Patients after minimally invasive surgery should try to eat easy-to-digest, warm and cool foods, such as thin rice, rice soup, fish soup, rib soup and steamed eggs. Because these foods are rich in nutrients, they can provide water without aggravating the burden of gastrointestinal function. There are many types of minimally invasive surgeries, the common ones are laparoscopic minimally invasive surgeries, including laparoscopic cholecystectomy, laparoscopic appendectomy, laparoscopic radical treatment of gastric cancer, laparoscopic radical treatment of colorectal cancer and so on. After the surgery, the recovery of gastrointestinal function will be affected to a greater or lesser extent. In the short term, patients may have abdominal distension, nausea and other discomforts, and they can eat fluids or semi-fluids after passing gas and defecation, and they can go back to normal diet after their condition has completely recovered in the later stage.
