Introduction:
Patients with congenital diaphragmatic hernia (CDH), gastroschisis, and omphalocele are prone to abnormalities of intestinal rotation and thus future midgut volvulus. Controversy exists whether routine preemptive Ladd procedure in this subgroup of asymptomatic patients is of value to reduce future volvulus.
Methods:
The Pediatric Health Information System (PHIS) database was queried for neonates with CDH, gastroschisis, and omphalocele between January 2009 and September 2015. Standard univariate and multivariate analysis was completed to compare risk of volvulus between patients treated with a preemptive Ladd versus no Ladd (p<0.05).
Results:
Seven thousand seven hundred forty-nine neonates with CDH (40%), gastroschisis (38%), omphalocele (14%), and abdominal wall malformation (NOS) (9%) were identified. Overall, 3.6% (n=279) had a preemptive. Thirty-two patients had subsequent volvulus. Ladd procedure did not reduce volvulus readmissions for any diagnosis and was associated with a significantly increased risk of volvulus for omphalocele patients (9.1% vs 0.1%, p<0.001). Overall, a Ladd procedure during the index admission was associated with a higher risk for volvulus (1.4% vs. 0.4%, p=0.021) and was associated with a 3.28 increased odds ratio of future volvulus (95% CI 1.12-9.68).
Conclusion:
Ladd procedure performed prophylactically in patients with CDH, gastroschisis, and omphalocele did not reduce subsequent volvulus.
