Overview
An endoscopic evaluation should be considered if there are persistent symptoms, inconclusive diagnosis, or failure to respond to therapy. Guidelines for the role of endoscopy in the management of patients with diarrhea have been published by the American Society of Gastrointestinal Endoscopy.
Other imaging findings
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.[1]
Colonoscopy
Chronic diarrhea can be diagnosed by colonoscopy with biopsy in patients with IBD, microscopic inflammatory disorders, and colorectal neoplasia.[2]
