Adhesions
After 28 and 90 days the surfaces of all infected meshes were completely covered with adhesions. Owing to the high infection rate in C-Qur® and Dualmesh® the median adhesion coverage was 90–100% (Figure 2). After 28 days signi cantly less adhesion to the mesh surface was found for Strattice® (median 10.0 (5.0– 10.0) %) and Sepramesh® (12.5 (6.3–22.5) %) compared with all other meshes (P ≤ 0.004 and P ≤ 0.017 respectively). Median adhesion coverage was 45.0% for Parietene Composite®, 52.5% for Parietene® and 55.0% for Omyramesh®. Sepramesh® showed an increase in adhesion formation from a median of 12.5% at 28 days to 60.0% at 90 days (P = 0.010). After 90 days Strattice® (5.0 (5.0–10.0) %) had signi cantly less adhesion coverage than the other meshes (P ≤ 0.003). At 90 days there was no signi cant di erence between median adhesion coverage of Parietene Composite® (35.0%), Omyramesh® (42.5%), Sepramesh® (60.0%) and Parietene® (72.5%).
