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
AIM To assess the role of three-dimensional endoanal ultrasound (3D-EAUS) for morphological assessment of the anal sphincter of female patients with chronic proctalgia (CP).
METHODS In this unmatched case control study, 30 consecutive female patients with CP and 25 normal women (control group) were enrolled. 3D-EAUS was performed in all subjects. Thickness and length of internal anal sphincter (IAS), thickness of puborectalis muscle (PR), length of the external anal sphincter (EAS) plus PR, and puborectalis angle were measured and compared between the two groups.
RESULTS Patients with CP had significantly shorter IAS length and greater PR thickness, as compared to those in normal individuals (26.28 ± 3.59 mm vs 28.87 ± 4.84 mm, P < 0.05 and 9.67 ± 1.57 mm vs 8.85 ± 0.97 mm, P < 0.05, respectively). No significant between-group differences were observed with respect to IAS thickness and the EAS plus PR length (P > 0.05). Puborectalis angle in the CP group was significantly decreased, both in resting (88.23° ± 1.81° vs 89.94° ± 2.07° in control group, P < 0.05) and straining (88.47° ± 3.32° vs 90.72° ± 1.87° in control group, P < 0.05) phases, which suggest the presence of paradoxical contraction of PR in patients with CP. In the CP group, no significant difference in puborectalis angle was observed between the resting and straining phases (88.23° ± 1.81° vs 88.47° ± 3.32° respectively, P > 0.05).
CONCLUSION The association of greater PR thickness and paradoxical contraction of PR with CP suggest their potential value as markers of CP.

Abstract
BACKGROUND Defecography is an established method of evaluating dynamic anorectal dysfunction, but conventional defecography does not allow for visualization of anatomic structures. OBJECTIVE The purpose of this study was to describe the use of dynamic 3-dimensional endovaginal ultrasonography for evaluating perineal descent in comparison with echodefecography (3-dimensional anorectal ultrasonography) and to study the relationship between perineal descent and symptoms and anatomic/functional abnormalities of the pelvic floor. DESIGN This was a prospective study. SETTING The study was conducted at a large university tertiary care hospital. PATIENTS Consecutive female patients were eligible if they had pelvic floor dysfunction, obstructed defecation symptoms, and a score >6 on the Cleveland Clinic Florida Constipation Scale. INTERVENTIONS Each patient underwent both echodefecography and dynamic 3-dimensional endovaginal ultrasonography to evaluate posterior pelvic floor dysfunction. MAIN OUTCOME MEASURES Normal perineal descent was defined on echodefecography as puborectalis muscle displacement ≤2.5 cm; excessive perineal descent was defined as displacement >2.5 cm. RESULTS Of 61 women, 29 (48%) had normal perineal descent; 32 (52%) had excessive perineal descent. Endovaginal ultrasonography identified 27 of the 29 patients in the normal group as having anorectal junction displacement ≤1 cm (mean = 0.6 cm; range, 0.1-1.0 cm) and a mean anorectal junction position of 0.6 cm (range, 0-2.3 cm) above the symphysis pubis during the Valsalva maneuver and correctly identified 30 of the 32 patients in the excessive perineal descent group. The κ statistic showed almost perfect agreement (κ = 0.86) between the 2 methods for categorization into the normal and excessive perineal descent groups. Perineal descent was not related to fecal or urinary incontinence or anatomic and functional factors (sphincter defects, pubovisceral muscle defects, levator hiatus area, grade II or III rectocele, intussusception, or anismus). LIMITATIONS The study did not include a control group without symptoms. CONCLUSIONS Three-dimensional endovaginal ultrasonography is a reliable technique for assessment of perineal descent. Using this technique, excessive perineal descent can be defined as displacement of the anorectal junction >1 cm and/or its position below the symphysis pubis on Valsalva maneuver.

Abstract
Rectocele is one of the common manifestations of outlet obstructive constipation. There are several imaging methods for evaluating rectocele including conventional defecography, dynamic nuclear magnetic resonance imaging (MRI) defecography and pelvic floor ultrasonography. These diagnostic techniques can identify the degree of rectocele and provide evidence for treatment. Defecography is still considered the gold standard for evaluating rectocele and guiding the operation, but it exposes patients to radiation. MRI defecography has the advantages of multi-dimensional imaging, excellent soft-tissue contrast and no radiation, and has broad prospects in the future, but it is expensive nowadays and has an unphysiological defecation way. Pelvic floor ultrasonography, especially endoanal and transperineal techniques, is able to identify all dysfunctions of the posterior pelvic floor compartment without radiation, but needs further studies.

Abstract
BACKGROUND New ultrasound techniques may complement current diagnostic tools, and combined techniques may help to overcome the limitations of individual techniques for the diagnosis of anorectal dysfunction. A high degree of agreement has been demonstrated between echodefecography (dynamic 3-dimensional anorectal ultrasonography) and conventional defecography. OBJECTIVE Our aim was to evaluate the ability of a combined approach consisting of dynamic 3-dimensional transvaginal and transrectal ultrasonography by using a 3-dimensional biplane endoprobe to assess posterior pelvic floor dysfunctions related to obstructed defecation syndrome in comparison with echodefecography. DESIGN AND SETTING This was a prospective, observational cohort study conducted at a tertiary-care hospital. PATIENTS Consecutive female patients with symptoms of obstructed defecation were eligible. INTERVENTION Each patient underwent assessment of posterior pelvic floor dysfunctions with a combination of dynamic 3-dimensional transvaginal and transrectal ultrasonography by using a biplane transducer and with echodefecography. MAIN OUTCOME MEASURES Kappa (κ) was calculated as an index of agreement between the techniques. Diagnostic accuracy (sensitivity, specificity, and positive and negative predictive values) of the combined technique in detection of posterior dysfunctions was assessed with echodefecography as the standard for comparison. RESULTS A total of 33 women were evaluated. Substantial agreement was observed regarding normal relaxation and anismus. In detecting the absence or presence of rectocele, the 2 methods agreed in all cases. Near-perfect agreement was found for rectocele grade I, grade II, and grade III. Perfect agreement was found for entero/sigmoidocele, with near-perfect agreement for rectal intussusception. Using echodefecography as the standard for comparison, we found high diagnostic accuracy of transvaginal and transrectal ultrasonography in the detection of posterior dysfunctions. LIMITATIONS This combined technique should be compared with other dynamic techniques and validated with conventional defecography. CONCLUSIONS Dynamic 3-dimensional transvaginal and transrectal ultrasonography is a simple and fast ultrasound technique that shows strong agreement with echodefecography and may be used as an alternative method to assess patients with obstructed defecation syndrome.

Abstract
Constipation caused by female pelvic floor dysfunction (FPFD) is closely related to pathological changes in the front, middle and back basins. Constipation caused by pathological changes in the back basin manifests itself as rectocele, internal rectal intussusception, enterocele, descending perineum, and pelvic floor dyssynergia. Constipation due to the pathological changes in the front and middle basins not only manifests the above symptoms but also exhibits the symptoms of uterine and bladder prolapse. Pelvic floor ultrasound allows observing pathological changes in the front, middle and back basins in patients with constipation caused by FPFD, analyzing the changes in structure and function of static and dynamic pelvic floors, and making a more systematic assessment of female pelvic floor lesions, which is conducive to guiding constipation treatment. Therefore, pelvic floor ultrasound has great value in constipation caused by FPFD. In this paper, we review the diagnostic value of pelvic floor ultrasound in constipation due to female pelvic floor dysfunction.

Abstract
AIM The purpose of the study was to describe a novel three-dimensional dynamic anorectal ultrasonography technique (dynamic 3-DAUS) for assessment of perineal descent (PD) and establishment of normal range values, comparing it with defaecography. Secondarily, the study compares the ability of the two techniques to identify various pelvic floor dysfunctions. METHOD A prospective study was undertaken in 29 women (mean age 43 years) with obstructed defecation disorder. All patients underwent defaecography and dynamic 3-DAUS and the results were compared. Lee kappa coefficients (K) were used. RESULTS On defaecography, PD > 3 cm was detected in 12 patients. On dynamic 3-DAUS, 10 of these patients had PD > 2.5 cm. Seventeen had normal PD on defaecography and PD ≤ 2.5 cm on dynamic 3-DAUS (K 0.85). Normal relaxation was observed in 10 patients and anismus in 14 with both techniques (K 0.65). Both techniques identified five patients without rectocele, two with grade I rectocele (K 0.89 and 1.00, respectively) and 10 with grade II and nine with grade III (K 0.72 and 0.77, respectively). Rectal intussusception was identified in six patients on defaecography. These were confirmed on dynamic 3-DAUS in addition to the identification of another seven cases indicating moderate agreement (K 0.46). Enterocele/sigmoidocele grade III was identified in one patient with both techniques, indicating substantial agreement (K 0.65). CONCLUSION Dynamic 3-DAUS was shown to be a reliable technique for the assessment of PD and pelvic floor dysfunctions, identifying all disorders and confirming findings from defaecography.

Abstract
CONTEXT The correlation between vaginal delivery, age and pelvic floor dysfunctions involving obstructed defecation is still a matter of controversy. OBJECTIVES To determine the influence of age, mode of delivery and parity on the prevalence of posterior pelvic floor dysfunctions in women with obstructed defecation syndrome. METHODS Four hundred sixty-nine females with obstructed defecation syndrome were retrospectively evaluated using dynamic 3D ultrasonography to quantify posterior pelvic floor dysfunctions (rectocele grade II or III, rectal intussusception, paradoxical contraction/non-relaxation of the puborectalis and entero/ sigmoidocele grade III). In addition, sphincter damage was evaluated. Patients were grouped according to age (≤50y x >50y) and stratified by mode of delivery and parity: group I (≤50y): 218 patients, 75 nulliparous, 64 vaginal delivery and 79 only cesarean section and group II (>50y): 251 patients, 60 nulliparous, 148 vaginal delivery and 43 only caesarean section. Additionally, patients were stratified by number of vaginal deliveries: 0 - nulliparous (n = 135), 1 - vaginal (n = 46), >1 - vaginal (n = 166). RESULTS Rectocele grade II or III, intussusception, rectocele + intussusception and sphincter damage were more prevalent in Group II (P = 0.0432; P = 0.0028; P = 0.0178; P = 0.0001). The stratified groups (nulliparous, vaginal delivery and cesarean) did not differ significantly with regard to rectocele, intussusception or anismus in each age group. Entero/sigmoidocele was more prevalent in the vaginal group <50y and in the nulliparous and vaginal groups >50y. No correlation was found between rectocele and the number of vaginal deliveries. CONCLUSION Higher age (>50 years) was shown to influence the prevalence of significant rectocele, intussusception and sphincter damage in women. However, delivery mode and parity were not correlated with the prevalence of rectocele, intussusception and anismus in women with obstructed defecation.

Abstract
BACKGROUND Pelvic floor disorders are frequent, especially in women. Surgeons need more information on the accuracy of available diagnostic techniques to make therapeutic decisions. OBJECTIVE This study aimed to compare the accuracy of dynamic anorectal endosonography and dynamic MRI defecography with conventional defecography as the criterion standard in the diagnosis of pelvic floor disorders. DESIGN We used a prospective crossover design in which patients underwent each procedure in random order within the same month. SETTING Investigations were conducted at a regional referral center in Marseille, France. PATIENTS Women with dyschezia who were undergoing diagnostic evaluation were eligible. INTERVENTION Dynamic anorectal endosonography, dynamic MRI, and conventional defecography were performed in all patients by 3 blinded operators. MAIN OUTCOME MEASURE The accuracy of dynamic anorectal endosonography and dynamic MRI in the diagnosis of pelvic floor disorders was assessed by calculating sensitivity, specificity, positive and negative predictive values, correlation coefficients, concordance rates, and the Cohen κ statistic, with conventional defecography used as the criterion standard. RESULTS The study comprised 56 women with a mean age of 50.7 (SD, 12.5) years. No significant differences were observed between dynamic anorectal endosonography and dynamic MRI in the number of patients with rectocele (P = .49), perineal descent (P = .11 when dynamic anorectal endosonography measured descent of the puborectalis muscle; P = .27 for bladder descent), or enterocele (P = .78); no differences were found between these techniques in sensitivity, specificity, or positive and negative predictive values. Diagnostic concordance with conventional defecography as the standard did not differ significantly between dynamic MRI and dynamic anorectal endosonography: Concordance rates for dynamic anorectal endosonography were 75% for rectocele, 64% for perineal descent, and 91% for enterocele (no rectal intussusception was found with dynamic anorectal endosonography); concordance rates for dynamic MRI were 82% for rectocele, 57% for perineal descent, 93% for enterocele, and 55% for rectal intussusception. Significantly more internal anal sphincter defects were found with dynamic anorectal endosonography than with dynamic MRI defecography: 21 patients (37.5%) vs 12 patients (21.4%); P = .02. Patient tolerance was significantly better for dynamic anorectal endosonography than for dynamic MRI (P = .002) or conventional defecography (P = .005). Most patients said they would choose dynamic anorectal endosonography (72.1%) rather than dynamic MRI (25.6%) or conventional defecography (2.3%) if follow-up were necessary (P < .001). CONCLUSION Dynamic anorectal endosonography and dynamic MRI defecography show equivalent diagnostic performance in assessing pelvic floor disorders. However, because of its better tolerance and availability, dynamic anorectal endosonography may be preferable as the initial imaging procedure after clinical examination in the evaluation of pelvic floor disorders.

ARQUIVOS DE GASTROENTEROLOGIA 2011; 47:368-72. [PMID: 21225147 DOI: 10.1590/s0004-28032010000400009] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2010] [Accepted: 05/12/2010] [Indexed: 01/18/2023]
Abstract
CONTEXT Anismus is a prevalent functional cause of outlet delay. It is characterized by symptoms of obstructed defecation associated with paradoxical contraction of the pelvic floor muscles. OBJECTIVE To evaluate the ability of two dimensional anal ultrasonography to identify anismus patients with paradoxical contraction or normal relaxation, comparing findings with manometric measurements. METHODS Forty-nine women presenting with outlet delay and a mean validated Wexner constipation score of 13.5 were included in a prospective study. Following screening with anal manometry, the patients were assigned to one of two groups: G-I -with normal relaxation and G-II -patients with anismus. Dynamic anorectal ultrasonography was used to quantifier the movement of the puborectalis muscle and to measure changes in the angle between two converging lines drawn from the 3 o'clock and the 9 o'clock positions of the endoprobe circumference to the internal border of the puborectalis muscle. The angle decreases during straining in patients with normal relaxation, but increases in patients with anismus. The agreement between the two techniques was verified with the Kappa index. RESULTS In manometry, during straining the anal canal pressure decreased by 41.3% in G-I and increased by 168.6% in G-II, indicating a diagnosis of anismus for the second group. In US, during straining, the angle produced by the movement of the puborectalis muscle decreased from 63 ± 1.31 to 58 ± 1.509 degrees (P = 0.0135) in 23 of the 30 patients in G-I, indicating normal relaxation, and increased from 66 ± 0.972 to 72 ± 0.897 degrees (P = 0.0001) in 16 of the 19 patients in G-II, indicating anismus. The index of agreement between manometry and two dimensional anal ultrasonography was moderate: 77% (23/30) for G-I and 84% (16/19) for G-II. CONCLUSION Two-dimensional dynamic anal ultrasonography showed similar results previously suggested by anal manometry at identifying patients with normal relaxation or paradoxical contraction.

Abstract
BACKGROUND Defecography is the gold standard for assessing functional anorectal disorders but is limited by the need for a specific radiologic environment, exposure of patients to radiation, and inability to show all anatomic structures involved in defecation. Echodefecography is a 3-dimensional dynamic ultrasound technique developed to overcome these limitations. OBJECTIVE This study was designed to validate the effectiveness of echodefecography compared with defecography in the assessment of anorectal dysfunctions related to obstructed defecation. DESIGN Multicenter, prospective observational study. PATIENTS Women with symptoms of obstructed defecation. SETTING Six centers for colorectal surgery (3 in Brazil, 1 in Texas, 1 in Florida, and 1 in Venezuela). INTERVENTIONS Defecography was performed after inserting 150 mL of barium paste in the rectum. Echodefecography was performed with a 2050 endoprobe through 3 automatic scans. MAIN OUTCOME MEASURES The κ statistic was used to assess agreement between echodefecography and defecography in the evaluation of rectocele, intussusception, anismus, and grade III enterocele. RESULTS Eighty-six women were evaluated: median Wexner constipation score, 13.4 (range, 6-23); median age, 53.4 (range, 26-77) years. Rectocele was identified with substantial agreement between the 2 methods (defecography, 80 patients; echodefecography, 76 patients; κ = 0.61; 95% CI = 0.48-0.73). The 2 techniques demonstrated identical findings in 6 patients without rectocele, and in 9 patients with grade I, 29 with grade II, and 19 patients with grade III rectoceles. Defecography identified rectal intussusception in 42 patients, with echodefecography identifying 37 of these cases, plus 4 additional cases, yielding substantial agreement (κ = 0.79; 95% CI = 0.57-1.0). Intussusception was associated with rectocele in 28 patients for both methods (κ = 0.62; 95% CI = 0.41-0.83). There was substantial agreement for anismus (κ = 0.61; 95% CI = 0.40-0.81) and for rectocele combined with anismus (κ = 0.61; 95% CI = 0.40-0.82). Agreement for grade III enterocele was classified as almost perfect (κ = 0.87; 95% CI = 0.66-1.0). LIMITATIONS Echodefecography had limited use in identification of grade I and II enteroceles because of the type of probe used. CONCLUSIONS Echodefecography may be used to assess patients with obstructed defecation, as it is able to detect the same anorectal dysfunctions found by defecography. It is minimally invasive and well tolerated, avoids exposure to radiation, and clearly demonstrates all the anatomic structures involved in defecation.

Abstract
Abnormal motor patterns are implicated in many motility disorders. However, for many regions of the gut, our knowledge of normal and abnormal motility behaviors and mechanisms remains incomplete. There have been many recent advances in the development of techniques to increase our knowledge of gastrointestinal motility, some readily available while others remain confined to research centers. This review highlights a range of these recent developments and examines their potential to help diagnose and guide treatment for motility disorders.

Abstract
OBJECTIVE The aim of this prospective study was to test two-dimensional dynamic anorectal ultrasonography (2D-DAUS) in the assessment of anismus and compare it with echodefecography (ECD). METHOD Fifty consecutive female patients with outlet delay were submitted to 2D and 3D-DAUS, measuring the relaxing or contracting puborectalis muscle angle during straining. The patients were assigned to one of two groups based on ECD findings. Group I consisted of 29 patients without anismus and group II included 21 patients diagnosed with anismus. Subsequently 2D-DAUS images were checked for anismus and compared with ECD findings. RESULTS Upon straining, the angle produced by the movement of the puborectalis muscle decreased in 26 out of the 29 (89.6%) patients of group I and increased 19 out of the 21 (90.4%) patients of group II. The mean angle during straining differed significantly between group I and group II. The index of agreement between the two scanning modes was 89.6% (26/29) for group I (Kappa: 0.796; CI: 95%; range: 0.51-1.0) and 90.4% (19/21) for group II (Kappa: 0.796; CI: 95%; range: 0.51-1.0). CONCLUSION Two-dimensional dynamic anal ultrasonography can be used as an alternative method to assess patients with anismus, although the 3-D modality is more precise to evaluate the PR angle as the sphincters integrity as the whole muscle length is clearly visualized.

Abstract
PURPOSE This study aims to show pelvic floor dysfunctions in women with obstructed defecation syndrome (ODS), comparing nulliparous to those with vaginal delivery or cesarean section using the echodefecography (ECD). MATERIALS AND METHODS Three hundred seventy female patients with ODS were reviewed retrospectively and were divided in Group I-105 nulliparous, Group II-165 had at least one vaginal delivery, and Group III-comprised of 100 patients delivered only by cesarean section. All patients had been submitted to ECD to identify pelvic floor dysfunctions. RESULTS No statistical significance was found between the groups with regard to anorectocele grade. Intussusception was identified in 40% from G I, 55.0% from G II, and 30.0% from G III, with statistical significance between Groups I and II. Intussusception was associated with significant anorectocele in 24.8%, 36.3%, and 18% patients from G I, II, and III, respectively. Anismus was identified in 39.0% from G I, 28.5% from G II, and 60% from G III, with statistical significance between Groups I and III. Anismus was associated with significant anorectocele in 22.8%, 15.7%, and 24% patients from G I, II, and III, respectively. Sigmoidocele/enterocele was identified in 7.6% from G I, 10.9% G II, and was associated with significant rectocele in 3.8% and 7.3% patients from G I and II, respectively. CONCLUSION The distribution of pelvic floor dysfunctions showed no specific pattern across the groups, suggesting the absence of a correlation between these dysfunctions and vaginal delivery.

Abstract
Chronic constipation is a widespread problem which affects approximately 63 million people in North America alone. Although the majority of patients respond to changes in dietary fiber and water intake, as well as the judicious use of laxatives, a small portion will not and as a result, will be evaluated by gastroenterologists and colorectal surgeons. These patients most frequently have slow transit constipation, pelvic floor dysfunction, or some combination of the two. The physiologic evaluation of these patients comprises colonic transit studies, anorectal manometry, cinedefecography, electromyography, and pudendal nerve terminal motor latency testing. In this article, the authors describe the physiologic basis for these studies and review the techniques used in diagnosing these conditions.

The role of three-dimensional endoluminal ultrasound imaging in the evaluation of anorectal diseases: a review. Surg Endosc 2008; 22:1570-8. [PMID: 18401655 DOI: 10.1007/s00464-008-9865-4] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2007] [Revised: 12/29/2007] [Accepted: 01/19/2008] [Indexed: 02/07/2023]
Abstract
BACKGROUND The authors conducted a review of the available English literature to evaluate the advantages of three-dimensional ultrasound for assessing anorectal pathology, to provide a state-of-the-art approach, and to compare this technique with conventional endoluminal ultrasound and other imaging methods. METHODS All studies describing results obtained with three-dimensional ultrasound in the evaluation of anorectal pathologies, both alone and compared with other techniques, were selected. RESULTS Since 1996, 32 articles have been published. In tumor staging, specific data derived by three-dimensional reconstruction for the assessment of T invasion and nodal involvement were more accurate than endoluminal ultrasound and computed tomography. For evaluating perianal sepsis, the detection of secondary fistula tracts and fluid collections and the location of internal openings were superior to endoanal magnetic resonance imaging. In the evaluation of anal incontinence, the results for sphincter defects were similar to those obtained with endoanal magnetic resonance imaging. CONCLUSION Analysis of the literature confirmed that three-dimensional ultrasound is a valuable technique for assessing anorectal disorders, facilitating the interpretation of the images obtained, and providing additional data that in many cases have changed the operative approach.

Abstract
AIM To test the effectiveness of echodefecography, the dynamic 3D anorectal ultrasonography technique -(EDF). To assess women with obstructed defecation (OD), as compared with conventional defecography (DF). METHODS A prospective study was carried out with 30 women with OD symptoms, the mean validated Wexner constipation score was 14 (range 7-25) and the mean age 47.7 years. All patients were submitted to DF followed by EDF and the results compared. RESULTS Six patients were normal at DF and five were normal at EDF. Defecography identified grade I rectocele in five patients (average size: 1.8 cm), grade II in seven (average size: 2.9 cm) and grade III in 12 (average size: 4.6 cm). Different sizes of anorectocele were also observed at EDF and quantified according to DF classification (grade I: </=0.6 cm; grade II: 0.7-1.3 cm; grade III: >1.3 cm). Significant differences were observed between anorectocele sizes (p < 0.05) and between normal patients and grade I (p < 0.001). The level of agreement between the techniques was high (kappa = 0.902), with only one normal case wrongly identified as anorectocele III at EDF. Rectal intussusception was identified in five patients at DF; EDF confirmed these cases and revealed seven others, demonstrating moderate agreement (kappa = 0.462). Anismus was identified in nine patients in DF and in eight in EDF (kappa = 0.901). CONCLUSION Echodefecography may be used as an alternative method to assess patients with OD as it has been shown to detect the same anorectal dysfunctions observed in DF. It is minimally invasive, well tolerated, inexpensive, avoids exposure to radiation, and clearly demonstrates all the anatomic structures involved with defecation.
