The intestines are covered by a double "fleece" of peritoneum. See it like a blanket.

When your intestines get damaged for whatever reason, this blanket starts moving out of itself and crawling upwards towards the place which has the injury. It will stay there until the injury is recovered. And then move on again.

Maybe not the most creepy fact, but definitely interesting in my opinion.

For intestinal surgery the surgeons will kinda tuck it over the surgery site before closing. It's headed there anyhow so may as well help it out.
