BORQUEZ M, Pablo et al. Collagen and elastic fibers of skin connective tissue in patients with and without primary inguinal hernia. Rev. méd. Chile [online]. 2003, vol.131, n.11, pp.1273-1279. ISSN 0034-9887.

There are few studies looking for collagen matrix defects in patients with inguinal hernia. Aim: To study the skin connective tissue in patients with and without inguinal hernia. Patients and methods: Skin from the surgical wound was obtained from 23 patients with and 23 patients without inguinal hernia. The samples were processed for conventional light microscopy. Collagen fibers were stained with Van Giesson and elastic fibers with Weigert stain. Results: Patients without hernia had compact collagen tracts homogenously distributed towards the deep dermis. In contrast, patients with hernia had zones in the dermis with thinner and disaggregated collagen tracts. Connective tissue had a lax aspect in these patients. Collagen fiber density was 52% lower in patients with hernia, compared to subjects without hernia. No differences in elastic fiber density or distribution was observed between groups. Conclusions: Patients with inguinal hernia have alterations in skin collagen fiber quality and density (Rev Méd Chile 2003; 131: 1273-79)
