Aas‐Eng MK, Dauser B, Lieng M, et al. - Researchers conducted an observational multicenter study of symptomatic women who were scheduled for surgical treatment of rectosigmoid deep endometriosis (DE), with the aim to determine the accuracy of transvaginal sonography (TVS) for presurgical evaluation of the distance between the most caudal part of the endometriotic lesion and the anal verge (lesion‐to‐anal‐verge distance (LAVD)) compared with intraoperative measurement (IOM). Further, they evaluated the agreement between anastomosis height and LAVD determined using TVS. They included a total of 147 consecutive women who were scheduled for surgical treatment of rectosigmoid DE, by either discoid or segmental resection, between April 2017 and September 2019. Observations revealed an elevated risk of complications, such as anastomotic leakage and rectovaginal fistula, if treated surgically, in correlation with a short distance between the bowel lesion and the anal verge in these women. They indicated transvaginal sonography to be a cost‐effective, non‐invasive approach to precisely examine lesion height presurgically. This is of pivotal significance in decreasing the risk of complications and necessity for a temporary stoma, and could improve patient counseling.
