Comparison of etiological and physiological characteristics of fecal incontinence in men and women.

Fecal incontinence (FI) is often underreported and underestimated in men. Our aims were to clarify the causes and the physiological characteristics of FI in men and to underline the differences between etiological and physiological factors in men and women diagnosed with FI. The study cohort encompassed 200 men and 200 women who underwent anatomical and physiological evaluation for FI in a tertiary referral center specializing in pelvic floor disorders. All patients underwent endoanal ultrasound and anorectal manometry. Evacuation proctography was performed in some patients. Demographic, medical, anatomical, and physiological parameters were compared between the two study groups. Urge incontinence was the most frequent type of FI in both genders. In men, anal fistula, history of anal surgeries, rectal tumors, and pelvic radiotherapy were common etiologic factors, whereas history of pelvic surgeries was more common in women. Associated urinary incontinence was reported more frequently by women. External anal sphincter defects, usually anterior, were more common in women (M: 1.5%, F: 24%, P < 0.0001), whereas internal anal sphincter defect prevalence was similar in men and women (M: 6%, F: 12%, P = 0.19). Decreased resting and squeeze pressures were less common in men (M: 29%, F: 46%, P < 0.0001: M: 44%, F: 66%, P < 0.0001). The incidence of rectal hyposensitivity was higher in men (M: 11.1%, F: 2.8%, P < 0.0001), whereas rectal hypersensitivity was higher in women (M: 5.8%, F: 10.8%, P < 0.0001). Anorectal dyssynergia was more common in men (M: 66%, F: 37%, P < 0.0001). Significantly different etiological factors and physiological characteristics for FI were found in men. Acknowledging these differences is significant and may yield better treatment options.NEW & NOTEWORTHY Fecal incontinence (FI) in men has different etiological factors when compared with women. The prevalence of internal anal sphincter defect among men with FI was similar to women. Different manometric measurements were found among men with FI: decreased anal pressures were less common among men, whereas rectal hyposensitivity and anorectal dyssynergia were more common among men.

Centrally Distributed Adiposity as a Modifiable Risk Factor for Fecal Incontinence: United States Population-based Analysis.

BACKGROUND AND AIMS: Fecal incontinence (FI) is highly prevalent with substantial impacts on quality of life and health care utilization. The impact of obesity on FI remains unclear, with differing conclusions using body mass index (BMI) as a risk factor. We aimed to determine the association between obesity and FI, and whether this relationship is dependent on the distribution of adiposity (waist circumference-to-height ratio [WHtR]). METHODS: This was a population-based analysis of the National Health and Nutrition Examination Survey, including participants who responded to the bowel health survey in 2005 to 2010. FI was defined by the accidental bowel leakage of solid stool, liquid, or mucus at least once in the past month. Stepwise multivariable logistic regression models were constructed to assess risk factors for FI. RESULTS: A total of 7606 participants were included, with an overall FI prevalence of 9.2%. When stratified by quartiles of body measurements, FI was increasingly prevalent from the 1st to the 4th quartile for both WHtR (range, 5.3%-12.5%) and BMI (range, 7.1%-10.5%). WHtR was associated with FI and was a stronger predictor than BMI in all quartiles of body measurement. On multivariable analysis, WHtR remained a significant predictor of FI comparing the 4th with the 1st quartile of body measurements (odds ratio [OR], 1.77; 95% confidence interval [CI], 1.11-2.80; P = .017), whereas BMI was not. A WHtR cutoff of >0.592 optimized the Youden index in prediction of FI in the overall sample. CONCLUSION: WHtR was independently associated with increased odds of FI in this nationally representative sample of United States adults, whereas BMI was not consistently correlated. This suggests bowel continence may depend more on how body mass is distributed.

Fecal incontinence is not associated with UTI: A contemporary case-control study.

INTRODUCTION: Urinary tract infections (UTIs) are a leading cause of infection in adults. The most common cause is gastrointestinal bacteria ascending the urethra into the bladder. Studies showing fecal incontinence (FI) is a risk factor for UTI have been limited to nursing home populations. Healthy patients with recurrent UTI, especially women, often receive counseling, suggesting improper personal hygiene contributes to UTIs. This advice can be stigmatizing. Given UTI prevalence, it is important to elucidate risk factors for improved diagnosis, treatment, and patient education. Our objective was to perform a hospital-centered, retrospective case-control analysis to assess the effect of FI on UTI development in ambulatory patients. METHODS: Patients (n = 3035) with a diagnosis of FI were identified from a single institution and propensity score-matched with screening colonoscopy patients (n = 3035) from 2018 to 2021. Patients were matched on age, sex, race, ethnicity, body mass index, and comorbidities, for example, diabetes, vesicoureteral reflux, and urinary incontinence. The association between FI and UTI was tested using Pearson's χ2 test. RESULTS: Median age was 64 years with more females than males (73.81% vs. 71.20% female for case/control, p = 0.02). Patients with FI were more often to have concurrent urinary incontinence (18.62% vs. 10.25% for case/control, p < 0.001), as well as specifically urgency incontinence (13.28% vs. 11.57% for case/control, p = 0.04). There was no significant difference in the incidence of UTI between patients with FI and those presenting for screening colonoscopy (p = 0.44). CONCLUSION: FI was not associated with an increased number of UTIs. Based on our results, current stigmatizing beliefs regarding the association between FI and UTI should be reevaluated.

The association of fecal incontinence, constipation, and pelvic pain with the course of lower urinary tract symptoms in community-dwelling men and women.

BACKGROUND: Fecal incontinence, constipation, and pelvic pain are common pelvic floor symptoms (PFS), and frequently coexist with lower urinary tract symptoms (LUTS). However, their association with the longitudinal trajectory of LUTS have not been well described. Our objective was to investigate the association between PFS and the course of LUTS in community-dwelling men and women. METHODS: Men and women aged ≥16 years were invited to participate in a prospective observational cohort study. At baseline, and after 12 and 24 months, participants filled in the International Consultation on Incontinence Modular Questionnaire (ICIQ-MLUTS and ICIQ-FLUTS) for men and women respectively, the Wexner incontinence and constipation scale, and a questionnaire on pelvic pain. Generalized estimating equations were used to examine the association between change scores in defecation problems and pelvic pain, and LUTS change scores. RESULTS: A total of 694 men and 997 women gave informed consent, with 417 men and 566 women included in the analysis. The mean age was 63.2 ± 12.7 years for men and 58.6 ± 14.8 years for women. The study showed minor changes in LUTS scores over the 0-12 and 12-24-month periods. Generalized estimating equations revealed positive associations between changes in constipation and fecal incontinence and LUTS changes in both sexes. For instance, a one-point increase in Wexner constipation score was associated with 0.376 (0.165, 0.587) points higher LUTS change in men and 0.223 (0.109, 0.336) points in women during the 0-12-month follow-up. However, associations between changes in pain and LUTS scores varied across sexes and time periods. CONCLUSIONS: We observed minor changes in LUTS over time and weak associations between PFS and LUTS that sometimes differed between males and females, emphasizing the need for sex-specific considerations. These insights can provide valuable guidance for the development of targeted prevention trials, ultimately aiming to enhance overall pelvic health and patient well-being.

Exploring the association between type 2 diabetes and fecal incontinence in american adults: insights from a large cross-sectional study.

BACKGROUND: The relationship between fecal incontinence (FI) and type 2 diabetes (T2D) has been well recognized, but a comprehensive understanding of this relationship is lacking, taking into account demographic factors and lifestyle variables. METHODS: Using a cross-sectional approach, 13,510 adults aged 20 years and older were identified from the 2005-2010 National Health and Nutrition Examination Survey. Multivariate logistic regression models were used to calculate the adjusted odds ratios (ORs), and further subgroup analyses and propensity score analysis were performed to ensure stable results. RESULTS: Among 13,510 adults, 11.2% had T2D, and 8.8% had FI. We found a strong T2D-FI link (OR: 1.30; 95% CI: 1.09-1.54, P < 0.001), even after adjusting for covariates. Age > 45 was a critical factor, with a stronger T2D-FI association. Sedentary behavior (OR: 1.41; 95% CI: 1.15-1.73) in T2D patients were associated with FI. CONCLUSIONS: Our study highlights the significant T2D-FI link in US adults, especially in older T2D patients. Lifestyle changes may reduce FI risk. More research is needed for causality and mechanisms.

Infracoccygeal/transperineal window: new method to prenatally diagnose and classify level of anal atresia.

OBJECTIVES: To introduce a two-dimensional sonographic method to assess the fetal anus, and to evaluate the feasibility of this method to diagnose anal atresia prenatally and identify the presence or absence of anoperineal fistula (in males) and anovestibular fistula (in females). METHODS: This was an observational study of suspected cases of anal atresia referred to a single center in Israel between August 2018 and October 2023. In addition to conventional evaluation of the perineum in the axial plane, fetuses referred to our center for suspected malformation were scanned with a new method termed the 'infracoccygeal/transperineal window'. This window consisted of a midsagittal view of the fetal pelvis, including the distal rectum and the anal canal. Normal anatomy was confirmed when the anal canal was continuous with the rectum and terminated at the expected location on the perineum. In female fetuses, the normal anal canal runs parallel to the vaginal canal and diverges posteriorly, terminating at the perineal skin, distant from the vestibule. In male fetuses, the normal anal canal diverges posteriorly in relation to the corpora cavernosa, terminating at the perineal skin, distant from the scrotum. High anal atresia was identified when a blind-ending rectal pouch was demonstrated in the pelvis without a fistula to the perineum or vestibule. Low anal atresia was determined when a rectal pouch was continuous with an anteriorly deflected fistula. In females, the fistula converges with the vaginal canal, terminating at the vestibule; in males, the fistula deflects anteriorly, terminating at the base of the scrotum. Postnatally, the diagnosis and type of anal atresia were confirmed through physical examination with direct visualization of the fistula, radiographic studies, surgical examination and/or postmortem autopsy. RESULTS: Of the 16 fetuses diagnosed prenatally with anal atresia, eight were suspected to have low anal atresia and eight were suspected to have high anal atresia. The median gestational age at diagnosis was 23 (range, 14-37) weeks. All cases showed additional structural malformation. Eleven patients opted for termination of pregnancy, of which four had low anal atresia and seven had high anal atresia. Postnatal confirmation was not available in four cases due to curettage-induced mutilation or in-utero degradation following selective termination of the affected twin, leaving 12 cases for analysis, of which seven were diagnosed with low anal atresia and five with high anal atresia. In these 12 cases, all prenatal diagnoses were confirmed as correct, rendering 100% sensitivity and 100% specificity in this high-risk fetal population. CONCLUSIONS: The infracoccygeal/transperineal window is an effective method to detect and classify the level of anal atresia prenatally. This may improve prediction of postnatal fetal continence and optimize prenatal counseling. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Relation between the internal anal sphincter and defecation disorders in patients with anorectal malformations.

OBJECTIVES: To investigate associations between the rectoanal inhibitory reflex (RAIR), type of congenital anorectal malformations (ARMs), type of operation that patients with ARM had undergone, and objectively measured fecal incontinence and defecation problems. METHODS: We retrospectively included 69 pediatric patients with ARM. All underwent anorectal function tests at the University Medical Center of Groningen during the last 10 years. We assessed anorectal physiology using the Rome IV criteria and anorectal function tests. RESULTS: We found the reflex in 67% of patients and all types of ARMs. All patients who had not been operated on, and those who had undergone less extensive surgery possessed the reflex. In contrast, patients who underwent posterior sagittal anorectoplasty, 44% possessed it. We found no difference between mean rectal volumes in patients with and without the reflex (251 vs. 325 mL, respectively, p = 0.266). We found that over time, patients without the reflex seemed to develop significantly higher rectal volumes than patients who had it. We did not find a significant difference between the reflex and fecal incontinence; however, it seems that the absence of the reflex, resting anal sphincter pressure, and fecal incontinence are related. CONCLUSION: The RAIR seems present in patients with ARM irrespective of their malformation type. Corrective surgery, however, may impair this reflex. Seemingly, its absence results in constipation with enlarged rectal volumes and fecal incontinence. Every effort should be made to preserve this reflex during surgery and to use extensive surgical procedures as sparingly as possible.

Utility of colonic manometry in children with Hirschsprung disease.

OBJECTIVES: Abnormal motility of the residual colon has been reported in post-pull-through Hirschsprung disease (PT-HSCR) patients with persistent defecation problems. We reviewed the role of colonic manometry (CM) in the management of defecation disorders in these patients. METHODS: We retrospectively reviewed the medical record of PT-HSCR children who underwent CM for persistent symptoms of abnormal defecation. We reviewed their clinical course and its relation to CM findings. RESULTS: Thirty PT-HSCR patients underwent CM, of which five were diagnosed with transition zone pull-through and were excluded. Of the remaining 25 patients, 16 had colonic dysmotility, 8 had normal CM, and one had colonic hypermotility. In patients with dysmotility, five responded to ongoing medical management, three required surgical intervention (ileostomy), three remained symptomatic with medical management but not yet received surgical intervention, and five were lost to follow-up. In patients with normal CM, four responded to ongoing medical therapy, two required additional surgery (antegrade enema procedure), and two were lost to follow-up. The patient with hypermotility improved with adding loperamide. CONCLUSIONS: Colonic dysmotility can occur in PT-HSCR patients with persistent defecation problems. CM was helpful in delineating the degree of colonic neuromuscular dysfunction. CM results were used in conjunction with other clinical data to determine optimal management. Our findings support that medical management should first be optimized before consideration of colonic manometry and surgical interventions.

The effectiveness of physiotherapy interventions on fecal incontinence and quality of life following colorectal surgery: a systematic review and meta-analysis of randomized controlled trials.

PURPOSE: To investigate the effectiveness of physiotherapy interventions compared to control conditions on fecal incontinence (FI) and quality of life (QoL) following colorectal surgery. METHODS: Electronic searches in English-language (Scopus, Web of Science, Embase, AMED, CENTRAL, CINAHL, MEDLINE, Ovid, and PEDro) and Chinese-language (CNKI, Wanfang Data) databases were conducted. Trials comparing physiotherapy interventions against control conditions and assessing FI and QoL outcomes were included in the review. RESULTS: Ten trials were included. Meta-analysis revealed statistically significant improvements in lifestyle (0.54; 95% CI 0.03, 1.05; p = 0.04), coping behavior (MD 1.136; 95% CI 0.24, 2.04; p = 0.01), and embarrassment (0.417; 95% CI 0.14, 0.70; p = 0.00) components of QoL among individuals receiving pelvic floor muscle training (PFMT) compared with those receiving usual care (UC). Meta-analysis showed biofeedback to be significantly more effective than UC in enhancing anal resting pressure (ARP; 9.551; 95% CI 2.60, 16.51; p = 0.007), maximum squeeze pressure (MSP; 25.29; 95% CI 4.08, 48.50; p = 0.02), and rectal resting pressure (RRP; 0.51; 95% CI 0.10, 0.9; p = 0.02). Meta-analysis also found PFMT combined with biofeedback to be significantly more effective than PFMT alone for ARP (3.00; 95% CI 0.40, 5.60; p = 0.02), MSP (9.35, 95% CI 0.17, 18.53; p = 0.05), and RRP (1.54; 95% CI 0.60, 2.47; p = 0.00). CONCLUSIONS: PFMT combined with biofeedback was more effective than PFMT alone, but both interventions delivered alone were superior to UC. Future studies remain necessary to optimize and standardize the PFMT parameters for improving QoL among individuals who experience FI following CRC surgery. REVIEW REGISTRATION: This systematic review is registered in the PROSPERO registry (Ref: CRD42022337084).

Pelvic Floor Disorders Due to Anal Sexual Activity in Men and Women: A Narrative Review.

Recent evidence shows that consensual anal penetrative intercourse has become more prevalent, not only limited to gay, bisexual, and other men who have sex with men but also for women who are in a sexual relationship with men. The aim of this review was to study the influence of consensual anal intercourse on pelvic floor function and the role of pelvic floor physical therapy treatment in preventing or treating consensual anal intercourse-induced anodyspareunia and/or fecal incontinence. We reviewed 68 references that showed that anal penetrative intercourse is a risk factor for anodyspareunia and fecal incontinence in both men and women. This risk of anal intercourse may increase with emotional discomfort, an overactive pelvic floor, lack of lubrication, frequency of anal penetrative intercourse, and hard practice (BDSM: bondage and discipline, dominance and submission, sadism, and masochism). It seems that pelvic floor physical therapists play an essential role in preventing and treating pelvic floor dysfunctions due to anal intercourse, which can lead to anodyspareunia and fecal incontinence; the treatment includes education, pelvic floor training with and without biofeedback, electric stimulation, manual therapy, and dilatators. Further studies are warranted to enhance our understanding of the causes and treatment efficacy of pelvic floor dysfunctions due to anal penetrative intercourse.

Dietary Intake and Symptom Severity in Women with Fecal Incontinence.

INTRODUCTION AND HYPOTHESIS: The goal of this study was to determine whether dietary fat/fiber intake was associated with fecal incontinence (FI) severity. METHODS: Planned supplemental analysis of a randomized clinical trial evaluating the impact of 12-week treatment with percutaneous tibial nerve stimulation versus sham in reducing FI severity in women. All subjects completed a food screener questionnaire at baseline. FI severity was measured using the seven-item validated St. Mark's (Vaizey) FI severity scale. Participants also completed a 7-day bowel diary capturing the number of FI-free days, FI events, and bowel movements per week. Spearman's correlations were calculated between dietary, St. Mark's score, and bowel diary measures. RESULTS: One hundred and eighty-six women were included in this analysis. Mean calories from fats were 32% (interquartile range [IQR] 30-35%). Mean dietary fiber intake was 13.9 ± 4.3 g. The percentage of calories from fats was at the higher end of recommended values, whereas fiber intake was lower than recommended for adult women (recommended values: calories from fat 20-35% and 22-28 g of fiber/day). There was no correlation between St. Mark's score and fat intake (r = 0.11, p = 0.14) or dietary fiber intake (r = -0.01, p = 0.90). There was a weak negative correlation between the number of FI-free days and total fat intake (r = -0.20, p = 0.008). Other correlations between dietary fat/fiber intake and bowel diary measures were negligible or nonsignificant. CONCLUSION: Overall, in women with moderate to severe FI, there was no association between FI severity and dietary fat/fiber intake. Weak associations between FI frequency and fat intake may suggest a role for dietary assessment in the evaluation of women with FI.

Correlation of Digital Rectal Examination and Anorectal Manometry with Patient-Reported Outcomes Among Women with Fecal Incontinence.

INTRODUCTION AND HYPOTHESIS: Standardized digital rectal examination (DRE) correlates with anorectal manometry (ARM) measures. However, less is known about the relationship between DRE/ARM measures and patient-reported outcomes (PROs), especially among women with fecal incontinence (FI). Our aims were to evaluate associations between DRE and ARM measures and compare PROs with diagnostic evaluation measures for women with FI. METHODS: We analyzed data from the parent clinical trial, Controlling Anal incontinence by Performing Anal exercises with Biofeedback or Loperamide (CAPABLe). We pooled data from randomized women who completed standardized ARM, DRE, and validated PROs at baseline and 12 and 24 weeks post-treatment initiation. PROs included FI severity, impact on quality of life, and bowel diary data. We analyzed ARM pressure and volume data and DRE using the Digital Rectal Examination Scoring System (DRESS) resting and squeeze mean scores. We used Spearman Rank Correlation to measure associations between the ARM measures and mean DRESS scores, and between PROs and ARM/DRESS scores. RESULTS: Among 291 randomized women with ARM and DRE data, the correlation between DRESS and ARM resting measures was 0.196 (p<0.001) and between squeeze measures was 0.247 (p<0.001). At most timepoints, PROs more consistently correlated with squeeze ARM pressures and squeeze DRESS scores than resting measures. CONCLUSIONS: We found weak correlations between ARM and DRE measures and between those measures and PROs. Although DRE and ARM are commonly used diagnostic measures among women with FI, the weak correlations with patient-reported symptoms raises questions about their utility in clinical care.

Effect of Single-Dose Imipramine on Anal Sphincter Tone in Healthy Women: A Randomized, Placebo-Controlled Study Using Anal Acoustic Reflectometry.

INTRODUCTION AND HYPOTHESIS: Despite the high prevalence of fecal incontinence, existing treatment options may be inadequate. Drugs that enhance the tone of the anal sphincter complex could potentially be an effective pharmacological approach. This study investigated the effect of the tricyclic antidepressant imipramine on anal sphincter tone in healthy women, employing anal acoustic reflectometry as the evaluating method. METHODS: In a double-blind, randomized, placebo-controlled crossover study, 16 healthy female volunteers were randomized to one of two treatment sequences. The participants attended two study visits separated by at least 7 days' washout. At each visit, they received a single dose of 50 mg imipramine or matching placebo, in alternating order. We assessed the anal opening pressure under the resting state and during voluntary squeezing of the pelvic floor. Measurements were performed pre-dose and 1 h after drug administration, corresponding to the estimated time of peak plasma concentration of imipramine. RESULTS: All participants completed the study. In total, 44% of the participants reported at least one adverse effect, primarily anticholinergic. Compared with placebo, imipramine increased anal opening pressure by 15.2 cmH2O (95% confidence interval [CI] 2.0-28.2 cmH2O, p = 0.03) in the resting state and 15.1 (95% CI 4.2-26.0 cmH2O, p = 0.01) cmH2O during squeezing. CONCLUSIONS: The findings indicate that imipramine increases anal sphincter tone in healthy women. However, further research is required to evaluate its clinical impact on individuals with fecal incontinence. This research also demonstrates the effectiveness of using anal acoustic reflectometry for assessing pharmacological effects on anal sphincter function.

Low-Value Practices for Pelvic Floor Dysfunction-Choosing Wisely Recommendations from the Brazilian Association of Physiotherapy in Women's Health: Observational Study.

INTRODUCTION AND HYPOTHESIS: The Choosing Wisely campaign is an international initiative that is aimed at promoting a dialog between professionals, helping the population to choose an evidence-based, truly necessary and risk-free care. The aim of the study was to develop the Choosing Wisely Brazil list on Women's Health Physiotherapy in the area of the pelvic floor. METHODS: A observational study was carried out between January 2022 and July 2023, proposed by the Brazilian Association of Physiotherapy in Women's Health, and developed by researchers working in the area of the pelvic floor. The development of the list consisted of six stages: a panel of experts, consensus building, national research, a review by the Choosing Wisely Brazil team, preparation of the list, and publication of the recommendations. Descriptive and content analyses were carried out in order to include evidence-based recommendations with over 80% agreement by physiotherapists in Brazil. RESULTS: The expert panel was made up of 25 physiotherapists who submitted 63 recommendations. Seven physiotherapists/researchers carried out a critical analysis of the literature and refined the recommendations, resulting in 11 recommendations that were put to a national vote, in which 222 physiotherapists took part. After a review by the Choosing Wisely Brazil team, five recommendations with an average agreement of 88.2% agreement were chosen for publication. CONCLUSIONS: The Choosing Wisely Brazil team in Physiotherapy in Women's Health/Pelvic Floor proposed a list of five recommendations that showed a high agreement among Brazilian physiotherapists working in the area.

Correlation Between Mobile-Application Electronic Bowel Diary and Validated Questionnaires in Women with Fecal Incontinence.

INTRODUCTION AND HYPOTHESIS: Despite growing interest in a mobile-app bowel diary to assess fecal incontinence (FI) symptoms, data are limited regarding the correlation between mobile-app diary and questionnaire-based outcomes. The primary aim is to determine whether percentage reduction in FI episodes (FIEs)/week recorded on a mobile-app diary correlates with changes in scores of validated FI-symptom measures from baseline to 12 weeks in women with FI undergoing percutaneous tibial nerve stimulation (PTNS) versus sham. METHODS: This is a planned secondary analysis of a multicenter randomized trial in which women with FI underwent PTNS or sham. FIEs were collected using a mobile-app diary at baseline and after 12 weekly sessions. FI-symptom-validated measures included St. Mark's, Accidental Bowel Leakage Evaluation, FI Severity Index (FISI), Colorectal Anal Distress Inventory, Colorectal Anal Impact Questionnaire, FI Quality of Life, Patient Global Impression of Improvement (PGI-I), and Patient Global Symptom Control (PGSC) rating. Spearman's correlation coefficient (ρ) was computed between %-reduction in FIEs/week and change in questionnaire scores from baseline to 12 weeks. Significance was set at 0.005 to account for multiple comparisons. RESULTS: Baseline characteristics of 163 women (109 PTNS, 54 sham) include mean age 63.4±11.6, 81% white, body mass index 29.4±6.6 kg/m2, 4% previous FI surgeries, 6.6±5.5 FIEs/week, and St. Mark's score 17.4±2.6. A significant correlation was demonstrated between %-reduction in FIEs/week and all questionnaires (p<0.005). A moderate-strength correlation (|ρ|>0.4) was observed for St. Mark's (ρ=0.48), FISI (ρ=0.46), PGI-I (ρ=0.51), and PGSC (ρ=-0.43). CONCLUSIONS: In women with FI randomized to PTNS versus sham, a moderate correlation was noted between FIEs measured via mobile-app diary and FI-symptom-validated questionnaire scores.

Brazilian Portuguese Translation and Validation of the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire-IUGA revised.

INTRODUCTION AND HYPOTHESIS: Condition-specific sexual questionnaires are important patient-reported outcome measures. The aim of this study was to translate and validate the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire-International Urogynecology Association Revised (PISQ-IR) into Brazilian Portuguese and to clinically validate it in a Brazilian Portuguese-speaking population. METHODS: Translation and validation of the PISQ-IR was performed according to the International Urogynecological Association-recommended process and guidelines. For external validity, PISQ-IR subscales were compared with the clinical measures, Pelvic Organ Prolapse Quantification system (POP-Q) stage, pelvic floor muscle tone, and Oxford Grading Scale (Pearson correlations). Descriptive statistics, internal consistency (Cronbach's alpha coefficient), and test-retest reliability (interclass correlation coefficient) were calculated for all PISQ-IR subscales. RESULTS: A total of 120 sexually active and 106 not sexually active women were enrolled in the study between March 2015 and July 2019. Internal consistency was acceptable, with Cronbach's alpha values 0.60-0.80, except for the sexual arousal and orgasm, sexual arousal and partner-related issues, sexual arousal and condition-specific issues, global rating of sexual quality and condition impact subscales. PISQ-IR demonstrated good reliability (α > 0.6, CIC = 0.996). The agreement for each individual questionnaire item also individually presented substantial agreement between the assessments (κ 0.61-0.8). There was a correlation between PISQ-IR and POP, mixed, stress and fecal incontinence diagnosis and a positive correlation with pelvic floor muscle function according to the Oxford Scale in sexually active women. For sexually inactive women there was a correlation between PISQ-IR and mixed urinary symptoms. CONCLUSIONS: The Brazilian Portuguese version of PISQ-IR is a reliable and valid tool that can be easily used for the identification and assessment of sexual function in Brazilian Portuguese-speaking women with pelvic floor disorders.

Systematic Review and Meta-analysis of the Prevalence of Levator Ani Avulsion with Obstetric Anal Sphincter Injury and its Effects on Pelvic Floor Dysfunction.

INTRODUCTION AND HYPOTHESIS: The objective was to evaluate the prevalence of levator ani avulsion (LAA) among primiparous women with obstetric anal sphincter injury (OASI) and how this association could affect future pelvic floor dysfunction. METHODS: Three electronic databases (MEDLINE/PubMed/EMBASE) were searched in December 2018 and again in October 2022. Nine full-text articles were included in the analysis. The exclusion criteria were language other than English, studies not based on primiparous women only, conference abstracts, and evaluation without ultrasound or MRI. RESULTS: The overall prevalence of LAA was 24% (95% CI: 18-30%). Those with OASI, were at a higher risk of LAA, OR 3.49 (95% CI: 1.46 to 8.35). In women with LAA + OASI versus OASI alone, Three of Five studies showed worsened AI symptoms. Three of Five studies assessing urinary incontinence (UI) reported no significant difference in UI, whereas two reported increased UI. All studies that looked at pelvic organ prolapse reported a higher incidence of symptomatic prolapse and reduced pelvic floor muscle strength in women with LAA + OASI compared with those without LAA. CONCLUSION: Levator ani avulsion is prevalent following vaginal birth and is strongly associated with OASI. Incidence of AI does not increase in women with LAA and OASI, but they had greater symptom bother. OASI with LAA appears to increase the incidence of pelvic floor weakness and pelvic organ prolapse. There is no consensus agreement on the effect of LAA + OASI on UI.

Prevalence and associated factors of symptomatic pelvic floor disorders among women living in Debre Tabor Town, Northwest Amhara, Ethiopia.

BACKGROUND: Pelvic floor disorders are a group of disorders affecting the pelvic floor that include clinically definable conditions such as pelvic organ prolapse, urinary incontinence and fecal incontinence. These conditions silently affect millions of women worldwide and related problems are not well disclosed by women due to associated social stigma or lack of access to services in developing countries. Thus, the magnitude and related burden of these conditions vary, and little is known about them. This study was conducted to assess the magnitude and associated factors of symptomatic pelvic floor disorders in Debre Tabor town, Northwest, Ethiopia, from May 30-July 30, 2020. METHOD: A community-based cross-sectional study was conducted on child bearing women (> 15 years) who resided in Debre Tabor Town from May 30-July 30, 2020. The participants were selected through multistage systematic random sampling. The data were collected via a structured questionnaire through face-to-face interviews, entered into Epi-info-7.2, and subsequently analyzed using SPSS version 20. The prevalence of pelvic floor disorders was presented along with the 95% CI. RESULTS: A total of 402 women participated in this study, 59 (14.7%; 95% CI; 11.4, 18.2) of whom reported one or more types of pelvic floor disorders. The most prevalently reported pelvic floor disorders were pelvic organ prolapse (13.9%; 95% CI: 10.9, 17.4), urinary incontinence (10.9%; 95% CI: 7.4, 9.2) and fecal incontinence (7.7%; 95% CI: 5.2, 10.2). Additionally, aging, multiparity and having early marriage (< 18 yrs.) were identified as potential risk factors associated with pelvic floor disorders. CONCLUSIONS: The prevalence of symptomatic pelvic floor disorders in the current study was high. Thus, early detection, preventive and treatment strategies should be considered. In addition, it is better to educate the community and women on the association of early marriage and multiparty with PFDs.

Experimental evaluation of an artificial anal sphincter based on biomechanical compatibility.

BACKGROUND: The artificial anal sphincter is a device used to treat patients with fecal incontinence who are unable to control their bowel movements on their own. Long-term morphological changes in the tissue surrounding the artificial anal sphincter can cause biomechanical compatibility problems, which seriously affect the clinical application of the artificial anal sphincter. METHODS: In this paper, the superelasticity of shape memory alloys was utilized to design and fabricate a biomechanically compatible constant force clamping artificial anal sphincter. An in vitro simulation system was constructed to verify the effectiveness, safety, and constant force characteristics of the artificial anal sphincter. RESULTS: The experimental results demonstrated that the artificial anal sphincter could be effectively closed with no leakage of the liquid-like intestinal contents, which are most likely to leak. The pressure of the artificial anal sphincter on the intestinal tube gradually increased and eventually became constant during closure, and the pressure value was always less than the intestinal blood supply pressure threshold. CONCLUSIONS: In this paper, we designed an artificial anal sphincter based on biomechanical compatibility and the corresponding in vitro simulation experimental program and preliminarily verified the effectiveness, safety, and constant force characteristics of the artificial anal sphincter.

Efficacy of atypical antipsychotics in the treatment of fecal incontinence in children and adolescents: a randomized clinical trial.

OBJECTIVES: Functional retentive overflow incontinence (retentive FI) is the most common cause of fecal soiling in children. Based on the clinical experiences, the treatment of retentive FI in patients with comorbid psychiatric disorders was accelerated when Risperidone was used as treatment for their psychiatric comorbidities; therefore, this study was conducted to evaluate the effect of risperidone in the treatment of retentive FI in children and adolescents. METHODS: In this double-blind, randomized, placebo-controlled trial, 140 patients aged 4-16 years eligible for the study were randomized into two groups, receiving either 0.25-0.5 mg of Risperidone syrup (n = 70) or maltodextrin syrup (placebo group, n = 70) every 12 h daily for 12 weeks. Sociodemographic data, including age, sex, weight, height, BMI, BMI z-score, and socioeconomic status, was recorded, and the number of nocturnal FI, diurnal FI, and painful defecations was measured. RESULTS: 136 participants (69 on Risperidone and 67 on placebo) were included in the study. Mean age of participants in the intervention and placebo groups were 7.2 ± 2.4 years and 8.0 ± 3.1 years, respectively. The mean number of nocturnal FI (Ptrend=0.39) and diurnal FI (Ptrend=0.48) in patients without psychiatric comorbidities, and the number of painful defecations for participants with and without psychiatric comorbidities (P = 0.49, P = 0.47, respectively) were not significantly different between the groups, but a significant effect was observed in diurnal FI after Risperidone treatment in patients with psychiatric comorbidities (P < 0.001). CONCLUSION: Risperidone, when used along with other non-pharmacological interventions, may be helpful in treating FI in pediatric patients with psychiatric comorbidities.
