This prospective study evaluated the diagnostic accuracy of various preoperative imaging and examination techniques for distinguishing between isolated rectovaginal septum endometriosis and deep infiltrating bowel involvement in 69 patients. The researchers compared bimanual examination, transvaginal ultrasound, rectal endosonography, sigmoidoscopy, pelvic MRI, and CA-125 levels against histopathological findings obtained during standardized combined vaginal-laparoscopic surgery. Results indicated that all preoperative methods had unacceptably high error rates, with sensitivities ranging from 3% to 92% and specificities from 67% to 100%, rendering them unreliable for determining the extent of infiltration. Consequently, the authors concluded that direct intraoperative assessment is the only method that accurately differentiates between these conditions, as it correlated perfectly with histology. This paper is centrally about endometriosis — specifically the diagnostic challenges and surgical management of deep infiltrating endometriosis affecting the rectovaginal septum and bowel.
