Abstract

To get support from morphological findings to develop a novel surgical procedure for posterior vaginal defect repair, we histologically examined the rectum-vagina interface tissues obtained from 20 elderly female cadavers. The rectovaginal septum (RVS) was defined here as an elastic fiber-rich plate (EFRP) along the posterior vaginal wall. It lined the posterior surface of the vein-rich zone of the vaginal wall and extended between the bilateral paracolpiums. The septum was more evident in the lower half of the interface than in the upper half. The RVS was often thin and interrupted. Since the RVS was not so clearly demonstrated in the upper vagina histologically, augmentation using some implant is considered to be necessary for the enterocele and high rectocele. Since the thickness and tightness of the RVS vary with the case in the lower vagina, surgical procedures for low rectocele repair should be individualized, including implant-augmentation.
