Infant with abdominal pain and currant jelly stools and peritonitis

AXR of small bowel obstruction due to intussusception
AXR supine (left) shows decompressed loops of bowel (presumed jejunum) in the left upper quadrant and multiple dilated loops of bowel (presumed ileum) in the right lower quadrant. AXR upright (right) shows multiple air-fluid levels.

The diagnosis was distal small bowel obstruction with the patient going directly to the operating room due to the peritonitis where an ileocolic intussusception was encountered and reduced.
