Abstract
We report two pediatric patients with Meckel diverticulum diagnosed by double-balloon enteroscopy (DBE). Case 1 was an 8-year-old boy with congenital heart disease complained of general fatigue and tarry stools. His hemoglobin level was 4.5 g/dl. Although Tc 99m-labeled red blood cell scintigraphy showed active bleeding around the ileocecal area, upper and lower ileocecal endoscopy could not detect the source of bleeding. Negative results were obtained with Tc-99m pertechnetate scintigraphy. Case 2 was a 12-year-old boy presented with massive tarry stools and required blood transfusion. Findings of Tc-99m pertechnetate scintigraphy were negative. These two patients were diagnosed with Meckel diverticulum by DBE. Meckel diverticles were subsequently resected through small incisions. DBE is feasible for the diagnosis of pediatric small-bowel bleeding of unknown origin, and accurate diagnosis of Meckel diverticulum can provide adequate treatment.
