Value of Endorectal Ultrasonography for Diagnosing Rectovaginal Septal Endometriosis Infiltrating the Rectum

Abstract

In terms of its sensitivity and its negative predictive value, anorectal endoscopic ultrasonography is a very effective means of detecting endometriosis of the rectovaginal septum and assessing possible infiltration of the rectal wall. However, this method is not as accurate for nodules located far from the EUS probe, as is the case with the uterosacral ligaments and ovaries.
