Abdominal pain caused by liver cancer requires different treatments according to different causes. Possible causes of abdominal pain include: abdominal pain caused by liver cancer itself, biliary tract infection, abdominal pain caused by ascites, abdominal pain caused by liver cancer itself needs symptomatic pain relief treatment, abdominal pain caused by biliary tract infection needs anti-infection treatment, abdominal pain caused by ascites needs diuretic treatment, abdominal puncture and drainage. 1. Abdominal pain caused by hepatocellular carcinoma itself: patients may have persistent distension and pain in the right upper abdomen, and some of them may have abdominal pain, which can be treated with Tramadol and other analgesic treatments. If the patient’s condition permits, surgical resection of liver cancer as soon as possible will relieve the abdominal pain. 2. Biliary tract infection: If bile duct infection occurs in patients, it will lead to obvious abdominal pain, besides abdominal pain, abdominal distension, accompanied by nausea and vomiting, fever, yellowish muscle thinness, etc. It is necessary to choose sensitive antibiotics for anti-infection treatment, such as cefuroxime and other antibiotics with high concentration in the biliary tract. 3. Ascites: Liver cancer patients may cause a large amount of ascites, which leads to abdominal pain, and can be released by abdominal puncture and treated with diuretic drugs such as furosemide at the same time. Therefore, liver cancer patients with different causes of abdominal pain have different treatments. If the patients have any discomfort, they should go to the hospital for consultation in time, and should not deal with it blindly on their own, so as to avoid delaying the treatment.
