Persistent omphalomesenteric duct is a rare congenital anomaly and protrusion of the bowel through the duct is the only neonatal emergent clinical entity associated with this condition.
During embryonic development, the omphalomesenteric duct (Omphaloenteric duct, vitelline duct or yolk stalk) normally connects the embryonic midgut to the yolk sac ventrally, providing nutrients to the midgut during embryonic development.
Incomplete obliteration of the omphalomesenteric duct is considered as the cause for this anomaly.
The most common of these congenital lesions is Meckel diverticulum, a remnant of the omphalomesenteric duct that communicates with the antimesenteric border of the bowel and hence has a separate blood supply from the intestine.
Omphalomesenteric duct (OMD) remnants and omphalocele are not infrequently seen in paediatric patients.
Although small-bowel obstruction is common, persistent omphalomesenteric duct as a cause of this condition is an exceptionally rare finding.
Meckel's diverticulum is a true diverticulum of the small bowel resulting from incomplete closure of the omphalomesenteric duct. In the foetus the omphalomesenteric duct connects the yolk sac with a loop of the primitive midgut.
This article reports the discovery during an inguinal herniorraphy in a four years old patient of a Meckel's diverticulum (this entity depends on the vitelin duct persistence, also known as the omphalomesenteric duct).
(38) The diverticulum occurs at the antimesenteric border of the distal ileum and is caused by incomplete obliteration of the omphalomesenteric duct. The diverticulum often contains ectopic gastric and pancreatic mucosa.
