RESUMEN
RESEARCH QUESTION: How do clinical rectovaginal examination and transvaginal ultrasound examination perform in the diagnosis of parametrial infiltration in patients with endometriosis? DESIGN: This was a multicentre prospective observational study. Patients with suspected deep endometriosis at clinical examination and/or at ultrasound evaluation and scheduled for surgery were included. Following multicentre multidisciplinary meetings, consensus was obtained on terms and methodology to define the parametrium at pelvic anatomy, ultrasound and surgery. Sensitivity, specificity, accuracy, and positive and negative likelihood ratios were calculated for clinical and ultrasound examinations with respect to surgery. RESULTS: In total, 195 women were selected for the present study and 164 were included in the analysis. Ultrasound examination had good to high specificity (>80%) for all parameters, except the left lateral parametrium (78.8%). The sensitivity of ultrasound examination was good to high for fixity of the right and left ovaries, uterosacral ligaments, retrocervix and rectovaginal space; and low for the anterior and lateral parametria, vagina, bladder and bowel. Clinical examination had good to high specificity for fixity of the left ovary, anterior parametrium, right uterosacral ligament, retrocervix and vagina; and low specificity for fixity of the right ovary, lateral parametrium, left uterosacral ligament and rectovaginal space. The sensitivity of clinical examination was good for the uterosacral ligaments and rectovaginal space, and low for the remaining parameters. CONCLUSION: Ultrasound examination provided good specificity for all the parameters, but sensitivity was low for the anterior and lateral parametria. Clinical examination provided good specificity for the anterior and posterior parametria, but sensitivity was low for the anterior and lateral parametria. Further prospective studies are needed to validate this methodology and confirm the results.

OBJECTIVE: To evaluate ureteral involvement using transvaginal sonography (TVS) regarding the distortion of the course of the ureters caused by deep endometriosis (DE), which can facilitate predicting the need for ureterolysis during surgery, even in the absence of ureteral stenosis or dilatation. METHODS: This is a single-center, observational, retrospective pilot study of 88 consecutive patients who later underwent surgery for DE that used ultrasound preoperative diagnosis of ureteral medial deviation of one or both ureters between January 2019 and January 2022. At TVS, the course of the ureter was considered medialized if, in longitudinal and transversal section, any distance was detectable between the ureter and the cervix at the point where the ureter crosses the uterine artery. The primary end point was to determine sensitivity, specificity, and positive and negative predictive values of "ureteral medial deviation" diagnosed using TVS, in order to predict the need for ureterolysis. RESULTS: Our series included 88 women with a median age of 39 (interquartile range 33-43) years. Ureteral medialization showed a relatively low false-positive rate (10.9%), with a specificity of 89.1% (95% confidence interval [CI] 81.4%-96.7%) and a sensitivity of 86.6% (95% CI 80.3%-92.9%), along with a high positive predictive value of 93.3% (95% CI 88.4%-98.1%), and a lower negative predictive value of 79.1% (95% CI 69.8%-88.5%), respectively. CONCLUSIONS: This study introduced a new ultrasound sign with a high degree of accuracy to predict ureterolysis and this may have positive implications in the management and surgical planning of patients with ureteral endometriosis.

STUDY OBJECTIVE: The purpose of this study was to evaluate the laparoscopic aspiration of endometriomas through 95% ethanol sclerotherapy. DESIGN: A single-center, retrospective study. SETTING: Endometriosis outpatient clinic of a tertiary university hospital, gynecology department of Agostino Gemelli University Foundation Polyclinic IRCCS, Rome, Italy. PATIENTS: Fifty-three women with 64 identified endometriomas measuring 4 to 10 cm with no suspected malignancy. INTERVENTIONS: Laparoscopic aspiration and 95% ethanol sclerotherapy of endometriomas were completed in the patients between September 2013 and September 2017. MEASUREMENTS AND MAIN RESULTS: Using standard laparoscopy, the ovarian endometriomas were aspirated and washed to remove all cystic material. A 95% ethanol solution was instilled in the cysts and left for 15 minutes, then removed. The patients were followed by ultrasound at 3, 6, 9, and 12 months, and then annually to identify recurrence. All patients were administered postoperative hormone therapy, suspended only in those desiring pregnancy or experiencing adverse effects. The mean age was 32 years (range 19-40 years), and the mean cyst diameter was 6 cm (range 4-10 cm). Thirteen of the 53 patients (25%) had had previous surgery for endometriomas. Forty-one patients (77%) had associated deep endometriosis, treated during the same laparoscopic procedure. No major ethanol-related complications were recorded. The mean length of follow-up was 31 months. Recurrence of endometriomas was observed in 5 patients (9%). Overall, pregnancy occurred in 16 of 28 patients (57%) desiring pregnancy. CONCLUSION: Laparoscopic aspiration and ethanol sclerotherapy as treatment for endometriomas, even in patients with bilateral endometriomas or with associated deep endometriosis, resulted in <10% recurrence and no major complications.
