T-Drainage Tube, also known as T-tube, is a medical device used to drain bile and other fluids from the common bile duct or liver. It is typically used after surgery to the gallbladder or liver to prevent the buildup of fluids or bile.

 

The T-tube consists of a long, narrow tube that is inserted into the common bile duct or liver through a small incision in the abdomen. The tube is then secured in place with a stitch or clip, and the other end of the tube is left outside the body. The T-tube has a "T" shape, with one end of the "T" being the long tube inserted into the body and the other end of the "T" being a shorter tube that is attached to a collection bag.

 

The T-tube allows bile and other fluids to drain out of the body and into the collection bag, which can then be monitored by healthcare professionals to ensure that the drainage is functioning properly. The T-tube is typically left in place for several days to several weeks, depending on the patient's condition and the amount of fluid being drained.
