Xenogenic Acellular Pericardium Matrix of Caprine and Porcine Origin for Abdominal Wall Reconstruction in Rabbits

Abstract

Background: The abdominal wall defects require urgent medical attention owing to the voluminous visceral content and uneven wound edges, which remains a clinical challenge for the surgeon. In the present study, xenogenic porcine and caprine acellular pericardium matrix was evaluated for surgical reconstruction of the induced abdominal wall in rabbits. Methods: All total eighteen adult rabbits were divided into three equal groups. The defects were corrected with acellular caprine and porcine pericardium matrix in Group A and B, respectively and Group C was kept as control. Various parameters viz clinical, gross evaluation of surgical wound, degree of adhesion and histopathological changes were evaluated as per standard methods. Result: Clinical parameters and gross changes of the surgical wound showed significant changes on the 3rd and 5th day in all the groups. TLC, Serum Alkaline Phosphatase and Total Protein showed significant variation in Group A and B on the 10th day. Macroscopic and histopathological evaluation of implanted mesh has shows better host tissue proliferation in both the groups. Acellular caprine and porcine pericardium can be good options as bio-mesh for the repair of the abdominal wall and the subject may be considered for in-depth studies and further research programs.
