Omphalomesenteric duct cyst in an omphalocele: a rare association.

Omphalomesenteric duct (OMD) remnants and omphalocele are not infrequently seen in paediatric patients. In most of the cases, OMD remnant in an omphalocele is a Meckel's diverticulum; however rarely there may be other lesions. A one-day old male baby underwent surgery for omphalocele. At exploration a 10 x 12 cm cyst containing gut contents was found as the content of the omphalocele, with proximal and distal ileal loops running in continuity with it. Resection of the cyst with end to end primary gut anastomosis was done. Baby also had complex associated cardiac anomalies and died few days after surgery due to sepsis.
