Template:ICD-11 Meckel diverticulum table

From Embryology
 ICD-11 LB15.0 Meckel diverticulum - congenital abnormality characterized by the outpouching or sac formation in the ileum. It is a remnant of the embryonic yolk sac in which the vitelline duct failed to close. During early gestation, the ompahlomesenteric or vitelline duct connects the fetal yolk sac to the primitive gut. By 7-8 weeks of gestation, this duct is normally completely obliterated. A Meckel diverticulum results when this structure fails to resorb completely.
