The liver can be removed when significant lesions are found in the liver and can be removed after conservative treatment and medication have failed. If bile duct stones are found in the liver, causing the patient to have fever and jaundice, a partial resection of the liver can be done. After the operation, the diet can then be controlled, such as trying not to drink drinks containing alcohol, not to eat overly oily food, to consume fresh fruits and green vegetables, and to consume low-fat high-quality protein appropriately. If malignant tumors are found in the liver, radical resection of malignant tumors can be performed. After surgery, depending on the pathological results, chemotherapy, targeted drug therapy, herbal medicine, etc. may need to be given and the disease may be cured. Even if the disease is severe, it can prolong the life of the patient and improve the quality of survival. However, the liver cannot be excised too much, otherwise it will lead to liver failure and thus endanger life. The exact extent of excision can be consulted with the competent physician.
