Patch repair of congenital diaphragmatic hernia is not at risk of poor outcomes

Abstract Purpose Recurrence of congenital diaphragmatic hernia (CDH) was retrospectively evaluated after correction with or without a patch in an institution where tension-free repair is advocated. Methods Demographics and outcomes of patients with a postero-lateral CDH repaired (2000–2016) were analyzed (univariate tests and binary logistic regression adjusting for time since start of study, gender, defect side, liver herniation, patch , surgical approach, absence of postero-lateral rim and length of follow-up). Results Of 203 patients, 107 received a patch (P), and 96 were not patched (NP). Groups were not different for gestational age birthweight, gender, defect side and minimally invasive approach rate. Preoperative ECMO incidence (P:29.9% vs. NP:2.1%, p  Conclusion In this single centre series where tension-free repair was advocated, patch repair of CDH was not associated with higher recurrence, though access route was.
