Management of Congenital Abdominal Wall Defects
Summary
Congenital abdominal wall defects, principally gastroschisis and omphalocele, present unique challenges from prenatal detection to long-term follow-up. Early identification through ultrasound permits detailed assessment of defect size, content and associated anomalies. Management pathways hinge on risk stratification: isolated small defects often permit primary closure shortly after birth, whereas large or ruptured defects commonly require staged repair to avoid abdominal compartment syndrome. Multidisciplinary teams coordinate surgical timing with neonatal respiratory support and nutritional optimisation, using techniques such as silo placement or vacuum-assisted closure to gradually reduce herniated viscera. Postoperative care focuses on infection prevention, ventilatory weaning and early enteral feeding to mitigate complications. Outcomes vary globally, with survival rates exceeding 90 per cent in high-resource settings but remaining substantially lower where neonatal intensive care capacity is limited. Advances in prenatal genetic testing and minimally invasive approaches continue to refine prognostic counselling and individualise treatment, while long-term surveillance addresses neurodevelopmental, gastrointestinal and respiratory sequelae.

Management of Congenital Abdominal Wall Defects publication trend
The graph below shows the total number of articles in management of congenital abdominal wall defects across all publications each year (not limited to Nature Index journals).
Technical terms
Omphalocele: Herniation of abdominal viscera through the umbilical ring enclosed in a peritoneal sac.
Gastroschisis: Full-thickness abdominal wall defect lateral to the umbilicus without a covering sac.
Staged repair: A surgical approach using temporary coverage (e.g., silo or mesh) to gradually return abdominal contents before definitive closure.
Abdominal compartment syndrome: Pathological increase in intra-abdominal pressure impairing organ perfusion and function.
Vacuum-assisted closure: Negative-pressure therapy applied to a surgical site to promote fluid removal and tissue approximation.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
