Bile leakage from the T-tube wound may be due to loose suture of the T-tube, or it may be due to the obstruction of the bile duct, which leads to excessive bile leakage.T-tube refers to T-tube for abdominal drainage, which is used to drain bile after biliary surgery, and it is common for biliary stones to reduce the pressure of bile ducts. 1. Loose suture: During T-tube drainage, a small incision will be made in the skin, and when the T-tube is placed, 1-2 stitches will be needed to fix it. In the later recovery process, the suture may be slipped or loosened, which will lead to the loosening of the T-tube, and the bile will flow out of the body along the loosened T-tube. 2. Biliary tract obstruction: for patients with biliary tract stones or biliary tract tumors, when the stones or tumors are severely obstructed, the bile ducts are very narrow, which leads to the bile not easily flowing through the bile ducts, and it will be silted up in the gallbladder and bile ducts, and when it is more than the ability of T-tube to drain, it will flow out of the wounds, and bile will also ooze out of the wounds at this time. When bile is found oozing from the T-tube wound, it is important to find a doctor to deal with it in time to avoid unnecessary troubles such as infection.
