RESUMO
STUDY OBJECTIVE: To develop a nomogram for predicting the type of ureteral procedure in pelvic deep endometriosis (DE) surgery (1) and to describe the factors and complications associated with the ureteral procedure (2). DESIGN: Retrospective monocentric study of 920 patients who underwent surgery for pelvic DE between June 2009 and March 2020 in the gynecologic surgery department of the Versailles Hospital Center. The main criterion was evaluation of the ureteral procedure, classified as simple (isolation of the ureter) or complex (dissection of the ureter, segmental ureteral resection, or nephroureterectomy). Postoperative complications, including ureteral stenosis and fistula formation, were tabulated. SETTING: Tertiary referral hospital and expert center in endometriosis. PATIENTS: A total of 920 patients with DE. INTERVENTIONS: Ureteral procedure during surgery for DE. MEASUREMENTS AND MAIN RESULTS: In total, 724 patients (79%) underwent a ureteral procedure, of which 307 (33%) were complex, including 17 (1.8%) segmental ureteral resections. In multivariate analysis, the predictive variables for a complex ureteral procedure were age (p = .036), a previous surgery for endometriosis (p <.01), and ureteral dilatation on magnetic resonance imaging (p <.001). The area under the curve for the model predicting a complex ureteral procedure was 0.68 (95% confidence interval, 0.60-0.71). A complex ureteral procedure was associated with a 3.5% rate of ureteral fistula (n = 15). CONCLUSION: Age, a previous surgery for endometriosis, a rectovaginal nodule size ≥30 mm, endometriotic involvement of the rectum or sigmoid, and ureteral dilatation are significantly associated with a complex ureteral procedure. Our results allowed us to build a nomogram that can be used to better inform patients, anticipate the therapeutic strategy, and optimize the modalities of postoperative surveillance.

Abdominal wall is a rare location for endometriosis, with a reported incidence of parietal endometriosis of approximately 0.03 to 0.4%. It most often occurs in the aftermath of a caesarean section and is associated with pelvic endometriosis in only 5 to 15% of cases. Rare cases of malignant transformation have been described, mainly in the form of clear-cell tumours. We report the case of a 52-year-old patient with a history of endometriosis who presented with a retractile parietal mass at the level of her caesarean scar. Histological analysis confirmed a clear-cell adenocarcinoma (CCC). Few cases of endometriosis - associated CCC are described in the literature. A review of the literature suggests radical surgical treatment combined with adjuvant radio-chemotherapy. However, the prognosis is poor. The aim of this case report is to suggest the diagnosis of malignant transformation in the presence of a rapidly evolving parietal mass in the context of endometriosis and a history of caesarean section.

STUDY OBJECTIVE: To assess face and construct validity of a new virtual reality (VR) training simulator for hysteroscopic placement of tubal sterilization implants. DESIGN: Nonrandomized, controlled trial comparing responses and performance of novices and experts on the simulator. DESIGN CLASSIFICATION: Canadian task force II-1. SETTING: Forty-six gynecologists were personally invited or recruited at the 33rd Conference of the French National College of Gynecologists and Obstetricians (CNGOF) from December 9 to 12, 2009, grouped as 20 experts and 26 novices. They all performed the defined sequence of virtual procedures on the simulator (case 1 for familiarization, case 4 for study assessment) and finally completed the study questionnaire. MEASUREMENTS AND MAIN RESULTS: Responses to realism, educational potential, and general opinion were excellent, proving face validity. Significant differences between novices and experts were assessed for 7 of the 15 metrics analyzed, proving construct validity. CONCLUSIONS: We established face and construct validity for EssureSim, an educational VR simulator for hysteroscopic tubal sterilization implant placement. The next steps are to investigate convergent and predictive validity to affirm the real capacity of transferring the skills learned on the training simulator to the patient in the operating room.

BACKGROUND: The aim of this study was to report the false-negative rate of positron-emission tomography (PET) /Computed Tomography (CT) for para-aortic (PA) lymph node (LN) metastasis and to examine if PA lymphadenectomy could be omitted when PET/CT of the pelvic area is negative. PATIENTS AND METHODS: Patients without evidence of extrapelvic disease on preoperative imaging or in the PA area were included. Each patient underwent a laparoscopic PA lymphadenectomy. RESULTS: A total of 61 patients were included. Seven patients (11%) had PALN metastasis. The false-negative rate of PET/CT was 11%. When PET/CT was positive for pelvic nodes, the risk for PA metastasis was 18% versus 8% when PET/CT was negative in the pelvic area (p=0.24). CONCLUSION: The apparent low sensitivity of the PET/CT does not make it a relevant alternative to surgical LN staging when no uptake is visualized in the PA area. However, for patients in whom PET/CT is negative in the pelvic area, the risk of metastasis in the PA area is low.
