Abstract
Purpose Constipation is a common entity in society with various factors in the etiology. In this study, we evaluated the role of anal sphincter pressure of patients who refer to surgery clinic with complaint of constipation. Methods Sixty patients who refer to surgery clinic with complaint of constipation and were diagnosed with constipation due to Rome III criteria between July 2010 and September 2014. These patients were evaluated with defecography and were divided into 2 groups based on presence of rectocele. Both groups’ anal sphincter pressures were evaluated using anal manometry and findings were compared. Results The patients with rectocele and without rectocele using defecography were inspected with anal manometry regarding resting tone pressure, squeeze pressure, maximum squeeze pressure and simulated defecation response pressure, first sensation volume, urge sensation volume, and maximum tolerable volume. Results were compared and no significant difference was found regarding groups with rectocele and without rectocele (P > 0.05). Conclusion We have proved the hypothesis arguing that increased sphincter pressures do not play a role in the formation of rectocele by inducing an obstruction and the formation of dilation in proximal bowel, and demonstrated that the presence of rectocele is not dependent on an increase in sphincter pressures.

[PMID: 31828573 DOI: 10.1007/s10151-019-02131-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2018] [Accepted: 11/25/2019] [Indexed: 11/27/2022]
Abstract
BACKGROUND The aim of this study was to evaluate the impact of the transanal repair of rectocele and rectal mucosectomy with a single circular stapler (TRREMS) on the treatment of obstructed defecation due to rectocele and to identify the predictive factors for unsuccessful results. METHODS Consecutive patients with obstructed defecation symptoms (ODS) associated with rectocele who had the TRREMS procedure were included. Each patient was assessed by echodefecography, manometry, and colonic transit time as well as the Cleveland Clinic constipation score (CCS) before therapy and at follow-up after 6 months. Reduction in the CCS score was calculated as a ratio. Factors correlated with a decrease in the CCS were analyzed in a univariate analysis. RESULTS A total of 81 patients were included. Nineteen patients had postoperative complications that were not severe: 7 (8.6%) had tenesmus, 6 (7.4%) stenosis (4 treated with digital dilatation and 2 with endoscopic stricturectomy), 4 (4.9%) residual mucosal prolapse treated with rubber band ligation, 1 (1.2%) early bleeding, and 1(1.2%) thrombosis. Seventy-nine (97.5%) patients had a significant clinical response with significant reduction of the CCS constipation score from median 13 (range 17-10) to 4 (range, 8-2) (p = 0.0001); only 2 patients (2.5%) had an unsatisfactory response, complaining of straining and vaginal digitation during the evacuatory effort. Patients with anismus previously treated with biofeedback had a lower reduction ratio of the CCS score compared with patients without anismus (61.2 ± 2.8% versus 70.9% ± 1.5, p = 0.0006). There were no significant differences in the reduction of the CCS according to age, parity, type of delivery, previous hysterectomy, post-menopausal status, rectal mucosal prolapse and/or associated rectal intussusception, grade of rectocele and presence of complications. CONCLUSIONS The TRREMS procedure significantly improved evacuation disorders in this study. Appropriate selection of patients is key for the success of this approach. Anismus even if previously treated with biofeedback, was the main predictive factor of unsuccessful treatment.

Abstract
BACKGROUND & AIMS Contrary to conventional wisdom, the rectoanal gradient during evacuation is negative in many healthy people, undermining the utility of anorectal high-resolution manometry (HRM) for diagnosing defecatory disorders. We aimed to compare HRM and magnetic resonance imaging (MRI) for assessing rectal evacuation and structural abnormalities. METHODS We performed a retrospective analysis of 118 patients (all female; 51 with constipation, 48 with fecal incontinence, and 19 with rectal prolapse; age, 53 ± 1 years) assessed by HRM, the rectal balloon expulsion test (BET), and MRI at Mayo Clinic, Rochester, Minnesota, from February 2011 through March 2013. Thirty healthy asymptomatic women (age, 37 ± 2 years) served as controls. We used principal components analysis of HRM variables to identify rectoanal pressure patterns associated with rectal prolapse and phenotypes of patients with prolapse. RESULTS Compared with patients with normal findings from the rectal BET, patients with an abnormal BET had lower median rectal pressure (36 vs 22 mm Hg, P = .002), a more negative median rectoanal gradient (-6 vs -29 mm Hg, P = .006) during evacuation, and a lower proportion of evacuation on the basis of MRI analysis (median of 40% vs 80%, P < .0001). A score derived from rectal pressure and anorectal descent during evacuation and a patulous anal canal was associated (P = .005) with large rectoceles (3 cm or larger). A principal component (PC) logistic model discriminated between patients with and without prolapse with 96% accuracy. Among patients with prolapse, there were 2 phenotypes, which were characterized by high (PC1) or low (PC2) anal pressures at rest and squeeze along with higher rectal and anal pressures (PC1) or a higher rectoanal gradient during evacuation (PC2). CONCLUSIONS In a retrospective analysis of patients assessed by HRM, measurements of rectal evacuation by anorectal HRM, BET, and MRI were correlated. HRM alone and together with anorectal descent during evacuation may identify rectal prolapse and large rectoceles, respectively, and also identify unique phenotypes of rectal prolapse.

Abstract
Recent developments in diagnostic imaging have made gynecologists, colorectal surgeons and gastroenterologists realize as never before that they share a common interest in anorectal and pelvic floor dysfunction. While we often may be using different words to describe the same phenomenon (e.g. anismus/vaginismus) or attributing different meanings to the same words (e.g. rectocele), we look after patients with problems that transcend the borders of our respective specialties. Like no other diagnostic modality, imaging helps us understand each other and provides new insights into conditions we all need to learn to investigate better in order to improve clinical management. In this review we attempt to show what modern ultrasound imaging can contribute to the diagnostic work-up of patients with posterior vaginal wall prolapse, obstructed defecation and rectal intussusception/prolapse. In summary, it is evident that translabial/perineal ultrasound can serve as a first-line diagnostic tool in women with such complaints, replacing defecation proctography and MR proctography in a large proportion of female patients. This is advantageous for the women themselves because ultrasound is much better tolerated, as well as for healthcare systems since sonographic imaging is much less expensive. However, there is a substantial need for education, which currently remains unmet.

Abstract
OBJECTIVES Large rectoceles (>2 cm) are believed to be associated with difficulty in evacuation, constipation, rectal pain, and rectal bleeding. The aim of our study was to determine whether rectocele size is related to patient's symptoms or defecatory parameters. METHODS We conducted a retrospective study on data collected on patients referred to our clinic for the evaluation of evacuation disorders. All patients were questioned for constipation, fecal incontinence, and irritable bowel syndrome and were assessed with dynamic perineal ultrasonography and conventional anorectal manometry. RESULTS Four hundred eighty-seven women were included in our study. Rectocele was diagnosed in 106 (22%) women, and rectocele diameter >2 cm in 93 (87%) women. Rectocele size was not significantly related to demographic data, parity, or patient's symptoms. The severity of the symptoms was not correlated to the size or to the position of the rectocele. The diagnosis of irritable bowel syndrome was neither related to the size of the rectocele. Rectocele location, occurrence of enterocele, and intussusception were not related to the size of the rectocele. Full evacuation of rectoceles was more common in small rectoceles (79% vs. 24%, p = 0.0001), and no evacuation was more common in large rectoceles (37% vs. 0, p = 0.01). Rectal hyposensitivity and anismus were not related to the size of the rectocele. CONCLUSION In conclusion, only the evacuation of rectoceles was correlated to the size of the rectoceles, but had no clinical significance. Other clinical, anatomical factors were also not associated to the size of the rectoceles. Rectoceles' size alone may not be an indication for surgery.

Abstract
PURPOSE This report describes the advantages of 3D anal endosonography in depicting the normal anatomy of the anal canal in relation to sex and age. MATERIALS AND METHODS A retrospective study was performed of 85 patients, 33 men and 52 women, previously examined with 3D anal ultrasound (US) for clinically suspected anorectal disease but found to be negative. The examinations were performed with a Bruel and Kjaer US system with a 2050 transducer, scanning from the anorectal junction to the subcutaneous portion of the external anal sphincter (EAS). The 3D reconstructions provided an estimation of sphincter length in the anterior and posterior planes, and axial 2D images enabled calculation of the thickness of the internal anal sphincter (IAS) and EAS in the anterior, posterior and lateral transverse planes. RESULTS Distribution of the sphincter complex is asymmetric in both sexes: the EAS and IAS are significantly shorter in females, especially in the anterior longitudinal plane (p=0.005 and p<0.001, respectively). EAS and IAS thickness increases with age, especially the lateral IAS (R(2)=0.37, p<0.001) and the posterior EAS (R(2)=0.29, p=0.01). CONCLUSIONS A good knowledge of anal-canal anatomy is essential to detect sphincter abnormalities when assessing pelvic floor dysfunction.

Abstract
CONTEXT Since anorectocele is usually associated with mucosa prolapse and/or rectal intussusceptions, it was developed a stapled surgical technique using one circular stapler. OBJECTIVE To report the results of Transanal Repair of Rectocele and Rectal Mucosectomy with one Circular Stapler (TRREMS procedure) in the treatment of anorectocele with mucosa prolapse in a prospective multicenter trial. METHODS It was conducted by 14 surgeons and included 75 female patients, mean aged 49.6 years, with symptoms of obstructed defecation due to grade 2 (26.7%) and grade 3 (73.3%) anorectocele associated with mucosa prolapse and/or rectal intussusception (52.0%) and an average validated Wexner constipation score of 16. All patients were evaluated by a proctological examination, cinedefecography, anal manometry and colonic transit time. The TRREMS procedure consists of the manual removal of the rectocele wall with circumferential rectal mucosectomy performed with a circular stapler. The mean follow-up time was 21 months. RESULTS All patients presented obstructed defecation and they persisted with symptoms despite conservative treatment. The mean operative time was 42 minutes. In 13 (17.3%) patients, bleeding from the stapled line required hemostatic suture. Stapling was incomplete in 2 (2.6%). Forty-nine patients (65.3%) required 1 hospitalization day, the remainder (34.7%) 2 days. Postoperatively, 3 (4.0%) patients complained of persistent rectal pain and 7 (9.3%) developed stricture on the stapled suture subsequently treated by stricturectomy under anesthesia (n = 1), endoscopic stricturectomy with hot biopsy forceps (n = 3) and digital dilatation (n = 3). Postoperative cinedefecography showed residual grade I anorectoceles in 8 (10.6%). The mean Wexner constipation score decreased significantly from 16 to 4 (0-4: n = 68) (6: n = 6) (7: n = 1) (P<0.0001). CONCLUSION Current trial results suggest that TRREMS procedure is a safe and effective technique for the treatment of anorectocele associated with mucosa prolapse. The stapling technique is low-cost as requires the use of a single circular stapler.

Abstract
Background The aim of the present study was to make a preoperative and postoperative clinical and functional evaluation of patients who underwent transanal repair of rectocele and rectal mucosectomy with a single circular stapler (TRREMS procedure) as treatment for obstructed defecation syndrome (ODS) caused by rectocele and rectal mucosal prolapse (RMP). Methods This prospective study included 35 female patients, 34 multiparous and one nulliparous, with an average age of 47.5 years (range 31–67 years), rectocele grade II (n = 13/37.1%) or grade III (n = 22/62.9%), associated with RMP. The study parameters included ODS, constipation, functional continence scores and pre- and postoperative cinedefecographic findings. Results The average preoperative ODS score, the constipation score and the functional continence score were significantly reduced after surgery from 10.63 to 2.91 (p = 0.001), 15.23 to 4.46 (p = 0.001) and 2.77 to 1.71 (p = 0.001), respectively. Between the first and the eighth postoperative day, the average visual analog scale pain score fell from 5.23 to 1.20 (p = 0.001). Satisfaction with treatment outcome was 79.97, 86.54, 87.65 and 88.06 at 1, 3, 6 and 12 months, respectively. Cinedefecography revealed average reductions in rectocele size from 19.23 ± 8.84 mm (3–42) to 6.68 ± 3.65 mm (range 0–7) at rest and from 34.89 ± 12.30 mm (range 20–70) to 10.94 ± 5.97 mm (range 0–25) during evacuation (both P = 0.001). Conclusion The TRREMS procedure is a safe and efficient technique associated with satisfactory anatomic and functional results and with a low incidence of postoperative pain and complications.

Abstract
OBJECTIVE The study aimed to verify the role of parity, age and bowel function in the pathogenesis of anorectocele. METHOD A cross-sectional study was conducted regarding age, obstetrical history, Cleveland Clinic Constipation Score (CCCS), cinedefecography and anal manometry findings. Forty-five adult women complaining of obstructed defecation were evaluated; the median age was 46 years and median CCCS, 13. Fifteen patients were nulliparous and 23 multiparous (median parity 2). Eighteen had a history of episiotomy, fourteen delivered large babies and two had forceps-assisted delivery. Statistical analysis was performed using Spearman's correlation test and Fisher's exact test. RESULTS Anal hypertonia was found in 14 (31.1%) patients, anal hypotonia in eight (17.8%), anismus in 13 (28.9%) and anorectoceles in 34 (75.6%) [median size 2.8 cm (0-6.4)]. There were no correlations between anorectocele and anal hypertonia (P = 0.7171), anismus (P = 0.4666), parity comparing nulliparous and multiparous patients (P = 1.000), episiotomy (P = 1.0000), forceps assistance (P = 1.0000), delivery of a large baby (P = 1.0000) anal resting pressure (P = 0.0883), anal voluntary pressure (P = 0.7327), parity (P = 0.4987) and age (P = 0.8603). There were correlations between anorectocele and the CCCS (P = 0.0082) and anal hypotonia (P = 0.0141). CONCLUSION Anorectocele is not correlated with parity, age, episiotomy, delivery of a large baby and anismus. It was more frequent in patients with severe constipation and less common in patients with anal hypotonia.

Types of pelvic floor dysfunctions in nulliparous, vaginal delivery, and cesarean section female patients with obstructed defecation syndrome identified by echodefecography. Int J Colorectal Dis 2009; 24:1227-32.

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.

Rectocele and intussusception: is there any coherence in symptoms or additional pelvic floor disorders? Tech Coloproctol 2009; 13:17-25; discussion 25-6.

Abstract
BACKGROUND Patients with a rectocele often suffer from such symptoms as obstructed defaecation, urine or stool incontinence and pain. The aim of this study was to assess other concomitant pelvic floor disorders and their influence on pelvic function. METHODS Included in the study were 37 female patients with a significant rectocele and defaecation disorder. Medical history and symptoms were analysed in terms of validated functional scores. All patients underwent open magnetic resonance defaecography (MRD) in a sitting position. Imaging was analysed for the presence and size of the rectocele, intussusception and other pelvic floor disorders. RESULTS Patients with a higher body mass index tended to have a larger rectocele, whereas age and vaginal birth did not correlate with the size of the rectocele. In 67.5% of the patients with a previously diagnosed rectocele, an intussusception was diagnosed on MRD. This group suffered from significantly worse urine incontinence (p=0.023) and from accessory enteroceles 64%, compared with 17% (p=0.013) for those with a simple rectocele. Patients with higher grade intussusception suffered more frequently from incontinence than from constipation. CONCLUSION Patients with a symptomatic rectocele frequently have other pelvic floor disorders that significantly influence the pattern of symptoms. Knowledge of all the afflictions is essential for determining the optimal treatment for each individual patient.

Abstract
The purpose of this study was to assess the impact of new technology on both the understanding of the underlying pathophysiology and treatment of solitary rectal ulcer syndrome (SRUS). This study is a retrospective review of patients with a histologic diagnosis of SRUS (1993 to 2007) complimented with a prospective database of those patients studied with defecography and dynamic pelvic MRI. Thirty patients were available for evaluation. A polyp or mass was present in 74 per cent. Ulcers were found in only 23 per cent. All 12 patients undergoing defecography demonstrated rectorectal intussusception. Dynamic MRI of the pelvis revealed pronounced anorectal redundancy and lack of mesorectosacral fixation with mild to severe pelvic floor descent in all four patients studied. Fiber with or without stool softeners was the initial treatment in all patients with resolution of symptoms in 65 per cent. One patient with refractory symptoms underwent a stapled transanal rectal resection with complete resolution of symptoms. Occult rectorectal intussusception appears to be the operant anatomic pathology in SRUS. Anorectal redundancy with lack of mesorectosacral fixation may contribute to the process. All patients should be studied with defecography and dynamic MRI. Stapled transanal rectal resection may offer a promising surgical option.

Abstract
Endoanal ultrasound is a well-established technique used to evaluate benign anorectal disorders. The technique is easy to perform, has a short learning curve and causes very little discomfort. Reconstruction of 3D images is possible. The clinical indications for endoanal ultrasound in benign anorectal diseases are fecal incontinence and peri-anal fistula. Sphincter defects can be depicted with precision and correlate perfectly with surgical findings. Furthermore, an impression of sphincter atrophy can be established. With perianal fistula the tracts can be visualized. Introducing hydrogen peroxide via the external fistula opening improves imaging. Endoanal ultrasound and MRI have comparable results in diagnosing anorectal disorders.

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.

A novel three-dimensional dynamic anorectal ultrasonography technique (echodefecography) to assess obstructed defecation, a comparison with defecography. Surg Endosc 2007; 22:974-9. [PMID: 17705074 DOI: 10.1007/s00464-007-9532-1] [Citation(s) in RCA: 62] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2007] [Revised: 06/22/2007] [Accepted: 07/07/2007] [Indexed: 12/24/2022]
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.

Abstract
BACKGROUND Demonstrate precisely the anatomic configuration of the anal canal and the length and thickness of the anal sphincters using three-dimensional (3-D) anorectal ultra-sonography in both genders. METHODS Twelve normal volunteer males and 14 females, with a mean age of 52.4 and 50.3 years, respectively, were prospectively enrolled in this study. All individuals from both groups were submitted to anorectal ultra-sonography. The anal canal was analyzed, measuring the length and thickness of the external anal sphincter (EAE), internal anal sphincter (IAS), puborectalis muscle (PR) and the gap (distance from the anterior EAS to the anorectal junction) in the midline longitudinal (ML) and transverse (MT) planes, and the results were compared between quadrants and genders. RESULTS The distribution of sphincter muscles is asymmetric in both genders. The anterior upper anal canal is an extension of the rectal wall with all layers clearly identified. The anterior IAS is formed in the distal upper anal canal and is significantly shorter in female than in male in all quadrants. The anterior IAS length is shorter than the posterior and lateral in both genders. The anterior EAS length is significantly shorter (2.2 cm) and the gap is longer (1.2 cm) in female than in male (3.4 cm) (0.7 cm) (p < 0.05), respectively. The posterior and lateral EAS-PR is significant longer in males (3.6 cm) (3.9 cm) than in females (3.2 cm) (3.5 cm) (p < 0.05), respectively. The lateral EAS-PR is significant longer than the posterior part in both genders. The anterior IAS is significantly thicker in males (0.19 cm) than in females (0.12 cm) (p = 0.04). CONCLUSION 3-D anal endosonography enabled measurement of the different anatomical structures of the anal canal and demonstrated its asymmetrical configuration. The shorter anterior EAS and IAS associated with a longer gap could justify the higher incidence of pelvic floor dysfunction in females, especially fecal incontinence and anorectocele with rectal intussusception.

Abstract
OBJECTIVE This study aimed to determine the value of three-dimensional (3D) dynamic endosonography in the assessment of anismus. METHOD Sixty-one women submitted to anorectal manometry were enrolled including 40 healthy women and 21 patients with anismus diagnosed by manometry. Patients were submitted to 3D endosonography. Images were acquired at rest and during straining and analysed in axial and midline longitudinal planes. Sphincter integrity was quantified. The angle between the internal edge of the puborectalis with a vertical line according to the anal canal axis was calculated at rest and during straining. RESULTS The angle increased in 39 of the 40 normal individuals and decreased in all patients with anismus during straining compared with the angle at rest (88.36 degrees ) and straining (98.65 degrees ) in normal individuals. In the anismus group, the angle decreased at rest (90.91 degrees ) and straining (84.89 degrees ). The difference between angle sizes in normal and anismus patients during straining was statistically significant (P < 0.5). CONCLUSION Three-dimensional endosonography is a useful method to assess patients with anismus confirming the anorectal manometric results.
