Minimally invasive surgery for congenital diaphragmatic hernia: a meta-analysis

Objectives:
To compare the safety and efficacy of minimally invasive surgery (MIS) with traditional open surgical approach for congenital diaphragmatic hernia (CDH).
Methods:
A literature search was performed using the PubMed database, Embase, and the Cochrane central register of controlled trials using a defined set of criteria. The outcomes, which include post-operative mortality, incidence of hernia recurrence, rates of patch use and complications, were analyzed.
Results:
We investigated nine studies, which included 507 patients. All studies were non-randomized historical control trials. The MIS group had a significantly lower rate of post-operative death with a risk ratio of 0.26 [95% confidence interval (CI) 0.10-0.68; p = 0.006] but a greater incidence of hernia recurrence with a risk ratio of 3.42 (95% CI 1.98-5.88; p < 0.00001). Rates of prosthetic patch use were similar between the two groups. Fewer cases of surgical complications were found in the MIS group with a risk ratio of 0.66 (95% CI 0.47-0.94; p = 0.02).
Conclusions:
MIS for CDH repair is associated with lower post-operative mortality and morbidity compared with traditional open repair. Although rate of patch use appears to be comparable, the increased risk of CDH recurrence should not be ignored. The lack of well-controlled prospective trials still limits strong evaluations of the two surgical techniques.
