The study aimed to develop a quantifiable approach to identify a dome shape of the repaired diaphragm using post-operative chest radiograph and to determine if a dome-shaped prosthetic patch repair is associated with a decreased rate of CDH recurrence. The results showed that a dome-shaped repair may reduce recurrence following prosthetic patch repair of congenital diaphragmatic hernia.
A B S T R A C T Purpose: To develop a quantifiable approach to identify a dome shape of the repaired diaphragm using post-operative chest radiograph and to determine if a dome-shaped prosthetic patch repair is associated with a decreased rate of CDH recurrence.Methods: We conducted a retrospective review of all neonates evaluated at our institution from January 2004 to August 2017 with left-and right-sided CDH with at least 6 months of follow-up after CDH repair. Patch use, post-operative imaging and postnatal outcomes were analyzed. Neonates with patch repair were divided into two groups based on the presence of a dome. Using postoperative chest radiographs, the presence of a dome was classified as having a vertical-horizontal diaphragm ratio (VHDR) greater than 20%. Primary outcome was CDH recurrence after repair. Results: We identified 192 neonates who met our inclusion criteria. Cohort survival was 96%, recurrence rate was 15%, 78% had a left-sided CDH; 54% received a patch repair, of which 58% had a type C defect. Of the 104 infants with patch repairs, the CDH recurrence rate was 22% ( n = 23) at a median age of 8.5 months (3.8, 20.1). Although neonates with a dome repair had more ECMO use and longer hospital stay, their recurrence rate was about half of those with a non-dome repair (14% vs 28%, p = 0.07).Conclusions: A dome-shaped repair may reduce recurrence following prosthetic patch repair of congenital diaphragmatic hernia. A larger, multi-institutional study is needed to statistically validate this clinically significant observation.Type of Study: Retrospective review.Level of Evidence: III.(c) 2021 Published by Elsevier Inc.
