| Abstract | ||
| The research was designed to know the difference between non absorbable synthetic material (polypropylene mesh) and natural muscle auto graft (latissmus dorsi muscle) to repair diaphragmatic hernia in dogs. Twelve adult dogs from both sexes was used. The animals was divided into two groups, each group consists of six animals. In all animals, diaphragmatic defect was induced by removal a circular piece about 5 cm in diameter from muscular part of diaphragmatic tissue. The defect was left without any surgical intervention for about 3 weeks until occurrence the ideal feature of diaphragmatic hernia though by depending on the clinical and radiological signs for each animal. In first one, the diaphragmatic hernia was closed by using polypropylene mesh while in second group the hernia was treated by application piece of latissmus dorsi muscle. The evaluation of each graft in all animals was established by study the gross and histopathological changes at 7 and 21 postoperative days. The study was showed a differences between each graft where the repair of hernia in first group with polypropylene mesh lead to adhesion formation less than in second group, furthermore the infiltration of mononuclear inflammatory cells was less than second group, also the interposed of collagen fibers extension between the diaphragmatic tissue and polypropylene mesh was rapidly develops as compared with muscles grafting additionally the grafting with muscle was lead to sever inflammatory reaction. In conclusion, we can use polypropylene mesh and latissmus dorsi muscle for repairing diaphragmatic hernia in dogs but each method have advantage and disadvantage where in spite of polypropylene mesh was characterized by less inflammatory reaction with rapid healing rather than muscle piece but its more expensive. | ||
