A case of unexpected regeneration of small intestinal mucosal necrosis.

If full-thickness mucosa, including the mucosal crypt, has been almost denuded, mucosa cannot regenerate as has been shown by animal models. The authors experienced an unusual mucosal regeneration exceed denuded bowel that occur in midgut volvulus of duration 2 days in a 6-day-old infant. Santulli's jejunostomy was performed using seriously denuded small bowel to prevent short bowel syndrome, despite the risks of leakage or stricture. Subsequently, stomal mucosa was fully regenerated when grossly identified 19 days after the second operation without any surgical complications.
