Kehr's T tube : a tube consisting of a stem and a cross head (thus shaped like a T). The cross head is placed into the common bile duct while the stem is connected to a small pouch (i.e. bile bag). It is used as a temporary post-operative drainage of common bile duct.


Hans Kehr (1862-1916), a German surgeon, is known for the development of surgical procedures for the treatment of bile duct and gall bladder diseases. One of his contributions in medicine is the T tube. It is a temporary device used to drain the bile, especially after hepatic surgery or liver transplant.
