We report the case of a successful vaginal delivery following laparoscopic abdominal wall reconstruction in an adult survivor of an omphalocele without prior surgical repair. Untreated omphaloceles are rare in adulthood. A 30-year-old female patient presented with a large anterior abdominal wall defect due to an untreated omphalocele, who expressed a desire to have a baby in the near future. A laparoscopic herniorrhaphy was performed with a double-layered expanded polytetrafluoroethylene (ePTFE, Gore-Tex) mesh. The patient delivered a full-term healthy baby vaginally 2 years after surgical repair of the omphalocele.
