Prognostic factors in omphalocele and gastroschisis
Insights
Survival rates for omphalocele and gastroschisis are 67% and 73%, respectively. For omphalocele, associated abnormalities and low birth weight impact survival, while gastroschisis mortality is linked to intestinal or wound complications.
Area of Science:
- Pediatric Surgery
- Neonatal Care
- Congenital Anomalies
Background:
- Omphalocele and gastroschisis are congenital abdominal wall defects.
- These conditions require complex surgical management in neonates.
Purpose of the Study:
- To review outcomes and identify factors affecting mortality in infants with omphalocele and gastroschisis.
- To compare the effectiveness of different treatment modalities.
Main Methods:
- Retrospective review of 79 omphalocele and 44 gastroschisis cases over 10 years.
- Analysis of defect size, visceral involvement, birth weight, comorbidities, and treatment complications.
Main Results:
- Survival rates were 67% for omphalocele and 73% for gastroschisis.
- In omphalocele, associated abnormalities and low birth weight were key mortality factors.
- Gastroschisis mortality was primarily due to intestinal or wound complications.
Conclusions:
- Associated abnormalities and low birth weight significantly influence omphalocele survival.
- Primary repair of gastroschisis is preferred over silon pouch use due to fewer complications.
- Silon pouch should be reserved for cases where primary repair is not feasible.
Abstract:
Size of the abdominal wall defect, viscera exposed or herniated, birth weight, associated medical conditions and congenital anomalies, mode and complications of treatment, and the use of total parenteral alimentation was reviewed in 79 cases of omphalocele and 44 cases of gastroschisis treated in the past 10 yr. Sixty-seven percent of infants with omphalocele and 73% of those with gastroschisis survived. In omphalocele, the most important factors affecting mortality were the presence of other associated abnormalities and low birth weight. The size of the abdominal wall defect, the viscera herniated, and the mode of treatment did not appear to affect mortality. In gastroschisis, the size of the abdominal defect, birth weight, viscera exposed or herniated, and associated anomalies were not significant factors affecting mortality. Mortality was usually secondary to intestinal or wound complications. Statistical analysis could not prove that primary repair resulted in greater survival than the use of a silon pouch, but analysis of complications clearly indicates that the former method is preferable and that silon pouch should be reserved for cases in which primary repair is not possible.
