What is the purpose of a t tube and describe stab wound placement of the drain?

A T tube is used primarily to facilitate bile drainage from the common bile duct after surgery or in cases of obstruction, allowing for the assessment of bile flow and preventing complications such as bile leaks. The drain is typically placed through a stab wound in the skin, positioned in the right upper quadrant, where the tube is inserted into the bile duct. This placement ensures effective drainage while minimizing trauma to surrounding tissues. Proper positioning and care of the T tube are crucial for optimal recovery and function.
