The number of days of hospitalization for excision of intestinal polyps depends on the size and number of polyps and the surgical method, etc. Some patients do not need to be hospitalized and some patients need to be hospitalized for 3-5 days. If the patient has only a single polyp and it is small, and there are no other underlying diseases, the polyp can be removed by colonoscopy in an outpatient clinic, and the patient can be observed for 1-2 hours after the procedure, and can be discharged with drugs for intestinal nutrition and intestinal flora regulation without hospitalization. If the polyp is large or accompanied by other underlying diseases, the patient needs to be hospitalized for a comprehensive examination and evaluation before surgery, and the patient has to be observed for 1-2 days after surgery, and can be discharged in 3-5 days after a smooth recovery. If the polyp is more serious, open surgery is required and the recovery time is relatively long, usually requiring hospitalization for about 1 week. If the patient’s pathological examination results show malignant tumor, further surgery will be required and the hospital stay will be extended. Patients are advised to pay attention to a reasonable diet after intestinal polyp surgery and avoid alcohol and spicy stimulating foods to promote early recovery.
