- Mesh reinforcement is standard in ventral hernia repair, but the optimal anatomical mesh placement is debated.
- This Danish nationwide cohort study compared reoperation risks for recurrence and bowel obstruction across different mesh placements in elective primary ventral hernia repair for defects ≤10 cm.
- Included patients (n=17,832) had onlay, retromuscular, preperitoneal, or intraperitoneal onlay mesh (IPOM) placement, with a mean age of 54 years and 27.3% female.
- Compared to onlay mesh, retromuscular placement and IPOM were associated with increased risks of reoperation for recurrence (HR 1.63 and HR 1.38, respectively).
- Retromuscular placement and IPOM also showed higher risks of bowel obstruction compared to onlay (HR 2.01 and HR 3.47, respectively).
- The study concludes that onlay and preperitoneal mesh placements may be preferable due to lower risks of recurrence and bowel obstruction.
