Fiberoptic endoscopy of the gastrointestinal tract in infants and children. II. Fiberoptic colonoscopy and polypectomy in 15 children.

Fiberoptic colonoscopy was performed on 15 patients between the ages of 1 1/2 years and 16 years. Ten patients were hospitalized and five were outpatients. Of 12 with frank or microscopic blood in stools, fiberoptic colonoscopy revealed single polyps in six patients, ulcerative colitis in two and negative results in four with prior nondiagnostic radiographic studies, colonoscopy revealed ulcerative colitis in one, granulomatous colitis in one and negative findings in one. Polypectomy through the colonoscope was accomplished in all six patients with polyps. Perforation of the sigmoid colon during polypectomy with the snare loop was the single complication encountered. Lower intestinal endoscopy should be selectively considered for diagnosis and therapy of unexplained bleeding or recurrent lower abdominal pain in children in whom proctosigmoidoscopic laboratory and radiographic examinations do not achieve a diagnosis.
