Zhao Wensheng asked: "An emergency patient suddenly sent here has been preliminarily diagnosed with abdominal trauma and massive internal bleeding. After completing an abdominal CT scan, the patient is immediately sent to the operating room for hemostasis. Upon opening the abdominal cavity, it is found that there are varying degrees of damage to the liver, bile ducts, and intestines. After completing the hemostasis and repair work, while preparing to place a drainage tube, it is found once again that the patient's bile ducts are naturally narrower than normal, and the current drainage tubes available do not fit the size. What should be done at this time?"
What to do?
