Abstract
BACKGROUND To evaluate the efficacy of the preoperative ultrasonographic sliding sign in predicting intra-abdominal adhesions. METHODS This was a single-center, double-blinded, prospective observational study undertaken from March and September 2021 on 110 patients with a history of previous abdominal surgery. All patients who were scheduled for laparoscopy underwent slide test in 5 zones of abdomen: right lower quadrant, left lower quadrant, previous operation site, vesicouterine pouch, and rectovaginal pouch. Adhesions were assessed by the same gynecologic surgeon using ultrasonography before the surgery and by gynecological surgeons during surgery, and by a third gynecologic surgeon to compare the preoperative slide test findings and laparoscopic findings after the surgery. RESULTS Seventy-three (66.4%) patients underwent laparoscopic surgery, and 37 (33.6%) patients underwent laparotomy. The mean age of patients was 46.9 ± 1.0 years. Sensitivity, specificity, and positive and negative predictive values of preoperative ultrasonography in predicting adhesions were 89.5%, 91.7%, 97.5%, and 71.0%, respectively. The accuracy of the slide test was calculated as 90.0%. It was found that as the total number of cesarean sections increased the estimates of vesicouterine adhesions and actual adhesions increased (P = .008). Also, the prediction of intra-abdominal adhesions and actual adhesions significantly increased as the total number of surgical operations increased (P = .002). CONCLUSIONS Intra-abdominal adhesions can be detected with the slide test, which is a non-invasive and well-tolerated procedure. Slide test can guide the physician before the elective operation in patients with previous abdominal surgery and may assist in counseling patients.

Diagnostic Accuracy of Transvaginal Sonography for Deeply Infiltrating Endometriosis and Pouch of Douglas Obliteration in the Presence or Absence of Ovarian Endometrioma. IRANIAN JOURNAL OF RADIOLOGY 2023.

Abstract
Background: Endometriosis is one of the most common gynecological diseases worldwide. Significant attention has been drawn to this multiorgan and often painful disorder. Objectives: This study aimed to examine the accuracy of transvaginal sonography (TVS) in the diagnosis of deeply infiltrating endometriosis (DIE) with respect to the presence or absence of ovarian endometrioma (OE). Patients and Methods: This cross-sectional study was performed on all patients undergoing TVS before gynecological laparoscopy. With pathological confirmation as the standard reference, the diagnostic accuracy of TVS for DIE and pouch of Douglas (POD) obliteration was compared with that of laparoscopy in the anterior and posterior pelvic compartments with respect to the presence or absence of OE. Agreement between TVS and laparoscopy was evaluated for each case, and Cohen’s kappa statistic was measured for each site of involvement. Moreover, sensitivity, specificity, negative and positive predictive values, and likelihood ratios of TVS were calculated, with laparoscopy as the reference test. Results: A total of 110 patients, with a mean age of 37.20 ± 7.16 years, were recruited in this study. The accuracy, sensitivity, and negative predictive value of TVS for the diagnosis of DIE and POD obliteration were estimated at 89.5%, 58.3%, and 88.9% in the anterior pelvic compartment and 93.3%, 92%, and 70.6% in the posterior pelvic compartment, respectively. Nevertheless, TVS showed lower sensitivity for detecting pelvic adhesions and peritoneal cysts compared to laparoscopy. The presence of OE did not significantly increase the accuracy of TVS for the diagnosis of DIE or POD obliteration (P > 0.05). Conclusion: The present study showed that TVS is an adequately accurate and non-invasive diagnostic tool for the detection and mapping of DIE and POD obliteration, regardless of the presence of OE. TVS may waive the need for exploratory laparoscopy in DIE or at least facilitate precise pre-procedural DIE mapping.

Abstract
PURPOSE To evaluate the relationship between gastrointestinal (GI) symptoms and transvaginal ultrasound (TVUS) findings suggestive of endometriosis. MATERIALS AND METHODS A prospective design. Women referred for a diagnostic ultrasound due to suspicion of endometriosis completed a Rome III and Pelvic Floor Distress Inventory (PFDI-20) questionnaire for clinical, GI symptoms, before undergoing TVUS. Endometriosis was diagnosed in the presence of endometriomas and/or deeply infiltrative endometriotic (DIE) lesions. Association between lesion sites and GI symptoms was evaluated by univariate and multivariate analysis. RESULTS The study included 241 women who presented with: dysmenorrhea (89.6 %), dyspareunia (76.3 %), chronic pelvic pain (77.2 %), dyschezia (66 %), hematochezia (15.4 %), subfertility (24.5 %). GI symptoms were present in 25.3-76.8 % and 5.4-55.6 % of Rome III and PFDI-20 questionnaire responses, respectively. TVUS findings were endometriomas (23.2 %), peritoneal adhesions (46.5 %), uterosacral ligament (26.7 %), retrocervical (11.2 %), rectosigmoid (11.2 %), intestinal (4.6 %), and bladder (0.8 %) involvement, and pouch of Douglas (POD) obliteration (15.4 %). There was a high prevalence of peritoneal adhesions, uterosacral ligament involvement, and rectosigmoid and intestinal nodules on TVUS in women with GI symptoms, up to Chi2 = 9.639 (p = 0.013) on univariate and Chi2 = 8.102 (p = 0.005) on multivariate analysis. CONCLUSION We observed an almost 10-fold increase in DIE lesions in women with GI symptoms. We suggest that the presence of GI symptoms should prompt a referral for endometriosis evaluation and performance of a dedicated TVUS before invasive gastrointestinal procedures.

Abstract
Endometriosis is a chronic systemic disease that can cause pain, infertility and reduced quality of life. Diagnosing endometriosis remains challenging, which yields diagnostic delays for patients. Research on diagnostic test accuracy in endometriosis can be difficult due to verification bias, as not all patients with endometriosis undergo definitive diagnostic testing. The purpose of this State-of-the-Art Review is to provide a comprehensive update on the strengths and limitations of the diagnostic modalities used in endometriosis and discuss the relevance of diagnostic test accuracy research pertaining to each. We performed a comprehensive literature review of the following methods: clinical assessment including history and physical examination, biomarkers, diagnostic imaging, surgical diagnosis and histopathology. Our review suggests that, although non-invasive diagnostic methods, such as clinical assessment, ultrasound and magnetic resonance imaging, do not yet qualify formally as replacement tests for surgery in diagnosing all subtypes of endometriosis, they are likely to be appropriate for advanced stages of endometriosis. We also demonstrate in our review that all methods have strengths and limitations, leading to our conclusion that there should not be a single gold-standard diagnostic method for endometriosis, but rather, multiple accepted diagnostic methods appropriate for different circumstances. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Endometriosis is a gynecological disease affecting about 10% of the female population. The multifactorial hormonal, inflammatory, genetic, mental and behavior pathogenesis can result in chronic pelvic pain, blooding disorders and infertility causing disruption of quality of life. Correct diagnosis of the extension and topography is substantial in defining the adequate therapeutic strategy. In an increasing proportion of the cases, endometriosis is being managed medically and para-medically; diagnostic or therapeutic surgery can often be avoided or delayed. Transvaginal sonography is considered being the first-line imaging method in the diagnosis of pelvic endometriosis. The paradigm shift from the belief that endometriosis only affects women of reproductive age has drawn attention to endometriosis in both premenarchal and postmenopausal patients. This review resumes the actually recommended ultrasound signs in the case of patients in menstrual age. Specific diagnostic approaches in adolescent and menopausal patients are highlighted.

JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2022; 41:1109-1113. [PMID: 34363423 DOI: 10.1002/jum.15800] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 06/29/2021] [Accepted: 07/04/2021] [Indexed: 06/13/2023]
Abstract
OBJECTIVES To determine whether ovarian fixation at transvaginal ultrasound (TVU) is a marker for a need for laparoscopic pelvic sidewall surgery (ie, ureterolysis or dissection of adhesions involving the pelvic sidewall). The relationship between ovarian immobility at TVU with respect to endometriosis staging using the revised American Fertility Society (r-AFS) classification was also evaluated. METHODS Retrospective diagnostic accuracy study was performed in a tertiary referral hospital and two private hospitals. Sixty-six women with pelvic pain underwent detailed TVU preoperatively followed by laparoscopic endometriosis surgery. TVU ovarian mobility findings (ie, mobile versus fixed ovary) were compared to surgical findings, the need for laparoscopic pelvic sidewall surgery and r-AFS score (I-IV). RESULTS Complete ultrasound and surgical data were available for 66 of 77 (86%) women. Twenty-six of 66 (40%) had isolated superficial peritoneal endometriosis, 15 of 66 (23%) had ovarian endometrioma (OE), 13 of 66 (20%) had pelvic deep endometriosis (DE). Twenty-seven of 66 (41%) had ovarian fixation at TVU. The accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of ovarian fixation at TVU for the prediction of need for laparoscopic pelvic sidewall surgery was 71%, 61%, 86%, 85%, and 62%, respectively (P = .0002). Ovarian fixation at TVU was significantly associated with the presence of ipsilateral OE, pouch of Douglas obliteration, pelvic DE nodules, and r-AFS stage III/IV (moderate/severe) endometriosis (all P-values <.05). CONCLUSIONS Ovarian fixation at TVU appears to be a marker for moderate/severe endometriosis and the need for laparoscopic pelvic sidewall surgery. This sign may be a valuable "red flag" for identifying women at increased risk of requiring an advanced laparoscopic surgeon, and in turn, improve surgical planning.

Abstract
Background Whilst some imaging signs of endometriosis are common and widely accepted as ‘typical’, a range of ‘subtle’ signs could be present in imaging studies, presenting an opportunity to the radiologist and the surgeon to aid the diagnosis and facilitate preoperative surgical planning. Objective To summarise and analyse the current information related to indirect and atypical signs of endometriosis by ultrasound (US) and magnetic resonance imaging (MRI). Methods Through the use of PubMed and Google scholar, we conducted a comprehensive review of available articles related to the diagnosis of indirect signs in transvaginal US and MRI. All abstracts were assessed and the studies were finally selected by two authors. Results Transvaginal US is a real time dynamic exploration, that can reach a sensitivity of 79-94% and specificity of 94%. It allows evaluation of normal sliding between structures in different compartments, searching for adhesions or fibrosis. MRI is an excellent tool that can reach a sensitivity of 94% and specificity of 77% and allows visualisation of the uterus, bowel loop deviation and peritoneal inclusion cysts. It also allows the categorisation and classification of ovarian cysts, rectovaginal and vesicovaginal septum obliteration, and small bowel endometriotic implants. Conclusion The use of an adequate mapping protocol with systematic evaluation and the reporting of direct and indirect signs of endometriosis is crucial for detailed and safe surgical planning.

Abstract
OBJECTIVE The aim of the study is to show the coexistence of the endometriomas with peritoneal and deep infiltrating endometriosis, as well as with the adhesions. Study design It's a randomized retrospective study. Patients treated for endometrioma at Academic Hospital Cologne Weyertal from January 2014 to October 2019 were included. In total there were 1054 patients. 310 medical records were chosen at random without a special selection and the data were analysed. RESULTS In our study, endometriomas were alone, which means without extraovarian endometriosis and/or adhesions, in only 2.3% of the cases. In the total population, 80.6% (250) of the patients had peritoneal endometriosis, 43.2% (134) of the patients had deep infiltrating endometriosis and 38% (118) of the patients had peritoneal and deep infiltrating endometriosis. In our analysis we found that in unilateral endometriomas there is no relationship between endometrioma size and adnexal adhesions. The risk of Douglas obliteration increases with the size of the endometriomas in unilateral endometriomas. In bilateral endometriomas, the risk of a complex adhesions is independent of the size of the endometriomas and relevantly higher than in unilateral endometriomas (Douglas obliteration 31.5% vs 16%, bilateral adnexal adhesions 45.2% vs 21.1%). Unilateral adnexal adhesions occurred in bilateral endometriomas only in 13.7%. CONCLUSION Endometriomas are the relevant problem in gynaecological practice. It must be taken into account here that endometriomas usually occur with peritoneal endometriosis and that surgical therapy may be useful. However, adhesions and DIE are to be expected with surgical treatment, which could make the operation more difficult. Especially in large and bilateral endometriomas, a high coexistence with extraovarian endometriomas and adhesions is observed. Therefore, surgery should be performed by an experienced surgeon.

Abstract
INTRODUCTION Endometriosis affects 10%-15% of women in reproductive age and may cause no-cyclic chronic pelvic pain, dysmenorrhea, dyspareunia, urinary tract symptoms, and it is frequently associated with infertility. The peak of incidence is between 24 and 29 years old and the clinical diagnosis of endometriosis is generally delayed by 6-7 years. Laparoscopy with surgical biopsies is the "gold standard" for the diagnosis of endometriosis, with histological verification of endometrial ectopic glands and/or stroma. However, nowadays two different non-invasive modalities are routinely used for a presumptive diagnosis: Transvaginal Ultrasound (TVUS) and Magnetic Resonance Imaging (MRI). EVIDENCE ACQUISITION A structured search using PubMed was performed starting from October 2020 and including all relevant original and review articles published since 2000. The search used the following key word combinations: "Endometriosis MRI" AND "DIE and MRI" (45); "MRI endometriosis and Pelvic Pain" OR "Endometriosis and MRI technical development" (296). Ultimately, 87 articles were deemed relevant and used as the literature basis of this review. EVIDENCE SYNTHESIS TVUS represents the first imaging approach for endometriosis showing a good diagnostic performance but it is highly operator dependent. MRI is a second level examination often used in complex cases indeterminate after TVUS and in pre-operative planning. MRI is considered the best imaging technique for mapping endometriosis since it provides a more reliable map of deep infiltrating endometriosis than physical examination and transvaginal ultrasound. We have analyzed and described the main forms of endometriosis: adnexal endometriosis, adenomyosis, peritoneal implants and deep infiltrating endometriosis, showing their appearance in the two imaging modalities. CONCLUSIONS Endometriosis is one of the most common gynecologic disorders correlated to chronic pelvic pain whose treatment is still today complex and controversial. In this context, MRI has become an important additional non-invasive tool to investigate cases of chronic pelvic pain related to deep infiltrating endometriosis (DIE) with or without neural involvement.

Abstract
Imaging of endometriosis and in particular deep endometriosis (DE) is crucial in the clinical management of women facing this debilitating condition. Transvaginal sonography (TVS) is the first-line imaging method and magnetic resonance imaging (MRI) may provide supplemental information. However, the delay in diagnosis of up to 10 years and more is of concern. This problem might be overcome by simple steps using imaging with emphasis on TVS and referral to tertiary care. Finally, TVS is crucial in mapping extent and location of disease in planning surgical therapy and counseling women regarding various therapeutic options. This review presents the available data on imaging of endometriosis with a focus on TVS and MRI for DE, adenomyosis, and ovarian endometriomas including endometriomas in pregnancy as well as the use of "soft markers." The review presents an approach that is in accordance with the International Deep Endometriosis Analysis (IDEA) group consensus statement.

Abstract
OBJECTIVES The aim of this study was to evaluate the use of ultrasound (US) soft markers as a first-line imaging tool to raise suspicion of rectosigmoid (RS) involvement in women suspected of having deep endometriosis. METHODS We included in this prospective observational study all patients with clinical suspicion of deep endometriosis who underwent diagnostic transvaginal US evaluation at our unit from January 2016 to February 2017. Several US soft markers were evaluated for prediction of RS involvement (presence of US signs of uterine adenomyosis, presence of an endometrioma, adhesion of the ovary to the uterus (reduced ovarian mobility), presence of 'kissing ovaries' (KO) and absence of the 'sliding sign'), using as the gold standard expert US examination for the presence of RS endometriosis. RESULTS Included were 333 patients with clinical suspicion of deep endometriosis. Of these, 106 had an US diagnosis of RS endometriosis by an expert. The only significant variables found in the prediction model were absence of the sliding sign (odds ratio (OR), 13.95; 95% CI, 7.7-25.3), presence of KO (OR, 22.5; 95% CI, 4.1-124.0) and the interaction between these two variables (OR, 0.03; 95% CI, 0.004-0.28). Regarding their interaction, RS endometriosis was present when KO was absent and the sliding sign was present in 10% (19/190) of cases, when both KO and the sliding sign were present in 71.4% (5/7) of cases, when both KO and the sliding sign were absent in 60.8% (76/125) of cases and when KO was present and the sliding sign was absent in 54.5% (6/11) of cases. Thus, when the sliding sign was absent and/or KO was present, transvaginal US showed a specificity of 75% (95% CI, 69-80%) and a sensitivity of 82% (95% CI, 73-88%). CONCLUSIONS US findings of absence of the sliding sign and/or presence of KO in patients with clinical suspicion of endometriosis should raise suspicion of RS involvement and indicate referral for expert US examination, with a low rate of false-negative diagnosis.

Abstract
OBJECTIVE To investigate the role of the transvaginal sonographic (TVS) sliding sign in predicting pelvic adhesions in women with previous abdominopelvic surgery. METHODS This was a multicenter, prospective, interventional, double-blind study of patients with a history of abdominopelvic surgery who were undergoing laparoscopy or laparotomy during the 6-month period from March to August 2016 in one of three academic obstetrics and gynecology departments. Prior to surgery, patients were examined by TVS to assess the vesicouterine pouch, uterus, ovaries and pouch of Douglas, using the TVS pelvic sliding sign. Ultrasound findings and medical and surgical data were recorded. We assessed the accuracy of the preoperative TVS sliding sign in the prediction of pelvic adhesions overall and in each compartment separately. RESULTS During the study period, complete TVS sliding sign and laparoscopic or laparotomic data were available for 107 women. Their mean age was 44.0 (95% CI, 41.6-46.4; range, 20-79) years. Their mean parity was 2.0 (95% CI, 1.7-2.3; range, 0-9) and the mean number of previous abdominal surgical procedures per patient was 1.3 (95% CI, 1.2-1.5; range, 1-4). Adhesions were noted in 27/107 (25.2%) patients. The TVS sliding sign had a sensitivity of 96.3% and specificity of 92.6% in predicting pelvic adhesions. There was a significant relationship between adhesions in each compartment and the TVS sliding sign (P < 0.05). CONCLUSIONS The TVS sliding sign is an effective means to detect preoperatively pelvic adhesions in patients with previous abdominopelvic surgery. Use of such a non-invasive and well-tolerated technique could help in the planning of laparoscopy or laparotomy and counseling of these patients. Copyright © 2017 ISUOG.

Abstract
OBJECTIVE To investigate spontaneous pregnancy rate (SPRs) of women with rectovaginal endometriosis (RV) with/without ovarian endometrioma (OMA) and treated with the use of expectant or surgical management. DESIGN Retrospective study. SETTING University hospital. PATIENT(S) The study included patients with RV with or without OMA who tried to conceive spontaneously for 1 year either without undergoing surgery (group E; n = 284) or after surgery (group S; n = 221). The study population was further divided into four subgroups: women with RV without OMA who directly tried to conceive (group eRV; n = 121) or tried to conceive after surgery (group sRV; n = 96), and women with RV with OMA who directly tried to conceive (group eOMA; n = 163) or tried to conceive after surgery (group sOMA; n = 125). INTERVENTIONS(S) Expectant or surgical management. MAIN OUTCOME MEASURE(S) Crude and cumulative SPRs. RESULT(S) At 1 year, crude and cumulative SPRs were lower in group E (17.3% and 23.8%, respectively) than in group S (35.7% and 39.5%). Similarly, crude and cumulative SPRs were lower in group eRV (24.8% and 30.6%) than in group sRV (42.7% and 45.7%, respectively) and in group eOMA (11.7% and 18.0%) than group sOMA (30.4% and 34.5%). At 1 year, crude and cumulative SPRs were higher in group eRV (24.8% and 30.6%) than in group eOMA (11.7% and 18.0%), and in group sRV (42.7% and 45.7%) than in group sOMA (30.4% and 34.5%). CONCLUSION(S) Crude and cumulative SPRs are lower in women treated with the use of expectant rather than surgical management. The presence of OMAs decreases SPRs independently from the treatment modality adopted.

J Assist Reprod Genet 2017; 34:765-774. [PMID: 28417349 PMCID: PMC5445055 DOI: 10.1007/s10815-017-0919-1] [Citation(s) in RCA: 42] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2017] [Accepted: 04/04/2017] [Indexed: 11/28/2022] Open
Abstract
PURPOSE The purpose of the study was to determine whether diagnosis of endometriosis or endometriosis with endometrioma influences in vitro fertilization (IVF) outcomes in an ethnically diverse population. METHODS Women undergoing a first IVF cycle (n = 717) between January 1, 2008 and December 31, 2009, at a university-affiliated infertility clinic, were retrospectively assessed for an endometriosis diagnosis. Differences in prevalence of endometriosis by ethnicity were determined, as well as differences in IVF success by ethnicity, with a focus on country of origin for Asian women. A multivariate model was generated to assess the relative contributions of country of origin and endometriosis to chance of clinical pregnancy with IVF. RESULTS Endometriosis was diagnosed in 9.5% of participants; 3.5% also received a diagnosis of endometrioma. Endometriosis prevalence in Asian women was significantly greater than in Caucasians (15.7 vs. 5.8%, p < 0.01). Women of Filipino (p < 0.01), Indian (p < 0.01), Japanese (p < 0.01), and Korean (p < 0.05) origin specifically were more likely to have endometriosis than Caucasian women, although there was no difference in endometrioma presence by race/ethnicity. Oocyte quantity, embryo quality, and fertilization rates did not relate to endometriosis. Clinical pregnancy rates were significantly lower for Asian women, specifically in Indian (p < 0.05), Japanese (p < 0.05), and Korean (p < 0.05) women, compared to Caucasian women, even after controlling for endometriosis status. CONCLUSIONS The prevalence of endometriosis appears to be higher in Filipino, Indian, Japanese, and Korean women presenting for IVF treatment than for Caucasian women; however, the discrepancy in IVF outcomes was conditionally independent of the presence of endometriosis. Future research should focus on improving pregnancy outcomes for Asian populations whether or not they are affected by endometriosis, specifically in the form of longitudinal studies where exposures can be captured prior to endometriosis diagnoses and infertility treatment.

Abstract
OBJECTIVES To examine the association between ovarian immobility and presence of endometriomas and assess the diagnostic accuracy of transvaginal sonographic (TVS) ovarian immobility in the detection of deep infiltrating endometriosis (DIE). METHODS This was a multicenter prospective observational study of women presenting with chronic pelvic pain from January 2009 to March 2015. Women with or without history of endometriosis who were scheduled to undergo laparoscopic surgery for endometriosis gave a detailed history and underwent specialized TVS in a tertiary referral unit prior to laparoscopy. During TVS, ovarian mobility and the presence of endometriomas were assessed. The relationship between TVS ovarian mobility, with or without endometriomas, and DIE was correlated with the gold standard, diagnosis of endometriosis at laparoscopy. RESULTS Included in the analysis were 265 women with preoperative TVS and laparoscopic outcomes. Ovarian immobility on TVS was significantly associated with presence of endometriomas at surgery, with a prevalence of 12.2%, 10.8% and 52.7% for fixation of the left ovary only, the right ovary only and bilateral ovaries, respectively, compared with 4.2%, 3.7% and 7.3% for normal ovaries. The sensitivity, specificity, positive (PPV) and negative (NPV) predictive values and positive and negative likelihood ratios of TVS ovarian immobility for diagnosis at surgery of immobility of ovaries with endometriomas in the left ovary only were 44.4%, 92.3%, 44.4%, 92.3%, 5.8, 0.6, in the right ovary only were 50.0%, 98.5%, 80.0%, 94.2%, 33.0, 0.5 and bilaterally were 74.4%, 68.6%, 72.5%, 70.6%, 2.4, 0.4, while those for diagnosis of immobility of normal ovaries were 25.0%, 87.9%, 8.3%, 96.4%, 2.1, 0.9 for left ovary only, 14.3%, 92.9%, 7.1%, 96.6%, 2.0, 0.9 for right ovary only and 35.7%, 97.2%, 50.0%, 95.0%, 12.6, 0.7 bilaterally, respectively (P < 0.05 except for normal left and right ovaries with P = 0.2 and 0.4, respectively). The sensitivity, specificity, PPV and NPV for performance of ovarian immobility in the prediction of DIE for all women were 58.3%, 74.1%, 60.6%, 72.2% and in the prediction of need for bowel surgery were 78.2%, 71.1%, 41.3%, 92.6%, respectively. CONCLUSIONS There is a significant association between ovarian immobility and the presence of endometriomas. Ovarian immobility as a sonographic 'soft marker' of DIE performs better in the presence of endometriomas compared with in normal ovaries. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Performance of ultrasound-based endometriosis staging system (UBESS) for predicting level of complexity of laparoscopic surgery for endometriosis. ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2016; 48:786-795. [PMID: 26764187 DOI: 10.1002/uog.15858] [Citation(s) in RCA: 58] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/05/2015] [Revised: 01/08/2016] [Accepted: 01/11/2016] [Indexed: 06/05/2023]
Abstract
OBJECTIVE To develop and assess the performance of a preoperative ultrasound-based endometriosis staging system (UBESS) to predict the level of complexity of laparoscopic surgery for endometriosis. METHODS This was a multicenter prospective and retrospective cohort study on consecutive women with suspected endometriosis who underwent laparoscopy between June 2009 and July 2013. Each woman underwent a systematic transvaginal ultrasound evaluation to assess the pelvis for different phenotypes of endometriosis, and the diagnostic performance of ultrasound for these different phenotypes was evaluated relative to the gold standard, laparoscopy. A three-stage preoperative UBESS was developed to assess the severity of pelvic endometriosis, based on the histological phenotypes of endometriosis, the anatomical locations of deep infiltrating endometriosis and their sonographic markers of local invasiveness. The three stages of UBESS (I-III) were then correlated with the three levels of complexity of laparoscopic surgery for endometriosis described by the Royal College of Obstetricians and Gynaecologists (Levels 1-3). The end-points were the diagnostic performance of UBESS to predict the level of complexity of laparoscopic surgery for endometriosis, i.e. UBESS stage I to predict Level-1 laparoscopic surgery, UBESS stage II to predict Level-2 laparoscopic surgery and UBESS stage III to predict Level-3 laparoscopic surgery. RESULTS The analysis included 192 women, with a mean ± SD age at diagnosis of endometriosis of 23.7 ± 9.3 years and a mean duration of symptoms prior to presentation of 42 months. Predominant reported locations of pelvic pain were left iliac fossa (32%), right iliac fossa (29.5%) and lower abdomen (61%) and predominant symptoms included dyspareunia (57.5%), dysmenorrhea (58.5%) and dyschezia (41.5%). The accuracy, sensitivity, specificity, positive and negative predictive values and positive and negative likelihood ratios of UBESS I for predicting a requirement for Level-1 laparoscopic surgery were: 87.5%, 83.3%, 91.7%, 90.9%, 84.6%, 10 and 0.182; those of UBESS II for predicting Level-2 surgery were: 87.0%, 73.7%, 90.3%, 65.1%, 93.3%, 7.6 and 0.292; and those of UBESS III for predicting Level-3 surgery were: 95.3%, 94.8%, 95.5%, 90.2%, 97.7%, 21.2 and 0.054, respectively. CONCLUSION UBESS could be utilized to predict the level of complexity of laparoscopic surgery for endometriosis. It has the potential to facilitate the triage of women with suspected endometriosis to the most appropriate surgical expertise required for laparoscopic endometriosis surgery. UBESS needs to be validated externally in multiple centers to assess its general applicability. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
The IDEA (International Deep Endometriosis Analysis group) statement is a consensus opinion on terms, definitions and measurements that may be used to describe the sonographic features of the different phenotypes of endometriosis. Currently, it is difficult to compare results between published studies because authors use different terms when describing the same structures and anatomical locations. We hope that the terms and definitions suggested herein will be adopted in centers around the world. This would result in consistent use of nomenclature when describing the ultrasound location and extent of endometriosis. We believe that the standardization of terminology will allow meaningful comparisons between future studies in women with an ultrasound diagnosis of endometriosis and should facilitate multicenter research.

Abstract
BACKGROUND About 10% of women of reproductive age suffer from endometriosis. Endometriosis is a costly chronic disease that causes pelvic pain and subfertility. Laparoscopy, the gold standard diagnostic test for endometriosis, is expensive and carries surgical risks. Currently, no non-invasive tests that can be used to accurately diagnose endometriosis are available in clinical practice. This is the first review of diagnostic test accuracy of imaging tests for endometriosis that uses Cochrane methods to provide an update on the rapidly expanding literature in this field. OBJECTIVES • To provide estimates of the diagnostic accuracy of imaging modalities for the diagnosis of pelvic endometriosis, ovarian endometriosis and deeply infiltrating endometriosis (DIE) versus surgical diagnosis as a reference standard.• To describe performance of imaging tests for mapping of deep endometriotic lesions in the pelvis at specific anatomical sites.Imaging tests were evaluated as replacement tests for diagnostic surgery and as triage tests that would assist decision making regarding diagnostic surgery for endometriosis. SEARCH METHODS We searched the following databases to 20 April 2015: MEDLINE, CENTRAL, EMBASE, CINAHL, PsycINFO, Web of Science, LILACS, OAIster, TRIP, ClinicalTrials.gov, MEDION, DARE, and PubMed. Searches were not restricted to a particular study design or language nor to specific publication dates. The search strategy incorporated words in the title, abstracts, text words across the record and medical subject headings (MeSH). SELECTION CRITERIA We considered published peer-reviewed cross-sectional studies and randomised controlled trials of any size that included prospectively recruited women of reproductive age suspected of having one or more of the following target conditions: endometrioma, pelvic endometriosis, DIE or endometriotic lesions at specific intrapelvic anatomical locations. We included studies that compared the diagnostic test accuracy of one or more imaging modalities versus findings of surgical visualisation of endometriotic lesions. DATA COLLECTION AND ANALYSIS Two review authors independently collected and performed a quality assessment of data from each study. For each imaging test, data were classified as positive or negative for surgical detection of endometriosis, and sensitivity and specificity estimates were calculated. If two or more tests were evaluated in the same cohort, each was considered as a separate data set. We used the bivariate model to obtain pooled estimates of sensitivity and specificity when sufficient data sets were available. Predetermined criteria for a clinically useful imaging test to replace diagnostic surgery included sensitivity ≥ 94% and specificity ≥ 79%. Criteria for triage tests were set at sensitivity ≥ 95% and specificity ≥ 50%, ruling out the diagnosis with a negative result (SnNout test - if sensitivity is high, a negative test rules out pathology) or at sensitivity ≥ 50% with specificity ≥ 95%, ruling in the diagnosis with a positive result (SpPin test - if specificity is high, a positive test rules in pathology). MAIN RESULTS We included 49 studies involving 4807 women: 13 studies evaluated pelvic endometriosis, 10 endometriomas and 15 DIE, and 33 studies addressed endometriosis at specific anatomical sites. Most studies were of poor methodological quality. The most studied modalities were transvaginal ultrasound (TVUS) and magnetic resonance imaging (MRI), with outcome measures commonly demonstrating diversity in diagnostic estimates; however, sources of heterogeneity could not be reliably determined. No imaging test met the criteria for a replacement or triage test for detecting pelvic endometriosis, albeit TVUS approached the criteria for a SpPin triage test. For endometrioma, TVUS (eight studies, 765 participants; sensitivity 0.93 (95% confidence interval (CI) 0.87, 0.99), specificity 0.96 (95% CI 0.92, 0.99)) qualified as a SpPin triage test and approached the criteria for a replacement and SnNout triage test, whereas MRI (three studies, 179 participants; sensitivity 0.95 (95% CI 0.90, 1.00), specificity 0.91 (95% CI 0.86, 0.97)) met the criteria for a replacement and SnNout triage test and approached the criteria for a SpPin test. For DIE, TVUS (nine studies, 12 data sets, 934 participants; sensitivity 0.79 (95% CI 0.69, 0.89) and specificity 0.94 (95% CI 0.88, 1.00)) approached the criteria for a SpPin triage test, and MRI (six studies, seven data sets, 266 participants; sensitivity 0.94 (95% CI 0.90, 0.97), specificity 0.77 (95% CI 0.44, 1.00)) approached the criteria for a replacement and SnNout triage test. Other imaging tests assessed in small individual studies could not be statistically evaluated.TVUS met the criteria for a SpPin triage test in mapping DIE to uterosacral ligaments, rectovaginal septum, vaginal wall, pouch of Douglas (POD) and rectosigmoid. MRI met the criteria for a SpPin triage test for POD and vaginal and rectosigmoid endometriosis. Transrectal ultrasonography (TRUS) might qualify as a SpPin triage test for rectosigmoid involvement but could not be adequately assessed for other anatomical sites because heterogeneous data were scant. Multi-detector computerised tomography enema (MDCT-e) displayed the highest diagnostic performance for rectosigmoid and other bowel endometriosis and met the criteria for both SpPin and SnNout triage tests, but studies were too few to provide meaningful results.Diagnostic accuracies were higher for TVUS with bowel preparation (TVUS-BP) and rectal water contrast (RWC-TVS) and for 3.0TMRI than for conventional methods, although the paucity of studies precluded statistical evaluation. AUTHORS' CONCLUSIONS None of the evaluated imaging modalities were able to detect overall pelvic endometriosis with enough accuracy that they would be suggested to replace surgery. Specifically for endometrioma, TVUS qualified as a SpPin triage test. MRI displayed sufficient accuracy to suggest utility as a replacement test, but the data were too scant to permit meaningful conclusions. TVUS could be used clinically to identify additional anatomical sites of DIE compared with MRI, thus facilitating preoperative planning. Rectosigmoid endometriosis was the only site that could be accurately mapped by using TVUS, TRUS, MRI or MDCT-e. Studies evaluating recent advances in imaging modalities such as TVUS-BP, RWC-TVS, 3.0TMRI and MDCT-e were observed to have high diagnostic accuracies but were too few to allow prudent evaluation of their diagnostic role. In view of the low quality of most of the included studies, the findings of this review should be interpreted with caution. Future well-designed diagnostic studies undertaken to compare imaging tests for diagnostic test accuracy and costs are recommended.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2015; 46:109-117. [PMID: 25358293 DOI: 10.1002/uog.14712] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/18/2014] [Revised: 09/08/2014] [Accepted: 10/21/2014] [Indexed: 06/04/2023]
Abstract
OBJECTIVE Magnetic resonance imaging (MRI) and ultrasound scanning complement each other in screening for and diagnosis of endometriosis. Fusion imaging, also known as real-time virtual sonography, is a new technique that uses magnetic navigation and computer software for the synchronized display of real-time ultrasound and multiplanar reconstructed MR images. Our aim was to evaluate the feasibility and ability of fusion imaging to assess the main anatomical sites of deep infiltrating endometriosis (DIE) in patients with suspected active endometriosis. METHODS This prospective study was conducted over a 1-month period in patients referred to a trained radiologist for an ultrasound-based evaluation for endometriosis. Patients with a prior pelvic MRI examination within the past year were offered fusion imaging, in addition to the standard evaluation. All MRI examinations were performed on a 1.5-T MRI machine equipped with a body phased-array coil. The MRI protocol included acquisition of at least two fast spin-echo T2-weighted orthogonal planes. The Digital Imaging Communications in Medicine dataset acquired at the time of the MRI examination was loaded into the fusion system and displayed together with the ultrasound image on the same monitor. The sets of images were then synchronized manually using one plane and one anatomical reference point. The ability of this combined image to identify and assess the main anatomical sites of pelvic endometriosis (uterosacral ligaments, posterior vaginal fornix, rectum, ureters and bladder) was evaluated and compared with that of standard B-mode ultrasound and MRI. RESULTS Over the study period, 100 patients were referred for ultrasound examination because of endometriosis. Among them were 20 patients (median age, 35 (range, 27-49) years) who had undergone MRI examination within the past year, with a median (range) time interval between MRI and ultrasound examination of 171 (1-350) days. All 20 patients consented to undergo additional evaluation by fusion imaging. However, in three (15%) cases, fusion imaging was not technically possible because of changes since the initial MRI examination resulting from either interval surgery (n = 2; 10%) or pregnancy (n = 1; 5%). Data acquisition, matching and fusion imaging were performed in under 10 min in each of the other 17 cases. The overall ability of each technique to identify and assess the main anatomical landmarks of endometriosis was as follows: uterosacral ligaments: ultrasound, 88% (30/34); MRI, 100% (34/34); fusion imaging, 100% (34/34); posterior vaginal fornix: ultrasound, 88% (30/34); MRI, 100% (34/34); fusion imaging, 100% (34/34); rectum: ultrasound, 100% (17/17); MRI, 82.3% (14/17); fusion imaging, 100% (17/17); ureters: ultrasound, 0%; MRI, 100% (34/34); fusion imaging, 100% (34/34); and bladder: ultrasound, 100%; MRI, 100%; fusion imaging, 100%. CONCLUSION Fusion imaging is feasible for the assessment of endometriotic lesions. Because it combines information from both ultrasound and MRI techniques, fusion imaging allows better identification of the main anatomical sites of DIE and has the potential to improve the performance of ultrasound and MRI examination.

Abstract
OBJECTIVES To investigate the prevalence and location of pelvic adhesions in women with a history of Cesarean section and to identify risk factors for their formation and symptoms associated with their presence. METHODS This was a prospective observational study of women in whom one or more Cesarean sections had been performed > 12 months previously and who attended for a gynecological ultrasound examination. In all women, both transvaginal and transabdominal scans were performed in order to identify the presence of pelvic adhesions. Medical and surgical history was recorded and a structured questionnaire was used to enquire about any history of pelvic pain and urinary symptoms. RESULTS A total of 308 women were recruited into the study. On ultrasound examination, 139 (45.1% (95% CI, 39.7-50.7%)) women showed evidence of adhesions within the pelvis. Adhesions in the vesicouterine pouch were the most common and were found in a total of 79 (25.6% (95% CI, 20.7-30.5%)) women. In women with a history of no surgery other than Cesarean section(s) (n = 220), an increasing number of Cesarean sections (odds ratio (OR) 3.4 (95% CI, 2.1-5.5)) and a postoperative wound infection (OR 11.7 (95% CI, 3.5-39.5)) increased the likelihood of adhesions developing in the anterior pelvic compartment. There was a significant association between the presence of anterior compartment adhesions and chronic pelvic pain. Multivariable logistic regression analysis identified anterior abdominal wall adhesions (OR 2.4 (95% CI, 1.0-5.9)) and any adhesions present on ultrasound scan (OR 2.6 (95% CI, 1.2-5.7)) as independent predictors of chronic pelvic pain. CONCLUSIONS Pelvic adhesions are present in more than a third of women with a history of Cesarean section and they are associated with chronic pelvic pain.

Abstract
Background Endometriosis is a common condition which causes pain and reduced fertility. Treatment can be difficult, especially for severe disease, and an accurate preoperative assessment would greatly help in the managment of these patients. The objective of this study is to assess the accuracy of pre-operative transvaginal ultrasound scanning (TVS) in identifying the specific features of pelvic endometriosis and pelvic adhesions in comparison with laparoscopy. Methods Consecutive women with clinically suspected or proven pelvic endometriosis, who were booked for laparoscopy, were invited to join the study. They all underwent a systematic transvaginal ultrasound examination in order to identify discrete endometriotic lesions and pelvic adhesions. The accuracy of ultrasound diagnosis was determined by comparing pre-operative ultrasound to laparoscopy findings. Results 198 women who underwent preoperative TVS and laparoscopy were included in the final analysis. At laparoscopy 126/198 (63.6%) women had evidence of pelvic endometriosis. 28/126 (22.8%) of them had endometriosis in a single location whilst the remaining 98/126 (77.2%) had endometriosis in two or more locations. Positive likelihood ratios (LR+) for the ultrasound diagnosis of ovarian endometriomas, moderate or severe ovarian adhesions, pouch of Douglas adhesions, and bladder deeply infiltrating endometriosis (DIE), recto-sigmoid colon DIE, rectovaginal DIE, uterovesical fold DIE and uterosacral ligament DIE were >10, whilst for pelvic side wall DIE and any ovarian adhesions the + LH was 8.421 and 9.81 respectively. The negative likelihood ratio (LR-) was: <0.1 for bladder DIE; 0.1-0.2 for ovarian endometriomas, moderate or severe ovarian adhesions, and pouch of Douglas adhesions; 0.5-1 for rectovaginal, uterovesical fold, pelvic side wall and uterosacral ligament DIE. The accuracy of TVS for the diagnosis of both total number of endometriotic lesions and DIE lesions significantly improved with increasing total number of lesions. Conclusions Our study has shown that the TVS diagnosis of endometriotic lesion is very specific and false positive results are rare. Negative findings are less reliable and women with significant symptoms may still benefit from further investigation even if TVS findings are normal. The accuracy of ultrasound diagnosis is significantly affected by the location and number of endometriotic lesions.

Abstract
OBJECTIVE To evaluate preoperative real-time dynamic transvaginal sonography (TVS) in the prediction of pouch of Douglas (POD) obliteration in women undergoing laparoscopy for suspected endometriosis. METHODS This was a multicenter prospective observational study undertaken from January 2009 to November 2011. All women with symptoms suggestive of endometriosis who were scheduled for laparoscopy underwent detailed preoperative TVS, in particular to ascertain whether the POD was obliterated. POD obliteration was assessed using a real-time TVS technique called the 'sliding sign'. Preoperative TVS sliding sign findings were then compared to gold standard laparoscopic POD findings. RESULTS One hundred consecutive women with preoperative TVS and laparoscopic outcomes were included in the final analysis. Mean age was 32.8 years and mean age at diagnosis of endometriosis was 27.4 years. At laparoscopy, 84/100 (84%) were found to have some form of endometriosis (73% peritoneal endometriosis, 35% ovarian endometrioma(s), 33% deep infiltrating endometriosis). At laparoscopy, 30/100 (30%) had an obliterated POD and 19/30 (63.3%) of these women also had evidence of bowel endometriosis. The sonographic sliding sign technique had an accuracy of 93.0%, sensitivity of 83.3%, specificity of 97.1%, positive predictive value of 92.6%, negative predictive value of 93.2%, positive likelihood ratio of 29.2 and negative likelihood ratio of 0.17 in the prediction of POD obliteration (P = 1.8E-16). CONCLUSIONS Preoperative real-time dynamic TVS evaluation using the sliding sign seems to establish with a high degree of certainty whether the POD is obliterated. Given the increased risk of deep infiltrating endometriosis in women with POD obliteration, the TVS sliding sign technique may also be useful in the identification of women who may be at a higher risk for bowel endometriosis.

Abstract
Endometriosis is a common multifocal gynecologic disease that manifests during the reproductive years, often causing chronic pelvic pain and infertility. It may occur as invasive peritoneal fibrotic nodules and adhesions or as ovarian cysts with hemorrhagic content. Although findings at physical examination may be suggestive, imaging is necessary for definitive diagnosis, patient counseling, and treatment planning. The imaging techniques that are most useful for preoperative disease mapping are transvaginal ultrasonography (US) after bowel preparation, and magnetic resonance (MR) imaging. Initial transvaginal US is a reliable technique for detecting rectosigmoid endometriotic lesions. MR imaging is indicated as a complementary examination in complex cases of endometriosis with extensive adhesions and ureteral involvement. Peritoneal endometriotic implants are typically hypoechoic on transvaginal US images and demonstrate low signal intensity on T2-weighted MR images. Endometriotic implants most commonly are found in retrocervical and rectosigmoid sites, followed by the vagina, bladder, and ureters. Cysts with low-level internal echoes and echogenic peripheral foci at transvaginal US are suggestive of endometriomas. MR imaging has high specificity for identifying endometriomas, which are characterized by high signal intensity on T1-weighted images and low signal intensity on T2-weighted images. Correlation of the radiologic imaging features of endometriotic lesions with their laparoscopic appearances may help improve individual proficiency in the radiologic diagnosis of endometriosis.
