A 13-month-old child is brought to the emergency department after his parents found blood in his stool. They state that he did not appear distressed at the time, although he now displays some tenderness to abdominal pressure. Other than this tenderness, there are no signifi cant findings on physical examination. After performing radionuclide imaging using 99mTc pertechnetate, the doctor makes a diagnosis and recommends surgery to correct the problem. What is the probable source of this child’s condition?
(A) Blockage of the intestine due to folding of the distal ileum into the proximal colon
(B) Breakdown of the stomach mucosal barrier with erosion of the underlying mucosa
