The Internal Oblique Muscle Flap with Synthetic Mesh Reinforcement for a Large, Contaminated Abdominal Wall Defect.

We report a case of a large mediocaudal abdominal defect in contaminated circumstances with no residual rectus abdominis muscle that was reconstructed using an internal oblique muscle flap with large-pore polypropylene mesh reinforcement. The internal oblique muscle flap can reconstruct the lower abdominal midline without leaving any additional conspicuous scar. Previous studies showed that large-pore polypropylene mesh in contaminated wounds has a minimal difference in terms of infection rate, and less frequent occurrence of hernia, compared even with biological meshes. We believe that this method could be a strong and cosmetically satisfying option for large mediocaudal abdominal wall reconstruction.
