A previously healthy 17-year-old male was admitted for pain in the right lower quadrant of the abdomen and emission of blood with stools. Abdominal angio-CT (computed tomography) was negative for active bleeding sources, esophagogastroduodenoscopy showed grade B esophagitis, two colonoscopies could not identify the source of hemorrhage. Bleeding continued during observation; hemoglobin dropped from 13 g/dl at admission at 10 g/dl at 48 h. Capsule endoscopy identified bleeding from the distal ileus.
