Abdominal Wall Defect Research

Abdominal wall defects present as a various range of anomalies from minor hernias to major abdominal protrusions. The two most common congenital defects include gastroschisis and omphalocele, which have two separate pathophysiologic origins, clinical manifestations, and management/treatment strategies. Advances in the clinical and surgical management of abdominal wall defects have greatly improved the survival of infants born with abdominal wall defects. Our research is focused on continued advances in care to help these children.
