T-tubes after choledochal stone surgery need to be removed when there are no bile duct stones or bile duct stenosis after undergoing an examination, and the removal needs to be done under a doctor’s supervision.
The T-tube is commonly used to support and drain the bile duct after choledochal stone surgery, which can drain bile directly out of the body and have a decompression effect on the bile duct.The T-tube can also facilitate the doctor to remove the stone directly from the sinus opening formed by the T-tube when there are residual choledocholithiasis, avoiding the risk of re-surgery.
The T-tube is usually removed about 30 days after surgery for choledocholithiasis. Before removal, the T-tube needs to be examined to make sure that there are no bile duct stones or bile duct stenosis, the T-tube is clamped shut, and the T-tube can be removed directly when there are no subsequent symptoms such as fever or abdominal pain.
After removing the T-tube, the patient’s vital signs need to be closely monitored, and any discomfort should be seen as soon as possible.
