Placing lightweight polypropylene mesh with an omega-3 fatty acid barrier coating intraperitoneally results in more favorable adhesion characteristics compared with Composix and Proceed meshes at 120-day explantation after intraperitoneal placement. The minimal amount of contraction and favorable tissue response in comparison to other commercially available meshes makes C-Qur mesh a practical alternative for laparoscopic and open ventral hernia repair.
