Comparison of the Efficacy and Safety of Thoracoscopic Surgery and Conventional Open Surgery for Congenital Diaphragmatic Hernia in Neonates: A Meta-analysis
Abstract
Background: Thoracoscopic surgery is an increasingly popular surgical technique for the repair of congenital diaphragmatic hernias. We performed a meta-analysis to compare the efficacy, safety of thoracoscopic surgery and the conventional open surgical approach for congenital diaphragmatic hernia in neonates. MATERIALS AND METHODS: A systematic search of electronic databases such as PubMed, Google, and Web of Science was performed to identify studies comparing thoracoscopic surgery and open surgery for congenital diaphragmatic hernia. A total of 6 studies with 3348 patients were found. Parameters such as operation time, hospital stay, recurrence rate, postoperative mortality, and postoperative complications were pooled and compared by meta-analysis. Results: Of the 3348 children with congenital diaphragmatic hernia included in the 6 studies, 615 underwent thoracoscopic surgery and 2733 underwent open surgery. All studies were nonrandomized controlled trials. The operation times were shorter for thoracoscopic surgery than for open surgery in three studies, but there was no significant difference (standard mean difference = 1.25, confidence interval [CI] = [−0.48–2.98], P = 0.16). In the thoracoscopic surgery group, the rate of postoperative deaths was significantly lower (95% CI = 1.24–2.75), but the occurrence of recurrences was more frequent (95% CI = 0.08–0.23). The hospital stay varied significantly across studies. There was a statistically significant difference (standard mean difference = −1.47, CI = [−2.24–−0.70], P < 0.001) in the overall effect between the groups. The complication rate was significantly lower with thoracoscopic surgery compared to open surgery (odds ratio = 0.26, CI = [0.10–0.66], P = 0.004) for the overall effect between the groups. The thoracoscopic procedure, however, was planned for milder and stable cases. Conclusion: Thoracoscopic repair of congenital diaphragmatic hernia in neonates is associated with a shorter length of hospital stay, fewer complications, and less postoperative mortality than traditional open repair. However, the rate of recurrence was found to be higher in those who underwent thoracoscopic surgery.
