Abstract
PURPOSE: Large congenital diaphragmatic hernias (CDH) can be repaired with either a muscle flap or prosthetic patch. The purpose of this study was to assess the frequency and severity of scoliosis, chest wall, and abdominal wall deformities following these repairs. METHODS: Neonates who underwent CDH repair (1989-2012) were retrospectively reviewed. We then validated our retrospective review by comparing results of a focused radiologic evaluation and clinical examination of patients with large defects seen in prospective follow-up clinic. Tests for association were made using Fisher's exact test. RESULTS: 236 patients survived at least 1year. Of these patients, 30 had a muscle flap, and 13 had a patch repair. Retrospectively, we identified pectus in 9% of primary repairs, 47% of flap repairs, and 54% of patch repairs. We identified scoliosis in 7% of primary repairs, 13% of flap repairs, and 15% of patch repairs. Prospectively, 75% of flap patients and 67% of patch patients had pectus and 13% of flap patients and 33% of patch patients had scoliosis. There was no significant difference between flap and patch patients. CONCLUSIONS: Scoliosis and pectus deformity were common in children with large CDH. The operative technique did not appear to affect the incidence of subsequent skeletal deformity.
