Lou Y, Li D, Yu J, Chen J, Jin X. Diagnostic performance of transvaginal sonography vs. magnetic resonance imaging for rectovaginal septum deep infiltrating endometriosis: a head-to-head comparative meta-analysis. Clin Radiol 2024:S0009-9260(24)00242-3. [PMID: 38797608 DOI: 10.1016/j.crad.2024.05.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2024] [Revised: 04/12/2024] [Accepted: 05/03/2024] [Indexed: 05/29/2024]
Abstract
AIM We aimed to compare the diagnostic performance of transvaginal sonography (TVS) versus magnetic resonance imaging (MRI) in identifying deep infiltrating endometriosis (DIE) in the rectovaginal septum (RVS) of affected patients. MATERIALS AND METHODS An extensive search was conducted in the PubMed, Embase databases to identify available publications up to November 2023. Studies evaluating the diagnostic perfor-mance of TVS and MRI for DIE in patients with rectovaginal septum involvement were all included. Sensitivity and specificity analyses employed the DerSi-monian and Laird method, complemented by the Freeman-Tukey double arc-sine trans-formation. Additionally, the study quality was rigorously evaluated using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) method. RESULTS The meta-analysis encompassed 8 articles with a total of 721 patients. It revealed that the overall sensitivity of TVS was 0.51 (95% CI: 0.31-0.72), contrasted with 0.74 (95% CI: 0.66-0.82) for MRI. This finding suggests a higher sensitivity of MRI compared to TVS (P=0.04). Conversely, the overall specificity was 0.97 (95%CI: 0.94-1.00) for TVS and 0.93 (95% CI: 0.84-0.99) for MRI, indicating a comparable level of specificity between the two modalities (P=0.22). CONCLUSION Our meta-analysis reveals that MRI exhibits higher sensitivity and comparable specificity to TVS in patients with DIE of the RVS. However, the limited number of articles included may affect the evidence of these results. Therefore, further d number of articles included may affect the evidence of these results. Therefore, further research with larger sample sizes and prospective designs is essential to validate these findings.

Abstract
BACKGROUND The diagnostic ability of endoscopic ultrasound (EUS) for intestinal infiltration by pelvic masses has aroused considerable interest in many oncological settings. This study aimed to evaluate the effectiveness of EUS in predicting colorectal invasion in patients with pelvic masses and compare its accuracy with that of other imaging methods, namely pelvic MRI and abdominal computed tomography (CT), in predicting intestinal involvement in patients with histologically confirmed colorectal invasion. METHODS A hundred and eighty-four female patients with histologically confirmed benign or malignant pelvic masses were enrolled in a retrospective-prospective study. All patients underwent EUS, pelvic MRI, and one or more of abdominal CT, transvaginal sonography, and colonoscopy examinations before surgery. The surgical and pathological results were used as the gold standard to evaluate the diagnostic accuracy of EUS for colorectal invasion of pelvic masses. RESULTS This study included 184 patients who underwent surgery, with the time between EUS and surgery ranging from 1 to 309 (mean, 13.2) days. The diagnostic sensitivity, specificity, positive predictive value, and negative predictive value of EUS for benign and malignant pelvic masses infiltrating the intestine were 83.3, 97.8, 99.1, and 66.2%, respectively. The overall diagnostic accuracy was 87.0%. CONCLUSIONS EUS is a simple, noninvasive, reliable, and accurate technique for the preoperative diagnosis of pelvic masses infiltrating the intestine. The authors recommend the use of this technology by gynecologists, as well as its incorporation into the preoperative diagnostic process to determine the most suitable surgical method. This would help in avoiding unexpected situations and unnecessary resource wastage during surgery.

Abstract
Deep infiltrating endometriosis (DIE) is characterized by the presence of endometrial tissue outside the uterine cavity that infiltrates at least 5-mm deep below the peritoneal layer. Imagining examinations are the first-choice methods to detect DIE. The aim of this study is to assess whether rectal water contrast transvaginal sonography (RWC-TVS) can be a useful tool for the estimation of the size of deep bowel endometriotic nodules. This retrospective study includes 31 patients subjected to RWC-TVS who underwent surgery due to deep bowel endometriosis between January 2021 and December 2022. Nodule dimensions measured via ultrasound were compared to those of histopathological samples taken after surgery. In total, 52% of patients had endometriosis limited only to the intestines, 19% had endometriotic nodules located at uterosacral ligaments and posterior vaginal fornix, 6% at the anterior compartment, and 13% at a different location. Additionally, 6% of patients had nodules at more than two locations. In all but one case, the intestinal nodules could be seen on RWC-TVS images. The largest nodule dimension measured via RWC-TVS and the size of the equivalent histopathological sample correlated (R = 0.406, p = 0.03). Thus, RWC-TVS allows for the detection of DIE and moderate estimation of the nodule sizes and should be practiced during a diagnostic process.

Abstract
Benign and malignant pelvic masses with or without intestinal invasion are common in women of childbearing age. Patients may have nonspecific symptoms and signs or experience no symptoms. Laparoscopic resection of pelvic masses is currently the mainstream treatment; therefore, accurate preoperative evaluation is not only essential for patients suspected of having intestinal invasion, but also extremely important for the selection of follow-up treatment. Procedures, including endoscopic ultrasonography (EUS), pelvic magnetic resonance imaging, abdominal computed tomography, vaginal ultrasonography, barium enema, and colonoscopy, aid in determining the presence, depth, and histology of the disease. In particular, the wide application and continuous developments in EUS techniques have improved the diagnostic accuracy for intestinal subepithelial and peripheral organ lesions. This article reviewed the clinical value of EUS in the diagnosis of benign and malignant pelvic masses with bowel involvement.

Abstract
STUDY QUESTION Is there an ideal imaging modality for the detection of uterosacral ligaments/torus uterinus (USL), rectovaginal septum (RVS) and vaginal deep endometriosis (DE) in women with a clinical history of endometriosis? SUMMARY ANSWER The sensitivity for the detection of USL, RVS and vaginal DE using MRI seems to be better than transvaginal ultrasonography (TVS), whilst the specificity of both were excellent. WHAT IS KNOWN ALREADY The surgical management of women with DE can be complex and requires advanced laparoscopic skills with maximal cytoreduction being vital at the first procedure to provide the greatest symptomatic benefit. Owing to a correlation of TVS findings with surgical findings, preoperative imaging has been used to adequately consent women and plan the appropriate surgery. However, until publication of the consensus statement by the International Deep Endometriosis Analysis Group in 2016, there were significant variations within the terms and definitions used to describe DE in the pelvis. STUDY DESIGN SIZE DURATION A systematic review and meta-analysis was conducted using Embase, Google Scholar, Medline, PubMed and Scopus to identify studies published from inception to May 2020, of which only those from 2010 were included owing to the increased proficiency of the sonographers and advancements in technology. PARTICIPANTS/MATERIALS SETTING METHODS All prospective studies that preoperatively assessed any imaging modality for the detection of DE in the USL, RVS and vagina and correlated with the reference standard of surgical data were considered eligible. Study eligibility was restricted to those including a minimum of 10 unaffected and 10 affected participants. MAIN RESULTS AND THE ROLE OF CHANCE There were 1977 references identified from which 10 studies (n = 1188) were included in the final analysis. For the detection of USL DE, the overall pooled sensitivity and specificity for all TVS techniques were 60% (95% CI 32-82%) and 95% (95% CI 90-98%), respectively, and for all MRI techniques were 81% (95% CI 66-90%) and 83% (95% CI 62-94%), respectively. For the detection of RVS DE, the overall pooled sensitivity and specificity for all TVS techniques were 57% (95% CI 30-80%) and 100% (95% CI 92-100%), respectively. For the detection of vaginal DE, the overall pooled sensitivity and specificity for all TVS techniques were 52% (95% CI 29-74%) and 98% (95% CI 95-99%), respectively, and for all MRI techniques were 64% (95% CI 40-83%) and 98% (96% CI 93-99%). Pooled analyses were not possible for other imaging modalities. LIMITATIONS REASONS FOR CAUTION There was a low quality of evidence given the high risk of bias and heterogeneity in the included studies. There are also potential biases secondary to the risk of misdiagnosis at surgery owing to a lack of either histopathological findings or expertise, coupled with the surgeons not being blinded. Furthermore, the varying surgical experience and the lack of clarity regarding complete surgical clearance, thereby also contributing to the lack of histopathology, could also explain the wide range of pre-test probability of disease. WIDER IMPLICATIONS OF THE FINDINGS MRI outperformed TVS for the per-operative diagnosis of USL, RVS and vaginal DE with higher sensitivities, although the specificities for both were excellent. There were improved results with other imaging modalities, such as rectal endoscopy-sonography, as well as the addition of bowel preparation or ultrasound gel to either TVS or MRI, although these are based on individual studies. STUDY FUNDING/COMPETING INTERESTS No funding was received for this study.

Abstract
Endometriosis refers to the implantation and proliferation of endometrial tissue outside the uterus. Small bowel endometriosis is an uncommon location for endometrial deposits and when present, it can pose diagnostic difficulty. Here, we present a case of a 50-year-old female with small bowel endometriosis who suffered from recurrent attacks of colicky abdominal pain for few months. Her cross-sectional investigations remained largely inconclusive. Ultimately, she underwent diagnostic laparoscopy which was diagnostic and therapeutic.

Abstract
OBJECTIVE To review the diagnostic accuracy and determine the optimum imaging modality for the detection of bladder deep endometriosis (DE) in women with a clinical suspicion of endometriosis. METHODS A systematic review of studies published from inception to May 2020 using Embase, Google Scholar, Medline, PubMed and Scopus. Prospective studies, which pre-operatively assessed any imaging modality for the presence of bladder DE, and correlated with the gold standard surgical data as a reference were included. The QUADAS-2 tool was used to assess quality. This review was prospectively registered with PROSPERO (CRD42017059872). RESULTS Of the 1,977 references identified, 8 studies (n = 1,052) were included in the analysis. The overall pooled sensitivity and specificity, from which the likelihood ratio of a positive test (LR+), likelihood ratio of a negative test (LR-) and diagnostic odds ratio (DOR) were calculated, for all transvaginal ultrasonography (TVS) techniques were 55 % (95 % CI 28-79%), 99 % (95 % CI 98-100%), 54.5 (95 % CI 18.9-157.4), 0.46 (95 % CI 0.25 - 0.85) and 119 (95 % CI 24-577), and for only two-dimensional (2D) TVS 53 % (95 % CI 23-82%), 99 % (96 % CI 97-100%), 48.8 (95 % CI 13.1-181.4), 0.47 (95 % CI 0.23 - 0.98), and 104 (95 % CI 15-711), respectively. Meta-analyses of the other modalities, namely magnetic resonance imaging (MRI) and transrectal endoscopic sonography (RES), were not possible due to the limited number of studies. There was significant heterogeneity and the studies were considered poor methodologically according to the QUADAS-2 tool. CONCLUSIONS Whilst the sensitivity of TVS was limited, the specificity was excellent. Given that there is a paucity of literature for other imaging modalities, until more studies are performed, TVS should be considered as the first-line tool given it is the only modality with sufficient evidence.

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
BACKGROUND Rectosigmoid endometriosis is an underdiagnosed disease responsible for abdominal pain, transit disorders and rectal bleeding. Two surgical approaches, rectosigmoid bowel resection (segmental or patch) or intramuscular layer dissection (shaving), are available.
AIM To assess whether the lesion features observed via preoperative rectosigmoid endoscopic ultrasonography (RS-EUS) might predict the need for bowel resection.
METHODS This multicentric retrospective study was conducted on patients with rectosigmoid endometriosis who underwent a curative surgical procedure, evaluated by RS-EUS performed by two trained operators, between January 2012 and March 2018. A univariate statistical analysis was performed on nodules’ RS-EUS features (thickness, width, infiltration of the submucosae, presence of a bump into the digestive lumen and presence of multiple rectosigmoid localizations). A multivariate logistic regression was then performed on the significant results.
RESULTS Of the 367 patients, 73 patients with rectosigmoid endometriosis were evaluated by RS-EUS and underwent rectosigmoid surgery. After the univariate analysis was completed, thickness, width and infiltration of the submucosae were identified as potential predictive factors for bowel resection. In a multivariate logistic regression model, only thickness appeared to be a significant [odds ratio (OR) = 1.49, 95% confidence interval (CI): 1.04-2.12, P = 0.028] predictive factor for bowel resection. Receiver operating characteristic analysis performed showed that a thickness over 5.20 mm might be used as cut-off with a sensitivity of 76%, a specificity of 81%, and an area under carve = 0.82. The cut-off values for 100% sensitivity and 100% specificity were 0.90 mm and 10.00 mm, respectively. A trend concerning width to predict the need for resection was also observed (OR 1.12, 95%CI: 1.00-1.26, P = 0.054)
CONCLUSION The presence of a rectosigmoid nodule of endometriosis greater than 5.20 mm thick on RS-EUS might predict the need for bowel resection.

Since the presence of intestinal endometriosis cannot be reliably established by physical examination or the evaluation of intestinal symptoms, imaging techniques are required for the diagnosis of bowel endometriosis. This review evaluates the techniques available for the diagnosis of intestinal endometriosis based on a search of the Medline database and Embase up to February 2010. Several studies have proved that radiological techniques (double contrast barium enema, magnetic resonance imaging, and multidetector computerized tomography enteroclysis) are able to accurately diagnose intestinal endometriosis. Magnetic resonance imaging has the advantage of determining the presence of deep endometriotic lesions in other pelvic locations. Rectal endoscopic ultrasonography can precisely determine the presence of bowel endometriosis but its use is limited by the availability of the equipment required to carry out the exam. Over the last five years, several studies have proved that transvaginal ultrasonography is accurate in the diagnosis of rectosigmoid endometriosis; in addition, this exam is well tolerated by patients and is inexpensive. Therefore, transvaginal ultrasonography should be the first-line investigation in patients with suspected intestinal endometriosis.

Magnetic Resonance Colonography May Predict the Need for Bowel Resection in Colorectal Endometriosis. BIOMED RESEARCH INTERNATIONAL 2017; 2017:5981217. [PMID: 29147655 PMCID: PMC5632851 DOI: 10.1155/2017/5981217] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/02/2017] [Revised: 07/26/2017] [Accepted: 08/02/2017] [Indexed: 02/08/2023]
Abstract
Purpose To define if MRI findings in patients with deep pelvic endometriosis (DPE) may be predictive for the need of bowel resection. Material and Methods A retrospective survey of 196 pelvic MRIs of women who received laparoscopic procedures for DPE was carried out. A pelvic MRI was performed in all patients: it consisted in T2w-TSE sequences in axial, sagittal, and coronal planes and T1w and THRIVE sequences in the axial plane; the exam was completed by MR-Colonography. Intestinal lesions were measured in short and long axis and the degree of stenosis was established. A multivariate logistic regression was used to identify the predictors of intestinal resection. Results 57/196 patients received an intestinal resection. Multivariate logistic regression demonstrated a predictive value of short axis (Odds-Ratio = 2.29, p = 0.011) and stenosis (Odds-Ratio = 1.20, p = 0.003). ROC analysis showed that a cut-off value of 11 mm for the short axis and 30% for the stenosis may correctly classify, respectively, 96,94% (sensitivity 92,9% and specificity 98,56%) and 97,96% (sensitivity 94,74% and specificity 99,3%) of the cases. Conclusion The presence of an endometriotic rectal nodule > 11 mm in short axis causing a stenosis > 30% in pelvic MRI reliably predicts the need of a rectal resection.

Abstract
BACKGROUND Fusion imaging is an accepted method in abdominal imaging allowing a simultaneous display of reference imaging with a live ultrasound (US) investigation. For prostate cancer, promising results have been published for endorectal US (ERUS)-guided biopsy of suspicious lesions in magnetic resonance imaging (MRI). To our knowledge, no other indication for the fusion of ERUS with MRI has been reported so far. METHODS We report on three patients scheduled for ERUS due to anorectal fistulae after treatment (n = 2) or rectal carcinoma (n = 1), which were scheduled for real-time virtual onography (RVS), a method for the fusion of MRI imaging with US. RESULTS In all patients, RVS was successful. The course of the fistulae could be defined and the success of the treatment could be confirmed. In the patient with rectal carcinoma, the lymph nodes suspicious in MRI could be identified. CONCLUSIONS MRI/ERUS fusion has the potential for follow-up of anorectal fistulae and abscesses, and staging of anal and rectal tumors.

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.

Abstract
Objectives: The aim of this study was to perform saline sonovaginography (SVG) in women with suspected rectovaginal endometriosis (RVE) in order to establish the thickness of the rectovaginal septum (RVS) in this population and to predict the presence or absence of RVE. Methods: Prospective observational pilot study. Women undergoing laparoscopy for possible endometriosis on the basis of history or clinical examination were offered to participate in the study. All women underwent saline SVG during general anesthesia just prior to their laparoscopy. RVS nodules were visualised as hypoechoic lesions of various shapes. The sonologist predicted whether or not a nodule was present in the retrocervical area or in the RVS. The thickness of the posterior vaginal wall ± RVS was then taken at three points in the mid-sagittal plane: at the posterior fornix (retrocervical area), at the middle third of the vagina (upper RVS) and just above the perineal body (lower RVS). The diagnosis of RVE was established using the gold standards of laparoscopy and histological confirmation. The RVS thickness was then compared between women with RVE and the absence of RVE. Results: Twenty-three women were enrolled in the study. Mean age was 38 years (33-44 years). A history of endometriosis was present in 72.7% (8/11). RVE was confirmed in 17.4% (4/23). Visualisation of a hypoechoic nodule at saline SVG demonstrated sensitivity and specificity of 75% and 95%, respectively. All rectovaginal nodules were located in the retrocervical region. Mean diameter (SD) of RVE nodules was 27.3 (± 9.4) mm. Mean thickness of vaginal wall ± RVS at the posterior fornix, at the middle third of the vagina and just above the perineal body was 5.1, 1.4 and 4.0 mm, respectively. These measurements were not significantly different in the presence of a rectovaginal nodule. Conclusions: Using saline SVG, we have established the mean RVS thickness in a small group of women with suspected RVE. Although the numbers are small, there was no correlation between RVS thickness and presence of RVE. The visualisation of hypoechoic lesions at saline SVG seems to be the best ultrasonographic predictor for RVE. SVG is a valuable pre-operative tool for the assessment of RVS and for the prediction of RVE, which allows for the mapping and planning of advanced endometriosis surgery.

Abstract
Endometriosis is a disease characterized by the presence of endometrial tissue outside of the uterine cavity. It is common in women of childbearing age, and is most frequently located in the pelvic cavity. Approximately 10% of endometriosis cases occur outside of the pelvic cavity in locations such as the intestines, genitourinary system, kidneys, lungs, and skin. However, there have been few reports of endometriosis in the stomach. Here, we report a rare case of endometriosis that presented as a subepithelial stomach tumor.

Abstract
Pelvic congestion syndrome (PCS) presents with a non-cyclic pelvic pain lasting more than six months in duration in premenopausal women. Pelvic ultrasonography or computed tomography is usually the first imaging modality used to evaluate patients with suspected PCS. PCS is confirmed by visible congestion of the pelvic veins on selective ovarian venography. To our knowledge, the role of endoscopic ultrasonography (EUS) has not been reported. EUS showed multiple dilated structures especially on left side around the uterus and ovaries, which are compatible with other radiological investigations of PCS Although PCS is not typical areas within the scope of practice of endosonographers, it is useful to be familiar with the findings. We report a case of PCS that was diagnosed with the aid of EUS.

Abstract
PURPOSE This study assessed the diagnostic accuracy of pelvic magnetic resonance (MR) imaging completed by MR colonography for the preoperative evaluation of deep pelvic endometriosis in patients undergoing laparoscopic surgery. MATERIALS AND METHODS A total of 143 patients (mean age 34.3 ± 5.1 years) with a clinical suspicion of deep pelvic endometriosis were assessed by pelvic MR and MR colonography. All patients underwent laparoscopic surgery 3-10 weeks after the MR examination. The presence, location, number and extent of endometriotic lesions were evaluated. Data obtained with MR were compared with surgical findings. MR sensitivity, specificity, positive (PPV) and negative (NPV) predictive values and diagnostic accuracy values were calculated for each site by considering the laparoscopic and histological findings as the reference standard. RESULTS Laparoscopy confirmed the presence of endometriosis in 119/143 patients (83%); in 76/119 (64%) deep pelvic endometriosis was diagnosed, whereas in the remaining 43/119 (36%), superficial peritoneal implants and endometriomas were found. In 32/119 (27%) patients, intestinal lesions were detected. MR had sensitivity, specificity, PPV, NPV and diagnostic accuracy values of 67-100%, 85-100%, 83-100%, 84-100% and 84-100%, respectively, in recognising lesions located in different pelvic sites. CONCLUSIONS MR imaging combined with colonography is a highly accurate tool for characterising deep endometriotic lesions in patients scheduled for laparoscopic surgery. In particular, MR colonography has very high accuracy in detecting colorectal involvement.

Abstract
The widespread use of endoscopic ultrasound has facilitated the evaluation of subepithelial and surrounding lesions of the gastrointestinal tract. Deep pelvic endometriosis, with or without infiltration of the intestinal wall, is a frequent disease that can be observed in women in their fertile age. Patients of this disease may present nonspecific signs and symptoms or be completely asymptomatic. Laparoscopic surgical resection of endometriotic lesions is the treatment of choice in symptomatic patients. An accurate preoperative evaluation is indispensable for therapeutic decisions mainly in the suspicion of intestinal wall and/or urinary tract infiltration, and also in cases where we need to establish histological diagnosis or to rule out malignant disease. Diagnostic tools, including transrectal ultrasound, magnetic resonance image, transvaginal ultrasound, barium enema, and colonoscopy, play significant roles in determining the presence, depth, histology, and other relevant data about the extension of the disease. Diagnostic algorithm depends on the clinical presentation, the expertise of the medical team, and the technology available at each institution. This article reviews and discusses relevant clinical points in endometriosis, including techniques and outcomes of the study of the disease through transrectal ultrasound and fine-needle aspiration.

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.

Abstract
AIM Endometriosis is defined by the presence of endometrial glands and stroma outside the uterus. The disease causes pelvic pain, dysmenorrhea, dyspareunia, dyschezia and urinary symptoms. The aim of this study was to assess the usefulness of endoscopic ultrasound (EUS) and elastosonography for detecting rectosigmoid endometriosis and to compare the findings, in selected and symptomatic patients, with surgical specimens in order to select the best surgical strategy. MATERIAL & METHODS Sixty-three consecutive patients (mean age 34.2; range 25-50 years) with diagnosis of endometriosis were referred for rectal endosonography to evaluate the rectal involvement. Patients complained of abdominal pain, rectal bleeding, constipation and dysmenorrhea. Sub-stenosis of the rectosigmoid lumen was found endoscopically in one patient (1.5%), bulging in 21 (33.3%), mucosal hyperemia or edema in one (1.5%), and no lesions in 39 patients (61.9%); no abdominal masses or obstruction were reported. Each woman completed a self-administered 100-point questionnaire to evaluate endometriosis-related pain (intensity of symptoms: 0 = absent, 100 = unbearable). After clinical imaging evaluation, 10 symptomatic patients (mean age 32.2; range 26-45 years) were evaluated for surgery. RESULTS EUS detected endometriotic lesions in all patients as a hypoechoic mass, poorly vascularized with irregular, undefined margins. In cases where the rectosigmoid wall was involved, there was invasion of the fourth layer. All patients who were operated had histologic findings of endometriotic lesions involving the rectal wall, as indicated by EUS. CONCLUSION EUS and elastosonography offers a non-invasive and sensitive technique to better define the endometriotic infiltration in the rectosigmoid wall.

Abstract
PURPOSE The anatomopathological significance of a positive double-contrast barium enema (DCBE) for suspicion of deep infiltrating endometriosis of the large bowel was studied. This is a retrospective study of a prospective database. METHODS A large-bowel resection was proposed for patients who were suspicious for large-bowel endometriosis and had a positive DCBE. In a series of 73 patients, 71 large-bowel resections were performed. Histology and immunohistochemistry with the monoclonal antibody CD-10 were performed on the resection specimen. Outcome measures were the length of the resected specimen, the largest diameter of the lesion, the positivity of the resection margins, and the degree of infiltration of the large bowel. We also compared the mean largest diameters of the lesions with the degree of infiltration of the large bowel. RESULTS Between December 1997 and October 2005, 80 patients were suspicious for large-bowel endometriosis: 73 (91%) had positive DCBEs, and 7 (9%) had negative DCBEs. Of the 73 with positive DCBEs, 4 (5%) refused digestive resection and 1 (1.4%) was excluded. Three patients underwent two large-bowel resections because of the presence of bifocal lesions (left and right colon). A total of 71 resections were performed. In case of positive DCBE, the perivisceral fat and the whole muscularis were infiltrated in 100% of cases. The infiltration reached the submucosa and the mucosa respectively in 82% and 18% of cases. A total of 9.9% of resection margins were positive at histology but only focally. The mean largest diameter of the lesions infiltrating the whole thickness of the large bowel was not statistically different from the mean largest diameter of more superficial lesions. CONCLUSIONS Findings of mass effect with indentations and ridging of the mucosa on DCBE in a setting suspicious for large-bowel endometriosis correspond well with pathologic findings of deep infiltration of the large-bowel wall. Clinicians dealing with deep infiltrating endometriosis should be aware of these findings, which could influence their choice of surgical treatment.

Abstract
BACKGROUND Transvaginal ultrasonography (TVUS) has important advantages compared with transrectal ultrasonography (TRUS): it is less invasive, is cost-effective, is a familiar and well-accepted approach, and anesthesia is not required. We compared the accuracy of TVUS and TRUS for diagnosing rectal wall involvement in patients presenting with histologically proved deeply infiltrating endometriosis (DIE). METHODS Prospective study of 134 patients with histologically proved DIE underwent preoperative investigations using both TVUS and TRUS. The radiologist (TVUS) and sonographer (TRUS) were unaware of the clinical findings but knew that DIE was suspected. RESULTS DIE was confirmed histologically for all the patients. A rectal wall involvement was histologically proved for 75 patients (56%). For the diagnosis of infiltration of the intestinal wall, TVUS and TRUS, respectively, had a sensitivity of 90.7% and 96.0%, a specificity of 96.5% and 100.0%, a positive predictive value of 97.1% and 100.0% and a negative predictive value of 88.9% and 95.2%. CONCLUSIONS TVUS and TRUS have similar degrees of accuracy for predicting intestinal involvement. TVUS must be the first-line imaging process to perform for patients presenting with clinically suspected DIE. The question for the coming years is to define if it is necessary for TRUS to be carried out systematically in cases of clinically suspected DIE.

Abstract
OBJECTIVES Indications of colorectal resection for endometriosis are controversial because of the risk of major complications. This study aims to evaluate the value of different diagnostic tests in decision-making, and to evaluate the surgical results and complications, as well as long-term functional results after surgery. PATIENTS AND METHODS In the set of a retrospective case series, 50 patients who have been admitted for a colorectal resection because of deep endometriosis were included. Most of them have had an MRI and an endorectal ultrasonography. Specific questionnaires have been proposed in order to evaluate symptoms, sexuality (BISF-W) and quality of life (EHP-30). RESULTS For the diagnosis of rectal involvement, the sensitivity of MRI and endorectal ultrasonography were 55 and 100%, respectively. Forty-one colorectal amputations and nine partial colorectal resections have been done by 24 laparotomies, two laparoscopies and 24 laparoconversions. Major complications included six (12.5%) digestive fistulas, three (6%) anastomotic strictures, one ureterovaginal fistula and one ureteral stricture. Risk factors associated with digestive fistulas were the association of a vaginal opening (p=0.002) and an additional ileocaecal resection (p=0.007). The mean follow-up period was of 42 months. A significant improvement of dysmenorrhea (p<10(-4)), dyschesia (p<10(-4)), chronic pelvic pain (p<10(-4)), and of some digestive symptoms such as catamenial epreintes (p=0.002) and catamenial diarrheas (p=0.006), was noted. We noted postoperative 14 dysurias, six constipations and 12 rectal polykynesias. Four patients have had deep recurrent lesions. Twenty patients had a desire of pregnancy after the operation, 17 pregnancies were obtained (eight spontaneous and nine by ART) giving birth to 14 living children. Sexuality evaluation was below normal range. The quality of life was improved for most of the items. The global satisfaction was good (91%). DISCUSSION AND CONCLUSION Colorectal resection for deep endometriosis improve significantly most of the pain symptoms, but the women should have detailed counselling about the risks of major complications and recurrence.

Abstract
Diagnostics and therapy of anorectal disorders are still questions of surgery. Exact knowledge of functional anatomy and precise clinical examination constitute the basis for the resulting therapeutic strategies. Three-dimensional endosonography and technical advances in flexible endoscopy using high-resolution chromoendoscopy and narrow-band imaging enable exact staging and diagnosis, even of malignancies in earliest stages. Furthermore new in-vivo staining methods combined with high-resolution imaging facilitate the discrimination of inflammatory and neoplastic lesions, which often lead to diagnostic difficulties in chronic inflammatory bowel disease. Developments in neurologic testing, including surface electromyography and sacral nerve stimulation, complement the diagnostic armamentarium.

Abstract
OBJECTIVE To describe a new surgical approach to rectovaginal endometriosis. Rectovaginal endometriosis can be infiltrative or superficial involving the bowel. Only infiltrative disease should be treated by intestinal resection. However, infiltration of endometriosis cannot be confirmed by preoperative imaging techniques. METHODS A total of 48 women with infiltrative rectovaginal endometriosis were included in this prospective study. Surgery was performed using a newly developed technique. All bowel resections were indicated according to operative findings and not on the basis of preoperative imaging technique results. RESULTS The decision for rectosigmoidal resection was based on the results of the intraoperative dissection of the rectovaginal septum. Histologically, infiltration of the ventral bowel wall was confirmed in all cases. CONCLUSION This new surgical technique for the treatment of rectovaginal endometriosis allows precise diagnosis and treatment with low morbidity. A resection of the mesorectum is not necessary because the endometriotic nodules are always located on the antimesenteric surface of the bowel.

Abstract
Gastrointestinal involvement of endometriosis has been found in 3%-37% of menstruating women and exclusive localization on the ileum is very rare (1%-7%). Endometriosis of the distal ileum is an infrequent cause of intestinal obstruction, ranging from 7% to 23% of all cases with intestinal involvement. We report a case in which endometrial infiltration of the small bowel caused acute obstruction requiring emergency surgery, in a woman whose symptoms were not related to menses. Histology of the resected specimen showed that endometriosis was mainly prevalent in the muscularis propria and submucosa and that the mucosa was not ulcerated but had inflammation and glandular alteration. Endometrial lymph node involvement, with a cystic glandular pattern was also detected.

Abstract
BACKGROUND The aim of this study was to determine whether adding water-contrast in the rectum during transvaginal ultrasonography (RWC-TVS) improves the diagnosis of rectal infiltration in women with rectovaginal endometriosis. METHODS This prospective study included 90 women, with suspect rectovaginal endometriosis, who underwent operative laparoscopy. TVS and RWC-TVS were independently performed by different investigators. RWC-TVS was performed by injecting saline solution into the rectal lumen under ultrasonographic control through a 6-mm catheter. Presence of rectovaginal nodules, presence and degree of rectal infiltration, and the largest diameter of the bowel nodules were evaluated. Ultrasonographic results were compared to surgical and histological findings. RESULTS Although RWC-TVS had higher accuracy than TVS in diagnosing rectovaginal endometriosis, the difference between the two techniques was not statistically significant. RWC-TVS was significantly more accurate than TVS in determining the presence of endometriotic infiltration reaching at least the muscular layer of the rectal wall. The sensitivity of RWC-TVS in identifying rectal lesions was 97%, the specificity 100%, the positive predictive value 100% and the negative predictive value 91.3%. RWC-TVS caused a higher intensity of pain than TVS. CONCLUSIONS RWC-TVS determines the presence of rectovaginal nodules infiltrating the rectal muscularis propria more accurately than TVS; RWC-TVS could be used when TVS cannot exclude the presence of rectal infiltration.

Abstract
OBJECTIVES To compare the accuracy of transvaginal sonography (TVS) and rectal endoscopic sonography (RES) for the diagnosis of deep infiltrating endometriosis (DIE), with respect to surgical and histological findings. METHODS This was a longitudinal study of 81 consecutive patients referred for surgical management of DIE, who underwent both TVS and RES preoperatively. The diagnostic criteria were identical for TVS and RES, and were based on visualization of hypoechoic areas in specific locations (uterosacral ligaments, vagina, rectovaginal septum and intestine). We calculated the sensitivity, specificity, predictive values and accuracy of TVS and RES for the diagnosis of DIE. RESULTS Endometriosis was confirmed histologically in 80/81 (98.7%) patients. Endometriomas and DIE were present in 43.2% and 97.5% of the women, respectively. For the diagnosis of DIE overall, TVS and RES, respectively, had a sensitivity of 87.3% and 74.7%, a positive predictive value of 98.6% and 98.3%, and an accuracy of 86.4% and 74%. For the diagnosis of uterosacral endometriosis, they had a sensitivity of 80.8% and 46.6%, a specificity of 75% and 50.0%, a positive predictive value of 96.7% and 89.5% and a negative predictive value of 30% and 9.3%. For the diagnosis of intestinal endometriosis, they had a sensitivity of 92.6% and 88.9%, a specificity of 100% and 92.6%, a positive predictive value of 100% and 96% and a negative predictive value of 87% and 80.6%. CONCLUSION TVS is apparently more accurate than is RES for predicting DIE in specific locations, and should thus be the first-line imaging technique in this setting.

Abstract
PURPOSE OF REVIEW Endometriosis is a frequent gynaecological disorder in young women. Colorectal endometriosis accounts for about 90% of all intestinal locations. The effectiveness of medical therapies is poor, and surgery, including colorectal resection, is therefore often required. Since the first description of laparoscopic colorectal resection by Redwine and Sharp, the feasibility of this approach has been confirmed by several teams but remains a matter of debate. RECENT FINDINGS A review of the literature showed that conversion to laparotomy was necessary in 7.8% of cases. Segmental colorectal resection appears to be the best option, owing to the risk of incomplete resection in the case of full-thickness disc or superficial-thickness excision. However, complications are more frequent with segmental resection than with other procedures, and include de-novo urinary disorders. Laparoscopic colorectal resection for endometriosis is associated with symptom relief and a significant improvement in quality of life. In addition, 44.6% of women wishing to conceive were able to do so. SUMMARY Laparoscopic colorectal resection for endometriosis appears to be an adequate alternative to laparotomy. Further studies are required to identify objective criteria with which to select women most likely to benefit from this surgery, which must be performed in special units.

Abstract
BACKGROUND The aim of this paper is to review the results of surgical excision of rectal endometriosis and review the published work on this challenging condition. METHODS All cases of endometriosis involving the rectum treated by a single colorectal surgeon were identified from a prospective database and the results reviewed. RESULTS Between 1995 and 2005, 213 rectal procedures were carried out on 203 patients together with an endogynaecologist. Eighteen cases involved dissection of endometriosis off the rectal wall, 58 involved full-thickness excision of the anterior rectal wall and 137 segmental excisions of the rectum were carried out. A loop ileostomy was required in 7 (5%) of the segmental resections. Seventy-five per cent of the cases were either laparoscopic or laparoscopically assisted. Infertility was significantly more common in the group requiring a segmental resection (P=0.026) and a history of rectal pain during defecation more common in patients having dissection of endometriosis off the rectal wall (P=0.031). There were no other significant differences between the different types of rectal surgery. The morbidity for all rectal procedures was 7% and there was one anastomotic leak in the segmental resection group. The actuarial rectal recurrence rate of endometriosis was 22.2% 95% confidence interval (CI) (2.5, 42.0) for dissection off the rectal wall and this was significantly different from the recurrence of 5.17% 95%CI (0.0, 10.9) for anterior rectal wall excision and 2.19% 95%CI (0.0, 4.6) for segmental rectal resection (P=0.007). The overall rectal recurrence for all cases was 4.69% 95%CI (1.8, 7.5). CONCLUSION Endometriosis of the rectum can be successfully treated with low morbidity and low recurrence rates by excising the disease as completely as possible using full-thickness excision of the anterior rectal wall or segmental resection of the rectum.

Abstract
BACKGROUND We compared the accuracy of magnetic resonance imaging (MRI) and rectal endoscopic sonography (RES) for the diagnosis of deep pelvic endometriosis (DPE), with respect to surgical and histological findings. METHODS Longitudinal study of 88 consecutive patients referred for surgical management of DPE, who underwent both MRI and RES pre operatively. The diagnostic criteria were identical for MRI and RES and were based on visualization of hypointense/hypoechoic areas in specific locations. DPE was diagnosed when at least one site was involved. We calculated the sensitivity, specificity, predictive values, accuracy and 95% confidence interval of MRI and RES for DPE. RESULTS DPE and endometriomas were present in 97.7 and 39.7% of women, respectively. The sensitivity, specificity and positive and negative predictive values of MRI and RES, respectively, were 84.8 and 45.6%, 88.8 and 40%, 98.5 and 87.8% and 40 and 8.5% for uterosacral endometriosis; 77.7 and 7.4%, 70% and 100, 85.3 and 100% and 89.7 and 70.9% for vaginal endometriosis and 88.3 and 90%, 92.8 and 89.3%, 96.4 and 94.7% and 78.8 and 80.6% for colorectal endometriosis. CONCLUSIONS MRI is more accurate than RES for the diagnosis of uterosacral and vaginal endometriosis, whereas the two methods are similarly accurate for colorectal endometriosis.

Abstract
Pelvic endometriosis primarily affects the ovaries, pelvic peritoneum, utero-sacral ligaments, Douglas pouch, vagina, rectum and bladder. Clinical assessment is difficult, and imaging proves necessary to determine location and extent of the disease. We review pelvic endometriosis with regards to imaging modalities: technical considerations, imaging patterns, diagnostic performance and respective place of ultrasound and MRI.

Abstract
PURPOSE OF REVIEW Endoscopic ultrasound has evolved as a useful technique for imaging and intervention in a variety of gastrointestinal and extraintestinal diseases including diseases of the colon and rectum. This paper will review recent developments in endoscopic ultrasound for colorectal diseases. RECENT FINDINGS Recent studies have shown significant clinical impact of endoscopic ultrasound in rectal cancer staging. Iliac lymph node evaluation by endoscopic ultrasound-guided fine needle aspiration may further expand the role of endoscopic ultrasound in rectal cancer. Three-dimensional endoscopic ultrasound may help decrease some of the errors of staging with two-dimensional endoscopic ultrasound and may further improve staging accuracy. Recent studies have confirmed continued problems with re-staging rectal cancer after chemoradiation. Endoscopic ultrasound-fine needle aspiration can be helpful in detecting local recurrence of rectal cancer and has been shown to be useful in evaluation of subepithelial masses of the colon and rectum and evaluation of rectosigmoid endometriosis. SUMMARY Endoscopic ultrasound continues to be useful for a variety of conditions of the colon and rectum with recent studies confirming its clinical impact as well as expanding its role into newer indications. Assessment for residual cancer after chemoradiation is still problematic and hopefully technological developments in ultrasound in the future may help in improving the accuracy of endoscopic ultrasound in this situation.

Abstract
Although several radiological techniques have been used for the diagnosis of bowel endometriosis, no gold standard is currently established. We used multislice computerized tomography (CT) combined with the distention of the colon by rectal enteroclysis (MSCTe) for the diagnosis of bowel endometriosis. Following bowel preparation, pharmacological hypotonicity, retrograde colonic distention by water enteroclysis, and intravenous injection of iodinated contrast medium, a single volumetric acquisition of the abdomen is performed. MSCTe findings suggestive of bowel endometriosis are the presence of solid nodules with positive enhancement, contiguous or penetrating the colonic wall. When endometriotic lesions are detected, the degree of infiltration of the intestinal wall can be estimated; however, the depth infiltrated by nodules reaching the submucosa may be underestimated. MSCTe is well tolerated by the patients. The strength of MSCT consists in the high spatial resolution; volumetric data acquired by using thin slices provide isotropic voxels and multiplanar reconstructions have a quality comparable with that of the original axial scans. The potential of MSCTe for the diagnosis of bowel endometriosis relies on the fact that the serosal, muscular, and mucosal layers of the bowel wall can be evaluated.

Abstract
This chapter summarizes the diagnostic performance (sensitivity, specificity, positive and negative likelihood ratios) of ultrasound, computer tomography, and magnetic resonance imaging in the diagnosis of various gynecological diseases and tumors. Positron emission tomography is not discussed. Imaging in infertility, in the diagnosis of Mullerian duct anomalies and in gynecological oncology (staging of gynecological cancers, diagnosis of recurrence of gynecological cancer, diagnosis of trophoblastic tumors) is not dealt with. Ultrasound is the first-line imaging method for discrimination between viable intrauterine pregnancy, miscarriage and tubal pregnancy in women with bleeding and/or pain in early pregnancy, for discrimination between benign and malignant adnexal masses and for making a specific diagnosis in adnexal tumors (e.g. dermoid cyst, endometrioma, hemorrhagic corpus luteum, etc.), for diagnosing intracavitary uterine pathology in women with bleeding problems, and for confirming or refuting pelvic pathology in women with pelvic pain. Magnetic resonance imaging can have a role as a secondary test in the diagnosis of adenomyosis, 'deep endometriosis' (e.g. endometriosis in the rectovaginal septum or in the uterosacral ligaments), and in the diagnosis of extremely rare types of ectopic pregnancy (e.g. in the spleen, liver or retroperitoneum).

Abstract
PURPOSE This study evaluated the validity of endorectal ultrasonography in predicting rectal infiltration in patients with deep pelvic endometriosis. METHODS Patients were recruited consecutively in the Department of Surgical Gynecology of Diaconesses Hospital from April 1996 to July 2003. Inclusion criteria were the suspicion of deep pelvic endometriosis on the basis of outpatient history and/or clinical symptoms with a mass palpable on bimanual examination that might infiltrate the rectal wall. There were no exclusion criteria. Endorectal ultrasonography was performed by the same investigator with a 7.5-MHz to 10-MHz rigid probe, producing a 360 degrees view of the rectal wall and adjacent areas. We used surgical and histopathologic findings as the "gold standard" to evaluate the validity of endorectal ultrasonography. RESULTS This study was based on 37 patients (mean age, 35.8 (range, 26-46) years) who underwent surgery. The time between endorectal ultrasonography and surgery ranged from 4 to 529 (mean, 88.7) days. Eight patients had endometriosis nodules penetrating the rectal wall. Endorectal ultrasonography showed sensitivity, specificity, a positive predictive value, and a negative predictive value of 87.5, 97, 87.5, and 97 percent, respectively, in the diagnosis of infiltration of the rectal wall by endometriosis. CONCLUSIONS Endorectal ultrasonography is a reliable technique for visualizing rectal infiltration in patients with deep pelvic endometriosis. It should be more widely used by gynecologists because knowing about rectal infiltration before surgery is fundamental to defining the best possible surgical approach.
