Abstract
INTRODUCTION AND HYPOTHESIS Endovaginal ultrasound has long been hypothesized to have a significant effect on locations of what it visualizes. However, little work has directly quantified its effect. This study aimed to quantify it. METHODS This cross-sectional study consisted of 20 healthy asymptomatic volunteers who underwent both endovaginal ultrasound and MRI. The urethra, vagina, rectum, pelvic floor, and pubic bone were segmented in both ultrasound and MRI using 3DSlicer. Then, using 3DSlicer's transform tool the volumes were rigidly aligned based on the posterior curvature of the pubic bone. The organs were then split into thirds along their long axis to compare their distal, middle, and proximal sections. Using Houdini, we compared the location of the centroid of each of the urethra, vagina, and rectum and the surface-to-surface difference of the urethra and rectum. The anterior curvature of the pelvic floor was also compared. Normality of all variables was assessed by Shapiro-Wilk test. RESULTS The largest amount of surface-to-surface distance was observed in the proximal region for the urethra and rectum. Across all three organs, the majority of the deviation was in the anterior direction for geometries obtained from ultrasound versus those from MRI. For each subject, the trace defining the midline of the levator plate was more anterior for ultrasound compared to MRI. CONCLUSIONS While it has often been assumed that placing a probe in the vagina probably distorts the anatomy, this study quantified the distortion and displacement of the pelvic viscera. This allows for better interpretation of clinical and research findings based on this modality.

Subramaniam N, Dietz HP. Is posterior compartment prolapse associated with anal incontinence? ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2023; 61:642-648. [PMID: 36565432 DOI: 10.1002/uog.26145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/04/2022] [Revised: 11/15/2022] [Accepted: 11/24/2022] [Indexed: 05/04/2023]
Abstract
OBJECTIVE It has been claimed that manifestations of posterior compartment prolapse, such as rectocele, enterocele and intussusception, are associated with anal incontinence (AI), but this has not been studied while controlling for anal sphincter trauma. We aimed to investigate this association in women with intact anal sphincter presenting with pelvic floor dysfunction. METHODS This retrospective study analyzed 1133 women with intact anal sphincter presenting to a tertiary urogynecological center for pelvic floor dysfunction between 2014 and 2016. All women underwent a standardized interview, including assessment of symptoms of AI, clinical examination and three-/four-dimensional transperineal ultrasound. Descent of the rectal ampulla, true rectocele, enterocele, intussusception and anal sphincter trauma were diagnosed offline. RESULTS Mean age was 54.1 (range, 17.6-89.7) years and mean body mass index was 29.4 (range, 14.7-67.8) kg/m2 . AI was reported by 149 (13%) patients, with a median St Mark's anal incontinence score of 12 (interquartile range, 1-23). Significant posterior compartment prolapse was seen in 693 (61%) women on clinical examination. Overall, 638 (56%) women had posterior compartment prolapse on imaging: 527 (47%) had a true rectocele, 89 (7.9%) had an enterocele and 26 (2.3%) had an intussusception. Women with ultrasound-diagnosed enterocele had a significantly higher rate of AI (23.6% vs 12.3%; odds ratio (OR), 2.21 (95% CI, 1.31-3.72); P = 0.002), but when adjusted for potential confounders, this association was no longer significant (OR, 1.56 (95% CI, 0.82-2.77); P = 0.134). CONCLUSION In women without anal sphincter trauma, posterior compartment prolapse, whether diagnosed clinically or by imaging, was not shown to be associated with AI. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Total pelvic floor ultrasound can reliably predict long-term treatment outcomes for patients with pelvic floor defaecatory dysfunction. Neurourol Urodyn 2023; 42:90-97. [PMID: 36153653 DOI: 10.1002/nau.25051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 07/30/2022] [Accepted: 09/05/2022] [Indexed: 01/03/2023]
Abstract
AIM Integrated total pelvic floor ultrasound (TPFUS) may provide an alternative to defaecation proctography (DP) in decision making and treatment planning for patients with pelvic floor defaecatory dysfunction (PFDD). This study evaluates the use of TPUS as a screening tool, and its likelihood to predict long-term treatment outcomes. METHODS Two blinded clinicians reviewed 100 women who had historically presented to a tertiary referral colorectal unit with PFDD from October 2014 to April 2015. The clinical history of the patients together with TPFUS or DP results were used to decide on main impression, treatment plan, likelihood of surgery and certainty of plan. These were compared to the actual treatment received six months later and again after a median follow-up of 68 months (range 48-84). RESULTS A total of 82 patients were treated with biofeedback only and 18 also underwent surgery. There were no complications in any of the patients who had surgery. When compared with the actual treatment received, 99 of the 100 of the TPFUS group would have been treated appropriately. The number of false positives for surgical treatment was lower with TPFUS compared to DP. Clinician confidence in the overall decision was significantly higher after review with DP. CONCLUSIONS TPFUS is a reliable assessment tool for PFDD. It can identify patients who can go straight to biofeedback and is just as good as DP at predicting likelihood of surgery. We might be able to rely on TPFUS more significantly in the future, even for surgical planning.

Abstract
BACKGROUND AND AIM Refractory bowel symptoms in quiescent inflammatory bowel disease (IBD) are common but evidence for effective management is limited. We aimed to determine whether behavioral treatment, including pelvic floor muscle training, decreases the severity of functional bowel symptoms in patients with quiescent IBD. Secondary aims were to evaluate the treatment effect on quality of life, psychological well-being and pelvic floor muscle function. METHODS This prospective study included IBD patients in remission with persistent symptoms of fecal incontinence or constipation who received up to six sessions of behavioral treatment at monthly intervals. The primary outcome was patient-rated symptom improvement on a 7-point Likert scale (1 = substantially worse, 7 = substantially better). Secondary outcomes included validated symptom scores, quality-of-life, psychological measures, and transperineal ultrasound assessment of pelvic floor muscle activity. RESULTS Thirty-four patients (median age 38 years; 24 females; 18 ulcerative colitis, 13 Crohn's disease, 3 ileo-anal pouch) were included. Twenty-one of the 29 (72%) patients who completed treatment, or 21 of all 34 (62%) patients, reported moderate or substantial improvement (patient rating of 6 or 7). Symptom scores (p < .001), IBD-specific quality of life (p = .008) and illness perception scores (p = .003) significantly improved. General quality of life, and anxiety and depression scores, did not change significantly. Transperineal ultrasound pelvic floor measures did not correlate with patient-rating of symptom improvement. CONCLUSION Significant symptomatic improvement occurred in a majority of patients with quiescent IBD. Behavioral treatment should be considered for patients with quiescent IBD and ongoing functional bowel symptoms of fecal incontinence, fecal urgency, or constipation.

Abstract
The aim of this study was to compare the data obtained by a pelvic organ prolapse quantification (POP-Q) examination with the translabial ultrasound (TLUS) quantification of prolapse, using a new method of angle measurement. We analyzed the TLUS and POP-Q exam findings of 452 patients with symptoms of POP. The POP-Q system was used for clinical staging. TLUS was performed both at rest, and during the Valsalva maneuver after proper preparation. A horizontal reference line was drawn through the inferior margin of the symphysis pubis and the levator plate connected to the rectal ampulla, and the difference was calculated between the rest and the Valsalva maneuver. The Spearman’s correlation coefficient of agreement between the TLUS and the clinical POP-Q staging was used for statistical analysis. There was a weak degree of correlation between the POP-Q findings for the Ap parameter and our new angle measurement (rho = 0.17, p < 0.001). Thus, POP staging in conjunction with TLUS with this new angle measurement shows better agreement for the diagnosis of POP than POP-Q staging alone.

Abstract
BACKGROUND Obstructed defaecation syndrome (ODS) is difficulty in evacuating stools, requiring straining efforts at defaecation, having the sensation of incomplete evacuation, or the need to manually assist defaecation. This is due to a physical blockage of the faecal stream during defaecation attempts, caused by rectocele, enterocele, intussusception, anismus or pelvic floor descent. Evacuation proctography (EP) is the most common imaging technique for diagnosis of posterior pelvic floor disorders. It has been regarded as the reference standard because of extensive experience, although it has been proven not to have perfect accuracy. Moreover, EP is invasive, embarrassing and uses ionising radiation. Alternative imaging techniques addressing these issues have been developed and assessed for their accuracy. Because of varying results, leading to a lack of consensus, a systematic review and meta-analysis of the literature are required. OBJECTIVES To determine the diagnostic test accuracy of EP, dynamic magnetic resonance imaging (MRI) and pelvic floor ultrasound for the detection of posterior pelvic floor disorders in women with ODS, using latent class analysis in the absence of a reference standard, and to assess whether MRI or ultrasound could replace EP. The secondary objective was to investigate differences in diagnostic test accuracy in relation to the use of rectal contrast, evacuation phase, patient position and cut-off values, which could influence test outcome. SEARCH METHODS We ran an electronic search on 18 December 2019 in the Cochrane Library, MEDLINE, Embase, SCI, CINAHL and CPCI. Reference list, Google scholar. We also searched WHO ICTRP and clinicaltrials.gov for eligible articles. Two review authors conducted title and abstract screening and full-text assessment, resolving disagreements with a third review author. SELECTION CRITERIA Diagnostic test accuracy and cohort studies were eligible for inclusion if they evaluated the test accuracy of EP, and MRI or pelvic floor ultrasound, or both, for the detection of posterior pelvic floor disorders in women with ODS. We excluded case-control studies. If studies partially met the inclusion criteria, we contacted the authors for additional information. DATA COLLECTION AND ANALYSIS Two review authors performed data extraction, including study characteristics, 'Risk-of-bias' assessment, sources of heterogeneity and test accuracy results. We excluded studies if test accuracy data could not be retrieved despite all efforts. We performed meta-analysis using Bayesian hierarchical latent class analysis. For the index test to qualify as a replacement test for EP, both sensitivity and specificity should be similar or higher than the historic reference standard (EP), and for a triage test either specificity or sensitivity should be similar or higher. We conducted heterogeneity analysis assessing the effect of different test conditions on test accuracy. We ran sensitivity analyses by excluding studies with high risk of bias, with concerns about applicability, or those published before 2010. We assessed the overall quality of evidence (QoE) according to GRADE. MAIN RESULTS Thirty-nine studies covering 2483 participants were included into the meta-analyses. We produced pooled estimates of sensitivity and specificity for all index tests for each target condition. Findings of the sensitivity analyses were consistent with the main analysis. Sensitivity of EP for diagnosis of rectocele was 98% (credible interval (CrI)94%-99%), enterocele 91%(CrI 83%-97%), intussusception 89%(CrI 79%-96%) and pelvic floor descent 98%(CrI 93%-100%); specificity for enterocele was 96%(CrI 93%-99%), intussusception 92%(CrI 86%-97%) and anismus 97%(CrI 94%-99%), all with high QoE. Moderate to low QoE showed a sensitivity for anismus of 80%(CrI 63%-94%), and specificity for rectocele of 78%(CrI 63%-90%) and pelvic floor descent 83%(CrI 59%-96%). Specificity of MRI for diagnosis of rectocele was 90% (CrI 79%-97%), enterocele 99% (CrI 96%-100%) and intussusception 97% (CrI 88%-100%), meeting the criteria for a triage test with high QoE. MRI did not meet the criteria to replace EP. Heterogeneity analysis showed that sensitivity of MRI performed with evacuation phase was higher than without for rectocele (94%, CrI 87%-98%) versus 65%, CrI 52% to 89%, and enterocele (87%, CrI 74%-95% versus 62%, CrI 51%-88%), and sensitivity of MRI without evacuation phase was significantly lower than EP. Specificity of transperineal ultrasound (TPUS) for diagnosis of rectocele was 89% (CrI 81%-96%), enterocele 98% (CrI 95%-100%) and intussusception 96% (CrI 91%-99%); sensitivity for anismus was 92% (CrI 72%-98%), meeting the criteria for a triage test with high QoE. TPUS did not meet the criteria to replace EP. Heterogeneity analysis showed that sensitivity of TPUS performed with rectal contrast was not significantly higher than without for rectocele(92%, CrI 69%-99% versus 81%, CrI 58%-95%), enterocele (90%, CrI 71%-99% versus 67%, CrI 51%-90%) and intussusception (90%, CrI 69%-98% versus 61%, CrI 51%-86%), and was lower than EP. Specificity of endovaginal ultrasound (EVUS) for diagnosis of rectocele was 76% (CrI 54%-93%), enterocele 97% (CrI 80%-99%) and intussusception 93% (CrI 72%-99%); sensitivity for anismus was 84% (CrI 59%-96%), meeting the criteria for a triage test with very low to moderate QoE. EVUS did not meet the criteria to replace EP. Specificity of dynamic anal endosonography (DAE) for diagnosis of rectocele was 88% (CrI 62%-99%), enterocele 97% (CrI 75%-100%) and intussusception 93% (CrI 65%-99%), meeting the criteria for a triage test with very low to moderate QoE. DAE did not meet the criteria to replace EP. Echodefaecography (EDF) had a sensitivity of 89% (CrI 65%-98%) and specificity of 92% (CrI 72%-99%) for intussusception, meeting the criteria to replace EP but with very low QoE. Specificity of EDF for diagnosis of rectocele was 89% (CrI 60%-99%) and for enterocele 97% (CrI 87%-100%); sensitivity for anismus was 87% (CrI 72%-96%), meeting the criteria for a triage test with low to very low QoE. AUTHORS' CONCLUSIONS In a population of women with symptoms of ODS, none of the imaging techniques met the criteria to replace EP. MRI and TPUS met the criteria of a triage test, as a positive test confirms diagnosis of rectocele, enterocele and intussusception, and a negative test rules out diagnosis of anismus. An evacuation phase increased sensitivity of MRI. Rectal contrast did not increase sensitivity of TPUS. QoE of EVUS, DAE and EDF was too low to draw conclusions. More well-designed studies are required to define their role in the diagnostic pathway of ODS.

Abstract
AIM To compare features on imaging (integrated total pelvic floor ultrasound (transperineal, transvaginal) and defaecation proctography) with bowel, bladder and vaginal symptoms in pelvic floor defaecatory dysfunction. METHOD A prospective observational case series of 216 symptomatic women who underwent symptom severity scoring (bowel, bladder and vaginal), integrated total pelvic floor ultrasound and defaecation proctography. Anatomical (rectocele, intussusception, enterocele, cystocele) and functional (co-ordination, evacuation) features were examined. RESULTS Irrespective of imaging modality, patients with a rectocele had higher International Consultation on Incontinence Modular Questionnaire - Vaginal Symptoms (ICIQ-VS) scores than patients without. On integrated total pelvic floor ultrasound, ICIQ-VS quality of life scores were higher in those with a rectocele. There was a higher International Consultation on Incontinence Modular Questionnaire - Bowel Symptoms (ICIQ-BS) bowel pattern score in those with a rectocele, and a lower ICIQ-BS bowel pattern and sexual impact score in those with intussusception. Poor co-ordination was associated with increased ICIQ-BS bowel control scores and obstructed defaecation symptom scores. On defaecation proctography, ICIQ-VS symptom scores were lower in patients with poor co-ordination. CONCLUSION Patients with a rectocele on either imaging modality may have qualitative vaginal symptoms on assessment. In patients with bowel symptoms but no vaginal symptoms, it is not possible to predict which anatomical abnormalities will be present on imaging.

Abstract
Rectal prolapse frequently occurs in conjunction with functional and anatomic abnormalities of the bowel and pelvic floor. Prolapse surgery should have as its goal not only to correct the prolapse, but also to improve function to the greatest extent possible. Careful history-taking and physical exam continue to be the surgeon's best tools to put rectal prolapse in its functional context. Physiologic testing augments this and informs surgical decision-making. Defecography can identify concomitant middle compartment prolapse and pelvic floor hernias, potentially targeting patients for urogynecologic consultation or combined repair. Other tests, including manometry, ultrasound, and electrophysiologic testing, may be of utility in select cases. Here, we provide an overview of available testing options and their individual utility in rectal prolapse.

Abstract
BACKGROUND Fecal incontinence is a disabling condition affecting up to 20% of women. OBJECTIVE We investigated fecal incontinence assessment in both inflammatory bowel disease and non-inflammatory bowel disease patients to propose a diagnostic approach for inflammatory bowel disease trials. METHODS We searched on Pubmed, Embase and Cochrane Library for all studies on adult inflammatory bowel disease and non-inflammatory bowel disease patients reporting data on fecal incontinence assessment from January 2009 to December 2019. RESULTS In total, 328 studies were included; 306 studies enrolled non-inflammatory bowel disease patients and 22 studies enrolled inflammatory bowel disease patients. In non-inflammatory bowel disease trials the most used tools were the Wexner score, fecal incontinence quality of life questionnaire, Vaizey score and fecal incontinence severity index (in 187, 91, 62 and 33 studies). Anal manometry was adopted in 41.2% and endoanal ultrasonography in 34.0% of the studies. In 142 studies (46.4%) fecal incontinence evaluation was performed with a single instrument, while in 64 (20.9%) and 100 (32.7%) studies two or more instruments were used. In inflammatory bowel disease studies the Wexner score, Vaizey score and inflammatory bowel disease quality of life questionnaire were the most commonly adopted tools (in five (22.7%), five (22.7%) and four (18.2%) studies). Anal manometry and endoanal ultrasonography were performed in 45.4% and 18.2% of the studies. CONCLUSION Based on prior validation and experience, we propose to use the Wexner score as the first step for fecal incontinence assessment in inflammatory bowel disease trials. Anal manometry and/or endoanal ultrasonography should be taken into account in the case of positive questionnaires.

Abstract
BACKGROUND Obstetric anal sphincter injuries (OASIS) are common and an important factor in the etiology of anal incontinence. The objective of this study was to evaluate, classify and compare the agreement of clinically diagnosed third-degree sphincter tears with 3D-transperineal ultrasound (3D-TPUS) realized within 3-7 days post-delivery. METHODS This is a retrospective observational study were 119 patients with third-degree obstetric anal sphincter tears were diagnosed and treated, 85 of those underwent a 3D-TPUS examination 3-7 days postpartum. We compared the proportion of third-degree perineal tears, classified with the clinical examination as grade 3a+b and grade 3c, with the 3D-TPUS. RESULTS In 16 patients with clinically diagnosed third-degree perineal tears grade a and b, the ultrasound examination confirmed the lesion of the external anal sphincter (EAS) muscle, but in nine patients (56% of the cases) we found a lesion of the internal anal sphincter (IAS) muscle, missed by clinical examination. In the remaining 69 patients with the third-degree perineal tears grade c, the ultrasound examination confirmed both lesions (EAS and IAS muscles) in 56 women, but in 13 patients (19% of the cases) defects of the IAS muscle could not be confirmed by the ultrasound. CONCLUSIONS There was moderate agreement regarding diagnosis of grade 3a+b and grade c perineal tears between ultrasound and clinical examination, so a combined use of clinical and ultrasound knowledge can improve the possibility to find a gold standard in the diagnosis of OASIS.

Abstract
PURPOSE The aim of this study was to determine the accuracy of 3-dimensional (3D) pelvic floor ultrasonography and compare it with defecography in assessment of posterior pelvic disorders. METHODS Eligible patients were consecutive women undergoing 3D pelvic floor ultrasonography at one hospital between August 2017 and February 2019. All 3D pelvic floor ultrasonography was performed by one examiner. A total of 167 patients with suspected posterior pelvic disorder was retrospectively enrolled in the study. The patients were divided into 3 groups according to the main symptoms. RESULTS There were 82 rectoceles on defecography (55 barium trapping) and 84 on 3D pelvic floor ultrasonography. Each modality identified 6 enteroceles. There were 43 patients with pelvic floor dyssynergia on defecography and 41 on ultrasonography. There were 84 patients with intussusception on defecography and 41 on 3D pelvic floor ultrasonography. Agreement of the 2 diagnostic tests was confirmed using Cohen's kappa value. Rectocele (kappa, 0.784) and enterocele (kappa, 0.654) both indicated good agreement between defecography and 3D pelvic floor ultrasonography. In addition, pelvic floor dyssynergia (kappa, 0.406) showed moderate agreement, while internal intussusception (kappa, 0.296) had fair agreement. CONCLUSION This study showed good agreement for detection of posterior pelvic disorders between defecography and 3D pelvic floor ultrasonography.

Abstract
Abstract
Background
Growing attention of pelvic floor disorders has led to development of new imaging techniques, with increasing importance of ultrasonography. The 3DUS technique is considered an accessible tool for imaging of the posterior pelvic compartment. The purpose of this study is to highlight the role of 3D ultrasound in evaluation of obstructed defecation in females and comparing the findings with defecography.
Results
Study included 30 females classified into two groups: (1) 20 patients (case group complaining of obstructed defecation); (2) ten females (control group-normal nulliparous females). All of them were subjected to defecography and 3D ultrasound during resting, squeezing, and straining. Detection rate of rectocele and intussusception with 3D ultrasound was lower than defecography. By US, significant statistical difference between patients and controls in all measurements of levator hiatus, IS, ES, and PRS thickness during straining (P value < 0.001). During straining, cut-off value of 20.75 cm2 for hiatal area gives sensitivity of 100% and specificity of 95% and using ARA, cut-off value of 105° gives sensitivity of 98% and specificity of 90% for differentiation between patients and controls.
Conclusion
Ultrasound can be considered a complementary test to defecography in investigation of patients with obstructed defecation. Ultrasound can diagnose levator muscle attenuation and avulsion, thickness of IS, ES, PRS, and distensibility of hiatal area.

Abstract
BACKGROUND Fecal incontinence (FI) and chronic constipation (CC) are disabling symptoms that cause a significant public health problem. The pathophysiology of combined constipation and FI is not fully understood. Our aim was to delineate the clinical, physiological and anatomical factors that may contribute to the association of FI and CC. METHODS A retrospective study was performed in a pelvic floor unit in a tertiary medical center. Consecutive female patients diagnosed with CC were included, and further divided into two groups according to the co-occurrence of FI. Demographic characteristics, anorectal physiology (obtained by manometry) and pelvic anatomical pathology (as assessed by dynamic pelvic ultrasound) were recorded and subsequently compared. RESULTS A total of 267 women were included in the study. Of those, 62 patients (23%) had an associated FI (CCFI). The CCFI group had higher body mass index (BMI) levels and a trend toward younger average age as compared to the group without FI (CCNFI). The number of vaginal and instrumental deliveries was similar in both groups. Anal resting and squeeze pressures were significantly lower in the CCFI group (64 ± 21 vs 48 ± 18, p = 0.004 and 141 ± 136.2 vs. 97.5 ± 38.6, p = 0.02, respectively). Rectal sensation abnormalities were common, but did not differ between both groups. Dyssynergic defecation and rectocele were more common in the CCNFI group (68% vs. 51%, p = 0.04 and 39% vs. 24%, p = 0/045, respectively. CONCLUSIONS Lower anal pressures and higher BMI were found among women with coexisting FI and CC. Pelvic floor anatomical and functional abnormalities are common in women diagnosed with CC and FI, but dyssynergia and diagnosis of significant rectocele, which cause obstructed defecation, were more common in the CCNFI group.

Abstract
AIM To assess the application value of dynamic magnetic resonance imaging (MRI) defecography in the diagnosis of outlet obstructive constipation (OCC).
METHODS Forty-eight patients with suspected OOC at Third Affiliated Hospital of Nanchang University from March 2016 to February 2018 were selected, and they underwent dynamic MRI defecography and X-ray defecography. The situations of dynamic MRI defecography and X-ray defecography were recorded. Using X-ray defecography as the standard, the specificity, sensitivity, negative predictive value, and positive predictive value of dynamic MRI defecography were calculated.
RESULTS There was no statistical difference in the diagnosis of intersigmoid hernia, puborectalis spasm, hernia, or internal hemorrhoid between dynamic MRI defecography and X-ray defecography (P > 0.05). The detection rates of dynamic MRI defecography in the diagnosis of rectocele, rectal mucosal prolapse, perinaeum descent, intrarectal invaginate, and sigmoid colon zigzagging were lower than those of X-ray defecography (P < 0.05). Dynamic MRI defecography could find lesions that cannot be displayed by X-ray defecography, including muscular rupture, uterine fibroid, cervical accepts cyst, sacral cyst, and mullerian duct cyst. Using X-ray defecography as the gold standard, the specificity and positive predictive value of dynamic MRI defecography in the diagnosis of rectal mucosal prolapse, rectocele, puborectalis spasm, intrarectal invaginate, intersigmoid hernia, hernia, sigmoid colon zigzagging, and perinaeum descent were all 100.00%; the sensitivity and positive predictive value for different diseases had a significant difference, the positive predictive value was generally higher, and the sensitivity was usually lower.
CONCLUSION MRI and X-ray defecography have their own advantages in the diagnosis of OOC. Dynamic MRI defecography can provide information on the pelvic organ and pelvic wall, pelvic floor function, and morphological structure, and it is a good supplement to X-ray defecography. Dynamic MRI defecography can provide guidance for overall evaluation and comprehensive diagnosis of OOC with pelvic multiple-organ lesions.

Does 4D transperineal ultrasound have additional value over 2D transperineal ultrasound for diagnosing posterior pelvic floor disorders in women with obstructed defecation syndrome? ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2018; 52:784-791. [PMID: 29882224 DOI: 10.1002/uog.19105] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/13/2017] [Revised: 04/26/2018] [Accepted: 05/13/2018] [Indexed: 06/08/2023]
Abstract
OBJECTIVE To establish the diagnostic test accuracy of two-dimensional (2D) and four-dimensional (4D) transperineal ultrasound (TPUS) for diagnosis of posterior pelvic floor disorders in women with obstructed defecation syndrome (ODS), in order to assess if 4D ultrasound imaging provides additional value. METHODS This was a prospective cohort study of 121 consecutive women with ODS. Symptoms of ODS and pelvic organ prolapse on clinical examination were assessed using validated methods. All women underwent both 2D- and 4D-TPUS. Imaging analysis was performed by two blinded observers. Posterior pelvic floor disorders were dichotomized into presence or absence, according to predefined cut-off values. In the absence of a reference standard, a composite reference standard was created from a combination of results of evacuation proctography, magnetic resonance imaging and endovaginal ultrasound. Primary outcome measures were diagnostic test characteristics of 2D- and 4D-TPUS for rectocele, enterocele, intussusception and anismus. Secondary outcome measures were interobserver agreement, agreement between the two imaging techniques, and association of severity of ODS symptoms and degree of posterior vaginal wall prolapse with conditions observed on imaging. RESULTS For diagnosis of all four posterior pelvic floor disorders, there was no difference in sensitivity or specificity between 2D- and 4D-TPUS (P = 0.131-1.000). Good agreement between 2D- and 4D-TPUS was found for diagnosis of rectocele (κ = 0.675) and moderate agreement for diagnoses of enterocele, intussusception and anismus (κ = 0.465-0.545). There was no difference in rectocele depth measurements between the techniques (19.9 mm for 2D vs 19.0 mm for 4D, P = 0.802). Interobserver agreement was comparable for both techniques, although 2D-TPUS had excellent interobserver agreement for diagnosis of enterocele and rectocele depth measurements, while this was only moderate and good, respectively, for 4D-TPUS. Diagnoses of rectocele and enterocele on both 2D- and 4D-TPUS were significantly associated with degree of posterior vaginal wall prolapse on clinical examination (odds ratio (OR) = 1.89-2.72). The conditions observed using either imaging technique were not associated with severity of ODS symptoms (OR = 0.82-1.13). CONCLUSIONS There is no evidence of superiority of 4D ultrasound acquisition to dynamic 2D ultrasound acquisition for the diagnosis of posterior pelvic floor disorders. 2D- and 4D-TPUS could be used interchangeably to screen women with symptoms of ODS.

Abstract
INTRODUCTION Our aim was to study any correlation between pelvic organ prolapse quantification (POP-Q) and ultrasound measurement of prolapse in women from a normal population and to identify the method with a stronger association with prolapse symptoms. METHODS A cross-sectional study of 590 parous women responding to the Pelvic Floor Distress Inventory was carried out. They were examined using POP-Q and transperineal ultrasound, and correlation was tested using Spearman's rank test. Numerical measurements and significant prolapse (POP-Q ≥ 2 in any compartment or bladder ≥10 mm, cervix ≥0 mm or rectal ampulla ≥15 mm below the symphysis on ultrasound) were compared in symptomatic and asymptomatic women (Mann-Whitney U and Chi-squared tests). RESULTS A total of 256 women had POP-Q ≥ 2 and 209 had significant prolapse on ultrasound. The correlation (rs) between POP-Q and ultrasound was 0.69 (anterior compartment), 0.53 (middle), and 0.39 (posterior), p < 0.01. Women with a "vaginal bulge" (n = 68) had greater descent on POP-Q and ultrasound in the anterior and middle compartments than asymptomatic women, p < 0.01. For women with a symptomatic bulge, the odds ratio was 3.8 (95% CI 2.2-6.7) for POP-Q ≥ grade 2 and 2.4 (95% CI 1.4-3.9) for prolapse on ultrasound. A sensation of heaviness (n = 90) and incomplete bladder emptying (n = 4) were more weakly associated with ultrasound (p = 0.03 and 0.04), and splinting (n = 137) was associated with POP-Q Bp, p = 0.02. CONCLUSION POP-Q and ultrasound measurement of prolapse had moderate to strong correlation in the anterior and middle compartments and weak correlation in the posterior compartment. Both methods were strongly associated with the symptom "vaginal bulge," but POP-Q had a stronger association than ultrasound.

Abstract
INTRODUCTION AND HYPOTHESIS Rectocele is common in parous women but also seen in nulliparae. This study was designed to investigate the association between vaginal parity and descent of the rectal ampulla/rectocele depth as determined by translabial ultrasound (TLUS). METHODS This retrospective observational study involved 1296 women seen in a urogynaecological centre. All had undergone an interview, clinical examination and 4D ultrasound (US) imaging supine and after voiding. Offline analysis of volume data was undertaken blinded against other data. Rectal ampulla position and rectocele depth were measured on Valsalva. A pocket depth of 10 mm was used as a cutoff to define rectocele on imaging. RESULTS Most women presented with prolapse (53%, n = 686); 810 (63%) complained of obstructed defecation (OD). Clinically, 53% (n = 690) had posterior-compartment prolapse with a mean Bp of -1 [standard deviation (SD)1.5; -3 to 9 cm]. Mean descent of the rectal ampulla was 10 mm below the symphysis (SD 15.8; -50 to 41). A rectocele on imaging was found in 48% (n = 618). On univariate analysis, OD symptoms were strongly associated with rectal descent, rectocele depth and rectocele on imaging (all P < 0.001). The prevalence of a rectocele seen on imaging increased with vaginal parity (P < 0.001). One-way analysis of variance (ANOVA) of vaginal parity against rectal descent and rectocele depth showed a dose-response relationship (both P < 0.001). CONCLUSIONS Vaginal parity was strongly associated with descent of the rectal ampulla and rectocele depth. This relationship approximated dose-response characteristics, with the greatest effect due to the first vaginal delivery.

Abstract
BACKGROUND Magnetic resonance defecography (MRD) allows for dynamic visualisation of the pelvic floor compartments when assessing for pelvic floor dysfunction. Additional benefits over traditional techniques are largely unknown. The aim of this study was to compare detection and miss rates of pelvic floor abnormalities with MRD versus clinical examination and traditional fluoroscopic techniques. METHODS A systematic review and meta-analysis was conducted in accordance with recommendations from the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. MEDLINE, Embase and the Cochrane Central Register of Controlled Trials were accessed. Studies were included if they reported detection rates of at least one outcome of interest with MRD versus EITHER clinical examination AND/OR fluoroscopic techniques within the same cohort of patients. RESULTS Twenty-eight studies were included: 14 studies compared clinical examination to MRD, and 16 compared fluoroscopic techniques to MRD. Detection and miss rates with MRD were not significantly different from clinical examination findings for any outcome except enterocele, where MRD had a higher detection rate (37.16% with MRD vs 25.08%; OR 2.23, 95% CI 1.21-4.11, p = 0.010) and lower miss rates (1.20 vs 37.35%; OR 0.05, 95% CI 0.01-0.20, p = 0.0001) compared to clinical examination. However, compared to fluoroscopy, MRD had a lower detection rate for rectoceles (61.84 vs 73.68%; OR 0.48 95% CI 0.30-0.76, p = 0.002) rectoanal intussusception (37.91 vs 57.14%; OR 0.32, 95% CI 0.16-0.66, p = 0.002) and perineal descent (52.29 vs 74.51%; OR 0.36, 95% CI 0.17-0.74, p = 0.006). Miss rates of MRD were also higher compared to fluoroscopy for rectoceles (15.96 vs 0%; OR 15.74, 95% CI 5.34-46.40, p < 0.00001), intussusception (36.11 vs 3.70%; OR 10.52, 95% CI 3.25-34.03, p = 0.0001) and perineal descent (32.11 vs 0.92%; OR 12.30, 95% CI 3.38-44.76, p = 0.0001). CONCLUSIONS MRD has a role in the assessment of pelvic floor dysfunction. However, clinicians need to be mindful of the risk of underdiagnosis and consider the use of additional imaging.

Abstract
OBJECTIVE To establish the diagnostic test accuracy of evacuation proctography, magnetic resonance imaging (MRI), transperineal ultrasonography, and endovaginal ultrasonography for detecting posterior pelvic floor disorders (rectocele, enterocele, intussusception, and anismus) in women with obstructed defecation syndrome and secondarily to identify the most patient-friendly imaging technique. METHODS In this prospective cohort study, 131 women with symptoms of obstructed defecation syndrome underwent evacuation proctogram, MRI, and transperineal and endovaginal ultrasonography. Images were analyzed by two blinded observers. In the absence of a reference standard, latent class analysis was used to assess diagnostic test accuracy of multiple tests with area under the curve (AUC) as the primary outcome measure. Secondary outcome measures were interobserver agreement calculated as Cohen's κ and patient acceptability using a visual analog scale. RESULTS No significant differences in diagnostic accuracy were found among the imaging techniques for all the target conditions. Estimates of diagnostic test accuracy were highest for rectocele using MRI (AUC 0.79) or transperineal ultrasonography (AUC 0.85), for enterocele using transperineal (AUC 0.73) or endovaginal ultrasonography (AUC 0.87), for intussusception using evacuation proctography (AUC 0.76) or endovaginal ultrasonography (AUC 0.77), and for anismus using endovaginal (AUC 0.95) or transperineal ultrasonography (AUC 0.78). Interobserver agreement for the diagnosis of rectocele (κ 0.53-0.72), enterocele (κ 0.54-0.94) and anismus (κ 0.43-0.81) was moderate to excellent, but poor to fair for intussusception (κ -0.03 to 0.37) with all techniques. Patient acceptability was better for transperineal and endovaginal ultrasonography as compared with MRI and evacuation proctography (P<.001). CONCLUSION Evacuation proctography, MRI, and transperineal and endovaginal ultrasonography were shown to have similar diagnostic test accuracy. Evacuation proctography is not the best available imaging technique. There is no one optimal test for the diagnosis of all posterior pelvic floor disorders. Because transperineal and endovaginal ultrasonography have good test accuracy and patient acceptability, we suggest these could be used for initial assessment of obstructed defecation syndrome.

ULTRASOUND IN OBSTETRICS & GYNECOLOGY : THE OFFICIAL JOURNAL OF THE INTERNATIONAL SOCIETY OF ULTRASOUND IN OBSTETRICS AND GYNECOLOGY 2017; 50:451-457. [PMID: 28000958 DOI: 10.1002/uog.17390] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/03/2016] [Revised: 12/02/2016] [Accepted: 12/13/2016] [Indexed: 06/06/2023]
Abstract
OBJECTIVE In recent years, a large number of studies have been published on the clinical relevance of pelvic floor three-dimensional (3D) transperineal ultrasound. Several studies compare sonography with other imaging modalities or clinical examination. The quality of reporting in these studies is not known. The objective of this systematic review was to determine the compliance of diagnostic accuracy studies investigating pelvic floor 3D ultrasound with the Standards for Reporting of Diagnostic Accuracy (STARD) guidelines. METHODS Published articles on pelvic floor 3D ultrasound were identified by a systematic literature search of MEDLINE, Web of Science and Scopus databases. Prospective and retrospective studies that compared pelvic floor 3D ultrasound with other clinical and imaging diagnostics were included in the analysis. STARD compliance was assessed and quantified by two independent investigators, using 22 of the original 25 STARD checklist items. Items with the qualifier 'if done' (Items 13, 23 and 24) were excluded because they were not applicable to all papers. Each item was scored as reported (score = 1) or not reported (score = 0). Observer variability, the total number of reported STARD items per article and summary scores for each item were calculated. The difference in total score between STARD-adopting and non-adopting journals was tested statistically, as was the effect of year of publication. RESULTS Forty studies published in 13 scientific journals were included in the analysis. Mean ± SD STARD checklist score of the included articles was 16.0 ± 2.5 out of a maximum of 22 points. The lowest scores (< 50%) were found for reporting of handling of indeterminate results or missing responses, adverse events and the time interval between tests. Interobserver agreement for rating the STARD items was excellent (intraclass correlation coefficient, 0.77). An independent t-test showed no significant mean difference ± SD in total STARD checklist score between STARD-adopting and non-adopting journals (16.4 ± 2.2 vs 15.9 ± 2.6, respectively). Mean ± SD STARD checklist score for articles published in 2003-2009 was lower, but not statistically different, compared with those published in 2010-2015 (15.2 ± 2.5 vs 16.6 ± 2.4, respectively). CONCLUSION The overall compliance with reporting guidelines of diagnostic accuracy studies on pelvic floor 3D transperineal ultrasound is relatively good compared with other fields of medicine. However, specific checklist items require more attention when reported. Copyright © 2016 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
INTRODUCTION AND HYPOTHESIS The objective was to evaluate the diagnostic potential of digital rectal examination in the identification of a true rectocele. METHODS This is a retrospective observational study utilising 187 archived data sets of women presenting with lower urinary tract symptoms and/or pelvic organ prolapse between August 2012 and November 2013. Evaluation included a standardised interview, ICS-POPQ, rectal examination and 4D translabial ultrasound. The main outcome measure was the diagnosis of rectocele by digital rectal palpation on Valsalva manoeuvre. This diagnosis correlated with the sonographic diagnosis of rectocele to determine agreement between digital examination and ultrasound findings. RESULTS Complete data sets were available for 180 participants. On imaging, the mean position of the rectal ampulla was 11.07 (-36.3 to 44.3) mm below the symphysis pubis; 42.8% (77) had a rectocele of a depth of ≥10 mm. On palpation, a rectocele was detected in 60 women (33%). Agreement between palpation and imaging was observed in 77%; the kappa was 0.52 (CI 0.39-0.65). On receiver operator characteristic analysis, the area under the curve was 0.854 for the relationship between rectocele pocket depth and the detection of rectocele on palpation. CONCLUSION Moderate agreement was found between digital rectal examination for rectocele and translabial ultrasound findings of a "true rectocele". Digital rectal examination may be used to identify these defects in clinical practice. Extending the clinical examination of prolapse to include rectal examination to palpate defects in the rectovaginal septum may reduce the need for defecatory proctograms for the assessment of obstructive defecation and may help triage patients in the management of posterior compartment prolapse.

Abstract
AIM Imaging for pelvic floor defaecatory dysfunction includes defaecation proctography. Integrated total pelvic floor ultrasound (transvaginal, transperineal, endoanal) may be an alternative. This study assesses ultrasound accuracy for the detection of rectocele, intussusception, enterocele and dyssynergy compared with defaecation proctography, and determines if ultrasound can predict symptoms and findings on proctography. Treatment is examined. METHOD Images of 323 women who underwent integrated total pelvic floor ultrasound and defaecation proctography between 2011 and 2014 were blindly reviewed. The size and grade of rectocele, enterocele, intussusception and dyssynergy were noted on both, using proctography as the gold standard. Barium trapping in a rectocele or a functionally significant enterocele was noted on proctography. Demographics and Obstructive Defaecation Symptom scores were collated. RESULTS The positive predictive value of ultrasound was 73% for rectocele, 79% for intussusception and 91% for enterocele. The negative predictive value for dyssynergy was 99%. Agreement was moderate for rectocele and intussusception, good for enterocele and fair for dyssynergy. The majority of rectoceles that required surgery (59/61) and caused barium trapping (85/89) were detected on ultrasound. A rectocele seen on both transvaginal and transperineal scanning was more likely to require surgery than if seen with only one mode (P = 0.0001). If there was intussusception on ultrasound the patient was more likely to have surgery (P = 0.03). An enterocele visualized on ultrasound was likely to be functionally significant on proctography (P = 0.02). There was, however, no association between findings on imaging and symptoms. CONCLUSION Integrated total pelvic floor ultrasound provides a useful screening tool for women with defaecatory dysfunction such that defaecatory imaging can avoided in some.

Abstract
Rectoanal intussusception is an invagination of the rectal wall into the lumen of the rectum. Patients may present with constipation, incomplete evacuation, incontinence, or may be asymptomatic. Defecography has been the gold standard for detection. Magnetic resonance imaging defecography and dynamic anal endosonography are alternatives to conventional defecography. However, both methods are not as sensitive as conventional defecography. Treatment options range from conservative/medical treatment such as biofeedback to surgical procedures such as Delorme, rectopexy, and stapled transanal rectal resection. Recent studies conducted after a trial of failed nonoperative management show adequate results with operations performed for rectal intussusception with or without rectocele if other causes of constipation are not present.

Ultrasound imaging in urogynecology - state of the art 2016. MENOPAUSE REVIEW 2016; 15:123-132.

Abstract
The role of ultrasound imaging in urogynecology is not clearly defined. Despite significant developments in visualization techniques and interpretation of images, pelvic ultrasound is still more a tool for research than for clinical practice. Structures of the lower genitourinary tract and pelvic floor can be visualized from different approaches: transperineal, introital, transvaginal, abdominal or endoanal. According to contemporary guidelines and recommendations, the role of ultrasound in urogynecology is limited to the measurement of post-void residue. However, in many instances, including planning and audit of surgical procedures, management of recurrences or complications, ultrasound may be proposed as the initial examination of choice. Ultrasound may be used for assessment of bladder neck mobility before anti-incontinence procedures. On rare occasions it is helpful in recognition of pathologies mimicking vaginal prolapse such as vaginal cyst, urethral diverticula or rectal intussusception. In patients subjected to suburethral slings, causes of surgery failure or postsurgical voiding dysfunctions can be revealed by imaging. Many reports link the location of a tape close to the bladder neck to unfavorable outcomes of sling surgery. Some postoperative complications, such as urinary retention, mesh malposition, hematoma, or urinary tract injury, can be diagnosed by ultrasound. On the other hand, the clinical value of some applications of ultrasound in urogynecology, for example measurement of the bladder wall thickness as a marker of detrusor overactivity, has not been proved.

Abstract
OBJECTIVE Defaecatory MRI allows multicompartmental assessment of defaecatory dysfunction but is often inaccessible. Integrated total pelvic floor ultrasound (transperineal, transvaginal, endoanal) may provide a cheap, portable alternative. The accuracy of total pelvic floor ultrasound for anatomical abnormalities when compared with defaecatory MRI was assessed. METHODS The dynamic images from 68 females who had undergone integrated total pelvic floor ultrasound and defaecatory MRI between 2009 and 2015 were blindly reviewed. The following were recorded: rectocoele, enterocoele, intussusception and cystocoele. RESULTS There were 26 rectocoeles on MRI (49 rectocoeles on ultrasound), 24 rectocoeles with intussusception on MRI (19 rectocoeles on ultrasound), 23 enterocoeles on MRI (24 enterocoeles on ultrasound) and 49 cystocoeles on MRI (35 cystocoeles on ultrasound). Sensitivity and specificity of total pelvic floor ultrasound were 81% and 33% for rectocoele, 60% and 91% for intussusception, 65% and 80% for enterocoele and 65% and 84% for cystocoele when compared with defaecatory MRI. This gave a negative-predictive value and positive-predictive value of 74% and 43% for rectocoele, 80% and 79% for intussusception, 82% and 63% for enterocoele and 48% and 91% for cystocoele. CONCLUSION Integrated total pelvic floor ultrasound may serve as a screening tool for pelvic floor defaecatory dysfunction; when normal, defaecatory MRI can be avoided, as rectocoele, intussusception and enterocoele are unlikely to be present. Advances in knowledge: This is the first study to compare integrated total pelvic floor ultrasound with defaecatory MRI. The results support the use of integrated total pelvic floor ultrasound as a screening tool for defaecatory dysfunction.
