Abstract
Objective: The objective of this study was to evaluate the role of mast cells in the postoperative inflammatory response after implantation of prosthetic mesh to repair abdominal wall defects in Wistar rat. Materials and Methods: An abdominal wall defect (30 x 20 mm) was created in the anterior abdominal wall of 25 adult male Wistar rats. The anatomical defect was then repaired with one of the two type’s meshes. Fibroin and monocryl ultrapo prolene meshes. Fibroin meshes were manufactured by weaving its threads, the polypropylene mesh was bought to Johnson & Johnson-Ethicon. After 28 days of implantation Wistar rats were sacrificed and the mesh with abdominal tissue was extracted. Subsequently the samples were treated with histochemical techniques for histological analysis. Results: The study reported adherence to omentum in both types of meshes used, however, the polypropylene mesh showed widely adhesions to colon, slight to intestine and liver, also in a very lower amount, adhesions to omentum. It was found that mast cells were presented in all the studied regions for the polypropylene mesh (dermis, perimysium, and visceral serosa). Discussion: Studies indicate that mast cells and their products such as histamine, serotonin, and others play a key role in controlling local inflammation, wound healing, adhesions, and reactions to foreign bodies in vivo. Conclusion: We can conclude that this study is a good step to show the possible role of mast cells in the abdominal wall repair process.
