Clinically, according to the type of polyps and the time of surgery, there are differences in the types of food that patients can eat after surgery. First, if the patient undergoes endoscopic polypectomy for gastrointestinal polyps, the patient can only eat warm water, rice soup, noodle soup, vegetable soup and other liquid diet within three days after the surgery. After three days, if there is no active bleeding on the surgical wound, the patient can return to semi-liquid diet such as thin porridge, noodles, vegetables, fruits and steamed buns, etc. After one week of surgery, the patient can gradually return to normal diet. Second, if patients undergo laparoscopic surgery to remove gallbladder polyps, the patient’s gastrointestinal function has not yet recovered within 24 hours after surgery, and can only eat a small amount of warm water. 24 hours later, the patient’s anus is exhausted, and can supplement energy by eating thin porridge, noodles, vegetables and other liquid diets. Three days after the operation, the patient’s complete exhaustion and defecation indicate that the patient’s gastrointestinal function has recovered well and can return to a normal diet.
