Abstract
Hernias are known to have deleterious effects on the productive and reproductive
performance of patient. Meshes are used in the repair of hernias with large ring, but they
are neither readily available nor affordable. This study was therefore aimed at finding a
cheaper alternative by comparing nylon and polyvinyl chloride (PVC) coated fibre glass
nets with the standard (ethicon®) mesh for experimental hernia repair in 9 Kano brown
goats divided into three groups of 3 animals each. Vital and haematological parameters
were assessed pre- and postsurgery. The tensile strengths, safety and efficacy of the two
nets and their cost efficiency were also assessed. There was no significant (P 0.05)
difference, in the vital and haematological parameters between the groups, pre- and
postsurgery, except for significant (P 0.05) increase in PCV and Hb on day 8 postsurgery
in the nylon group and also eosinophils and band neutrophils on day 3 postsurgery in the
PVC group. There was 1.3N/mm2 (7.5%) and 0.8N/mm2 (1.6%) decrease in tensile strength
of the nylon and PVC, respectively, post-sterilization. No complications noticed, except for
the slight seroma observed 3 days postsurgery in an animal each, from the PVC and the
ethicon® groups. The histopathology result revealed numerous new blood capillaries with
few fibroblasts and macrophages. The nylon and PVC nets were also found to be 48,781
and 43,478 times, respectively, cheaper than ethicon® mesh. In conclusion, the nylon and
the PVC coated nets can serve as a good substitute for the standard meshes for hernioplasty
in goats, and can therefore, be recommended for such use in Veterinary surgery.
