Effectiveness of the combined use of lactic acid film and polypropylene mesh in the formation of intraperitoneal adhesions--an experimental model in rats.

Objective: To evaluate the efficacy of a lactic acid biomaterial (SurgiWrap®) as a protector of the polypropylene mesh (Marlex®) regarding the formation of intraperitoneal adhesions in rats.

Methods: Forty Wistar rats formed the following groups: Group 0 (Sham)--only laparotomy; Group I--polypropylene mesh; Group II--polypropylene mesh protected by a film of lactic acid. These animals were submitted to laparotomy and placement (or not) of the meshes at closing.

Polylactic acid film versus acellular porcine small intestinal submucosa mesh in peritoneal adhesion formation in rats.

Purpose: To assess intraperitoneal adhesion formation in rats after the single implantation of intraperitoneal polypropylene mesh versus SIS mesh, and the effect of PAF as a polypropylene mesh barrier.

Methods: A total of 55 albino rats randomized into three groups were assessed. The type of adhesions, the percentage of mash covered with adhesions, and the rupture strength of the adhesions were evaluated.
