Colonoscopic features of eosinophilic gastroenteritis.

This report describes the colonoscopic findings in a patient with eosinophilic gastroenteritis and the effect of treatment upon the course of the disease. Clinical manifestations and treatment depend upon the site of bowel involvement. The patient had mucosal involvement of stomach and small intestine, but colonoscopy demonstrated extensive colorectal involvment, most severe distally. We suggest fiberoptic sigmoidoscopy as an alternative diagnostic modality.
