Meckels diverticulum

This lovely out-pouching is Meckels diverticulum!Diverticulum simply means an abnormal pouch or sac formed due to a congenitally weak point along the intestine. Meckel's diverticulum is the most common congenital abnormality of the small intestine; it is caused by an incomplete obliteration of the vitelline duct (ie, omphalomesenteric duct). The duct undergoes progressive narrowing and should disappear by 7 weeks' gestation. When the duct fails to fully obliterate, different types of vitelline duct anomalies appear, such as this true diverticulum, which contains all three layers of the small intestine. The disorder is typically asymptomatic and clinically presents with painless rectal bleeding. Definitive treatment of complications, such as a bleeding diverticulum, perforation, and obstruction, is a surgical excision of the diverticulum along with the adjacent ileal segment, which may be ulcerated. This can be accomplished through laparoscopy or open surgery.
