Prevalence of combined fecal and urinary incontinence: a community-based study

Psychometric properties and feasibility of three scales assessing the level of knowledge and awareness about pelvic floor health

OBJECTIVE

Despite high prevalence and burden of pelvic floor dysfunctions (PFD), there is a limited number of scales assessing knowledge of pelvic floor health (PFH), and no studies comparing their psychometric or feasibility properties. The study aimed both to investigate the psychometric properties and feasibility of Incontinence Quiz (IQ), Prolapse and Incontinence Knowledge Questionnaire (PIKQ) and Pelvic Floor Health Knowledge Questionnaire (PFHKQ), and to compare level of PFH knowledge in women with and without PFD.

STUDY DESIGN

In this prospective cross-sectional study, a total of 150 women were included. After recording physical-sociodemographic characteristics, obstetric histories and menstrual status, Pelvic Floor Distress Inventory-20 and Female Sexual Function Index were administered to classify them into study groups as women with and without PFD. Their PFH knowledge was assessed using IQ, PIKQ and PFHKQ, which were filled twice with one week interval for the test-retest purpose. The scores, reliability, validity, ceiling-floor effects and feasibility of the knowledge scales were compared with each other, and between the study groups.

RESULTS

IQ, PIKQ, and PFHKQ scores of women with and without PFD were similar. Based on response patterns to items, PFHKQ had the highest internal consistency followed by PIKQ and IQ. The PIKQ was the most stable scale across the total sample and in the PFD group. The PFHKQ had the highest ICC value in women without PFD. There was a strong correlation between the total scores of knowledge scales in both groups. Scores of knowledge and symptom scales were not significantly correlated. IQ was completed in the shortest time, and was easier to complete than PFHKQ. Only the diagnosis/treatment subscale of PFHKQ had a ceiling effect.

CONCLUSION

It was concluded that PFH knowledge of women with and without PFD were at a low-moderate level and similar to each other; IQ, PIKQ and PFHKQ were reliable, valid and feasible scales, which can be used in measuring knowledge level about PFH.

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 human colon: Evidence for degenerative changes during aging and the physiological consequences

BACKGROUND

The incidence of constipation increases among the elderly (>65 years), while abdominal pain decreases. Causes include changes in lifestyle (e.g., diet and reduced exercise), disease and medications affecting gastrointestinal functions. Degenerative changes may also occur within the colo-rectum. However, most evidence is from rodents, animals with relatively high rates of metabolism and accelerated aging, with considerable variation in time course. In humans, cellular and non-cellular changes in the aging intestine are poorly investigated.

PURPOSE

To examine all available studies which reported the effects of aging on cellular and tissue functions of human isolated colon, noting the region studied, sex and age of tissue donors and study size. The focus on human colon reflects the ability to access full-thickness tissue over a wide age range, compared with other gastrointestinal regions. Details are important because of natural human variability. We found age-related changes within the muscle, in the enteric and nociceptor innervation, and in the submucosa. Some involve all regions of colon, but the ascending colon appears more vulnerable. Changes can be cell- and sublayer-dependent. Mechanisms are unclear but may include development of "senescent-like" and associated inflammaging, perhaps associated with increased mucosal permeability to harmful luminal contents. In summary, reduced nociceptor innervation can explain diminished abdominal pain among the elderly. Degenerative changes within the colon wall may have little impact on symptoms and colonic functions, because of high "functional reserve," but are likely to facilitate the development of constipation during age-related challenges (e.g., lifestyle, disease, and medications), now operating against a reduced functional reserve.

Global Prevalence of Fecal Incontinence in Community-Dwelling Adults: A Systematic Review and Meta-analysis

BACKGROUND & AIMS

Fecal incontinence (FI) can considerably impair quality of life. Through a systematic review and meta-analysis, we sought to determine the global prevalence and geographic distribution of FI and to characterize its relationship with sex and age.

METHODS

We searched PubMed, Web of Science, and Cochrane Library databases to identify population-based surveys of the prevalence of FI.

RESULTS

Of the 5175 articles identified, the final analysis included 80 studies; the median response rate was 66% (interquartile range [IQR], 54%-74%). Among 548,316 individuals, the pooled global prevalence of FI was 8.0% (95% confidence interval [CI], 6.8%-9.2%); by Rome criteria, it was 5.4% (95% CI, 3.1%-7.7%). FI prevalence was greater for persons aged 60 years and older (9.3%; 95% CI, 6.6%-12.0%) compared with younger persons (4.9%; 95% CI, 2.9%-6.9%) (odds ratio [OR], 1.75; 95% CI, 1.39-2.20), and it was more prevalent among women (9.1%; 95% CI, 7.6%-10.6%) than men (7.4%; 95% CI, 6.0%-8.8%]) (OR, 1.17; 95% CI, 1.06-1.28). The prevalence was highest in Australia and Oceania, followed by North America, Asia, and Europe, but prevalence could not be estimated in Africa and the Middle East. The risk of bias was low, moderate, and high for 19 (24%), 46 (57%), and 15 (19%) studies, respectively. Exclusion of studies with high risk of bias did not affect the prevalence of FI or heterogeneity. In the meta-regression, the high study heterogeneity (I2 = 99.61%) was partly explained by age.

CONCLUSIONS

Approximately 1 in 12 adults worldwide have FI. The prevalence is greater among women and older people.

Prevalence of Double Incontinence and Lower Urinary Tract Symptoms in Patients with Fecal Incontinence: A Single-center Observational Study

Objectives

Double incontinence (DI), which is the co-occurrence of fecal incontinence (FI) and urinary incontinence (UI), increases with age and has a greater negative impact on the quality of life (QOL) than either incontinence alone. We aimed to assess lower urinary tract symptoms (LUTS) in patients with FI to elucidate the prevalence and characteristics of DI.

Methods

This study enrolled consecutive patients who visited our hospital with FI symptoms. FI was evaluated using the Cleveland Clinic Florida Fecal Incontinence Score (CCFIS). LUTS were assessed using the International Prostate Symptom Score (IPSS), QOL score (IPSS-QOL) and Overactive Bladder Symptom Score (OABSS).

Results

This study evaluated 140 patients (96 women [mean age: 70.7 years] and 44 men [mean age: 74.4 years]). The mean IPSS was significantly higher in men than in women (12.0 vs. 7.5, p = 0.003). A positive correlation was found between IPSS and CCFIS in women (r = 0.256, p = 0.012) but not in men. For both sexes, the older group (aged ≥70 years) had higher OABSS scores and more urge UI instances than the younger group (aged ≤69 years). Of the 140 patients with FI, 78 (55.7%) had DI, and DI was more common in women than in men (63.5% vs. 38.6%, p = 0.006).

Conclusions

The characteristics of LUTS and UI in patients with FI were comparable to those in the general population for both sexes; however, the prevalence of DI was much higher among patients with FI than that in the general population.

Vitamin D levels and the risk of overactive bladder: a systematic review and meta-analysis

CONTEXT

Overactive bladder is treated mainly with behavioral and drug therapy, and symptoms of urinary frequency and incontinence are challenging to eliminate. There is thus a continuous unmet need for new drugs with a substitution effect mechanism.

OBJECTIVE

It not known whether vitamin D deficiency can lead to overactive bladder or urinary incontinence or whether vitamin D supplementation alleviates bladder symptoms. This comprehensive systematic review with meta-analysis was conducted to determine whether overactive bladder is associated with vitamin D deficiency.

DATA SOURCES

The PubMed and Cochrane Library databases were searched systematically up to July 3, 2022.

DATA EXTRACTION

Initially, 706 articles were identified in the literature search, of which 13 were included in the systematic review: 4 randomized controlled trials, 3 cohort studies, 3 cross-sectional studies, and 3 case-control studies.

DATA ANALYSIS

An increased risk of overactive bladder and urinary incontinence was observed with vitamin D deficiency (odds ratio [OR] = 4.46; 95%CI, 1.03-19.33; P = 0.046 and OR = 1.30; 95%CI, 1.01-1.66; P = 0.036, respectively). Vitamin D levels were relatively low in patients with overactive bladder or urinary incontinence (SMD = -0.33; 95%CI, -0.61 to -0.06, P = 0.019). On the basis of existing data, the risk of urinary incontinence was reduced by 66% after vitamin D supplementation (OR = 0.34; 95%CI, 0.18-0.66; P = 0.001). Egger test was conducted to assess publication bias, and the results were tested for robustness using a sensitivity analysis.

CONCLUSIONS

Vitamin D deficiency increases the risk of overactive bladder and urinary incontinence, and vitamin D supplementation reduces the risk of urinary incontinence. The development of new strategies to prevent or alleviate bladder symptoms is crucial. Vitamin D supplementation may be gaining recognition as an effective strategy for prevention or alleviation of bladder symptoms such as overactive bladder and incontinence.

Characteristics of Fecal Incontinence in Male Patients in Japan

OBJECTIVES

Although community studies have shown no difference between the sexes in the prevalence of fecal incontinence (FI), few direct comparisons of disease characteristics between male and female patients have been reported. The aim of this study was to determine whether characteristics of FI differ between male and female patients in Japan.

METHODS

Included in the study were 408 (149 men, 259 women) patients with FI who visited the Matsushima Hospital Coloproctology Center between October 2016 and September 2017. We retrospectively evaluated data on age, number of bowel movements, Bristol stool form scale, number of FI, incontinence scores, anorectal manometry, comorbidities, and history of anal surgery.

RESULTS

Maximum resting pressure and maximum squeeze pressure were found to be within normal range in significantly more male than female patients (34.9% vs. 12.4%, respectively; p < 0.0001). Irritable bowel syndrome (IBS, 20.1% vs. 9.3%; p = 0.003) and a history of anal surgery (29.5% vs. 17.5%; p = 0.02) were more prevalent among male patients than among female patients. Use of mepenzolate as treatment was significantly more common among male patients than among female patients (16.8% vs. 6.6%, respectively; p = 0.005). Responses to the various treatments were good, regardless of sex.

CONCLUSIONS

FI appears to be more commonly accompanied by normal anal sphincter pressures in male patients than in female patients, and IBS and previous anal surgery appear to be more common among male patients than among female patients. FI appears to be controllable in most patients, regardless of sex.

Association between Fecal Incontinence and Lower Urinary Tract Symptoms and their Impact on the Quality of Life of Patients with Prostate Cancer

Objective To evaluate the association of fecal incontinence (FI) and lower urinary tract symptoms (LUTS) in patients diagnosed with initial prostate cancer (PC) and after any therapeutic approach (surgery and radiotherapy).

Methods Cross-sectional study using the Cleveland Clinic Incontinence Score (CCIS), the Fecal Incontinence Quality of Life (FIQL) questionnaire, and the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB).

Results A total of 84 patients with PC were included: 40 of them had not started treatment, 31 were submitted to radical prostatectomy (RP), and 13 were submitted to radiotherapy (RT). Those submitted to RT presented higher scores on the ICIQ-OAB (p = 0.01). When comparing the whole sample reagarding the patients with and without FI, we observed that the incontinents presented a higher frequency of urinary incontinence (UI) (p < 0.001). Moreover, when comparing patients with/without FI within their treatment groups regarding the presence of UI and FIQL scores, we identified that patients undergoing RP presented an association between UI and FI (p < 0.001) and a greater impact of FI on the FIQL (p < 0.001).

Conclusion Patients submitted to RT present more intense LUTS. Moreover, patients with FI present a higher association with UI, and this association is more marked in those with FI submitted to RP.

Prevalence and Risk Factors of Anal and Fecal Incontinence in Japanese Medical Personnel

Objectives

This study aimed to elucidate the actual state of anal incontinence (AI), fecal incontinence (FI), and the associated factors in Japanese medical personnel.

Methods

A questionnaire was completed by Japanese medical personnel after listening to lectures on AI. AI was defined as involuntary loss of feces or flatus.

Results

A total of 463 persons (mean age, 35.6 years; range, 20-91; male/female/no answer, 132/324/7) participated in the questionnaire. AI occurred in 34.4% of 450 participants (flatus/liquid stool/solid stool: 30.4%/3.6%/0.4%). AI was significantly more prevalent in females (male/female: 15.5%/42.7%, p < 0.001). AI and FI occurred significantly more prevalent in participants aged ≧40 years (p < 0.024). AI was significantly associated with childbirth, frequency of childbirth (more than three times), vaginal delivery, urinary incontinence, the style of urination/defecation, and a history of gynecologic surgery and systemic diseases (p < 0.05). Female gender and age as well as urinary incontinence and inability to defecate separately in female and previous colorectal disease and/or surgery in male were risk factors of AI by multivariate analysis (p < 0.05). FI was correlated with urinary incontinence.

Conclusions

AI and FI occurred in 34.4% and 4.0% of Japanese medical personnel, respectively. Gas incontinence was common in every age group. AI was associated with female gender, higher age group, urinary incontinence, the style of urination and defecation in female, and previous colorectal disease and/or surgery in male. FI was associated with urinary incontinence.

An association between incontinence and antipsychotic drugs: A systematic review

To date, due to the increasing prevalence of psychiatric diseases, the use of antipsychotic drugs has expanded. One of the proven side effects of these drugs is incontinence. Treatment of this complication improves the quality of life in these patients, increases self-confidence, and betters cope with their psychiatric illness. The exact mechanism of this side effect is not fully understood, but various methods have been used experimentally to deal with it. Strategies such as behavior therapy, discontinuation or change of drugs, reducing the dose of drugs, and adding drugs with less incontinence have been used. Each of these methods and studies has different results that need to be summarized to make optimal use of them. Since most of these reports are case reports with a low statistical population, our study has systematically reviewed these studies to find a comprehensive model to deal with this complication.

Perianal ultrasound (PAUS): visualization of sphincter muscles and comparison with digital-rectal examination (DRE) in females

Background

The aim of this study was to determine the reproducibility and tolerance of perianal ultrasound (PAUS) and detect differences in sphincter muscles between various measuring positions and different maneuvers. PAUS was compared to digital-rectal examination (DRE) to see if sphincter contraction is visible and gradable in ultrasound volumes.

Methods

Fifty women underwent a medical history, DRU and PAUS by two uro-gynecologists in a prospective trial. PAUS volumes were measured via different parameters in different maneuvers. Examiners’ DRE impressions of sphincter tone were scaled with the DRESS-score. All patients completed a questionnaire.

Results

Thirty-five patients with complete PAUS and DRE were included in the study. Fifteen patients were excluded due to poor ultrasound volume quality or sphincter defects. Comparison of sphincter muscle thickness at different positions in PAUS showed significant differences between 6 and 12 o’clock positions (12 > 6 o’clock) and diameters (horizontal > vertical). No difference was found between the examiners. In comparison of rest and contraction only the vertical diameter changed. There was a negative but not significant correlation between PAUS measurements and DRESS-scores. Twenty-six patients completed the questionnaire that revealed women preferred PAUS over DRE.

Conclusion

PAUS is a reproducible and good tool to visualize the anal canal. It is comfortable for patients and easily handled by examiners. Sphincter muscle contraction is iso-volumetric. Vertical diameter changes during contraction leading the anal canal change its shape to oval due to external influence. PAUS is the ideal additional tool to visualize relevant structures that are palpable on DRE.

Artificial intelligence models derived from 2D transperineal ultrasound images in the clinical diagnosis of stress urinary incontinence

INTRODUCTION AND HYPOTHESIS

The aim of the study was to develop artificial intelligence (AI) algorithms using 2D transperineal ultrasound (TPUS) static images to simplify the clinical process of diagnosing stress urinary incontinence (SUI) in practice.

METHODS

The study involved 400 patients in total, including 265 SUI patients and 135 non-SUI patients who underwent a routine clinical evaluation process by urologists and TPUS. They were classified into different groups based on the International Consultation on Incontinence Questionnaire (ICIQ) to assess the impact of inconvenience on patients' lives. Four AI models were developed by 2D TPUS images: Model A (a single-mode model based on Valsalva maneuver images to classify G-0, G-1, and G-2); Model B (a dual-mode model based on Valsalva maneuver and resting state images to classify G-0, G-1, and G-2); Model C (a single-mode model based on Valsalva maneuver images to classify G-2 and G-01); Model D (a dual-mode model based on Valsalva maneuver and resting state images to classify G-2 and G-01). The performance of the four models was evaluated by confusion matrices and the area under the receiver-operating characteristic curve (AUC).

RESULTS

The dual-mode model based on the Valsalva maneuver and resting-state images (Model D) had a higher accuracy of 86.3% and an AUC of 0.922, which was significantly higher than the AUCs of the other three models: 0.771, 0.862, and 0.827.

CONCLUSIONS

The AI algorithm using 2D TPUS static images of the Valsalva maneuver and resting state may be a promising tool in the diagnosis of SUI patients in to relieve clinical processes in practice given its ease of use in clinical applications.

Japanese Practice Guidelines for Fecal Incontinence Part 1-Definition, Epidemiology, Etiology, Pathophysiology and Causes, Risk Factors, Clinical Evaluations, and Symptomatic Scores and QoL Questionnaire for Clinical Evaluations-English Version

Fecal incontinence (FI) is defined as involuntary or uncontrollable loss of feces. Gas incontinence is defined as involuntary or uncontrollable loss of flatus, while anal incontinence is defined as the involuntary loss of feces or flatus. The prevalence of FI in people over 65 in Japan is 8.7% in the male population and 6.6% among females. The etiology of FI is usually not limited to one specific cause, with risk factors for FI including physiological factors, such as age and gender; comorbidities, such as diabetes and irritable bowel syndrome; and obstetric factors, such as multiple deliveries, home delivery, first vaginal delivery, and forceps delivery. In the initial clinical evaluation of FI, the factors responsible for individual symptoms are gathered from the history and examination of the anorectal region. The evaluation is the basis of all medical treatments for FI, including initial treatment, and also serves as a baseline for deciding the need for a specialized defecation function test and selecting treatment in stages. Following the general physical examination, together with history taking, inspection (including anoscope), and palpation (including digital anorectal and vaginal examination) of the anorectal area, clinicians can focus on the causes of FI. For the clinical evaluation of FI, it is useful to use Patient-Reported Outcome Measures (PROMs), such as scores and questionnaires, to evaluate the symptomatic severity of FI and its influence over quality of life (QoL).

Initial experience with SphinKeeper™ intersphincteric implants for faecal incontinence in the UK: a two-centre retrospective clinical audit

AIM

The SphinKeeper™ artificial bowel sphincter implant is a relatively new surgical technique for the treatment of refractory faecal incontinence. This study presents the first experience in two UK tertiary centres.

METHOD

This is a retrospective audit of prospectively collected clinical data in relation to technique, safety, feasibility and short-term effectiveness from patients undergoing surgery from January 2016 to April 2019. Baseline data, intra-operative and postoperative complications, symptoms [using St Mark's incontinence score (SMIS)] and radiological outcomes were analysed.

RESULTS

Twenty-seven patients [18 women, median age 57 years (range 27-87)] underwent SphinKeeper. In 30% of the patients, the firing device jammed and not all prostheses were delivered. There were no intra-operative complications and all patients were discharged the same or the following day. SMIS significantly improved from baseline [median -6 points (range -12 to +3); P < 0.00016] with 14/27 (51.9%) patients achieving a 50% reduction in the SMIS score. On postoperative imaging, a median of seven prostheses (range 0-10) were identified with a median of five (range 0-10) optimally placed. There was no relationship between number of well-sited prostheses on postoperative imaging and categorical success based on 50% reduction in SMIS (χ² test, P = 0.79).

CONCLUSION

SphinKeeper appears to be a safe procedure for faecal incontinence. Overall, about 50% patients achieved a meaningful improvement in symptoms. However, clinical benefit was unrelated to the rate of misplaced/migrated implants. This has implications for confidence in proof of mechanism and also the need for technical refinement.

Toileting difficulties in older people with and without dementia receiving formal in-home care-A longitudinal study

AIM

To estimate the prevalence of toileting difficulties over time among older people (≥70 years) with and without dementia receiving formal in-home care at baseline and to explore whether dementia at baseline was associated with toileting difficulties at the last assessment when adjusting for relevant covariates. We hypothesize that those with dementia have a higher prevalence and that baseline dementia is associated with toileting difficulties at last follow-up.

DESIGN

A longitudinal observational study with three assessments over 36 months. Older people (≥70 years) from 19 Norwegian municipalities with in-home care needs were included. The participants and their next of kin were interviewed.

METHOD

In total, 1,001 (68% women) persons with a mean (SD) age 83.4 (5.7) years participated at baseline. Toileting difficulties were assessed using Lawton and Brody's Physical Self-Maintenance Scale and Individual Nursing and Care Statistics. Information on physical comorbidity, number of prescribed drugs, cognitive function and formal care given was included. Dementia was diagnosed based on all information gathered.

RESULTS

At all time points, toileting difficulties were more prevalent in people with than without dementia. In adjusted analyses, dementia at baseline was associated with toileting difficulties at the last assessment. Nursing home admission was associated with increased odds for toileting difficulties.

Sensitive Skin in the Genital Area

When evaluating sensitive skin, it is common to focus on the face. However, it is becoming increasingly clear that individuals can have different perceptions about the degree of skin sensitivity at distinct anatomic sites. Structural variations in the skin of different body sites can contribute to differences in barrier function, which may contribute to differences in skin sensitivity. Potential triggering factors for skin sensitivity would be expected to vary by body site. For example, the face is exposed to all ambient environmental conditions in the course of daily life, and to several products (e.g., cosmetics for women) and practices (e.g., shaving for men) that may lead to adverse sensations associated with sensitive skin. In contrast, the skin of the genital area is protected from ambient environmental conditions. However, the genital area can be exposed to conditions of higher temperature, different habits and practices and moisture due to the semi-occlusive environment. For some individuals, additional challenges such as incontinence can provide triggering factors for skin sensitivity that effect only the genital area. This article reviews data on the perception of sensitive skin of the genital area, differences based on gender, age, racial differences, and the effects of incontinence on skin sensitivity. The effects of menopause are also considered with regards to sensitive skin perceptions and to emerging differences in biomolecular and physical measures of the urogenital skin.

Risk Factors for Fecal Urgency Among Individuals With and Without Diarrhea, Based on Data From the National Health and Nutrition Examination Survey

BACKGROUND & AIMS

Fecal urgency is a common symptom among patients with gastrointestinal disorders, but can also occur in healthy individuals with normal bowel habits. There have been few studies of fecal urgency in the general population. We performed a cross-sectional analysis of data from the National Health and Nutrition Examination Survey (NHANES) to analyze the prevalence of and risk factors for this symptom.

METHODS

We analyzed data from 4676 persons who completed the Bowel Health Questionnaire from the NHANES, from 2009 through 2010. The NHANES sampled a nationally representative group of adults in the United States and provides information on demographics, medical comorbidities, and dietary habits of survey participants. The Bowel Health Questionnaire provided additional information about bowel symptoms such as urgency, incontinence, constipation, and diarrhea. We identified individuals with fecal urgency and calculated differences in fecal urgency among subgroups using chi-squared analysis. We used logistic regression to identify factors associated with urgency.

RESULTS

In our study population, the prevalence of fecal urgency was 3.3%; 29.5% of individuals with fecal urgency had diarrhea. The prevalence of fecal urgency was significantly higher in individuals who had diarrhea (14.8%) than in individuals without diarrhea (3.1%). Older age, female sex, poverty, urinary urge incontinence, diarrhea, and increased stool frequency were all associated with fecal urgency on multivariable analysis. Decreased fiber intake and increased carbohydrate intake were associated with urgency among individuals with diarrhea.

CONCLUSIONS

In an analysis of data from 4676 individuals who completed a Bowel Health Questionnaire from the NHANES, we found a significantly higher proportion of individuals with diarrhea to have fecal urgency. However, most individuals with fecal urgency do not have diarrhea. Factors associated with fecal urgency vary among individuals with and without diarrhea.

Prevalence of and Factors Associated With Fecal Incontinence: Results From a Population-Based Survey

BACKGROUND & AIMS

Fecal incontinence (FI) is characterized by uncontrolled passage of solid or liquid stool. We aimed to determine the prevalence and severity of FI in a large sample of US residents.

METHODS

We recruited a representative sample of patients in October 2015 to complete the National Gastrointestinal (GI) Survey; a mobile app called MyGiHealth was used to systematically collect data on GI symptoms. FI was defined as accidental leakage of solid or liquid stool. Severity of FI was determined by responses to the National Institutes of Health FI Patient Reported Outcomes Measurement Information System questionnaire. Multivariable regression models were used to identify factors associated with FI prevalence and severity.

RESULTS

Among 71,812 individuals who completed the National GI Survey, 14.4% reported FI in the past; of these, 33.3% had FI within the past 7 days. Older age, male sex, and Hispanic ethnicity increased the likelihood of having FI within the past week. Individuals with Crohn's disease, ulcerative colitis, celiac disease, irritable bowel syndrome, or diabetes were more likely to report FI. Non-Hispanic black and Hispanic individuals and individuals with Crohn's disease, celiac disease, diabetes, human immunodeficiency virus/acquired immunodeficiency syndrome, or chronic idiopathic constipation had more severe symptoms of FI than individuals without these features.

CONCLUSIONS

In a large population-based survey, 1 in 7 people reported previous FI. FI is age-related and more prevalent among individuals with inflammatory bowel disease, celiac disease, irritable bowel syndrome, or diabetes than people without these disorders. Proactive screening for FI among these groups is warranted.

Prevalence of anal incontinence in a working population within a healthcare environment

OBJECTIVES

Anal incontinence is a devastating affliction with several considerations that make it difficult to define in terms of epidemiology with good precision. The aim of the present work is to study the prevalence of an important disorder such as anal incontinence in a healthy working population within a sanitary environment.

MATERIAL AND METHODS

A cluster of easy understanding and filling inquiry forms are distributed to 910 apparently healthy individuals at our hospital. This questionnaires include filiation data, passed medical history, presence or not of Incontinence and other symptoms such as urgency. The Cleveland Clinic Incontinence Score is also registered.

RESULTS

Anal incontinence is present in a 21.2% of subjects when considered in any of it forms (flatus, liquid or solid faeces). A Clevleand Clinic Incontinence Score higher than 6 was obtained in a 7.3% of the sample and higher than 10 in 1.2%. No gender predominance has been identified. A slightly higher severity is recognised with increasing age. Obstetric and anal surgical background are the only related factors identified in the studied sample.

CONCLUSIONS

Faecal incontinence is a high prevalent affliction, even among apparently healthy population. Considering the aetiologic factors that have been established, prevention during obstetric and anal surgical procedures is absolutely mandatory.

Female double incontinence: prevalence, incidence, and risk factors from the SABE (Health, Wellbeing and Aging) study

INTRODUCTION AND HYPOTHESIS

Double Incontinence (DI) is incontinence of urine and stool and is an extreme manifestation of pelvic floor dysfunction. The objective of this study was to estimate the prevalence and incidence of DI and the risk factors in elderly women in São Paulo, Brazil.

METHODS

This was a prospective study in women aged 65 years or older evaluated in 2006 and re-evaluated in 2010. The sample was selected by two-phase stratified sampling with replacement and probability proportional to size. The likelihood ratio test was performed and Cox regression curves were generated to evaluate the equality of survival. Poisson's regression was used to evaluate risk factors.

RESULTS

This is the first study on the incidence of DI in elderly women. A total of 864 elderly women were interviewed in 2006. The prevalence rate of DI was 4.9%. The incidence rate of DI in the period between 2006 and 2010 was 13.8/1,000 person-years. Associated factors were the presence of chronic obstructive pulmonary disease, hypertension, difficulty with basic activities of daily living (BADL) and instrumental activities of daily living (IADL), polypharmacy and falls in the last year. Poisson's regression analysis showed that falls in the last year and difficulty with at least three IADL were risk factors for DI.

CONCLUSIONS

The incidence of DI seems to be high in this population. Falls in the last year and difficulty with at least three IADL were identified as risk factors. Preventive measures must be implemented with public health policies to prevent increases in DI.

Systematic review of the prevalence of faecal incontinence

BACKGROUND

Faecal incontinence (FI) is widely recognized as a significant problem in the community. Conjecture exists around the proportion of the population affected. This systematic review evaluated studies reporting the community prevalence of FI in terms of methodology, design and definitions.

METHODS

MEDLINE, Embase, CINAHL, the Cochrane Collaboration and National Guideline databases were searched for studies investigating the prevalence of FI in community-based adults published from January 1966 to February 2015. Study data, including methodology, sample size, response rate, definition of FI and prevalence rates, were extracted on to a pro forma and appraised critically. Where possible, FI prevalence estimates were pooled.

RESULTS

Thirty studies were analysed from 4840 screened articles. FI prevalence estimates varied from 1·4 to 19·5 per cent. This variation was explained by differences in data collection method and two factors within definitions of FI: type of stool and frequency of FI episodes. When these factors were accounted for, the FI prevalence at a threshold of at least once per month for liquid or solid stool was 8·3-8·4 per cent for face-to-face or telephone interviews, and 11·2-12·4 per cent for postal surveys. The pooled prevalence rate from studies for functional FI (defined by ROME II criteria) was 5·9 (95 per cent c.i. 5·6 to 6·3) per cent.

CONCLUSION

When comparable methodologies and definitions are used, studies produce remarkably similar prevalence rates in different community populations. FI remains an unspoken symptom, with lower rates reported in personal interviews compared with anonymous postal questionnaires.

Dynamic Article: Percutaneous Nerve Evaluation Versus Staged Sacral Nerve Stimulation for Fecal Incontinence

BACKGROUND

Sacral neuromodulation using a 2-staged approach is an established therapy for fecal incontinence. Office-based percutaneous nerve evaluation is a less-invasive alternative to the stage 1 procedure but is seldom used in the evaluation of patients with fecal incontinence.

OBJECTIVE

The aim of this study was to determine the clinical success of percutaneous nerve evaluation versus a staged approach.

DESIGN

This was a retrospective review of a prospectively maintained, single-institution database of patients treated with sacral neuromodulation for fecal incontinence.

SETTINGS

This study was conducted at a single academic medical center.

PATIENTS

Eighty-six consecutive patients were treated with sacral neuromodulation for fecal incontinence.

INTERVENTIONS

Percutaneous nerve evaluation was compared with a staged approach.

MAIN OUTCOME MEASURES

The primary outcome measured was the proportion of patients progressing to complete implantation based on >50% improvement in Wexner score during the testing phase.

RESULTS

Percutaneous nerve evaluation was performed in 45 patients, whereas 41 underwent a staged approach. The mean baseline Wexner score did not differ between testing groups. Success was similar between the staged approach and percutaneous nerve evaluation (90.2% versus 82.2%; p = 0.36). The mean 3-month Wexner score was not significantly different between testing methods (4.4 versus 4.1; p = 0.74). However, infection was more likely to occur after the staged approach (10.5% versus 0.0%; p < 0.05).

LIMITATIONS

This study was limited by its retrospective nature and potential for selection bias.

CONCLUSIONS

Percutaneous nerve evaluation offers a viable alternative to a staged approach in the evaluation of patients for sacral neuromodulation in the setting of fecal incontinence. Not only are success rates similar, but percutaneous nerve evaluation also has the benefit of limiting patients to 1 operating room visit and has lower rates of infection as compared with the traditional staged approach for sacral neuromodulation.

Safety of combined abdominal sacral colpopexy and sigmoid resection with suture rectopexy: a retrospective cohort study

OBJECTIVES

This study aimed to determine if abdominal sacral colpopexy (ASC) using mesh can be safely combined with sigmoid resection and anastomosis.

METHODS

This is a single institution, retrospective chart review of patients who underwent combined ASC and suture rectopexy with sigmoid resection between January 1, 2007, and December 31, 2011. Charts were screened for outcome data and complications related to the placement of synthetic mesh at the time of bowel resection to include readmission and reoperation rates, infection, bowel obstruction, fistula, and mesh erosion. Outcome data for patients receiving combined procedures were compared to 2 separate cohorts of patients as follows: a group that underwent only ASC with polypropylene mesh and a group that underwent only sigmoid resection plus or minus suture rectopexy. The DINDO surgical classification system was used for each cohort to further analyze complications.

RESULTS

There were 133 patients in the ASC only group (ASC only), 34 in the combined ASC and sigmoid resection group (Combined), and 27 in the sigmoidectomy plus rectopexy group (Colorectal only). The Colorectal only cohort had a higher rate of postoperative ileus; ASC only 3.8%, Combined 5.9%, Colorectal 22.2% (P = 0.004). There were otherwise no differences in intraoperative and postoperative complications or in the DINDO classification scores.

CONCLUSIONS

Abdominal sacral colpopexy with placement of synthetic mesh at the time of sigmoid resection and anastomosis does not seem to increase the rate of intraoperative or postoperative complications.

Assessing the dermal compatibility of a new female incontinence product line

CONTEXT

We have developed a line of products designed to better meet the overall needs of women suffering from urinary incontinence. The products are more discrete and contain a unique odor neutralizing technology (ONT).

OBJECTIVE

This paper describes the overall skin compatibility program for this product line in which the new products were compared to negative controls and/or commercially marketed reference products with an established history of safe use.

MATERIALS AND METHODS

Test products consisted of several product forms (light pads/pantiliners, moderate pads, briefs and taped diapers) with ONT and having various degrees of protection. Studies were conducted using standard protocols for 4-day and 21-day cumulative irritation, the Human Repeat Insult Patch Test (HRIPT), and the Behind-the-Knee (BTK) test for mechanical and chemical irritation. In one 4-day irritation study and one HRIPT, test subjects consisted of individuals with self-assessed sensitive skin. In addition, one 4-day study was conducted using normal skin sites, and sites compromised by tape stripping. Nonirritant controls were physiologic saline and/or current, commercially marketed incontinence products. All responses were evaluated by visual scoring of erythema. In addition, in the BTK, transepidermal water loss (TEWL) and adverse sensory effects collected from panelists' daily diaries were also evaluated.

RESULTS AND DISCUSSION

Two 4-day cumulative irritation studies and one 21-day study demonstrated that a wide range of product forms (liners, light and moderate pads, briefs and adult diapers) produced skin reactions similar to the nonirritant controls. The 4-day study conducted using sensitive skin subjects showed good skin compatibility, and the test products were comparable to the nonirritant controls. In the 4-day study with both normal and compromised skin sites, test products produced mean erythema scores similar to the nonirritant controls. Three HRIPT separate studies confirm that the products do not induce contact sensitization, including one study conducted on individuals with self-assessed sensitive skin. In the BTK, test and control products produced similar irritation, as assessed by erythema, TEWL and sensory effects.

CONCLUSION

The results from the patch tests and mechanical irritation test demonstrate good skin compatibility of the new line of products with the unique ONT. In addition, the forms of the product (i.e. liner, pad or brief), were equally compatible with skin.

Fecal Incontinence: Community Prevalence and Associated Factors--A Systematic Review

BACKGROUND

Fecal incontinence is a chronic and debilitating condition with significant health burden. Despite its clinical relevance, the prevalence of fecal incontinence remains inconsistently described.

OBJECTIVE

This study aimed to systematically review the literature regarding the prevalence of and factors associated with fecal incontinence among community-dwelling adults.

DATA SOURCES

A search of the PubMed, Embase, and Cochrane databases was performed.

STUDY SELECTION

Studies that reported the prevalence of fecal incontinence and/or associated factors in a community-based (ie, unselected) adult population were included. Two independent assessors reviewed eligible articles.

MAIN OUTCOME MEASURES

Relevant data were extracted from each study and presented in descriptive form. The main outcome measures included the prevalence of fecal incontinence (adjusted and/or unadjusted), stratified for age and sex if reported; factors associated (and not associated) with fecal incontinence; and study quality, assessed using predefined criteria.

RESULTS

Of 3523 citations identified, 38 studies were included for review. The reported median prevalence of fecal incontinence was 7.7% (range, 2.0%-20.7%). Fecal incontinence equally affected both men (median, 8.1%; range, 2.3%-16.1%) and women (median, 8.9%; range, 2.0%-20.7%) and increased with age (15-34 years, 5.7%; >90 years, 15.9%). The study populations and diagnostic criteria used were heterogeneous, precluding any meaningful pooling of prevalence estimates. Study quality assessment revealed 6 high-quality studies, of which only 3 were performed in a representative sample. The median prevalence of fecal incontinence was higher in these studies at 11.2% (range, 8.3%-13.2%). The factors most commonly reported to be associated with fecal incontinence included increasing age, diarrhea, and urinary incontinence.

LIMITATIONS

Heterogeneity of studies precluded meaningful pooling or meta-analysis of data.

CONCLUSIONS

Fecal incontinence is a prevalent condition of equal sex distribution, affecting ≈1 in 8 community adults, and has identifiable associated factors. The paucity of high-quality prevalence studies emphasizes the need for future population-based studies that use standardized diagnostic criteria for fecal incontinence.

Increasing Discussion Rates of Incontinence in Primary Care: A Randomized Controlled Trial

BACKGROUND

A minority of women with urinary incontinence (UI) and even fewer with fecal incontinence (FI) report having discussed it with a health care provider in the past year. Thus our aim was to evaluate whether the use of an electronic pelvic floor assessment questionnaire (ePAQ-PF) improves communication about incontinence in primary care.

METHODS

Women 40 years and older who were scheduled for an annual wellness physical at an internal medicine clinic between August 2007 and August 2008 were randomized to complete the ePAQ-PF prior to (n = 145) or after (n = 139) their visit. Clinicians of women in the intervention group received the ePAQ-PF report prior to the visit. Outcome measures from clinic note abstraction included mention of UI (primary) and FI. Participant-reported outcome measures included discussion of UI and FI and initiator of discussion.

RESULTS

Discussions of UI was more common in the intervention group than the control group: (27% vs. 19%; odds ratio [OR], 1.6 95% confidence interval [95%CI] 0.9-2.8, particularly for women over 60 (33% vs. 12%; OR 3.8, 95%CI 1.2-11.8) and for women with UI (42% vs. 25%; OR 2.2, 95%CI 1.1-4.1). The intervention primarily led to an increase in clinician-initiated UI discussions which were more common in the intervention group (18% vs. 4%, OR 4.8, 95%CI 1.9-12.0) Participants in the intervention group more frequently reported discussion of FI (14% vs. 6%; OR 2.5, 95%CI 1.1-6.0) which was clinician initiated in over half the cases (9% vs. 3%; OR 3.5, 95%CI 1.1-11.0).

CONCLUSIONS

Use of the ePAQ-PF prior to clinic visits increases discussion of UI and FI, particularly clinician-initiated discussion. These findings suggest that such instruments may increase the detection and treatment of this often "silent" affliction.

Urinary, fecal, and dual incontinence in older U.S. Adults

OBJECTIVES

To estimate the prevalence of urinary (UI), fecal (FI), and dual incontinence (DI) and to identify shared factors associated with each type of incontinence in older U.S. women and men.

DESIGN

Population-based cross-sectional study.

SETTING

National Health and Nutrition Examination Survey (NHANES, 2005-2010).

PARTICIPANTS

Women and men aged 50 and older.

MEASUREMENTS

UI was defined as moderate to severe (≥3 on a validated UI severity index, range 0-12); FI was at least monthly loss of solid, liquid, or mucus stool; and DI was the presence of UI and FI.

RESULTS

Women were more likely than men to report UI only and DI but not FI only (UI only, women 19.8%, men 6.4%; FI only, women 8.2%, men 8.4%; DI women, 6.0%, men 1.9%). In both sexes, prevalence increased with age. In regression models adjusted for parity and hysterectomy, DI in women was associated with non-Hispanic white race (odds ratio (OR)=2.3, 95% confidence interval (CI)=1.5-3.4), depression (OR=4.7, 95% CI=2.0-11.1), comorbidities (OR=4.3, 95% CI=1.9-9.6 for ≥3 comorbidities vs none), hysterectomy (OR=1.8, 95% CI=1.2-2.7), and diarrhea (OR=2.8, 95% CI=1.5-5.0). In men, ADL impairment (OR=2.4, 95% CI=1.2-4.9) and poorer self-rated health (OR=2.8, 95% CI=1.5-5.30) were associated with DI.

CONCLUSION

UI, FI, and DI are common in older women and men. Factors associated with DI were distinct from those associated with UI and FI. There were also differences according to sex, with DI associated with depression and comorbid diseases in women and lack of functional ability and poorer self-rated health in men.

Clustering of pelvic floor disorders 20 years after one vaginal or one cesarean birth

INTRODUCTION AND HYPOTHESIS

The objective was to assess the prevalence and risk factors for co-occurring pelvic floor disorders (PFDs): urinary incontinence (UI), symptomatic pelvic organ prolapse (sPOP), and fecal incontinence (FI), 20 years after one vaginal (VD) or one cesarean (CS) delivery.

METHODS

We carried out a registry-based national cohort study of primiparae who delivered during the period 1985-1988 and had no further deliveries. Medical Birth Registry data were linked to data from postal questionnaires distributed 20 years post-partum (response rate 65.2%, n = 5,236). Main outcome measures were prevalence and risk factors for combined and isolated PFDs.

RESULTS

The prevalence of any PFD was 46.5; 31.7% had one symptom and 14.8% had two or more. Co-occurring symptoms doubled after VD (17.1%) compared with CS (8.4%) (adjOR 2.26; 95% CI 1.84-2.79). The strongest association was observed between VD and having all three symptoms (adjOR 5.20; 95% CI 2.73-9.91), followed by the combination of sPOP and UI (adjOR 3.38; 95% CI 2.24-5.10). The degree of frustration perceived by the women because of pelvic floor dysfunction increased with each additional co-occurring PFD (p < 0.001). The strongest risk factors for clustering of PFDs were: VD (OR 2.19; 95% CI 1.75-2.73), family history (OR 2.03; 95% CI 1.73-2.34), and ≥2 degree tear (OR 1.78; 95% CI 1.24-2.55). Vacuum extraction and episiotomy were not risk factors.

CONCLUSIONS

The prevalence of co-occurring PFDs was high and was doubled in women after VD compared with CS. Women with UI most likely had it as an isolated symptom, whereas FI and sPOP more often occurred in combination.

Prevalence of functional bowel disorders and faecal incontinence: an Australian primary care survey

AIM

Interest in functional bowel disorders (FBDs) and faecal incontinence (FI) has increased amongst coloproctologists. The study aimed to assess the prevalence of FBDs and FI (including its severity) among Australian primary healthcare seekers using objective criteria.

METHOD

A cross-sectional survey was conducted in a primary care setting in Sydney, Australia. A self-administered questionnaire was used to collect demographic information and diagnose FBDs (irritable bowel syndrome, constipation, functional bloating and functional diarrhoea) based on Rome III criteria. The severity of FI was determined using the Vaizey incontinence score. Associations with medical/surgical history and healthcare utilization were assessed.

RESULTS

Of 596 subjects approached, 396 (66.4%) agreed to participate. Overall, 33% had FBD and/or FI. Irritable bowel syndrome was present in 11.1% and these participants were more likely to report anxiety/depression (P < 0.01) and to have had a previous colonoscopy (P < 0.001) or cholecystectomy (P = 0.02). Functional constipation was present in 8.1%, and functional bloating and functional diarrhoea were diagnosed in 6.1%, and 1.5%, respectively. FI was present in 12.1% with the majority (52%) reporting moderate/severe incontinence (Vaizey score > 8). Participants with FI were more likely to have irritable bowel syndrome, urinary incontinence and previous anal surgery (P < 0.01).

CONCLUSION

FBDs and FI are prevalent conditions amongst primary healthcare seekers and the needs of those affected appear to be complex given their coexisting symptoms and conditions. Currently, the majority do not reach colorectal services, although increased awareness by primary care providers could lead to sufferers being referred for specialist management.

Proctocolectomy for colorectal cancer--is the ileal pouch anal anastomosis a safe alternative to permanent ileostomy?

PURPOSE

Ileal pouch anal anastomosis (IPAA) is the procedure of choice in patients requiring surgery for ulcerative colitis (UC) and familial adenomatous polyposis (FAP). There are few data on reconstruction with the IPAA in patients with colorectal cancer (CRC). This study assessed the outcomes of the IPAA compared to proctocolectomy and permanent ileostomy (PI) on these patients.

METHODS

Between 1983 and 2013, over 2800 patients with CRC have been treated at the Mount Sinai Hospital (MSH). Demographic, surgical, pathological, and outcome data for all patients have been maintained in a database-73 patients were treated for CRC with proctocolectomy: 39 patients with IPAA and 34 patients with PI. Clinical features, pathologic findings, and survival outcomes were compared between these groups.

RESULTS

Each group was similar with respect to gender, stage, and histologic grade. Patients undergoing IPAA were significantly younger. The diagnosis leading to proctocolectomy was more commonly UC or FAP in patients treated with IPAA (39/39 vs. 23/34, p = 0.001). Rectal cancer subgroups were similar in age, sex, TNM stage, T-stage, height of tumor, and histologic grade. There was no significant difference in overall or disease free survival between groups for colon or rectal primaries. Analysis using the Cochran-Armitage trend test suggests that utilization of IPAA has increased over time (p = 0.002).

CONCLUSIONS

The IPAA is a viable and safe option to select for patients who would otherwise require PI. Increased experience and improved outcomes following IPAA has led to its more liberal use in selected patients.

Anal incontinence: long-term alterations in the incidence and healthcare usage

OBJECTIVE

The aim of the study was to determine the alterations in the occurrence of incontinence and how subjects suffering from incontinence seek and receive healthcare services over a 10-year follow-up period.

METHODS

Postal questionnaires (Wexner Incontinence Score, Fecal Incontinence Quality of Life Scale, a questionnaire to investigate the management of fecal incontinence and the frequency of urinary incontinence) were sent to subjects who had reported anal incontinence in our population-based study in 2003. For each incontinent person (n = 155) from the 2003 series, we identified two control subjects (n = 310) who did not suffer from incontinence.

RESULTS

Of the initially incontinent, 47 (58%) had remained incontinent after a follow up of 10 years. Almost 80% of the incontinent subjects in 2012 were female. Of the 152 initially continent, 12 (7.9%) had developed symptoms, all of whom were females. Urinary incontinence was present in approximately 60% of incontinent subjects. The majority (57.8%) of the subjects still incontinent in 2012 felt that they needed help for the complaint, but only 30.9% had received any, and only 7.4% received any benefit. The most common treatment was medication. The subjective incontinence impaired the quality of life.

CONCLUSION

Incontinence is a chronic long-lasting disorder. The current management of anal incontinence is not satisfactory. The primary healthcare system should be more aware of the nature of this condition to find and offer treatment for the patients.

Prevalence, trends, and risk factors for fecal incontinence in United States adults, 2005-2010

BACKGROUND & AIMS

We investigated the prevalence of and trends and risk factors for fecal incontinence (FI) in the United States among non-institutionalized adults from 2005 to 2010.

METHODS

We analyzed data from 14,759 participants in the U.S. National Health and Nutrition Examination Survey (49% women, 20 years or older) from 2005 to 2010 (the FI Severity Index was added in 2005-2006). FI was defined as accidental leakage of solid or liquid stool or mucus at least once in preceding month. Sampling weights were used to obtain estimates for the national population. Logistic regression was used to identify risk factors for FI.

RESULTS

The prevalence of FI among non-institutionalized U.S. adults was 8.39% (95% confidence interval, 7.76-9.05). It was stable throughout the study period: 8.26% in 2005-2006, 8.48% in 2007-2008, and 8.41% in 2009-2010. FI resulted in release of liquid stool in most cases (6.16%). Prevalence increased with age from 2.91% among 20- to 29-year-old participants to 16.16% (14.15%-18.39%) among participants 70 years and older. Independent risk factors for FI included older age, diabetes mellitus, urinary incontinence, frequent and loose stools, and multiple chronic illnesses. FI was more common among women only when they had urinary incontinence.

CONCLUSIONS

FI is a common problem among non-institutionalized U.S. adults. Its prevalence remained stable from 2005-2010. Diabetes mellitus and chronic diarrhea are modifiable risk factors. Future studies on risk factors for FI should assess for presence of urinary incontinence.

The epidemiology of anal incontinence and symptom severity scoring

For many patients, anal incontinence (AI) is a devastating condition that can lead to social isolation and loss of independence, contributing to a substantial economic health burden, not only for the individual but also for the allocation of healthcare resources. Its prevalence is underestimated because of poor patient reporting, with many unrecorded but symptomatic cases residing in nursing homes. Endosonography has improved our understanding of the incidence of post-obstetric sphincter tears that are potentially suitable for repair and those cases resulting from anorectal surgery, most notably after fistula and hemorrhoid operations. The clinical scoring systems assessing the severity of AI are discussed in this review, along with their limitations. Improvements in the standardization of these scales will advance our understanding of treatment response in an era where the therapeutic options have multiplied and will permit a better comparison between specific therapies.

Risk factors for urinary, fecal, or dual incontinence in the Nurses' Health Study

OBJECTIVE

To estimate the prevalence of urinary incontinence, fecal incontinence, and dual incontinence in a large cohort of older women and compare risk factors across the three conditions.

METHODS

These cross-sectional analyses used data from the Nurses' Health Study. The 2008 questionnaire, mailed to 96,480 surviving participants aged 62-87 years, included two separate items on the prevalence of urinary and fecal incontinence. A response of leakage at least once per month defined incontinence for both urine and stool. Dual incontinence was defined by responses at this frequency for both conditions. Using a polytomous logistic regression model, we assessed each risk factor for prevalence of urinary, fecal, and dual incontinence.

RESULTS

The survey was completed by 64,396 women. Thirty-eight percent had urinary incontinence alone, 4% had fecal incontinence alone, and 7% had dual incontinence. Age older than 80 years compared with age younger than 70 years was associated most strongly with dual incontinence (odds ratio [OR] 2.49, 95% confidence interval [CI] 2.28-2.73) followed by depression (OR 2.28, 95% CI 2.13-2.43), neurologic disease (OR 1.84, 95% CI 1.65-2.07), functional limitations (OR 1.86, 95% CI 1.71-2.02), multiparity (OR 1.66, 95% CI 1.41-1.94), and heavier fetal birth weight (OR 1.24, 95% CI 1.10-1.41). Obesity was associated only with urinary incontinence (OR 1.99, 95% CI 1.90-2.08) and type 2 diabetes mellitus was a stronger risk factor for fecal than urinary incontinence (OR 1.43, 95% CI 1.28-1.59). Black race was associated with a reduced risk of all types of incontinence, especially dual incontinence (OR 0.30, 95% CI 0.21-0.44).

CONCLUSION

In this large cohort, dual incontinence was primarily associated with advanced age, decompensating medical conditions, depression, and multiparity.

LEVEL OF EVIDENCE

Racial differences in fecal incontinence in community-dwelling women from the EPI study

OBJECTIVES

Despite its prevalence and associated distress, fecal incontinence (FI) is not well understood. There are limited data regarding associations between FI and race. The goal of this study was to estimate the prevalence of FI, and to secondarily identify demographic, lifestyle, and medical factors associated with FI, especially with regard to race.

METHODS

This was a planned secondary analysis of a population-based cross-sectional telephone interview survey of 2812 black and white community-dwelling women living in southeastern Michigan. The primary outcome measured was the prevalence of self-reported FI, defined as any loss of stool during the previous 12 months. Logistic regression modeling was used to identify characteristics independently associated with FI.

RESULTS

Of the subjects, 16.7% reported FI in the previous year. Fecal incontinence was approximately twice as common in white women (20%) as black women (11%). Factors associated with FI differed between the 2 races, although its prevalence in both racial groups increases with higher numbers of medical comorbidities, increased frequency of bowel movements per week, and depression.

CONCLUSIONS

One in 6 women report FI, although it occurs one-half as often in black as in white women. Although there are common characteristics shared by women with FI in both racial groups, white women experience FI in complex with other pelvic floor disorders. For black women, FI is an isolated pelvic floor disorder associated with mobility impairment.

Factors associated with care seeking among women with accidental bowel leakage

OBJECTIVE

The aim of this study was to characterize factors associated with care seeking among women with accidental bowel leakage (ABL).

METHODS

A secondary analysis of 938 women with ABL identified in a community-based Internet survey of 5817 US women 45 years or older was performed. Demographics, medical history, incontinence severity, quality of life, coping, and care seeking were assessed using questions derived from validated questionnaires. Accidental bowel leakage was defined as at least 1 episode of stool leakage in the past year in the absence of acute diarrheal illness. Women with ABL were asked, "Have you ever talked to a physician about accidental leakage of stool and/or gas?" and were designated "care seekers" if they responded affirmatively. Factors associated with care seeking on univariate analysis with P < 0.1 were included in a multivariate model.

RESULTS

The response rate overall was 85% (5817/6873) with 1096 women (19%) reporting ABL. Care-seeking data were available for 938 (86%). Of these, 85% were white, 6% were black/African American, 5% were of Hispanic/Latina/Spanish origin, and 4% other; median age was 55 to 59 years (range, 45 to 49, >75 years), and 87% were insured. Only 29% (268/938) of those with ABL sought care. Multivariate analysis demonstrated that care seekers were more likely to have a primary care physician (PCP), to have heard of ABL, and to have suffered longer with more severe leakage.

CONCLUSIONS

More than two thirds of women with ABL do not seek care. Because those with a PCP and those who have heard of the condition are more likely to seek care, educating the public about ABL and encouraging establishment of care and communication with a PCP may decrease silent suffering.

Injection of porous polycaprolactone beads containing autologous myoblasts in a dog model of fecal incontinence

PURPOSE

Few studies have examined whether bioengineering can improve fecal incontinence. This study designed to determine whether injection of porous polycaprolactone beads containing autologous myoblasts improves sphincter function in a dog model of fecal incontinence.

METHODS

The anal sphincter of dogs was injured and the dogs were observed without and with (n = 5) the injection of porous polycaprolactone beads containing autologous myoblasts into the site of injury. Autologous myoblasts purified from the gastrocnemius muscles were transferred to the beads. Compound muscle action potentials (CMAP) of the pudendal nerve, anal sphincter pressure, and histopathology were determined 3 months after treatment.

RESULTS

The amplitudes of the CMAP in the injured sphincter were significantly lower than those measured before injury (1.22 mV vs. 3.00 mV, P = 0.04). The amplitudes were not different between dogs with and without the injection of autologous myoblast beads (P = 0.49). Resting and squeezing pressures were higher in dogs treated with autologous myoblast beads (2.00 mmHg vs. 1.80 mmHg; 6.13 mmHg vs. 4.02 mmHg), although these differences were not significant in analyses of covariance adjusted for baseline values. The injection site was stained for smooth muscle actin, but showed evidence of foreign body inflammatory reactions.

CONCLUSION

This was the first study to examine whether bioengineering could improve fecal incontinence. Although the results did not show definite evidence that injection of autologous myoblast beads improves sphincter function, we found that the dog model was suitable and reliable for studying the effects of a potential treatment modality for fecal incontinence.

Long-term durability of sacral nerve stimulation therapy for chronic fecal incontinence

BACKGROUND

Limited data have been published regarding the long-term results of sacral nerve stimulation, or sacral neuromodulation, for severe fecal incontinence.

OBJECTIVES

The aim was to assess the outcome of sacral nerve stimulation with the use of precise tools and data collection, focusing on the long-term durability of the therapy. Five-year data were analyzed.

DESIGN

Patients entered in a multicenter, prospective study for fecal incontinence were followed at 3, 6, and 12 months and annually after device implantation.

PATIENTS

Patients with chronic fecal incontinence in whom conservative treatments had failed or who were not candidates for more conservative treatments were selected.

INTERVENTIONS

Patients with ≥ 50% improvement over baseline in fecal incontinence episodes per week during a 14-day test stimulation period received sacral nerve stimulation therapy.

MAIN OUTCOME MEASURES

Patients were assessed with a 14-day bowel diary and Fecal Incontinence Quality of Life and Fecal Incontinence Severity Index questionnaires. Therapeutic success was defined as ≥ 50% improvement over baseline in fecal incontinence episodes per week. All adverse events were collected.

RESULTS

A total of 120 patients (110 women; mean age, 60.5 years) underwent implantation. Seventy-six of these patients (63%) were followed a minimum of 5 years (maximum, longer than 8 years) and are the basis for this report. Fecal incontinence episodes per week decreased from a mean of 9.1 at baseline to 1.7 at 5 years, with 89% (n = 64/72) having ≥ 50% improvement (p < 0.0001) and 36% (n = 26/72) having complete continence. Fecal Incontinence Quality of Life scores also significantly improved for all 4 scales between baseline and 5 years (n = 70; p < 0.0001). Twenty-seven of the 76 (35.5%) patients required a device revision, replacement, or explant.

CONCLUSIONS

The therapeutic effect and improved quality of life for fecal incontinence is maintained 5 years after sacral nerve stimulation implantation and beyond. Device revision, replacement, or explant rate was acceptable, but future efforts should be aimed at improvement.

Accidental bowel leakage in the mature women's health study: prevalence and predictors

BACKGROUND

The 2007 National Institutes of Health incontinence consensus panel emphasised the need for classification and identification of persons at risk for faecal incontinence (FI).

OBJECTIVES

To explore the prevalence of FI; to characterise severity and 'bother'; and to identify factors associated with FI in a large sample of community-dwelling women.

DESIGN, SETTING, AND PARTICIPANTS

A cohort of US women ≥ 45 years old was surveyed via an internet-based questionnaire between September 2009 and April 2010.

MAIN OUTCOME MEASURE

Accidental leakage of liquid or solid stool at least once in the last 12 months.

KEY RESULTS

Eighty-five per cent of those surveyed (5817/6873) participated and were predominantly white, well educated and insured. The prevalence of FI at least once in the past year was 18.8% (1096/5817; 95% CI: 17.8-19.9%) and 97% of these women were bothered by this frequency of leakage. Among 938 respondents with FI, 71.1% (667) preferred the term 'accidental bowel leakage' (ABL) over faecal or bowel incontinence. Bowel disorders, urinary incontinence, stroke, age 55-64, diabetes mellitus and prior vaginal delivery were associated with an increased odds of FI, whereas being married, Black or American Indian/Alaska Native race/ethnicity, and income ≥ $40,000 per year were associated with a decreased odds of FI.

CONCLUSIONS

Nearly one-fifth of mature US women suffer from bothersome leakage of stool at least yearly and the overwhelming majority prefer the term 'Accidental Bowel Leakage.' Those with bowel disorders and urinary incontinence are most likely to experience ABL. Incorporating questions regarding ABL or bowel and bladder disorders into routine screening may aid in identifying silent sufferers of ABL.
