Other Diagnostic Studies
- In young patients with symptoms of classic IBS, additional invasive investigations such as endoscopy are not required and increase patient dissatisfaction.[1]
- Gastrointestinal endoscopy is done in difficult cases of IBS where history is unclear but the physical examination is suggestive of the diagnosis.
- All IBS patients with alarm features must undergo endoscopic evaluation.
- Colonoscopy must be considered in patients aged more than 50 years as part of routine colon cancer screening.
- In IBS patients with persistent diarrhea of age >40 years, a colonoscopy should also be performed to rule out organic causes like IBD and perform biopsies.
- IBS patients with dyspepsia should undergo esophagogastroduodenoscopy.
- Sigmoidoscopy is performed in patients in order to exclude melanosis coli due to laxative abuse and microinflammation.
- Sigmoid colon biopsies and duodenal biopsies are required for exclusion of microscopic colitis, Crohn's disease, and celiac disease.
Anorectal manometry
Anorectal manometry rules out obstructive defecation (pelvic-floor dyssynergia).
