Composite, non absorbable parietal prosthesis with polyethylene terephtalate-polyurethane (HI-TEX (R) PARP NT): prevention of intraperitoneal adhesions. Experimental study in rabbit.

The authors report an experimental study in the rabbit with a new composite non absorbable mesh in Polyethylene Terephtalate-Polyurethane used for inc isional hernia repair in intraperitoneal positioning. This new mesh has one permeable side in polyethylene terephtalate for rapid tissue fixation and another side in polyruethane, hydrophob in order to avoid cell penetration. Eighteen rabbits were operated. A wound was created in aponeurose, muscle and peritoneal abdominal wall. The mesh was placed in intraperitoneal posit ioning and was taken off at 4, 9 and 13 months for histologic examination a nd electronic microscopical examination. Tolerance, adhesion, tissular reac tion and neoperitoneum formation have been studied. All the meshes were wel l integrated and without sepsis. in 18% of cases small and monocclusive int raperitoneal adhesions were found. This new composite mesh in intraperitone al positioning gave good results at medium-term in the rabbit. It's an attr active alternative for incision hernias repair with intraperitoneal mesh.
