Fig. 4.

Synthetic mesh with tight apposition was adherent to the abdominal wall and often embedded into the abdominal muscle regardless of injury: tight apposition, no injury (A), and tight apposition, with injury (D). Histologically, a classic foreign body inflammatory response was noted, extending into the muscle, and encapsulating the synthetic plastic fibers of the mesh: tight apposition, no injury (B, C), and tight apposition, with injury (E, F). Black squares in images B and E are magnified and shown in images C and F, respectively. Scale bars = 2.5 mm in B and E, 500 µm in E and F.
