Meckel’s diverticulum

Congenital intestinal protrusion, more common in men than women. It consists of a remaining fragment of the connection between the navel and intestine. The protrusion occurs on the final section of the small intestine, before the junction with the colon. The condition is usually unnoticed, and generally causes no discomfort. If there is discomfort it is probably the result of strands connected to the diverticulum: tangling, ileus, intestinal volvulus, or intussusception. Discomfort can also be caused by the presence of gastric mucous membrane in the diverticulum, which can be affected by a stomach ulcer. Symptoms of stomach ulcer around the navel which do not react to antacids or the consumption of food can indicate ulcer formation in the diverticulum. If Meckel’s diverticulum is causing problems of this kind, it can be removed by surgery.
