When patients with advanced liver cancer cannot eat normally, we should first look at the cause of the patient’s inability to eat, whether it is caused by tumor metastasis to the stomach causing obstruction in the digestive tract or due to other reasons. The patient should have further relevant examination, such as CT scan or nuclear magnetic examination of the whole abdomen, to determine the site of obstruction and the possible causes of obstruction. If the obstruction is due to gastrointestinal obstruction, a jejunal tube can be placed under gastroscopy or radiation if necessary. Once the jejunal tube is in place, enteral nutrition can be administered via the jejunal tube. If the patient is considered to have gastrointestinal obstruction, laparoscopic or open gastrointestinal short-circuit surgery, or fistula surgery, may also be considered. Nutritional tubes are placed through the fistula opening, and enteral nutrition is administered via the nutritional tube for a period of time. The patient should be careful to eat less fatty foods and a high protein diet, as fatty foods and a high protein diet may induce hepatic encephalopathy in the patient.
