The timing of surgical repair in patients with congenital diaphragmatic hernia has been a controversial topic over the years, and there is still no agreement as to whether immediate repair or late surgery with preoperative stabilization is preferable. To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. We identified four systematic reviews including 38 studies overall, of which two were randomized trials. We concluded it is not clear whether immediate surgical repair in congenital diaphragmatic hernia increases mortality or decreases hospitalization days compared to late repair because the certainty of evidence is very low.
