Abstract
Purpose
The ideal location for mesh placement in minimally invasive ventral hernia repair (VHR) is still up for debate. We undertook a systematic review and meta-analysis (SRMA) to evaluate the outcomes of patients who received intraperitoneal mesh versus those that received extraperitoneal mesh in minimally invasive VHR.
Methods
We searched PubMed, EMBASE, Cochrane, and Scopus from inception to May 3, 2021. We selected studies comparing intraperitoneal mesh versus extraperitoneal mesh placement in minimally invasive VHR. A meta-analysis was done for the outcomes of surgical site infection (SSI), seroma, hematoma, readmission, and recurrence. A subgroup analysis was conducted for a subset of studies comparing patients who have undergone intraperitoneal onlay mesh (IPOM) versus extended totally extraperitoneal approach (e-TEP).
Results
A total of 11 studies (2320 patients) were identified. We found no statistically significant difference between patients who received intraperitoneal versus extraperitoneal mesh for outcomes of SSI, seroma, hematoma, readmission, and recurrence [(RR 1.60, 95% CI 0.60–4.27), (RR 1.39, 95% CI 0.68–2.81), (RR 1.29, 95% CI 0.45–3.72), (RR 1.40, 95% CI 0.69–2.86), and (RR 1.22, 95% CI 0.22–6.63), respectively]. The subgroup analysis had findings similar to the overall analysis.
Conclusion
Based on short-term results, extraperitoneal mesh does not appear to be superior to intraperitoneal mesh in minimally invasive ventral hernia repair. The choice of mesh location should be based on the current evidence, surgeon, and center experience as well as individualized to each patient.
