[Pelviperineoscopy. Preliminary study of feasibility on cadavers]

The traditional access of perineum for the treatment of the pelvic organ prolapse by vaginal route is probably responsible for the risk of mesh exposure and a longer convalescence. So, endoscopic access to perinemeum needs to be evaluated.

Feasibility study on cadavers. Details of the procedure: opening of the pararectal space by digital dissection first after incision on the level of the posterior commissure. Introduction of an optical trocart to the level of the perineum incision; dissection of pararectal space with optics and CO(2); individualization of the various elements; installation of a transobturator trocart and a transgluteal trocart; dissection of the rectovaginal septum and visualization of the sacrospinous ligament and pudendal nerve. The measured variables were: operational incidents, possibility of creation of working space, dissection of the rectovaginal septum; finally, visualization of the sacrospinous ligament and pudendal pedicle.

On the 4 studied cadavers, we could carry out a dissection of pelvirectal space in all the cases. On the 8 pararectal fosses, in all the cases we could carry out a cavity of dissection and to open the recto vaginal septum, visualization of the sacrosciatic ligament and pudendal pedicle was possible in 6 cases out of 8. There were one rectal injury, two vaginal injuries and one lesion of the pudendal pedicle.

This endoscopic access allows in the majority of cases to see the structures necessary to the realization of a vaginal sacrospinofixation or the installation of posterior mesh without a colpotomy and a traumatic exposure. The incidents are probably due to our inexperience and should disappear in time. The pelvi-perineoscopy is an endoscopic access of perineum which should be evaluated.
