal of common bile duct stones), leaving an access route for postoperative cholangiography.
Clinical tip
Before removal, a check cholangiogram can be performed through it, injecting contrast to confirm the bile duct is patent.
