Hepatoportal cholangiocarcinoma causes great difficulties in surgical resection due to its special location, infiltrative growth and close relationship with hepatoportal blood vessels, so what are the complications after surgery? Common postoperative complications 1. Biliary fistula: it is mostly related to the patient’s personal physical condition, nutritional status and the decrease of self-repairing ability of the body, and usually occurs 5-7 days after surgery. 2, bleeding: including anastomotic bleeding and abdominal bleeding. 3, liver failure: that is, the remaining liver is unable to compensate after surgery. If the jaundice is very deep and the volume of the removed liver is large, the risk of liver failure will be relatively high. 4.Gastroparesis: Some patients will have poor gastric power, vomiting and inability to eat after surgery. 5, abdominal infection: patients with abdominal infection are mostly related to biliary fistula and abdominal bleeding. To reduce complications, preoperative evaluation is important There are relatively more complications common to hepatobiliary and pancreatic surgery, and it will be more difficult to avoid them completely. Like biliary fistula and bleeding, the surgeon has some prevention effect by refining the surgery as much as possible intraoperatively. To avoid liver failure, the function of the patient’s remaining liver needs to be assessed preoperatively. If the volume of the remaining liver is not sufficient postoperatively, then liver failure is likely to occur and adequate preoperative yellowing reduction and preoperative portal vein embolization should be done. In addition, any patient who has undergone intra-abdominal surgery has a change in the normal intra-abdominal anatomy and is more or less likely to have adhesions. Therefore, any re-operation will be more difficult, and the preoperative evaluation should be more accurate and better prepared. Doctor’s tip: It is crucial to staging hilar cholangiocarcinoma before surgery, not only to make a comprehensive resectability assessment of hilar cholangiocarcinoma, but also to predict the patient’s prognosis and reduce complications by the pathological type of tumor and the volume of the remaining liver after surgery. In the early postoperative period, we should pay attention to the prevention and treatment of complications, keep all kinds of drainage ducts unobstructed and do not slip, encourage patients to get up and move early to prevent crushing pneumonia, and seek medical treatment promptly in case of discomfort or corresponding complications; in the distant period, we should insist on regular follow-up to prevent recurrence.
