Three varieties of congenital diverticulum of the intestine.

The most common intestinal anomaly is the persistent of Meckel's diverticulum, a vestigial structure arising from the terminal ileum. It is present in about 2 per cent of the population and is usually said to be more frequently found in males than in females. This is because more males than females suffer from Meckel's diverticulum disease. The sex bias disappears when the diverticulum is reported incidental to surgery or autopsy. This is illustrated in a short series of our own.
