“…When deep endometriosis affecting the rectosigmoid is clinically suspected, whether or not in association with lesions in other areas of the pelvis, it is fundamental to perform an adequate imaging exam capable of indicating whether one or more lesions are present, the size and depth of the lesion(s) and the distance between the lowest lesion and the anal verge (Chapron et al, 2004;Goncalves et al, 2009). With this information, it is then possible to define the treatment option to be implemented, bearing in mind that, when medical therapy fails in relieving painful symptoms, the most comprehensive surgical procedure is an adequate form of pelvic pain management, improving patient's quality of life and reducing recurrence rates of the disease, a situation generally confused with the persistence of lesions following incomplete surgical procedures (Kavallaris et al, 2003;Garry et al, 2000;Remorgida et al, 2005;Vignali et al, 2005;Dubernard et al, 2006).…”
