The risk of bile duct cancer surgery is relatively high. Because at present, traditional surgery is mainly chosen for bile duct cancer surgery, which is more traumatic and requires more organs and tissues to be removed (including pancreatic head, duodenum, part of stomach, bile duct, gallbladder, etc.), and there are gastrointestinal, pancreatic-intestinal and biliary-intestinal anastomoses after surgery. This surgery is easy to bleed after surgery, and if relevant care is not done properly, it is easy to cause secondary infection, resulting in redness, swelling, pain, pus, and in serious cases, fluid may ooze out from the wound. Cholangiocarcinoma surgery is prone to related complications and sequelae, such as the formation of fistula after surgery, or the decline of liver function, which prevents the liver from metabolizing normally; after choledochotomy surgery, the condition of some patients may recur again, so cholangiocarcinoma surgery is more risky. If cholangiocarcinoma is detected and needs surgery, it is recommended to consult a doctor in time and analyze whether the conditions of surgery are met and whether there are contraindications to surgery under the guidance of a professional doctor, and then choose the best treatment according to one’s own situation.
