This systematic review and meta-analysis evaluated the outcomes of thoracoscopic repair for congenital diaphragmatic hernia (CDH) over time, analyzing 27 studies with 9,396 patients. The overall recurrence rate after thoracoscopic repair was significantly higher than open repair (RR 2.43, 95% CI 1.88-3.14, p < 0.001), but post-2015 studies showed improved comparability (RR 1.43, 95% CI 0.81-2.54).
Key findings
- Overall recurrence after thoracoscopic repair was significantly higher than open repair (RR 2.43, 95% CI 1.88-3.14, p < 0.001).
- Post-2015 studies showed improved recurrence rates, with RR 1.43 (95% CI 0.81-2.54).
- Meta-regression indicated a significant temporal reduction in recurrence disadvantage (p = 0.0059).
- Mortality was lower in the thoracoscopic group, likely due to selection bias.
Why it matters
Understanding the evolving outcomes of thoracoscopic repair for CDH is crucial for clinicians, as it informs surgical decision-making and patient selection, particularly in light of improving techniques and outcomes over time.
