Faecal incontinence in adults

Anal incontinence incidence is high in patients with obesity prior to bariatric surgery: Prevalence, risks-factors

INTRODUCTION

Anal incontinence (AI) prevalence in general population is estimate to range from 1.4 to 19.5% (Wexner ≥ 1). Obesity could be an AI risk factor. However, AI prevalence in patients with obesity is not clearly established. The main objective of this study was to assess the prevalence of AI in patients with extreme obesity prior to bariatric surgery and to identify specific AI risk factors in this subset of patients.

MATERIAL

A cross-sectional study, in a tertiary referral center in obesity was performed during one year. Patients who presented criteria for bariatric surgery (BMI>40 or BMI > 35 with co-morbidities) were asked to fill in preoperative self-questionnaires. A Wexner score ≥ 3 was used to define AI to identified patients who had a clinic impact of AI, by frequency of symptoms or alteration of quality of life.

RESULTS

Two hundred and fifty patients were included. Corresponded to, 196 women (78.4%) and 54 men (21.6%). Median BMI was 44.53kg/m². AI was diagnosed in 41 patients (prevalence 16.4%, 95CI 0.59). Constipation, urinary incontinence and the history of pregnancy (P = 0.03, OR 2.79; P = 0.01, OR 3.53 and P=0.02, OR 4.71, respectively) were significantly associated with AI.

CONCLUSION

AI is frequently observed in patients with extreme obesity scheduled for bariatric surgery and should be routinely evaluated. Modifiable risk factors as constipation should be manage before surgery as well as the specific management of AI, to prevent AI exacerbation after surgery. The choice of bariatric surgical procedure should be discussed and evaluated for the treatment of patients with obesity and AI.

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.

Efficacy of Tibial Nerve Stimulation on Fecal Incontinence in Patients With Low Anterior Resection Syndrome Following Surgery for Colorectal Cancer

OBJECTIVE

To systematically review the available literature on the efficacy of tibial nerve stimulation on faecal incontinence and quality of life in adult patients with low anterior resection syndrome following surgery for colorectal cancer.

METHODS

A primary search of electronic databases was conducted adopting a combination of search terms related to the following areas of interest: "efficacy", "tibial nerve stimulation" and "low anterior resection syndrome". A secondary search of the grey literature was performed in addition to checking the reference list of included studies and review papers. The review was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. A descriptive analysis was used to integrate the review findings.

RESULTS

Five distinct studies involving 116 patients met the inclusion criteria for the review. The included studies suggest that tibial nerve stimulation may have a positive effect on faecal incontinence and quality of life in some patients with low anterior resection syndrome and might be considered as an additional treatment option.

CONCLUSION

There were a limited number of studies and a great degree of heterogeneity of evidence due to differences in participants' baseline characteristics, dropout rates, and follow-up periods. Further research adopting validated, consistent, and complex outcome assessment methods is recommended to determine the efficacy of tibial nerve stimulation for treatment of patients with low anterior resection syndrome.

Pharmacotherapy and the Role of Pharmacists in Rehabilitation Medicine

Pharmacotherapy is important in older patients undergoing rehabilitation because such patients, especially those with frailty and physical disabilities, are susceptible to drug-related functional impairment. Drug-related problems include polypharmacy, potentially inappropriate medications (PIMs), and potential prescription omissions. These problems are associated with adverse drug events such as dysphagia, depression, drowsiness, falls and fractures, incontinence, decreased appetite, and Parkinson's syndrome, leading to impaired improvement in activities of daily living (ADL), quality of life (QOL), and nutritional status. Moreover, the anticholinergic burden is associated with impaired physical and cognitive functions. Therefore, pharmacist-centered multidisciplinary pharmacotherapy should be performed to maximize rehabilitation outcomes. Pharmacotherapy includes a review of all medications, the assessment of drug-related problems, goal setting, correction of polypharmacy and PIMs, monitoring of drug prescriptions, and reassessment of drug-related problems. The goal of pharmacotherapy in rehabilitation medicine is to optimize drug prescribing and to maximize the improvement of ADL and QOL as patient outcomes. The role of pharmacists during rehabilitation is to treat patients as part of multidisciplinary teams and as key members of nutritional support teams. In this review, we aim to highlight existing evidence regarding pharmacotherapy in older adults, including drug-related functional impairment and the association between pharmacotherapy and functional, cognitive, and nutritional outcomes among patients undergoing rehabilitation. In addition, we highlight the important role of pharmacists in maximizing improvements in rehabilitation outcomes and minimizing drug-related adverse effects.

Fecal incontinence in nonpregnant nulliparous women aged 25 to 64 years-a randomly selected national cohort prevalence study

BACKGROUND

The extent to which fecal incontinence is associated with obstetrical history or pelvic floor injuries is still a controversial and unresolved issue. One crucial first step toward answering this question is the need to study fecal incontinence in nonpregnant, nulliparous women.

OBJECTIVE

The aim of this study was to present detailed, descriptive measures of the accidental leakage of liquid or solid stool and gas in a randomly selected, large national cohort of nonpregnant, nulliparous women aged 25 to 64 years.

STUDY DESIGN

The Swedish Total Population Register identified the source population. Four independent, age-stratified, simple random samples in a total of 20,000 nulliparous women aged 25 to 64 years were drawn from 625,810 eligible women. Information was collected in 2014 using postal and web-based questionnaires. The 40-item questionnaire included questions about the presence and frequency of the leakage of solid and liquid stool and gas, which provided the basis for the generic terms fecal and anal incontinence. Statistical analyses of the differences between the groups were performed using the Fisher's exact test for dichotomous variables and the Mann-Whitney U-test for continuous variables. The trend between >2 ordered categories of dichotomous variables was analyzed with Mantel-Haenszel statistics. When analyzing the trend between multiple ordered vs nonordered categorical variables, the Kruskal-Wallis test was used. The age-related probability and risk increase per 10 years for incontinence parameters was calculated from logistic regression models adjusted for body mass index.

RESULTS

The study population was 9197 women, and the response rate was 52.2%, ranging from 44.7% in women aged 25 to 34 years to 62.4% among those from 55 to 64 years. All the types of incontinence, except severe isolated gas incontinence, increased with age up to 64 years. The estimated probability of fecal incontinence was 8.8% at age 25 years and 17.6% at age 64. The leakage of liquid stool was dominant, occurring in 93.1% (95% confidence interval, 91.4-94.5) of the women with fecal incontinence, whereas leakage of solid stool occurred in 33.9% (95% confidence interval, 31.1-36.7), of which approximately 80% also had concomitant leakage of liquid stool. The leakage of liquid stool increased markedly up to age 65, whereas the increase in the isolated leakage of solid stool was negligible across all ages (overall <0.4%). Liquid and solid stool, separate or in combination, co-occurred with gas in approximately 80%. The distribution pattern of the different types of leakage, single or combined, was similar in all the age groups. Both age and body mass index (kg/m²) were risk factors for fecal incontinence (P<.0001), with an interaction effect of P=.16.

CONCLUSION

Abnormal stool consistency has been identified as the strongest risk factor for accidental bowel leakage. The same pattern characterized by a dominance of liquid stool and gas leakage, prevalent concomitant leakage of solid and liquid stool, and a negligible rate of isolated leakage of solid feces was observed across all ages. The low rates of isolated leakage of solid stool support the impression that dysfunction of the continence mechanism of the pelvic floor had a negligible role for bowel incontinence, which is essential information for comparison with women with birth-related injuries.

Commodity analysis of medical products used in adult incontinence

There are problems people don’t want to talk about, and one of them is incontinence in adults. This is a fairly common and delicate problem. It negatively affects human life. This most often applies to people with disabilities and bedridden patients. People have to change their usual way of life, give up their favorite activities, there is a constant need to stay at home. Walking, attending events are difficult. All this has a corresponding effect on the psychological health of a person. In such a situation, it is advisable to use diapers for adults. This is a modern hygienic product that is intended to make life easier for people suffering from various forms of incontinence. Diapers are similar in shape to baby diapers, but they are adapted to the size of an adult. This is a great option for the care of patients who are bedfast or in a wheelchair.

Accidental Bowel Leakage/Fecal Incontinence: Evidence-Based Management

Fecal incontinence is a highly prevalent and debilitating condition that negatively impacts quality of life. The etiology is often multifactorial and treatment can be hindered by lack of understanding of its mechanisms and available treatment options. This article reviews the evidence-based update for the management of fecal incontinence.

Neuromodulation

Sacral neuromodulation (SNM) has been available in the United States for more than 20 years and is a guideline-recommended therapy by both the American Urological Association and the American Society of Colon and Rectal Surgeons, with proven long-term success for urinary urgency incontinence, urinary urgency frequency, nonobstructive urinary retention, and fecal incontinence. Initially the therapy involved a more invasive surgical approach that included a large cut down over the sacrum. This article reviews recent advancements in SNM therapy including updates in best practices for implant technique, technological innovations, and the new clinical literature relevant to contemporary practice.

Fecal Incontinence in the Elderly

Fecal incontinence can be a challenging and stigmatizing disease with a high prevalence in the elderly population. Despite effective treatment options, most patients do not receive care. Clues in the history and physical examination can assist the provider in establishing the diagnosis. Direct inquiry about the presence of incontinence is key. Bowel disturbances are common triggers for symptoms and represent some of the easiest treatment targets. We review the epidemiology and impact of the disease, delineate a diagnostic and treatment approach for primary care physicians to identify patients with suspected fecal incontinence and describe appropriate treatment options.

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).

Japanese Practice Guidelines for Fecal Incontinence Part 3 -Surgical Treatment for Fecal Incontinence, Fecal Incontinence in a Special Conditions- English Version

In Japan, the surgical treatment for fecal incontinence (FI) can be performed using minimally invasive surgery, such as anal sphincteroplasty and sacral neuromodulation (SNM), as well as antegrade continence enema (ACE), graciloplasty, and stoma construction. In addition, currently, several other procedures, including biomaterial injection therapy, artificial bowel sphincter (ABS), and magnetic anal sphincter (MAS), are unavailable in Japan but are performed in Western countries. The evidence level of surgical treatment for FI is generally low, except for novel procedures, such as SNM, which was covered by health insurance in Japan since 2014. Although the surgical treatment algorithm for FI has been chronologically modified, it should be sequentially selected, starting from the most minimally invasive procedure, as FI is a benign condition. Injuries to the neural system or spinal cord often cause disorders of the sensory and motor nerves that innervate the anus, rectum, and pelvic floor, leading to the difficulty in controlling bowel movement or FI and/or constipation. FI and constipation are closely associated; when one improves, the other tends to deteriorate. Patients with severe cognitive impairment may present with active soiling, referred to as "incontinence" episodes that occur as a consequence of abnormal behavior, and may also experience passive soiling.

Updates in treating fecal incontinence in women

PURPOSE OF REVIEW

Fecal incontinence is a chronic condition that can significantly affect a woman's quality of life. The pathogenesis of fecal incontinence is multifaceted and management ranges from supportive care, medical therapy to more invasive surgical procedures. This review will discuss the recent advancements in treating fecal incontinence.

RECENT FINDINGS

The pelvic floor disorder consortium has created a consensus document with recommendations on pelvic floor symptom measurement tools, patient-reported instruments, and questionnaires that should be used when evaluating fecal incontinence. There is new robust data reinforcing the importance of conservative management prior to proceeding with more invasive treatment. Lastly, several novel therapies that were developed in the past decade now have longer term data on safety and efficacy.

SUMMARY

Management of fecal incontinence is challenging, as no one therapy has been proven to be predominately effective. We should continue to first optimize patients with conservative therapy followed by induction of more advanced therapies. There needs to be continued efforts to develop and evaluate effective treatment guidelines and therapies for fecal incontinence.

Percutaneous tibial nerve stimulation can improve symptoms and quality of life in selected patients with faecal incontinence - A single-centre 5-year clinical experience

INTRODUCTION

Faecal incontinence is a debilitating condition that affects a significant proportion of the population. Conservative management remains the mainstay of treatment but surgical intervention such as neuromodulation can be indicated in cases refractory to medical therapy.

AIM

The aim of this study was to review the outcomes of patients who underwent percutaneous tibial nerve stimulation (PTNS) for faecal incontinence and urgency in a single institution over five years.

RESULTS

Eighty-one patients completed the 12-week trial of PTNS with a success rate of 80% (n = 64/81). Rates of faecal incontinence and urgency were reduced from 13 episodes per fortnight to 3 and from 10 to 3 respectively. Over a median follow up of 2 years (range 0-5 years) reduction in rates of faecal urgency and incontinence were maintained. Quality of life parameters were measured using a variety of established questionnaires. Improvements were observed in the majority of parameters that were maintained throughout the follow up period.

CONCLUSION

Percutaneous tibial nerve stimulation is one of the forms of neuromodulation available for the treatment of faecal incontinence and urgency in patients who failed conservative management. This study has shown that in carefully selected, motivated patients, the use of PTNS in conjunction with regular counseling from a specialist practitioner in pelvic floor disorders can improve both the symptoms and quality of life of patients with faecal urgency and mild faecal incontinence with improvements in symptomology maintained for up to 5 years.

Posterior Tibial Nerve Stimulation in Fecal Incontinence: A Systematic Review and Meta-Analysis

Introduction:

The present systematic review and meta-analysis aims to investigate the role of Posterior Tibial Nerve Stimulation (PTNS) in the control of Fecal Incontinence (FI).

Methods:

Two independent reviewers extensively searched in the electronic databases of Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, CINAHL, and Scopus for the studies published until the end of 2016. Only randomized clinical trials were included. The studied outcomes included FI episodes, FI score, resting pressure, squeezing pressure, and maximum tolerable pressure. The data were reported as Standardized Mean Differences (SMD) with 95% confidence interval.

Results:

Five articles were included in the present study (249 patients under treatment with PTNS and 239 in the sham group). Analyses showed that PTNS led to a significant decrease in the number of FI episodes (SMD=−0.38; 95% CI: −0.67–0.10; P=0.009). Yet, it did not have an effect on FI score (SMD=0.13; 95% CI: −0.49–0.75; P=0.68), resting pressure (SMD=0.12; 95% CI: −0.14–0.37; P=0.67), squeezing pressure (SMD=−0.27; 95% CI: −1.03–0.50; P=0.50), and maximum tolerable pressure (SMD=−0.10; 95% CI: −0.40–0.24; P=0.52).

Conclusion:

Based on the results, it seems that the prescription of PTNS alone cannot significantly improve FI.

Iatrogenic constipation from barium blockade: A case report

Barolith, a mixture of inspissated barium and feces, is a rare complication of barium-contrast studies that lead to intestinal obstruction. With the high morbidity associated with barolith impaction, we recommend that physicians be more aware of complications, increase prompt diagnosis, and initiation of laxatives once discovered.

Mechanical inserts for the treatment of faecal incontinence: A systematic review

Objective: To perform a systematic review of the literature to examine original research on the role of mechanical inserts, both vaginal and anal, for the treatment of faecal incontinence (FI).

Materials and methods: We searched the PubMed, Cochrane Library, and ClinicalTrials.gov databases for any peer-reviewed original research in English on the role of mechanical inserts for the treatment of FI.

Results: We identified 35 unique citations. After title review and exclusion of articles not reporting original research, eight publications were included in the final review: two focused on vaginal inserts and six focused on anal inserts. Limited evidence indicates that both vaginal and anal inserts can be an effective and safe therapeutic option for patients with FI.

Conclusions: Data regarding vaginal and anal mechanical inserts for the treatment of FI, albeit limited, suggest that inserts can be included in a discussion of therapeutic options for a patient with FI. Further studies are needed to elucidate long-term usability, efficacy, and safety.

Anal incontinence after caesarean and vaginal delivery in Sweden: a national population-based study

BACKGROUND

Elective caesarean delivery is increasing rapidly in many countries, and one of the reasons might be that caesarean delivery is widely believed to protect against pelvic floor disorders, including anal incontinence. Previous studies on this issue have been small and with conflicting results. The aim of present study was to compare the risk of developing anal incontinence in women who had a caesarean delivery, in those who had a vaginal delivery, and in two age-matched control groups (nulliparous women and men).

METHODS

In this observational population-based study, we included all women in the Swedish Medical Birth Register who gave birth by caesarean delivery or vaginal delivery during 1973-2015 in Sweden and were diagnosed with anal incontinence according to ICD 8-10 in the Swedish National Patient Register during 2001-15. Exclusion criteria were multiple birth delivery, mixed vaginal and caesarean delivery, and four or more deliveries. We compared the diagnosis of anal incontinence between women previously delivered solely by caesarean delivery and those who solely had delivered vaginally. We also compared it with two age-matched control groups of nulliparous women and men from the Swedish Total Population Register. Finally, we analysed risk factors for anal incontinence in the caesarean delivery and vaginal delivery groups.

FINDINGS

3 755 110 individuals were included in the study. Between 1973 and 2015, 185 219 women had a caesarean delivery only and 1 400 935 delivered vaginally only. 416 (0·22 %) of the 185 219 women in the caesarean delivery group were diagnosed with anal incontinence compared with 5171 (0·37%) of 1 400 935 women in the vaginal delivery group. The odds ratio (OR) for being diagnosed with anal incontinence after vaginal delivery compared with caesarean delivery was 1·65 (95% CI 1·49-1·82; p<0·0001). When the combination vaginal delivery and caesarean delivery was compared with the nulliparous control group, the OR of being diagnosed with anal incontinence was 2·05 (1·92-2·19; p<0·0001). For the nulliparous women compared with men, the OR for anal incontinence was 1·89 (1·75-2·05; p<0·0001). The strongest risk factors for anal incontinence after vaginal delivery were high maternal age, high birthweight of the child, and instrumental delivery. The only risk factor for anal incontinence after caesarean delivery was maternal age.

INTERPRETATION

The risk of developing anal incontinence increases after pregnancy and delivery. Women with known risk factors for anal incontinence should perhaps be offered a more qualified post-partum examination to enable early intervention in case of injury. Further knowledge for optimal management are needed.

Efficacy of Bilateral Transcutaneous Posterior Tibial Nerve Stimulation for Fecal Incontinence

CONTEXT

Posterior tibial nerve stimulation is a new second-line treatment for refractory fecal incontinence.

OBJECTIVE

To assess the efficacy of bilateral transcutaneous posterior tibial nerve stimulation (BTPTNS) for treatment of fecal incontinence in Japanese patients and its impact on quality of life.

DESIGN

A prospective observational-interventional study was conducted from May 2015 to June 2017 in patients with fecal incontinence in whom conservative treatment had failed. All patients received a 30-minute session of stimulation twice weekly for 6 consecutive weeks. Evaluation at baseline and at 6 weeks involved the Wexner score, Fecal Incontinence Quality of Life (FIQL) questionnaire, and anal manometry. Patients recorded episodes of incontinence in a weekly diary.

MAIN OUTCOME MEASURES

Reduction of 50% or greater in incontinence episodes, decreased Wexner score, and improved FIQL scores.

RESULTS

Twenty-two patients with a median age of 64.1 years (range, 26-81 years) and men:women ratio of 9:13 completed BTPTNS. Mean episodes of fecal incontinence were significantly reduced from 4.7 to 1.5 (p < 0.05). An improvement of 50% or better in episodes of fecal incontinence was achieved in 77.2% of patients. The median Wexner score significantly decreased from 10.2 to 6.9 (p < 0.05). The median FIQL score improved from 2.7 to 3.1 (p = 0.06), and significant improvement was seen in the embarrassment domain (2.2 vs 2.8, p < 0.05). Resting and squeezing anal pressures revealed no significant changes.

CONCLUSION

Our findings suggest that BTPTNS is safe and well tolerated and may improve symptoms of fecal incontinence. This technique offers an additional noninvasive, less expensive form of treatment.

Medium-term outcome of percutaneous tibial nerve stimulation in the treatment of fecal incontinence

INTRODUCTION

Fecal incontinence (FI) is a multifactorial disease that affects patients' quality of life. The aim of this study was to evaluate the efficacy of posterior tibial nerve stimulation (PTNS) in the treatment of FI and to assess the medium-term results.

METHODS

A prospective cohort of patients with FI treated with PTNS between 2012 and 2014 was analysed. Endoluminal ultrasound and anorectal physiologic studies were performed in all patients. The efficacy of PTNS was assessed using a validated questionnaire (Cleveland Clinic Incontinence Score) at baseline, after treatment, and 2 years later. The Vaizey score was also used at 2-year follow-up to assess urge incontinence.

RESULTS

Fifty-six patients (38 females; mean age 59.7 years) with FI were treated. The causes of FI were mainly obstetric injury and previous colorectal surgery. A decrease of 50% from baseline CCIS was seen in 41.1% of patients after PTNS. One-third maintained a minimum of 50% decrease of their initial CCIS after 2 years. Comparing CCIS at baseline, after treatment, and at 2-year follow-up, a statistically significant difference was observed (p < 0.0001 and p < 0.0004 respectively). Medium-term improvement was not maintained in patients with passive and mixed FI, while it was maintained in those with urge incontinence. At 2 years, patients with mild incontinence maintained the greatest response.

CONCLUSIONS

PTNS is a safe, effective, non-invasive treatment for FI with good results in almost half of the patients at the end of the treatment. There is also an acceptable maintained response at 2-year follow-up. It seems to be most successful in patients with mild incontinence and urge incontinence.

Pubovisceral muscle and anal sphincter defects in women with fecal or urinary incontinence after vaginal delivery

BACKGROUND

Vaginal delivery is the most frequent cause of direct anal sphincter trauma as well as pelvic floor muscle defects in women with corresponding signs and symptoms. The aim of the present study was to identify anatomical and functional abnormalities of the anal canal and pelvic floor in women who had had a vaginal delivery and determine the relationship between such abnormalities and the symptoms and severity of fecal incontinence (FI).

METHODS

Consecutive female patients with symptoms of fecal and/or urinary incontinence were recruited through the colorectal and gynecological outpatient clinics at two large university hospitals and were eligible if they had had at a vaginal delivery. All women were assessed for symptoms FI by means of the Cleveland Clinic Florida Incontinence Scale (CCFIS) and for urinary incontinence symptoms, including the presence of complaints of any involuntary leakage of urine, leakage on exertion, sneezing, or coughing, and/or leaking or losing urine associated with an urge to urinate. All women underwent anorectal and endovaginal three-dimensional ultrasonography and anal manometry. The extent of the anal sphincter and PVM defects identified by ultrasound was scored from 1 to 6 based on the longitudinal involvement of the external and internal anal sphincter, the radial angle of the anterior external anal sphincter defect and the longitudinal involvement of the PVM.

RESULTS

There were 130 women and 89 (68%) had at least one defect of the anal sphincter or the pubovisceral muscle or both (42/32% had a pubovisceral muscle defect with or without sphincter defects, 47/36% women had an intact pubovisceral muscle but sphincter defect); and 41 (32%) had intact anal sphincter and pubovisceral muscles. The mean levator hiatus area at rest in women with anal sphincter and/or pubovisceral muscle defects was 18 (± 4 SD) which was significantly greater than in women with no defects (16 ± 3 SD; p = 0.01). Women with PVM defects had significantly higher ultrasound scores (median ultrasound score = 4/range 1-10 vs Intact = 2/range 2-5), indicating more extensive defects (p = 0.001). Bivariate analysis revealed a positive association (p < 0.05) between increasing FI symptom severity (CCFIS score) and women with PVM defects (ρ = 0.6913). Within the group of women with defects mean maximum anal squeeze pressure was significantly lower in women with PVM defect (mean 73 ± 34 SD mmHg vs mean 93 ± 38 SD; p = 0.04). Women with PVM defects had significantly higher median CCFIS scores (median score, 7/range 0-16) compared to women with intact PVM (4/range 0-10) (p < 0.001). There was a significant positive correlation between the CCFIS and ultrasound scores (ρ = 0.625; p < 0.001). Bivariate analysis revealed a negative correlations between the CCFIS score and the lengths of the anterior EAS (ρ = - 0.5621, p < 0.001), IAS (ρ = - 0.40, p < 0.001) and the area of the levator hiatus (ρ = 0.5211, p = 0.001). However, no significant correlations were observed between CCFIS scores and the gap measurement (ρ = 0.101; p = 0.253) or the resting (ρ = - 0.08, p = 0.54) or squeeze pressure (ρ = - 0.12; p = 0.34) values on anal manometry. The variables associated with worsening FI symptom severity (CCFIS score) that remained significant in multiple linear regression included the shorter lengths of the anterior EAS and/or the lengths of the anterior IAS and increased area of the levator hiatus.

CONCLUSIONS

The study data demonstrate that half of the women had combined defects of PVM and sphincter. There were correlations between anatomical abnormalities including the anal sphincter and/or pubovisceral muscle defects with decrease in the anal pressures and increased severity of FI.

Conservative treatment of severe defecatory urgency and fecal incontinence: minor strategies with major impact

BACKGROUND

Bowel disturbances have been identified as the most important risk factor for fecal incontinence (FI). However, few studies have evaluated the impact of fiber supplementation. Our aim was to assess the correlation between the improvement in stool consistency by fiber supplementation and the changes in urgency and number of FI episodes and in the QoL of patients with FI.

METHODS

Eighty-three patients who came to our institution with FI and/or fecal urgency associated with loose stools or diarrhea were prospectively included in the study The intervention included dietary advice and methylcellulose 500 mg every 8 h for 6 weeks. All assessments were carried out at baseline and 6 weeks after the start of the intervention, and included a Bristol Stool Scale, a 3-week bowel diary, the St Mark's score, the Fecal Incontinence Quality of Life scale (FIQL) and a bowel satisfaction score.

RESULTS

Sixty-one patients completed the study. At baseline 50 reported episodes of urge incontinence, while 11 did not report FI episodes because they rarely left home to avoid leakage. The Bristol score improved to normal stools in 65.6% of patients after treatment. Bowel diaries showed a statistically significant reduction in the number of bowel movements, urge episodes, urge fecal incontinence episodes and soiling per week. The St Mark's score and the bowel satisfaction score significantly improved after methylcellulose and overall deferment time also increased. FIQL significantly improved in two subdomains (lifestyle, coping/behavior). Thirty-one patients (51.7%) were discharged with methylcellulose as the only treatment.

CONCLUSIONS

FI may significantly improve with methylcellulose in selected cases. Assessment of fecal consistency and initial treatment with methylcellulose could be started at primary care level to reduce the need for specialist referral.

A randomized controlled trial of four different regimes of biofeedback programme in the treatment of faecal incontinence

AIM

Biofeedback is an established, effective and non-invasive treatment for faecal incontinence (FI). The aim was to compare the effectiveness of four different biofeedback treatment regimes.

METHOD

This was a randomized control trial of patients with FI, stratified into two groups (metropolitan and rural) and then randomized into two subgroups (groups 1 and 2 within metropolitan, groups 3 and 4 within rural) with varying face-to-face and telephone biofeedback components. All patients received standardized counselling and education, dietary modification and the use of anti-diarrhoeal medications. Group 1 received four monthly face-to-face biofeedback treatments, groups 2 and 3 received one face-to-face biofeedback followed by telephone biofeedback and group 4 received a one-off face-to-face biofeedback treatment. Primary outcomes were patient-assessed severity of FI and quality of life as assessed by the 36-item Short Form Health Survey and direct questioning of objectives. Secondary outcomes included St Mark's incontinence score, anxiety, depression and anorectal physiology measures (resting, squeeze pressures; isotonic, isometric fatigue times).

RESULTS

Between 2006 and 2012, 351 patients were recruited. One patient died leaving 350 for analysis. 332 (95%) were women. Mean age was 60 (SD = 14). All groups had significant improvements in FI, quality of life, incontinence score and mental status (P < 0.001 each). There were no differences in improvements in FI between groups although patient satisfaction was less with reduced face-to-face contact. There were modest improvements in isotonic and isometric fatigue times suggesting improved sphincter endurance (both P < 0.001).

CONCLUSION

Biofeedback is effective for FI. Although face-to-face and telephone biofeedback is not necessary to improve FI, it is important for patient satisfaction.

Patient-Controlled Biofeedback Device for the Treatment of Fecal Incontinence: A Pilot Study

Although biofeedback has been used as a first-line therapy for fecal incontinence, it is known to be time consuming and demands attendance to a hospital during the whole period of treatment. In this study, we describe a new biofeedback device specifically developed for home treatment of fecal incontinence, which consists of a microprocessor controlled unit able to register and store the anal pressure waves corresponding to exercises performed by patients at home. In order to test the new device, a pilot study including ten patients with fecal incontinence was conducted. Evaluation of patients before and after the biofeedback training showed significant improvement in manometric and clinical parameters of anal continence. The new method may improve compliance of patients with the training program and reduce their need to be supervised during the treatment. It might represent a new alternative for the treatment of fecal incontinence.

Current practice of continence advisors in managing faecal incontinence in the United Kingdom: results of an online survey

AIM

To investigate the current practice of continence advisors in the United Kingdom.

METHOD

Continence advisors were contacted by email or letter to participate in a survey. The survey contained 27 questions which addressed the practice of each continence advisor, their knowledge of continence management and the adequacy of their training.

RESULTS

Two hundred and twenty-six out of a total of 448 continence advisors (50.4%), responded. One hundred and seventy (76.9%) advisors treated both faecal and urinary incontinence, 51 (23.1%) treated urinary incontinence. Thirty-six advisors (16.1%) were lone workers and 130 (58.6%) had more than 10 years' experience. The majority of the advisors (75.6%) performed a digital rectal examination as part of their assessment. Regarding the management of faecal incontinence, 148 prescribed suppositories, 127 offered enemas and 147 advised on rectal irrigation. Most of the advisors taught pelvic floor exercises (n = 207) and urge resistance techniques (n = 188). One hundred and fifty-nine (87.4%) prescribed the Peristeen Coloplast^® anal plug and 78 (47.6%) prescribed the Renew^® anal insert. Eighty-nine advisors (42.6%) felt they had not been adequately trained to provide a bowel continence service.

CONCLUSION

The majority of continence advisors in the UK manage faecal incontinence. They are able to initiate a broad range of conservative treatment options; however, almost half of the advisors who answered the survey felt inadequately trained and may be better supported by further training.

Fecal Incontinence Is Associated With Mortality Among Older Adults With Complex Needs: An Observational Cohort Study

OBJECTIVES

Fecal incontinence (FI) is a problem in growing older populations. Validating a suspected association between FI and mortality in community dwelling older adults could lead to improved planning for and management of the increasing complex older population. In a large cohort of New Zealand older adults, we assessed the prevalence of FI, urinary incontinence (UI), combined FI and UI, and their associations with mortality.

METHODS

This study consisted of a retrospective analysis of international standardized geriatric assessment-home care (InterRAI-HC) data from community-dwelling adults aged 65 years or older, who met the criteria required for the InterRAI-HC, having complex needs and being under consideration for residential care. The prevalence of UI and FI was analyzed. Data were adjusted for demography and 25 confounding factors. Mortality was the primary outcome measure.

RESULTS

The total cohort consisted of 41,932 older adults. Both UI and FI were associated with mortality (P<0.001), and risk of mortality increased with increased frequency of incontinence. In the adjusted model, FI remained significantly related to survival (P<0.001), whereas UI did not (P=0.31). Increased frequency of FI was associated with an increased likelihood of death (hazard ratio 1.28).

CONCLUSIONS

This large national study is the first study to prove a statistically significant relationship between FI and mortality in a large, old and functionally impaired community. These findings will help improve the management of increasingly complex older populations.

A pilot study assessing the efficacy of posterior tibial nerve stimulation in the treatment of low anterior resection syndrome

BACKGROUND

Low anterior resection for rectal cancer often results in severe bowel dysfunction, specifically low anterior resection syndrome (LARS), with symptoms such as incontinence, urgency, and frequent bowel movements. Percutaneous tibial nerve stimulation (PTNS) resulted in a high rate of success in patients with fecal incontinence. The aim of this study was to evaluate the effectiveness of treatment with PTNS in LARS and to identify predictors of the outcome of the technique.

METHODS

The study was conducted from May 2012 to April 2015 at the Alvaro Cunqueiro Hospital, University Hospital Complex of Vigo, Spain. Ten patients with LARS were recruited consecutively. All patients underwent 2 sessions per week (30 min each one) for 6 weeks. Patients were followed for 3 weeks, and those who had a significant clinical improvement were recruited to a second phase of PTNS. Some patients presenting with relapse during follow-up underwent an additional phase of PTNS. Outcome measures included Wexner scores, quality of life scores, and urgency of defecation.

RESULTS

Three patients did not complete the treatment due to poor response in the first phase. Incontinence was reduced in the remaining seven of ten patients. The median Wexner score at initial patient evaluation was 14 (IQR 10.75-18.5), which decreased to 10 (IQR 6.5-18) after treatment (p = 0.034). A statistically significant improvement was demonstrated in quality of life scale, lifestyle, depression, and daily defecation urgency (p < 0.05). LARS Score improvement was observed in five patients (50%) with a total resolution of LARS in 2 (20%).

CONCLUSIONS

PTNS is an ambulatory treatment that could play an important role in the context of a multimodal treatment approach in patients with LARS. It could be a first-line treatment to identify non-responders to conservative management who need different and more invasive treatments.

Pathophysiology and Therapeutic Options for Fecal Incontinence

Fecal incontinence (FI), defined as the involuntary loss of solid or liquid feces through the anus is a prevalent condition with significant effects on quality of life. FI can affect individuals of all ages and in many cases greatly impairs quality of life but, incontinent patients should not accept their debility as either inevitable or untreatable. The severity of incontinence can range from unintentional elimination of flatus to the complete evacuation of bowel contents. It is reported to affect up to 18% of the population, with a prevalence reaching as high as 50% in nursing home residents. However, FI is often underreported, thus obscuring its true prevalence in the general population. The options for treatment vary according to the degree and severity of the FI. Treatment can include dietary and lifestyle modification, certain medications, biofeedback therapy, bulking agent injections, sacral nerve stimulation as well as various types of surgery. In this article, we aim to provide a comprehensive review on the diagnosis and management of FI.

Perspectives From Patients and Care Providers on the Management of Fecal Incontinence: A Needs Assessment

BACKGROUND

A large proportion of Canadians experience fecal incontinence, with no avenue for effective treatments. The Ottawa Hospital has recently started a percutaneous tibial nerve stimulation program for patients who have not improved with conservative efforts.

OBJECTIVE

As part of this program implementation, a qualitative needs assessment was undertaken to better define successful outcomes and to identify barriers for program sustainability.

DESIGN

This was a cross-sectional, qualitative study involving standardized, semistructured interviews.

SETTINGS

The study was conducted at a single tertiary care center.

PATIENTS

Patients experiencing fecal incontinence, as well as nurses, physical therapists, and physicians, were enrolled in the study.

MAIN OUTCOME MEASURES

Interview questions revolved around success definitions, barriers, and promoters of fecal incontinence care. Transcripts were analyzed to develop themes surrounding fecal incontinence care.

RESULTS

Twelve interviews were undertaken raising a total of 17 different themes. Barriers to fecal incontinence care included education for both the care provider and patients. Access issues for treatments were also highlighted. Promoters of fecal incontinence care were reflected by the impact that it has on quality of life, personal hygiene, psychological burden, and activity and productivity. The definition of fecal incontinence success was focused on improvements in quality of life rather than a numerical reduction of incontinence episodes.

LIMITATIONS

This study was limited in its small number of interviews conducted. We were unable to identify patients who were unable to seek out care for fecal incontinence.

CONCLUSIONS

Patient and care provider education surrounding fecal incontinence is lacking. Furthermore, access for effective treatments is a real barrier for Canadians experiencing fecal incontinence. Programs should focus on improvement of overall quality of life rather than a reduction of incontinence episodes.

Fecal incontinence - Challenges and solutions

Fecal incontinence is not a diagnosis but a frequent and debilitating common final pathway symptom resulting from numerous different causes. Incontinence not only impacts the patient’s self-esteem and quality of life but may result in significant secondary morbidity, disability, and cost. Treatment is difficult without any panacea and an individualized approach should be chosen that frequently combines different modalities. Several new technologies have been developed and their specific roles will have to be defined. The scope of this review is outline the evaluation and treatment of patients with fecal incontinence.

Evidence-Based Update on Treatments of Fecal Incontinence in Women

Fecal incontinence is a highly prevalent and distressing condition that has a negative impact on quality of life. The etiology is often multifactorial, and the evaluation and treatment of this condition can be hindered by a lack of understanding of the mechanisms and currently available treatment options. This article reviews the evidence-based update for the management of fecal incontinence.

The Epidemiology of Pelvic Floor Disorders and Childbirth: An Update

Using a lifespan model, this article presents new scientific findings regarding risk factors for pelvic floor disorders (PFDs), focusing on the role of childbirth in the development of single or multiple coexisting PFDs. Phase I of the model includes predisposing factors, such as genetic predisposition and race. Phase II includes inciting factors, such as obstetric events. Prolapse, urinary incontinence (UI), and fecal incontinence (FI) are more common among vaginally parous women, although the impact of vaginal delivery on risk of FI is less dramatic than prolapse and UI. Phase III includes intervening factors, such as age and obesity.

Psychological resilience and active social participation among older adults with incontinence: a qualitative study

OBJECTIVES

Incontinence restricts participation in social activities among older adults. However, some older adults participate in social activities despite this condition. This study aimed to describe how older adults with incontinence could be resilient and actively participate in social activities.

METHODS

We conducted semi-structured interviews with 11 socially active older adults with incontinence (age 70-90; nine women and two men) at their homes or in private areas of day-service centres in Chiba, Japan. We coded salient narratives by using thematic analysis and extracted themes. Finally, we developed a conceptual model and illustrated the interactions among themes.

RESULTS

We identified seven themes that affected active social participation; five of these pertained to psychological characteristics ('motivation to be socially active', 'psychological stress of incontinence', 'desire to interact with others', 'willingness to perform physical exercise', and 'confidence in managing incontinence') and the remaining two pertained to supporting environmental factors ('assistive devices' and 'accessible toilet'). Three psychological themes ('desire to interact with others', 'willingness to perform physical exercise', and 'confidence in managing incontinence') were intertwined with supporting environmental factors and increased the participants' 'motivation to be socially active'.

CONCLUSION

Older adults with incontinence can actively participate in the society when they have desire to interact with others, willingness to perform physical exercise, and confidence in managing incontinence. These psychological characteristics are important for being resilient in the face of incontinence and for active social participation.

Short-term outcome of percutaneous posterior tibial nerve stimulation (PTNS) for the treatment of faecal incontinence

BACKGROUND

The aim of the present study was to establish the efficacy of percutaneous posterior tibial nerve stimulation (PTNS) in treating flatal, urge and passive faecal incontinence (FI).

METHODS

A prospective study with 55 patients with FI was carried out. Clinical anamnesis, physical examination, a reverse visual analogue scale (VAS) score, Wexner score and the American Society of Colon and Rectal Surgeons quality of life score were recorded at baseline and 6 months, along with an incontinence diary. Subjects underwent one weekly session for 12 consecutive weeks and then continued with six additional fortnightly sessions. An intention-to-treat analysis was performed.

RESULTS

Fifty-five patients (44 females; mean age 58.62 ± 10.74 years) with FI were treated with PTNS. The origins of the incontinence were obstetric (52.7 %) and perineal surgery (34.5 %). Eight patients did not continue with the second stage of treatment. The median Wexner baseline value was 9.98. After 6 months, it had decreased to 4.55 (p < 0.001). The visual analogue scale (VAS) increased from 4.94 to 6.80 (p < 0.001). There was a significant improvement in lifestyle, coping/behaviour, depression/self-perception and embarrassment scores. With respect to different types of FI, there was an improvement in the Wexner score both in patients with true passive FI and in those with urge or mixed FI.

CONCLUSIONS

PTNS is an effective treatment for FI. Patients with passive or urge FI can benefit from this therapy, with improvement of the Wexner score and quality of life variables.

How to Size the Anal Canal Circumference When Implanting a Magnetic Anal Sphincter for Fecal Incontinence. Evolution and Update of a New Surgical Technique

INTRODUCTION

Magnetic anal sphincter augmentation improves function and quality of life of patients with severe fecal incontinence substantially. Measuring the anal circumference exactly with a sizing tool represents a crucial step of the procedure because it determines the correct size and success of the definite implant.

OBJECTIVE

This study aims to illustrate the consequent development of 3 different sizing models and the use of the recent sizing tool.

TECHNIQUE

After dissection of a tunnel around the anal canal through a ventral perineal incision, the sizing tool is inserted by using a specially designed introducer to measure the circumference for the appropriate size of implant. First- and second-generation sizing tools could only approximate the final implant size and impeded standardization. The latest sizing model resembles the actual implant with magnetic beads, it is nonstretchable, and it is closable end-to-end.

RESULTS

The development of 3 measuring tools has progressively improved the accuracy of estimating the correct size of the definitive implant, and the application of the latest sizer seems easy, comfortable in use, and accurate as experienced in our first cases.

CONCLUSION

The latest device contributes to standardization of the procedure and therefore facilitates the learning curve for newcomers of the method and could avoid the need for radiological on-table control in the near future.

Values From Three-dimensional High-resolution Anorectal Manometry Analysis of Children Without Lower Gastrointestinal Symptoms

BACKGROUND & AIMS

Three-dimensional high-resolution anorectal manometry (3DHRAM) provides a topographic image of pressure along the anal canal. We aimed to determine normal 3DHRAM values in children.

METHODS

We performed a prospective study of 61 children (34 male; mean age, 8.28 years) without any symptoms arising from the lower gastrointestinal tract who were evaluated at the Department of Pediatric Gastroenterology and Nutrition, Medical University of Warsaw, Poland. Manometry procedures were performed by using a rigid probe without medication. Pressure within the anal canal and 3D images of sphincters were measured. If possible, squeeze pressure and thresholds of sensation were evaluated. The population was divided into age groups of <5 years, 5-8 years, 9-12 years, and older than 12 years.

RESULTS

The mean resting and squeeze sphincter pressures were 83 ± 23 mm Hg and 191 ± 64 mm Hg, respectively. The mean length of the anal canal was 2.62 ± 0.68 cm and correlated with age (r = 0.49, P < .0001). The mean rectal balloon volume to elicit rectoanal inhibitory reflex was 15.7 ± 10.9 cm(3). The first sensation, urge, and discomfort were observed at balloon volumes of 24.4 ± 23.98 cm(3), 45.9 ± 34.55 cm(3), and 91.6 ± 50.17 cm(3), respectively. The mean resting pressure of the puborectalis muscle was 69 ± 14 mm Hg, whereas the mean squeeze pressure was 124 ± 33 mm Hg. There was no statistically significant difference in pressure parameters between age groups. We observed a positive correlation between age and balloon volume needed to elicit discomfort (r = 0.49, P < .001).

CONCLUSIONS

In a prospective study, we determined normal values from 3DHRAM analysis of children without symptoms arising from the lower gastrointestinal tract. There were no significant differences in pressure results between children of different sexes or ages. ClinicalTrials.gov number: NCT02236507.

Challenges faced in the clinical application of artificial anal sphincters

Fecal incontinence is an unresolved problem, which has a serious effect on patients, both physically and psychologically. For patients with severe symptoms, treatment with an artificial anal sphincter could be a potential option to restore continence. Currently, the Acticon Neosphincter is the only device certified by the US Food and Drug Administration. In this paper, the clinical safety and efficacy of the Acticon Neosphincter are evaluated and discussed. Furthermore, some other key studies on artificial anal sphincters are presented and summarized. In particular, this paper highlights that the crucial problem in this technology is to maintain long-term biomechanical compatibility between implants and surrounding tissues. Compatibility is affected by changes in both the morphology and mechanical properties of the tissues surrounding the implants. A new approach for enhancing the long-term biomechanical compatibility of implantable artificial sphincters is proposed based on the use of smart materials.

Fecal Incontinence and Pelvic Floor Dysfunction in Women: A Review

Pelvic floor dysfunction and fecal incontinence is a common and debilitating condition in women, particularly as women age, and often goes under-reported to health care providers. It is important for providers to ask patients about possible symptoms. An algorithm for evaluation and treatment is presented. Current and future therapies are described and discussed.

Identifying factors associated with clinical success in patients treated with NASHA(®)/Dx injection for fecal incontinence

Purpose

Injection with the bulking agent consisting of non-animal stabilized hyaluronic acid/dextranomer (NASHA^®/Dx) is well tolerated and efficacious for the treatment of fecal incontinence (FI); however, the patient population that may derive maximum benefit has not been established. This post hoc responder analysis assessed demographic and baseline characteristics predictive of responsiveness to NASHA/Dx treatment.

Methods

Adults with a Cleveland Clinic Florida fecal incontinence score (CCFIS) ≥10 were randomized to receive NASHA/Dx or sham treatment. The primary end point was response to treatment (ie, decrease from baseline of ≥50% in number of FI episodes) at 6 months; a prespecified secondary end point was change in fecal incontinence quality of life (FIQL) score at 6 months. Post hoc subgroup analyses were performed for baseline and demographic characteristics and prior FI treatments.

Results

Overall, response to treatment was significantly greater with NASHA/Dx versus sham injection (52.7% vs 32.1%; P=0.0089). All subgroups analyzed demonstrated evidence of improvement, favoring NASHA/Dx versus sham treatment for both response to treatment and change in the FIQL coping/behavior subscale score. For the primary end point, a significantly greater percentage of patients with CCFIS ≤15, FI symptoms ≤5 years’ duration, or obstetric causes of FI responded to NASHA/Dx treatment versus patients receiving sham treatment (51.1% vs 28.3%, P=0.0169; 55.4% vs 25.7%, P=0.0026; and 53.6% vs 23.1%, P=0.0191, respectively). The mean change in the FIQL coping/behavior score significantly favored NASHA/Dx versus sham treatment for patients with CCFIS ≤15 (P=0.0371), FI symptoms ≤5 years’ duration (P=0.0289), or obstetric causes of FI (P=0.0384). Patients without a history of specific FI treatments (eg, antidiarrheal medications, biofeedback, surgery) were more likely to respond to NASHA/Dx versus sham treatment for both end points.

Conclusion

Although all subgroups analyzed showed evidence of quantitative and qualitative benefit from NASHA/Dx therapy, patients with characteristics indicative of mild-to-moderate FI may exhibit the greatest benefit.

Impact of fecal incontinence and its treatment on quality of life in women

Fecal incontinence (FI) is a physically and psychosocially debilitating disorder which negatively impacts quality of life (QOL). It bears a significant burden not only on patients but also on their families, caretakers as well as society as a whole. Even though it is considered a somewhat common condition, especially as women age, the prevalence is often underestimated due to patients' reluctance to report symptoms or seek care. The evaluation and treatment of FI can be also hindered by lack of understanding of the current management options among healthcare providers and how they impact on QOL. This article provides a comprehensive review on the impact of FI and its treatment on QOL in women.

Prevalence of faecal incontinence in the community: a cross-sectional study in Singapore

INTRODUCTION

Faecal incontinence (FI) is a stigmatised condition that remains a silent affliction for many populations. To date, no local study has been performed to determine its prevalence in our population. The existing literature from the West has shown highly variable rates, ranging from 0.8% to 18.0%. The aim of this study was to determine the cross-sectional prevalence of FI in Singapore and to identify at-risk groups.

METHODS

A door-to-door questionnaire survey was performed between February and March 2013. We randomly selected 1,000 individuals from the electoral roll to be surveyed using the validated Comprehensive Fecal Incontinence Questionnaire.

RESULTS

A total of 381 participants agreed to be enrolled in the study. The mean age of the participants was 52 (range 21-86) years, and slightly more than half of the participants were female (52.8%). Among the female participants, 73.1% had children (78.8% underwent normal vaginal delivery). The overall prevalence of FI in our study population was 4.7%. The prevalence of FI was observed to be significantly associated with increasing age (p = 0.004) and female gender (p = 0.029); women were three times more likely to suffer from FI than men.

CONCLUSION

With the ageing population of Singapore, the results of the present study provide further impetus to continue public outreach efforts as well as develop clinical programmes that address the growing need for specialist treatments for people with FI.

Efficacy and quality of life after transcutaneous posterior tibial neuromodulation for faecal incontinence

AIM

The aim of this study was to evaluate the efficacy of transcutaneous neuromodulation of the posterior tibial nerve for faecal incontinence and to assess quality of life after the procedure.

METHOD

A prospective non-randomized cohort study was conducted in a tertiary centre from September 2010 to May 2013. All patients with faecal incontinence who met the inclusion criteria were included and were treated as outpatients during a 3-month period by unilateral neuromodulation of the posterior tibial nerve. The patients were followed 3-monthly for 1 year. Severity scales, a bowel diary and quality of life scales were evaluated prospectively before and after treatment.

RESULTS

Twenty-seven patients of median age 67 (interquartile range 60-69) years and a male to female ratio of 1/6 were included. Faecal incontinence was for solid stools in 48.1% of patients with urgency in 55.6%. About one-third (34.6%) had a sphincter defect on ultrasound and reduction of anal canal pressure in 85.2%. There was a significant improvement in episodes of incontinence on the Wexner score and visual analogue scale assessment and a decrease in the number of episodes of incontinence per unit time. The Fecal Incontinence Quality of Life score was improved at the end of the follow-up. No adverse effects were observed. The cost of the treatment was €135 per patient.

CONCLUSION

Transcutaneous posterior tibial nerve neuromodulation provides good treatment for faecal incontinence in terms of efficacy and quality of life.

Diagnosis and treatment of faecal incontinence: Consensus statement of the Italian Society of Colorectal Surgery and the Italian Association of Hospital Gastroenterologists

Faecal incontinence is a common and disturbing condition, which leads to impaired quality of life and huge social and economic costs. Although recent studies have identified novel diagnostic modalities and therapeutic options, the best diagnostic and therapeutic approach is not yet completely known and shared among experts in this field. The Italian Society of Colorectal Surgery and the Italian Association of Hospital Gastroenterologists selected a pool of experts to constitute a joint committee on the basis of their experience in treating pelvic floor disorders. The aim was to develop a position paper on the diagnostic and therapeutic aspects of faecal incontinence, to provide practical recommendations for a cost-effective diagnostic work-up and a tailored treatment strategy. The recommendations were defined and graded on the basis of levels of evidence in accordance with the criteria of the Oxford Centre for Evidence-Based Medicine, and were based on currently published scientific evidence. Each statement was drafted through constant communication and evaluation conducted both online and during face-to-face working meetings. A brief recommendation at the end of each paragraph allows clinicians to find concise responses to each diagnostic and therapeutic issue.
