Meckel's diverticulum
A particular type of outpouching of the small bowel. It is usually located about 2 feet before the junction of the small bowel with the colon (the large intestine) in the right lower abdomen. About 1 in every 50 people has a Meckel's diverticulum. Meckel's diverticulum can become inflamed, ulcerate, perforate (break open or rupture) and cause obstruction of the small bowel. If it is inflamed or perforated, Meckel's diverticulum is usually removed by surgery.
