No significant difference in the occurrence of IAA after LA versus OA was found. The patients with complicated appendicitis experienced a greater number of IAA than the patients with uncomplicated appendicitis.

Epidemiologic study, level III.

Permacol elicits increased protease expression and reduced cellular and vascular infiltration compared with AlloDerm 90 days after implantation, indicative of delayed remodeling induced by cross-linking. Increased understanding of the host response to implanted materials ultimately will enable the development of improved meshes with enhanced wound healing properties and fewer graft-related complications.
