This systematic review and meta-analysis evaluated the outcomes of intraperitoneal onlay mesh (IPOM) versus retromuscular mesh (RM) placement in ventral incisional hernia repair among 916 patients. The study found that RM placement significantly reduced the odds of hernia recurrence compared to IPOM, with an odds ratio of 0.34 (95% CI 0.15, 0.77, p = 0.009).
Key findings
- RM placement significantly reduced hernia recurrence compared to IPOM (OR 0.34, 95%CI 0.15, 0.77, p = 0.009).
- No significant differences in total complications between RM and IPOM (OR 0.95, 95%CI 0.44, 2.04, p = 0.885).
- Both techniques had similar odds of major complications (OR 1.58, 95%CI 0.37, 6.70, p = 0.533).
- Intraoperative complications, operative time, and readmission rates were similar for both techniques.
Why it matters
Understanding the comparative effectiveness of mesh placement techniques in hernia repair is crucial for optimizing patient outcomes. The findings suggest that RM may offer a lower recurrence rate, which is a key consideration in surgical decision-making.
What to keep in mind
The study's findings are based on heterogeneous evidence and varying definitions of recurrence and complications across studies.
