Repair of large hernia by polymer graft in goats


Sixth bucks of local breed were used in this study. The animals were anesthetized with mixture of ketamine and xylazine hydrochloride. Ventral abdominal hernias were induced on the lateral ventral abdomen. One month post operation, the induced hernia was repaired with polymer grafts, which fixed by simple interrupted suture, using No. 1 silk suture material. After implantation, there was focal abscess at the operative site in two cases which resolved after evacuation and irrigation with antiseptic. The findings of the microscopic result at 30, 60 and 90 days of grafts implantation exhibited inflammatory reaction around the grafts and later at the 60 and 90 days of implantation there was fibrous tissue formation around implant graft, inflammatory reaction and fibroblast infiltration in the graft. The results indicated that biocompatibility of polymer graft with the host tissue was good with complete healing of the operative site.
