The removal time of the bile drainage tube should be determined according to the disease, that is, the reason for the catheter placement. The first case is bile duct stones. Obstructive jaundice caused by bile duct stones requires catheterization. In the second case, the malignant tumor of the biliary tract causes obstruction, and extubation should be performed according to the surgical situation. If it is determined that the catheter cannot be extubated without surgery, the catheter needs to be placed all the time, otherwise the jaundice will be aggravated, and it may also cause rapid abnormal liver function. In the third case, if the catheter is placed due to gallbladder suppuration, the catheter needs to be placed for drainage and anti-inflammation. The catheter can be extubated until the inflammation is controlled and the clinical symptoms are relieved.
