Midgut herniation occurs due to which reason?

Midgut herniation occurs due to which reason?

• A. The midgut grows rapidly and there is not enough room in the abdomen
• B. The liver expands into the abdomen forcing it out
• C. The stomach pushes the midgut
• D. The spleen withdraws the midgut

Answer: (A)

Midgut herniation happens because the midgut elongates rapidly while the abdominal cavity is still relatively small. This mismatch in growth creates a temporary space that isn’t enough to hold the looping intestine, so the gut herniates into the umbilical cord. It’s a normal, temporary stage called physiological herniation, and the intestines eventually return to the abdomen as the cavity grows and the gut completes its rotation (about 270 degrees counterclockwise) around the artery of the midgut, typically by week 10. It isn’t caused by the liver expanding, the stomach pushing the midgut, or the spleen pulling it back; those ideas don’t explain the necessary space and timing for this process.
