Merkel diverticulum

Meckels diverticulum is a distal ileum diverticulum formed by the degeneration of the yolk duct during embryonic development. It is clinically asymptomatic and is often diagnosed due to complications in the diverticulum. In 1808, Meckel first discovered that the diverticulum originated from the residual yolk duct. In 1812, he made a complete description of his embryology and clinical manifestations and its complications. Therefore, the disease was named Merkel diverticulum. The disease is also occasionally accompanied by other malformations, such as umbilical bulge, poor bowel rotation, repeated bowel malformations, ectopic pancreas and congenital heart disease. Ehrensperger points out that the incidence of associated malformations can be as high as 8.4%.
