Histologic Study of Colonic Mucosa in Patients With Chronic Diarrhea and Normal Colonoscopic Findings

Abstract

Histologic lesions of possible diagnostic value could exist in 32.1% of chronic diarrhea patients with normal colonoscopy, which can justify, in certain cases, mucosa biopsies, which might contribute for a more precise etiologic diagnosis; also, the distribution of these histologic changes has pointed out the importance of having all colon segments biopsied.
