Recovery time after a painless gastroenteroscopy and removal of polyps varies depending on the type of polyp procedure. Small polyps, 2 to 3 days recovery, large polyps, about a week. Painless gastroscopy, which involves going in under anesthesia to look at the esophagus and stomach, and colonoscopy, which is an examination to look at the rectum, colon, appendix opening, and the end of the ileum, are generally quicker to recover, with recovery in 1 to 2 days. After polyps are found and removed during gastroenteroscopy, the recovery time is prolonged depending on the size of the polyp and other circumstances. For example, for polyps smaller than 5mm, the procedure is less invasive and the recovery period is 2 to 3 days. For polyps smaller than 1cm, the trauma is large and the recovery period may be around 3 to 5 days. Polyps larger than 1cm usually require metal clips to close the incision, and the recovery period takes about 7 days. You should eat strictly as prescribed after a painless gastroenteroscopy and polypectomy.
