Answer

Endoscopy is less sensitive for diagnosing C difficile than are stool assays. Endoscopy may demonstrate the presence of raised, yellowish white, 2- to 10-mm plaques overlying an erythematous and edematous mucosa. These plaques are termed pseudomembranes. Endoscopic findings may be normal in patients with mild disease or may demonstrate nonspecific colitis in moderate cases.
