| ===Flexible sigmoidoscopy===
| |
| Flexible sigmoidoscopy can be used as an initial diagnostic tool in patients with chronic diarrhea who are pregnant or have significant comorbidities where a colonoscopy is contraindicated. Flexible sigmoidoscopy may however be sufficient in the diagnosis as long as biopsy samples are obtained for histologic evaluation even when the mucosa appears normal to rule out causes of chronic diarrhea such as microscopic colitis.<ref name="pmid20346452">{{cite journal| author=ASGE Standards of Practice Committee.
