Definition of Diverticulum, Meckel's
Medically reviewed by Dr. Otari Nergadze, Neurosurgeon | Updated: January 2026
Diverticulum, Meckel's: An outpouching of the small bowel. About 1 in every 50 (2%) people has a Meckel's diverticulum. It is usually 2 inches long and is located about 2 feet before the junction of the small bowel with the colon (the large intestine) in the right lower abdomen.
Meckel's diverticulum can become inflamed, ulcerate and perforate (break open or rupture). This can cause obstruction of the small bowel. Ulceration of a Meckel can cause lower intestinal bleeding.
If it is inflamed or perforated, Meckel's diverticulum is usually removed by surgery.
