Pediatric Abdominal Imaging — Flashcards

Flashcard 3: What is the next best investigation for a patient with suspected jejunal atresia on X-ray?

Answer: Upper GI contrast study (Upper GI series)

Extra: In neonates with suspected proximal intestinal obstruction (such as jejunal atresia) where the X-ray is not diagnostic, an Upper GI series is the next step to confirm the level of obstruction and, crucially, to rule out malrotation with midgut volvulus. Note: For distal bowel obstruction (multiple dilated loops on X-ray), a contrast enema is typically the next investigation of choice to differentiate between ileal atresia, meconium ileus, and Hirschsprung's disease.
