Abstract
OBJECTIVE The aim of this study is to determine the accuracy of transvaginal ultrasound (TVU) for the diagnosis of ureteral involvement in women with deep infiltrating endometriosis (DIE). METHODS The meta-analysis included primary studies comparing the use of TVU for diagnosing endometriotic involvement of the ureter, using laparoscopic surgery and histological diagnosis as the reference standard. Search was performed in several databases (Scopus, Web of Science, and PubMed/MEDLINE). The studies' quality and bias risk were assessed using the Quality Assessment of Diagnostic Accuracy Study-2 (QUADAS-2). Diagnostic performance was estimated by assessing pooled sensitivity and specificity. RESULTS A total of 496 citations were found. Six articles were ultimately selected for this systematic review and meta-analysis after the inclusion and exclusion criteria were applied. Pooled sensitivity and specificity were 0.81 (95% CI: 0.42-0.96), 1.00 (95% CI: 0.93-1.00). The heterogeneity observed was high for both sensitivity and specificity. Overall risk of bias was low. CONCLUSION TVU is a valuable tool for the pre-operative identification of ureteral involvement by DIE.

Abstract
In recent years, due to the development of standardized diagnostic protocols associated with an improvement in the associated technology, the diagnosis of pelvic endometriosis using imaging is becoming a reality. In particular, transvaginal ultrasound and magnetic resonance are today the two imaging techniques that can accurately identify the majority of the phenotypes of endometriosis. This review focuses not only on these most common imaging modalities but also on some additional radiological techniques that were proposed for rectosigmoid colon endometriosis, such as double-contrast barium enema, rectal endoscopic ultrasonography, multidetector computed tomography enema, computed tomography colonography and positron emission tomography-computed tomography with 16α-[18F]fluoro-17β-estradiol.

Abstract
This meta-analysis aimed to determine the accuracy of transvaginal ultrasound (TVS) and pelvic magnetic resonance imaging (MRI) in diagnosing urinary tract endometriosis (UTE). A comprehensive search of the Pubmed and Embase was conducted between January 1989 and June 2020. Studies that described the accuracy of MRI or TVS for the diagnosis of UTE using surgical data as the reference standard were included. Of the 913 citations identified, 23 studies were analysed. For detection of endometriosis in bladder endometriosis (BE), the overall pooled sensitivities of TVS and MRI were 72% and 68% respectively, and their specificities were 99% and 100% respectively. For detection of endometriosis in the ureteral endometriosis (UE), the overall pooled sensitivities of TVS and MRI were 97% and 87% respectively, and their specificities were both 100%. In conclusion, both TVS and MRI provide good accuracy with specific strong points in diagnosing UTE and seem useful first-line methods from a clinical perspective. Besides, pelvic MRI and TVS are more accurate for predicting UTE localised in the ureter than bladder, especially in terms of sensitivity.IMPACT STATEMENTWhat is already known on this subject? Previous studies have confirmed high diagnostic value of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) on bladder endometriosis (BE) respectively. However, high heterogeneity was found for both sensitivity and specificity and no meta-analysis has yet been performed to test the diagnostic value of TVS and MRI for ureteral endometriosis (UE).What the results of this study add? In this meta-analysis, we firstly confirmed high diagnostic value of TVS and MRI on UE respectively. For detection of UE, the overall pooled sensitivities of TVS and MRI were 97% and 87% respectively, and their specificities were both 100%.What the implications are of these findings for clinical practice and/or further research? Early preoperative diagnosis and accurate understanding of the widespread distribution of endometriosis are prerequisites for radical surgical in UTE. In the present study, we updated the previous results on the accuracy of TVS and MRI for the diagnosis of BE and firstly confirmed high diagnostic value of TVS and MRI on UE. Both TVS and MRI provide good accuracy with specific strong points in diagnosing UTE and seem useful first-line methods from a clinical perspective.

Abstract
Abstract
Background
Endometriosis is a chronic inflammatory condition with varied presentation, which ultimately leads to chronic pelvic pain and infertility. It is a psychological and economic burden to the women and their families.
Main body of abstract
The literature search was performed on the following databases: MEDLINE, Google Scholar, Scopus, EMBASE, Global health, the COCHRANE library, and Web of Science. We searched the entirety of those databases for studies published until July 2020 and in English language. The literature search was conducted using the combination of the Medical Subject heading (MeSH) and any relevant keywords for “endometriosis related infertility and management” in different orders. The modalities of treatment of infertility in these patients are heterogeneous and inconclusive among the infertility experts. In this article, we tried to review the literature and look for the evidences for management of infertility caused by endometriosis. In stage I/II endometriosis, laparoscopic ablation leads to improvement in LBR. In stage III/IV, operative laparoscopy better than expectant management, to increase spontaneous pregnancy rates. Repeat surgery in stage III/IV rarely increases fecundability as it will decrease the ovarian reserve, and IVF will be better in these patients. The beneficial impact of GnRH agonist down-regulation in ART is undisputed. Dienogest is an upcoming and new alternative to GnRH agonist, with a better side effect profile. IVF + ICSI may be beneficial as compared to IVF alone. Younger patients planned for surgery due to pain or any other reason should be given the option of fertility preservation.
Short conclusion
In women with endometriosis-related infertility, clinician should individualize management, with patient-centred, multi-modal, and interdisciplinary integrated approach.

Abstract
Incidental adnexal masses and uterine findings occur with a high frequency on cross-sectional imaging examinations, particularly in postmenopausal women in whom imaging is performed for a different reason. These incidentalomas encompass a gamut of potential pelvic gynecologic disorders. Most are benign ovarian cysts; however, other less commonly encountered disorders and improperly positioned gynecologic devices may be seen. A knowledge of the management recommendations for such pelvic incidental findings is critical to avoid unnecessary imaging and surgical interventions, as well as to avoid failure in diagnosis and management of some of these conditions.

Abstract
INTRODUCTION The digestive involvement of endometriosis accounts for up to 20-25% of deep localisations. Precise mapping of digestive lesions is essential in order to plan surgery and specialized teams. The aim of this study is to assess the contribution of the MRI-coloscan couple in the preoperative assessment of digestive endometriosis. METHODS We analyzed 45 files of patients referred for suspected digestive endometriosis. They had all undergone a preoperative MRI and coloscan associated with surgery throughout the year. We first compared the data collected in imaging, and then compared the synthesis of this data with the surgical procedure performed. RESULTS 35 patients required digestive surgery. 24 of 45 files were concordant in MRI and coloscanner. Data from MRI alone matched with surgery in 69% of cases, against 84% for the coloscan. The synthesis allowed a concordance of 89%. 25 segmental resections, 2 discoid and 16 shaving were performed. The use of coloscan made up for nine extra cases: the detection of four additional cases of multifocality, a single undiagnosed case of a deep lesion, and allowed to specify the depth of the involvement in four cases. On the contrary, the MRI was correct compared to the CT in four cases. The presence of a digestive surgeon was necessary in 53% of cases. CONCLUSION In the era of imaging staging, it would seem interesting to turn towards a subclassification of the digestive involvement of endometriosis in order to decide which surgery to perform. In our experience, the coloscan is a useful complement of MR, especially to assess the depth of involvement and the multifocality.

Abstract
Objective To optimize prediction for intestinal invasion of epithelial ovarian cancer. It is important to achieve debulking surgery to improve prognosis in ovarian cancer; intestinal resection is adopted if the cancer is invaded and resectable, but the preoperative evaluation method of intestinal invasion is still controversial. Methods Patients (n = 174) who underwent primary debulking surgery for epithelial ovarian cancer were recruited for retrospective study; 28 and 146 patients were classified into the invasion and non‐invasion groups, whether they needed intestinal resection or not. We collected clinical data including evaluation of computed tomography (CT), magnetic resonance imaging (MRI), and barium contrast radiography, and analyzed their accuracy. Results The sensitivity and specificity for intestinal invasion were 33.3% and 98.6%, 42.9% and 98.6%, and 66.7% and 93.9% in CT, MRI, and barium contrast radiography, respectively. CT and MRI combined showed a sensitivity of 58.3% and specificity of 96.9%; all three methods combined was the most sensitive combination, showing a sensitivity of 79.2% and specificity of 90.8%. Conclusion Combination of CT, MRI, and barium contrast radiography predicts intestinal invasion with the highest sensitivity. These three modalities, however, could not predict all intestinal invasion. Patients should be informed of the possibility of unexpected extensive resection. Combination of CT, MRI, and barium contrast radiography give the best prediction of intestinal invasion in ovarian cancer.

Abstract
Double-contrast barium enema (DCBE), transrectal endoscopic ultrasonography (REU), multidetector computerized tomography enema (MDCT-e), and computed tomography colonoscopy (CTC) have been successfully used for the diagnosis of bowel endometriosis. DCBE provides a complete overview of the entire colon and allows detecting cecal nodules. The accuracy of DCBE is operator dependent and, thus, it may have low specificity. It does not allow identifying the cause of the mass effect. DCBE requires the administration of barium and exposure to radiation. REU precisely estimates the distance between the rectosigmoid nodule and the anal verge. However, it allows investigating only the distal part of rectosigmoid, it misses anterior pelvic lesions, and it has poor sensitivity for the diagnosis of endometriomas. MDCT-e is accurate and reproducible in diagnosing intestinal endometriosis and in assessing its characteristics: the largest diameter of the nodule, the distance between the distal part of the nodule and the anal verge, and depth of infiltration of endometriosis in the intestinal wall. MDCT-e requires the administration of iodinated contrast medium (CM) and the exposure to radiations. CTC has good performance in the diagnosis of rectosigmoid endometriosis. It allows estimating the degree of intestinal stenosis CTC, and the distance between the intestinal endometriotic nodule and the anal verge. It requires exposure to radiations, and it may require the administration of an iodinated CM.

Abstract
(1) Objectives: In patients with symptoms suggestive of rectosigmoid endometriosis, imaging techniques are required to confirm the presence and establish the extent of the disease. The objective of the current study was to compare the performance of three-dimensional rectal water contrast transvaginal ultrasonography (3D-RWC-TVS) and computed tomographic colonography (CTC) in predicting the presence and characteristics of rectosigmoid endometriosis. (2) Methods: This prospective study included patients with suspicion of rectosigmoid endometriosis who underwent both 3D-RWC-TVS and CTC and subsequently were surgically treated. The findings of imaging techniques were compared with surgical and histological results. (3) Results: Out of 68 women included in the study, 37 (48.9; 95% C.I. 38.2–59.7%) had rectosigmoid nodules and underwent bowel surgery. There was no significant difference in the accuracy of 3D-RWC-TVS and CTC in diagnosing the presence of rectosigmoid endometriotic nodules (p = 0.118), although CTC was more precise in diagnosing endometriosis located in the sigmoid (p = 0.016). 3D-RWC-TVS and CTC had similar precision in estimating the largest diameter of the main endometriotic nodule (p = 0.099) and, in patients undergoing segmental resection, the degree of the stenosis of the bowel lumen (p = 0.293). CTC was more accurate in estimating the distance between the lower margin of the intestinal nodule and the anal verge (p = 0.030) but was less tolerated than 3D-RWC-TVS (p < 0.001). (4) Conclusion: This was the first study comparing the performance of 3D-RWC-TVS and CTC in the diagnosis of rectosigmoid endometriosis. Both techniques allowed for the evaluation of the profile of the bowel lumen in a pseudoendoscopic fashion and had a similar performance for the diagnosis of rectosigmoid endometriosis, although CTC was more accurate in diagnosing and characterizing sigmoid nodules.

Abstract
PURPOSE To perform a systematic review and meta-analysis regarding the performance of CT for diagnosis of bowel endometriosis. MATERIALS AND METHODS Pubmed and EMBASE were systematically searched up to March 28, 2019. Diagnostic accuracy studies using CT for diagnosis of bowel endometriosis using laparoscopy followed by histopathology as the reference standard were included. Methodological quality of the included studies was evaluated using Quality Assessment of Diagnostic Accuracy Studies-2. Sensitivity and specificity were pooled using hierarchical summary receiver operating modelling. Meta-regression analysis was done to explore heterogeneity. RESULTS Twelve studies (1091 patients) were included. Pooled sensitivity and specificity were 0.92 (95% confidence interval [CI], 0.83-0.97) and 0.95 (95% CI, 0.88-0.98), respectively. Substantial heterogeneity was present: I2 = 92.38% for sensitivity and 89.09% for specificity. Deeks' asymmetry test suggested publication bias (p = 0.04). At meta-regression analysis, history of prior surgery for endometriosis was the only significant factor affecting heterogeneity (p < 0.01). Specifically, studies that included patients with such history demonstrated significantly greater specificity than studies that did not (0.95 [95% CI, 0.91-1.00] vs 0.75 [95% CI, 0.43-1.00]). CONCLUSIONS CT shows excellent performance in the diagnosis of bowel endometriosis. Due to small number of included studies and publication bias, further studies may be needed to validate these results.

Abstract
BACKGROUND The ureter is the second most common site affected by urinary tract endometriosis, after the bladder. Optimal strategies in the diagnosis and treatment of ureteral endometriosis (UE) are not yet well defined. OBJECTIVE AND RATIONALE The aim of this study was to systematically review evidence regarding the epidemiology, pathophysiology, diagnosis, medical and surgical treatment, impact on fertility and risk of malignant transformation of UE. SEARCH METHODS A systematic literature review, by searching the MEDLINE and PUBMED database until April 2018, was performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement and was registered in the PROSPERO registry (www.crd.york.ac.uk/PROSPERO CRD42017060065). A total of 67 articles were selected to be included in this review. OUTCOMES The involvement of the ureter by endometriosis is often asymptomatic or leads to non-specific symptoms. When the diagnosis is delayed, UE may lead to persistent hydronephrosis and eventually loss of renal function. Ultrasonography is the first-line technique for the assessment of UE; alternatively, magnetic resonance imaging provides an evaluation of ureteral type involvement. The surgical treatment of UE aims to relieve ureteral obstruction and avoid disease recurrence. It includes conservative ureterolysis or radical approaches, such as ureterectomy with end-to-end anastomosis or ureteroneocystostomy performed in relation to the type of ureteral involvement. Fertility and pregnancy outcomes are in line with those observed after surgical treatment of deep infiltrating endometriosis (DIE). Current evidence does not support the potential risk of malignant transformation of UE. WIDER IMPLICATIONS In this article, we review available evidence on ureteral endometriosis, providing a useful tool to guide physicians in the management of this disease. Diagnosis and management of UE remain a challenge. In relation to the degree of ureteral involvement and the association with other DIE implants, the surgical approach should be planned and carried out in an interdisciplinary collaboration between gynecologist and urologist.
