Patients with proctitis may have a colonoscopy six months or once a year. Proctitis is a relatively common chronic disease of the digestive system, with a relatively long course, and patients may experience recurrent abdominal pain, diarrhea and bloating. After active treatment and stable control of the disease, colonoscopy can be performed every six months or a year or so to understand the recovery of the intestinal mucosa. Patients with proctitis should not undergo colonoscopy too often, as colonoscopy may damage the intestinal wall and cause aggravation of the condition, and should be rechecked under the guidance of the doctor, or consider rechecking the colonoscopy every two years if the recovery is good at a later stage. Enteroscopy is very necessary for patients with proctitis, but it is also necessary to control the number of inspections, in order to observe the condition at the same time to minimize the damage to the intestinal tract.
