Bile duct stenting surgery first requires a judgment of the patient’s physical condition and a preoperative examination. During the procedure, a stent is placed into the bile duct under the guidance of ultrasound or CT to dilate and drain the bile duct. Bile duct stenting is generally used for bile duct stenosis caused by stones, infections and other conditions. For patients undergoing bile duct stenting, preoperative tests such as cardiopulmonary function tests, blood tests, and liver and kidney functions are required, and if there are no obvious contraindications to the surgery, the next step of the treatment plan can be formulated. Bile duct stenting surgery requires imaging tests such as ultrasound and CT to determine the part of the surgery and where the stent will be placed. After the above operation, the doctor can percutaneously puncture the bile duct through the liver and put the dilatation tube into the bile duct stenting operation, and then conduct imaging examination again to determine whether the position is correct, etc. After the bile duct stenting operation, the patient can have the bile duct stented and the bile duct stented. After the operation, the patient’s symptoms should also be closely observed, such as the color of the drainage and the amount of drainage. Regarding the specific operation procedures of biliary stent surgery, there will be some variability depending on the region as well as the condition, so it is recommended to consult a specialized doctor.
