Figure 2. Representative views at the 90-day follow-up assessment. Parietex composite adhesions merely to the mesh edge do not contribute to the total adhesion score. Permacol cecum adhered to the mesh. Surgisis I without adhesions and with minimal incorporation (2 of 7). Surgisis II complete coverage with adhesions and full incorporation (5 of 7). Dashed line marks the original size of the mesh.
Shrinkage
At 30 days, Surgisis showed signi cantly more shrinkage (39 %; IQR, 37.1– 50.6 %) than any of the other meshes. More shrinkage occurred with both Permacol (13.7 %; IQR, 8.6–22.6 %) and Strattice (16 %; IQR, 14.3–19.2 %) than with Parietex composite. No signi cant di erences were seen between Prolene (11 %; IQR, 8.6–16.2 %) and Parietex composite (9 %; IQR, 5.7–13.6 %). At 90 days, Surgisis resulted in signi cant more shrinkage than any of the other meshes (65 %; IQR, 42.4–74.3 %) (Figure 4). The percentage of shrinkage shown by Strattice (28 %; IQR, 22.9–28.0 %) was signi cantly higher than that shown by Prolene (16 %; IQR, 11.4–18.5 %). After 90 days, Parietex composite mesh demonstrated shrinkage of 23 % (IQR, 9.7–31.7 %), and Permacol exhibited shrinkage of 17.7 % (IQR, 12.2–23.8 %). All the meshes except Prolene and Permacol showed signi cantly more shrinkage at 90 days than at 30 days.
