Prolapsed Meckel's diverticulum through an intact omphalocele sac.

A full-term male neonate presented at birth with a small omphalocele and a mucosa-lined tubular structure protruding from the margin of an intact sac. Clinical examination revealed no additional anomalies. Surgical exploration identified the protruding structure as a Meckel's diverticulum arising from the distal ileum. Tangential resection with transverse primary closure was performed, followed by excision of the omphalocele sac and umbilicoplasty. Histopathological examination confirmed Meckel's diverticulum without ectopic mucosa. The postoperative course was uneventful, with good functional and cosmetic outcomes. This case demonstrates an unusual manifestation of Meckel's diverticulum in a minor omphalocele and highlights the importance of meticulous inspection of omphalocele contents and timely operative management to prevent avoidable complications.
