Transvaginal sonography accurately measures lesion‐to‐anal‐verge distance in women with deep endometriosis of the rectosigmoid

OBJECTIVES: First, to investigate 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)) in women with rectosigmoid deep endometriosis (DE), compared with intraoperative measurement (IOM). Second, to assess the agreement between anastomosis height and LAVD measured using TVS. METHODS: This was a …
