Patients with liver cancer should fast and abstain from water and eating anything for the first 2 days after surgery, and they should be treated through intravenous infusion and enteral nutrition, which requires large amount of supplemental albumin. When the gastrointestinal tract function recovers around 3 days after surgery and the anus has exhausted and defecated, the patient can resume the diet, starting from liquid food, semi-liquid food, such as drinking thin rice, rice soup, eating noodles, soup food such as fish soup, rib soup, etc. It is recommended to make it light and not too much fat content. The patient’s gastrointestinal function will be affected after surgery, and too much fat will cause stomach discomfort or lead to diarrhea, etc. The patient will recover in about a week after surgery and can gradually transition to a normal diet and eat fresh vegetables and fruits.
