Summary

A Meckel's diverticulum is a malformation of the gastrointestinal system, characterized by a small pouch that forms on the wall of the distal ileal part of the small intestine. It occurs when during fetal development, part of the intestine fails to close up properly.

Meckel's diverticulum can cause problems if food or other material becomes trapped in the pouch, leading to bowel infection or even perforation. Surgery is usually needed to remove a Meckel diverticulum.
