Abstract

The aim of this study was to identify any histological changes between the prolapsed and non-prolapsed vaginal skin to enable us to answer the broader question of whether to excise or re-suture the prolapsed tissue during vaginal reconstructive surgery. Two tissue samples were taken from 20 women who underwent prolapse surgery, one prolapsed and another non-prolapsed tissue. The samples were analysed blind histologically by a pathologist. Our study showed statistically significant differences in three tissue components namely myofibroblast differentiation (0.047), elastin (0.048) and collagen (0.095), depending on whether the tissue was prolapsed or non-prolapsed. However, the study had certain limitations and practical difficulties faced in histological approach of tissue analysis. Histology alone is an insufficient indicator to answer our question and definitive understanding of the prolapsed tissue may result from a randomised study on a larger study population.
