The following is a case of bleeding intestinal duplication detected preoperatively with technetium-99m sodium pertechnetate. CASE REPORT A 6-year-old male child presented with melena starting two days prior to admission. On the day of admission the patient complained of intermittent epigastric pain. The patient had a past history of one episode of rectal bleeding at age 18 months. Physical examination on admission revealed a heart rate of 132/rain, respiratory rate of 24/min, blood pressure 94/50, and extreme pallor. He was unable to hold himself erect. His abdominal exam was unremarkable with exception of increased bowel sounds. Rectal examination was normal, and the stool was melanotic. Nasogastric aspiration was negative for blood. Chest x-ray and flat plate of the abdomen were normal. Admission laboratory examination revealed: WBC 13,700, hemoglobin 5.6 g/100 ml, hematocrit 15.9%, MCV 85/xm 3, reticulocytes 4.9%. Barium swallow and upper-gastrointestinal series were normal. Small-bowel follow-through revealed a mucosal abnormality with trapping of barium between three large folds (Figure 1) in the right lower quadrant. Barium enema was normal. Technetium scan of the abdomen was performed, and it revealed a consistent large area of increased uptake in the right lower quadrant (Figure 2). The patient was taken to surgery, and an intestinal duplication was found in the mesentery, 3 ft from the ileocecal valve.
