Down’s Syndrome - Etiology and Mechanism Revisited.

The Vitello-intestinal duct remnant is one of the rare congenital anomalies associated with the primitive yolk stalk. Most Vitello-intestinal duct remnants tend to be Meckel’s diverticulum; however, the occurrence of a Vitello-intestinal cyst is very rare. Vitello-intestinal duct remnants are present in 2% of the population. This report describes a case of Vitello-intestinal cyst with fibrous Meckel’s band causing intestinal obstruction in a 13yr old male patient. The patient presented to opd with signs of intestinal obstruction, ultrasound was suggestive of Urachal cyst. Laparotomy was done, a cystic swelling of about 5cm x 4cm was seen beneath umbilicus and a fibrous band was connecting the cyst with ileum near mesenteric border. The cyst along with band was resected and the rent in the ileum was closed. Histopathology of the specimen was done which confirmed the tissue as remnant of Vitello-intestinal duct.
