Under what circumstances should colonoscopy be done?

Patients with chronic abdominal pain, diarrhea, and unexplained hematochezia and abdominal mass need to undergo colonoscopy.

Secondly, if the above symptoms do not improve significantly after conventional drug treatment, colonoscopy is also required. Some diseases, such as Crohn's disease and amoebic enteropathy, need to be followed up and observed. In addition, if there is bleeding, foreign bodies, intestinal polyps, etc. in the intestinal tract, colonoscopy can be used for endoscopic treatment
