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.
Some suggest that these neoplasms arise either from the Schwann cells of the gastrointestinal tract or from the neural crest melanoblastic cells, which migrate to the distal ileum through the omphalomesenteric canal [6].
Embryopathy related with methamizole in the first trimester occurs in 2-4/100 babies and includes aplasia cutis, cleft palate-lip, Down syndrome, choanal atresia, tracheo-esophageal fistula, hiatal hernia, tracheomalacia, hypertrophic pyloric stenosis, hypothelia, athelia, omphalocele, anomalies of the omphalomesenteric ductus, hearing deficit, atrial septal defect, ventricular septal defect, patent ductus arteriosus, pulmonary stenosis, imperforated anus, hypospadias, anencephaly, polydactilia, small ear, broad and dispersed eyebrows, and broad nasal root (9).
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.
ATD was first introduced by Fitz in 1844 as "persistent omphalomesenteric remnants"6.
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 remnant of the omphalomesenteric duct which is normally obliterated by the 5th to 8th week of gestation.
Meckel's diverticulum is a remnant of omphalomesenteric or vitelline duct [7].
This pattern can be seen with complete midgut volvulus and bowel ischemia, but it can also be seen with low intestinal obstructions of other etiologies, including volvulus around an omphalomesenteric duct remnant.
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).
