Surgical options in the management of large omphaloceles
Insights
Surgical management of omphaloceles in neonates achieved an 87% survival rate. Primary closure offered the best outcomes, while silon chimneys for giant omphaloceles had high mortality and complications.
Area of Science:
- Pediatric Surgery
- Neonatal Care
- Congenital Abnormalities
Background:
- Omphalocele is a congenital abdominal wall defect.
- Management strategies for omphalocele vary, impacting outcomes.
- Giant omphaloceles pose significant surgical challenges.
Purpose of the Study:
- To review outcomes of omphalocele management in neonates.
- To compare different surgical approaches for omphalocele repair.
- To identify safer alternatives for complex omphalocele cases.
Main Methods:
- Retrospective review of 46 neonates with omphaloceles (1975-1985).
- Analysis of outcomes based on surgical management: primary closure, silon chimneys, and sac preservation.
- Evaluation of survival rates, complication rates, and hospitalization duration.
Main Results:
- Overall survival rate for surgically managed neonates was 87%.
- Primary closure group (23 neonates) had 100% survival.
- Giant omphaloceles managed with silon chimneys (13 neonates) showed 46% mortality and high complication rates.
Conclusions:
- Primary omphalocele closure in neonates is highly successful.
- Silon chimneys for giant omphaloceles are associated with significant mortality and complications.
- Preserving the omphalocele sac with topical escharotic agents may be a safer alternative for unreconstructable defects.
Abstract:
Forty-six neonates with omphaloceles seen at the Children's Hospital and Medical Center in Seattle from 1975 to 1985 were reviewed. There was an 87 percent survival rate in those surgically managed. The 23 neonates who underwent primary closure all survived. The 13 neonates with giant omphaloceles with the liver in the defect who received silon chimneys had a 46 percent mortality rate and a high complication rate, with prolonged hospitalization. Two neonates with giant omphaloceles were managed by leaving the sac intact, and silver sulfadiazine cream was used as an escharotic agent. We believe it is a safer alternative than the silon chimney in neonates whose defects cannot be closed primarily.
