Anal sphincter imaging: better done at rest or on pelvic floor muscle contraction? Int Urogynecol J 2019; 31:1191-1196. [PMID: 31813034 DOI: 10.1007/s00192-019-04130-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2019] [Accepted: 09/16/2019] [Indexed: 12/31/2022]
Abstract
INTRODUCTION AND HYPOTHESIS Exo-anal ultrasound imaging of the anal sphincter is usually undertaken on pelvic floor muscle contraction (PFMC) as this seems to enhance tissue discrimination. Some women are unable to achieve a satisfactory PFMC, and in this situation, the sphincter is assessed at rest. We aimed to determine whether sphincter imaging at rest is inferior to imaging on PFMC. METHODS We analysed 441 women in this retrospective study. All underwent a standardised interview, including St Mark's incontinence score, clinical examination and 4D trans-labial ultrasound (TLUS). On analysing volume data, tomographic imaging was used to obtain a standardised set of slices at rest and on PFMC to evaluate external anal sphincter (EAS) and internal anal sphincter (IAS) trauma as described previously. RESULTS When assessments obtained from volumes acquired at rest and on PFMC were tested against measures of anal incontinence (AI), all associations between the diagnosis of significant anal sphincter defects and AI were no stronger when imaging was performed on PFMC. On cross-tabulation, the percentage agreement for significant defects of the EAS and IAS at rest and on PFMC was 96.5% and 98.9% respectively, if discrepancy by one slice was allowed. CONCLUSIONS Exo-anal tomographic imaging of sphincter defects at rest seems sufficiently valid for clinical use and may not be inferior to sphincter assessment on pelvic floor muscle contraction.

Abstract
BACKGROUND Eighty per cent of care home residents in the UK are living with dementia. The prevalence of faecal incontinence (FI) in care homes is estimated to range from 30% to 50%. There is limited evidence of what is effective in the reduction and management of FI in care homes. OBJECTIVE To provide a theory-driven explanation of the effectiveness of programmes that aim to improve FI in people with advanced dementia in care homes. DESIGN A realist synthesis. This was an iterative approach that involved scoping of the literature and consultation with five stakeholder groups, a systematic search and analysis of published and unpublished evidence, and a validation of programme theories with relevant stakeholders. DATA SOURCES The databases searched included PubMed, Cumulative Index to Nursing and Allied Health Literature, The Cochrane Library, Scopus, SocAbs, Applied Social Sciences Index and Abstracts, BiblioMap, Sirius, OpenGrey, Social Care Online and the National Research Register. RESULTS The scoping identified six programme theories with related context-mechanism-outcome configurations for testing. These addressed (1) clinician-led support, assessment and review, (2) the contribution of teaching and support for care home staff on how to reduce and manage FI, (3) the causes and prevention of constipation, (4) how the cognitive and physical capacity of the resident affect outcomes, (5) how the potential for recovery, reduction and management of FI is understood by those involved and (6) how the care of people living with dementia and FI is integral to the work patterns of the care home and its staff. Data extraction was completed on 62 core papers with iterative searches of linked literature. Dementia was a known risk factor for FI, but its affect on the uptake of different interventions and the dementia-specific continence and toileting skills staff required was not addressed. Most care home residents with FI will be doubly incontinent and, therefore, there is limited value in focusing solely on FI or on single causes of FI such as constipation. Clinical assessment, knowledge of the causes of FI and strategies that recognise the individuals' preferences are necessary contextual factors. Valuing the intimate and personal care work that care home staff provide to people living with dementia and addressing the dementia-related challenges when providing continence care within the daily work routines are key to helping to reduce and manage FI in this population. LIMITATIONS The synthesis was constrained by limited evidence specific to FI and people with dementia in care homes and by the lack of dementia-specific evidence on continence aids. CONCLUSIONS This realist synthesis provides a theory-driven understanding of the conditions under which improvement in care for care home residents living with dementia and FI is likely to be successful. FUTURE WORK Future multicomponent interventions need to take account of how the presence of dementia affects the behaviours and choices of those delivering and receiving continence care within a care home environment.

Abstract
BACKGROUND Regenerating muscle at a time remote from injury requires re-expression of cytokines to attract stem cells to start and sustain the process of repair. OBJECTIVE We aimed to evaluate the sustainability of muscle regeneration after treatment with a nonviral plasmid expressing stromal cell-derived factor 1. DESIGN This was a randomized study. SETTINGS The study was conducted with animals in a single research facility. INTERVENTIONS Fifty-six female age-/weight-matched Sprague-Dawley rats underwent excision of the ventral half of the anal sphincter complex. Three weeks later, rats were randomly allocated (n = 8) to one of the following groups: no treatment, 100 μg of plasmid encoding stromal cell-derived factor 1 injected locally, local injection of plasmid and 8 × 10 bone marrow-derived mesenchymal stem cells, and plasmid encoding stromal cell-derived factor 1 injected locally with injection of a gelatin scaffold mixed with bone marrow-derived mesenchymal stem cells. MAIN OUTCOME MEASURES Anal manometry, histology, immunohistochemistrym and morphometry were performed 8 weeks after treatment. Protein expression of cytokines CXCR4 and Myf5 was investigated 1 week after treatment (n = 6 per group). ANOVA was used, with p < 0.0083 indicating significant differences for anal manometry and p < 0.05 for all other statistical analysis. RESULTS Eight weeks after treatment, all of the groups receiving the plasmid had significantly higher anal pressures than controls and more organized muscle architecture in the region of the defect. Animals receiving plasmid alone had significantly greater muscle in the defect (p = 0.03) than either animals with injury alone (p = 0.02) or those receiving the plasmid, cells, and scaffold (p = 0.03). Both smooth and skeletal muscles were regenerated significantly more after plasmid treatment. There were no significant differences in the protein levels of CXCR4 or Myf5. LIMITATIONS The study was limited by its small sample size and because stromal cell-derived factor 1 was not blocked. CONCLUSIONS A plasmid expressing stromal cell-derived factor 1 may be sufficient to repair an injured anal sphincter even long after the injury and in the absence of mesenchymal stem cell or scaffold treatments.

Abstract
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.

Abstract
INTRODUCTION AND HYPOTHESIS Jorge and Wexner devised a questionnaire for anal incontinence (AI), known as the Wexner scale (WS). Specific validated questionnaires are essential for the assessment of symptom severity. The objective was to accomplish the cultural adaptation and validation of the Portuguese version of the WS. METHODS The WS was validated according to the international criteria. A Brazilian version was tested, including the item "I do not understand" at the end of each question. If this answer was reported at a rate higher than 15 %, the item would be considered difficult to understand and would thus be modified. The final version of the WS and the Fecal Incontinence Quality of Life (FIQL) were completed by 50 women. Convergent validity was assessed by comparing the data from the first interview of the WS with the FIQL using Spearman's test. Reproducibility was assessed by means of a 2-week test-retest procedure using Cronbach's alpha coefficient. RESULTS In the initial version of the questionnaire, we did not obtain a response of "I do not understand" at a rate greater than 15 % and this version was considered definitive. A significant negative relationship (r = -0.63) was found between the FIQL total score and the WS. The answers obtained on the "test-re-est" questionnaires showed a significant correlation according to the intraclass correlation coefficient (ICC). A high level of internal consistency was found, as demonstrated by a Cronbach's alpha of 0.932. CONCLUSION The Brazilian Portuguese version of the WS is a reliable, consistent, and valid instrument.

Abstract
Bulking agent injected submucosally is an alternative effective treatment for faecal incontinence in elderly patients who fail conservative measures. Since most elderly patients are on antiplatelet therapy and are sometimes unaware of their medication, this can lead to serious complications.

Abstract
Fecal incontinence (FI) is a devastating condition affecting a substantial portion of the population. The etiologies of FI are wide ranging, as are the treatment options. When conservative measures fail, often surgical intervention is required. As in any area where a wide range of treatment options exist, there is no one perfect solution. Fortunately, novel treatment options for FI are becoming available, namely, posterior tibial nerve stimulation, magnetic anal sphincter, stem cell transplant, pyloric transplantation, and acupuncture.

Abstract
PURPOSE OF REVIEW Fecal incontinence is a significant source of morbidity and decreased quality of life (QOL) for many. Until recent years, few therapies beyond medical management were available for patients. Surgical treatment of fecal incontinence has evolved from colostomy and direct repair of muscle defects to interventional techniques such as nerve stimulation and bulking agents. We review the most recent surgical options for the treatment of fecal incontinence within the context of established therapies. RECENT FINDINGS Overlapping sphincteroplasty is an established therapy that improves continence and QOL, although results deteriorate over time. Implanted artificial bowel sphincter has a 100% complication rate and 80% are explanted over time. Sacral nerve stimulation has minimal risk and more durable long-term improvement in continence. Less invasive versions of nerve stimulation are being researched. Injectable biomaterials have shown some promise, although durability of results is not clear. Novel therapies, including muscle cell transfer and pelvic slings are currently being investigated. SUMMARY Surgical therapies for fecal incontinence continue to evolve and show promise in improving QOL with a lower risk profile. Effective valuation of these therapies is currently limited by heterogeneous studies, short duration of follow up, and inconsistent outcome measures.

Abstract
BACKGROUND AND AIMS No previous study has reported on faecal incontinence (FI) amongst people with IBD. We aimed to determine the frequency and severity of FI in people with IBD, its association with known FI risk factors, and the effect on quality of life. METHOD We randomly sampled 10,000 members of a national Crohn's and Colitis organisation over 18years old. Demographic information, medical history, FI (ICIQ-B), urinary continence (ICIQ-UI), quality of life (IBD-Q) and free text responses about FI were collected. Current disease activity was reported using the Harvey Bradshaw Index for Crohn's Disease (CD), and the Walmsley Index for ulcerative colitis (UC). Data were managed using Excel, Stata and SPSS 18. RESULTS 4827 responses were received: 3264 were complete and included (32.6% response). 2178 respondents were female (66.7%); mean age 50.26 yrs (range 19-92); CD 1543 (46.98%); UC 1599 (48.97%); other IBD 126 (3.85%); no diagnosis given 6 (0.18%). 74% (2391) of respondents reported FI (95% CI 72-75). Nine percent (299) reported regular FI. No association was found between FI and diagnosis. Significant associations were found in multivariable analysis between FI and age (p=0.005), gender (p<0.001), anal stretch (p=0.004), anal fistula surgery (p<0.001), colo-rectal surgery (p=<0.001), and urinary incontinence (p=<0.001), but not with vaginal delivery. Quality of life was significantly affected by FI (p<0.001). CONCLUSION Even if all non-respondents are continent, FI affects 24% of people with IBD. In our sample 74% reported FI, which can occur without active disease. There is a large currently unmet need for continence care in people with IBD.

Abstract
We propose pretreatment using microneedles to increase perianal skin permeability for locally targeted delivery of phenylephrine (PE), a drug that increases resting anal sphincter pressure to treat fecal incontinence. Microneedle patches were fabricated by micromolding poly-lactic-acid. Pre-treatment of human cadaver skin with microneedles increased PE delivery across the skin by up to 10-fold in vitro. In vivo delivery was assessed in rats receiving treatment with or without use of microneedles and with or without PE. Resting anal sphincter pressure was then measured over time using water-perfused anorectal manometry. For rats pretreated with microneedles, topical application of 30% PE gel rapidly increased the mean resting anal sphincter pressure from 7±2 cm H(2)O to a peak value of 43±17 cm H(2)O after 1 h, which was significantly greater than rats receiving PE gel without microneedle pretreatment. Additional safety studies showed that topically applied green fluorescent protein-expressing E. coli penetrated skin pierced with 23- and 26-gauge hypodermic needles, but E. coli was not detected in skin pretreated with microneedles, which suggests that microneedle-treated skin may not be especially susceptible to infection. In conclusion, this study demonstrates local transdermal delivery of PE to the anal sphincter muscle using microneedles, which may provide a novel treatment for fecal incontinence.

Abstract
Faecal incontinence is a common multifactorial condition with a range of invasive treatment options, all of which may be associated with significant complications. Posterior tibial stimulation by continence nurses is an established treatment for urinary incontinence; however, its use in faecal incontinence, while rapidly evolving, is limited to eight small and differing studies. In this article, the background of current management options for faecal incontinence is discussed, as are the physiology and evidence underlying neuromodulation. The evidence base for posterior tibial nerve stimulation in faecal incontinence is reviewed, as well as the implications for practice and further research. While this early evidence base is encouraging, it has yet to be established whether this novel approach may be the minimally invasive, effective and cheap treatment hoped for, for this common and debilitating condition.

Abstract
INTRODUCTION Faecal incontinence is a prevalent and important condition, with a range of treatment options. Neuromodulation via sacral nerve stimulators is efficacious, but expensive and associated with complications due to device implantation. Peripheral neuromodulation via posterior tibial nerve stimulation (PTNS) has been assessed in urinary incontinence, but there is minimal evidence for its use in faecal incontinence and no literature from the UK. This retrospective review aimed to assess the efficacy of PTNS in faecal incontinence. PATIENTS AND METHODS Thirteen consecutive female patients with faecal incontinence of various causes (9 idiopathic, 3 obstetric, 1 surgery) underwent PTNS at a UK hospital. All were investigated with colonic imaging, anorectal physiology and endo-anal ultrasound. Prior treatments included physiotherapy (13), sphincteroplasty (3) biofeedback (3) and PTQ implants (1). PTNS was performed for 30 min, weekly for 12 weeks. RESULTS Median monthly episodes of incontinence of wind, liquid and solid reduced from 6, 10 and 18 respectively to 0 with 12 weeks' treatment (P < 0.05). Significant improvements in quality of life indices were also seen. At 1-month follow up, a sustained reduction in incontinence of wind was seen (0 episodes), with non-significant reductions of liquid and solid stool. CONCLUSIONS PTNS is a potentially efficacious, technically simple and minimally invasive alternative treatment modality for faecal incontinence. These early results are encouraging, but we await medium- and long-term follow-up, and a larger randomised trial comparing PTNS with alternative treatments and placebo.

Abstract
Faecal incontinence is a high prevalence disease in the general population. This pathology is commonly under-estimated and causes a great impact on clinical status and on the quality of life of affected patients. The prevalence of faecal incontinence in several studies has been estimated between 2% and 15% of the general population. The prevalence increases if we study selected populations, such as elderly people. The main cause of faecal incontinence is obstetric anal sphincter damage. In the past years, the presence of incontinence due to sphincter lesions, especially the obstetric ones, was an absolute indication of anterior anal sphincter repair. Actually, after knowing the long term follow up results of this technique, as well as the evolving knowledge on faecal incontinence and the development of new diagnostic and therapeutic techniques, this technique might be selected for cases with large sphincter defects. However there is limited information in the current literature on indications, surgical technique and results of anterior sphincter repair. The aim of this review is to analyse scientific evidence on current indications, surgical technique features and results of anterior sphincter repair as a therapy for faecal incontinence, also giving our point of view on controversial issues. A bibliography search was undertaken using Medline database including articles published from January 1985 to January 2009.

Abstract
Fecal incontinence is a devastating underestimated problem, affecting a large number of individuals all over the world. Most of the available literature relates to the management of adults. The treatments proposed are not uniformly successful and have little application in the pediatric population. This paper presents the experience of 30 years, implementing a bowel management program, for the treatment of fecal incontinence in over 700 pediatric patients, with a success rate of 95%. The main characteristics of the program include the identification of the characteristics of the colon of each patient; finding the specific type of enema that will clean that colon and the radiological monitoring of the process.

Abstract
Present studies determined the roles of the cyclooxygenase (COX) versus the lipoxygenase (LO) pathways in the metabolic pathway of arachidonic acid (AA) in the internal anal sphincter (IAS) tone. Studies were performed in the rat IAS versus the nontonic rectal smooth muscle (RSM). Indomethacin, the dual COX inhibitor, but not nordihydroguaiaretic acid (NDGA), the LO inhibitor, produced a precipitous decrease in the IAS tone. However, when added in the background of indomethacin, NDGA caused significant reversal of the IAS tone. These inhibitors had no significant effect on the RSM. To follow the significance of COX versus LO pathways, we examined the effects of AA and its metabolites. In the IAS, AA caused an increase in the IAS tone (Emax=38.8+/-3.0% and pEC50=3.4+/-0.1). In the RSM, AA was significantly less efficacious and potent (Emax=11.3+/-3.5% and pEC50=2.2+/-0.3). The AA metabolites (via COXs) PGF2alpha and U-46619 (a stable analog of thromboxane A2) produced increases in the IAS tone and force in the RSM. Conversely, AA metabolites (via 5-LO) lipoxin A4, 5-HETE, and leukotriene C4 decreased the IAS tone. Finally, the contractile effects of AA in the IAS were selectively attenuated by the COX-1 but not the COX-2 inhibitor. Collectively, the specific effects of AA and the COX inhibitor, the Western blot and RT-PCR analyses showing specifically higher levels of COX-1, suggest a preferential role of the COX (specifically COX-1) pathway versus the LO in the regulation of the IAS tone.
