Abstract
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).

Abstract
BACKGROUND Accurate measurement of anal sphincter function is potentially of value in defining treatment of common pelvic floor disorders. The aim of this study was to establish repeatability and validate high-resolution anorectal manometry (HRAM) by comparison to conventional manometry (CM). Arising from this work would be definitive normal range data. METHODS Eighty healthy volunteers (40 female) underwent a test-retest repeatability study. A 16-channel water-perfused HRAM catheter was compared to an 8-channel conventional catheter using a station pull-through technique. KEY RESULTS High-resolution anorectal manometry had similar precision to conventional manometry when measuring resting pressure (intraclass correlation coefficient [ICC] 0.73 vs 0.68, HRAM vs CM) and squeeze increment (ICC 0.90 vs 0.94, HRAM vs CM). HRAM measured resting pressures 10% lower than CM and squeeze pressure 27% higher than CM. CONCLUSIONS AND INFERENCES High-resolution anorectal manometry is a valid technique with comparable precision to CM. HRAM measurements differ considerably to CM, and a new set of normal values must be used.

Abstract
Introduction: Fecal incontinence refers to the inability to control bowel movements, causing feces to leak unexpectedly from the rectum. People suffering from this disorder are emotionally distressed. This problem causes social degradation, anxiety, fear, and social isolation. The present study aimed to evaluate the effect of biofeedback (BFB) on fecal incontinence in patients with anal sphincter abnormalities in 2017. Methods: This quasi-experimental study was performed on 30 patients with fecal incontinence, referring to the gastroenterology clinic of Taleghani and Mehrad hospitals. Patients were first evaluated by Wexner criteria and then, with the aid of a manometer, information was obtained on the amount of sphincter muscle tone, squeeze pressure, and rectal sensation. Manometric results and Waxner's questionnaire were compared before and after BFB. Data were analyzed using SPSS (version 20). Findings: In this study, 18 women and 12 men were studied. There was no significant relationship between fluid intake, fiber, exercise, sex, and incontinence (P < 0.05). According to Wuxner's components, the sphincter muscle tone increased significantly after BFB in patients. The total score of the squeeze pressure increased significantly after the BFB application (P < 0.05). The mean total score of rectal sensation (individual awareness of rectal contents) decreased after the BFB application. Conclusion: In addition to the fact that it can improve incontinence in patients with anal sphincter abnormalities, BFB is also helpful for patients whose sphincter and rectum are not seriously affected and only show incontinence symptoms.

Effect of age, patient's sex, and type of trauma on the correlation between size of sphincter defect and anal pressures in posttraumatic fecal incontinence. Surgery 2016; 160:1318-1325. [PMID: 27392390 DOI: 10.1016/j.surg.2016.05.020] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2016] [Revised: 05/15/2016] [Accepted: 05/19/2016] [Indexed: 01/28/2023]
Abstract
BACKGROUND The physiologic assessment of anal sphincters in cases of posttraumatic fecal incontinence is a fundamental step in planning operative treatment. In this study, we evaluate the correlation between size of anal sphincter defect, anal pressures, and clinical symptoms in patients with posttraumatic fecal incontinence. We also investigate the impact of patients' age, sex, and type of trauma on this correlation. METHODS Records of 70 patients fitting the study's eligibility criteria were collected retrospectively from the archives of Mansoura University Hospitals' colorectal surgery unit. Demographic data of patients, causes of fecal incontinence, images of sphincter defects on endorectal ultrasonography, anal resting and squeeze pressures, and Wexner continence scores were collected, and correlation analysis was performed. RESULTS Seventy patients (54 males and 16 females) with a mean (±standard deviation) age of 36 ± 16 years were studied. Mean maximal resting anal pressure was 42 ± 16 mm Hg, and mean maximal squeeze anal pressure was 80 ± 35 mm Hg. Size of external anal sphincter defect was negatively correlated with mean maximal squeeze (r = -0.4298). Mean Wexner continence score was correlated positively with size of external anal sphincter defect (r = 0.3743). Both correlations became significantly stronger in female patients, patients greater than 50 years, postfistulectomy patients, and patients with obstetric injuries. CONCLUSION Size of external anal sphincter defect correlates negatively with mean maximal squeeze and positively with symptoms score. This correlation is stronger in females, patients greater than 50 years, and patients with postfistulectomy or obstetric injuries. These findings suggest that this group of patients requires additional assessment before surgical repair.

Abstract
Fecal incontinence (FI) is a debilitating disorder which negatively impacts quality of life. The etiology is often multifactorial and although most women with FI are able to be treated, many remain untreated because a significant proportion of women do not report their symptoms and seek care. The evaluation and treatment of FI can be also hindered by a lack of understanding of the mechanisms and current options. This article provides a review on the evidence-based evaluation and management for FI.

Abstract
BACKGROUND Faecal incontinence is a debilitating problem with significant medical, social and economic implications. Treatment options include conservative, non-operative interventions (for example pelvic floor muscle training, biofeedback, drugs) and surgical procedures. A surgical procedure may be aimed at correcting an obvious mechanical defect, or augmenting a functionally deficient but structurally intact sphincter complex. OBJECTIVES To assess the effects of surgical techniques for the treatment of faecal incontinence in adults who do not have rectal prolapse. Our aim was firstly to compare surgical management with non-surgical management and secondly, to compare the various surgical techniques. SEARCH METHODS Electronic searches of the Cochrane Incontinence Group Specialised Register (searched 6 March 2013), the Cochrane Colorectal Cancer Group Specialised Register (searched 6 March 2013), CENTRAL (2013, issue 1) and EMBASE (1 January 1998 to 6 March 2013) were undertaken. The British Journal of Surgery (1 January 1995 to 6 March 2013), Colorectal Diseases (1 January 2000 to 6 March 2013) and the Diseases of the Colon and Rectum (1 January 1995 to 6 March 2013) were specifically handsearched. The proceedings of the Association of Coloproctology of Great Britain and Ireland annual meetings held from 1999 to 2012 were perused. Reference lists of all relevant articles were searched for further trials. SELECTION CRITERIA All randomised or quasi-randomised trials of surgery in the management of adult faecal incontinence (other than surgery for rectal prolapse). DATA COLLECTION AND ANALYSIS Three review authors independently selected studies from the literature, assessed the methodological quality of eligible trials and extracted data. The three primary outcome measures were change or deterioration in incontinence, failure to achieve full continence, and the presence of faecal urgency. MAIN RESULTS Nine trials were included with a total sample size of 264 participants. Two trials included a group managed non-surgically. One trial compared levatorplasty with anal plug electrostimulation and one compared an artificial bowel sphincter with best supportive care. The artificial bowel sphincter resulted in significant improvements in at least one primary outcome but the numbers were small. The other trial showed no difference in the primary outcome measures.Seven trials compared different surgical interventions. These included anterior levatorplasty versus postanal repair, anterior levatorplasty versus total pelvic floor repair, total pelvic floor versus postanal repair, end to end versus overlap sphincter repair, overlap repair with or without a defunctioning stoma or with or without biofeedback, and total pelvic floor repair versus repair plus internal sphincter plication and neosphincter formation versus total pelvic floor repair. Sacral nerve stimulation and injectables are considered in separate Cochrane reviews. Only one comparison had more than one trial (total pelvic floor versus postanal repair, 44 participants) and no trial showed any difference in primary outcome measures. AUTHORS' CONCLUSIONS The review is striking for the lack of high quality randomised controlled trials on faecal incontinence surgery that have been carried out in the last 10 years. Those trials that have been carried out have focused on sacral neuromodulation and injectable bulking agents, both reported in separate reviews. The continued small number of relevant trials identified together with their small sample sizes and other methodological weaknesses limit the usefulness of this review for guiding practice. It was impossible to identify or refute clinically important differences between the alternative surgical procedures. Larger rigorous trials are still needed. However, it should be recognised that the optimal treatment regime may be a complex combination of various surgical and non-surgical therapies.

Abstract
PURPOSE Assessment of anal sphincter tone is a critical part of anorectal examination, yet no standardized, quantifiable method for describing anal sphincter tone on digital rectal examination exists. We developed a novel scoring system for anal sphincter tone using a scale of 0 to 5 for both resting pressure and squeeze pressure. The score ranges from 0 = no discernable pressure to 5 = extremely tight and 3 = normal. We hypothesized that the digital rectal examination scoring system (DRESS) score would correlate with anorectal manometry pressures. METHODS Three hundred three patients (mean age, 51 y; range, 28-86 y) who had a DRESS score and a concurrent manometry test (1998-2008) were identified from a prospective database. Means of 4 quadrant manometry at rest and with squeeze were compared with the resting pressure and squeeze pressure DRESS scores at each point from 0 to 5. Box plots for manometry results by DRESS score were graphed. ANOVA using a significance level of α = .05 tested whether each of the DRESS scores were different from one another. Spearman rank correlation coefficients assessed associations between manometry and DRESS results. RESULTS Manometric pressures (mmHg; mean ± SEM) for DRESS resting pressure values 0 to 5 were 20.6 ± 2.1, 38.5 ± 2.0, 47.8 ± 1.6, 72.3 ± 1.5, 94.4 ± 2.9, and 128.0 ± 6.7, respectively. Pressures for DRESS squeeze pressure values 0 to 5 were 45.9 ± 5.6, 66.5 ± 3.2, 108.2 ± 4.9, 156.3 ± 4.5, 238.6 ± 9.8, and 368.2 ± 49.1. Box plots demonstrated clear differences between each DRESS score and positive progression from 0 to 5 for both resting pressure and squeeze pressure. ANOVA analysis showed a significant difference in mean manometry measurements at all levels of digital rectal examination, both for resting pressure and squeeze pressure (P < .001). Spearman rank correlations showed a strong positive correlation between the DRESS values and manometry pressures with coefficients of 0.82 for resting pressure and 0.81 for squeeze pressure. CONCLUSIONS The DRESS score correlated very well with manometry pressures for resting pressure and squeeze pressure. The DRESS system may be a useful description of anal sphincter resting pressure and squeeze pressure in the clinical setting. Further validation may support adoption of the DRESS system as part of the standard anorectal examination.

Abstract
Anal incontinence is a symptom represented by the impaired ability to control the elimination of gas and stool, with an estimated incidence of 2.2 to 7.1% of the population. These numbers likely under-represent the true prevalence because physicians and patients are reluctant to discuss this problem. Evaluation of the patient with anal incontinence requires a fundamental knowledge of the etiologic factors. Careful history and physical examination is essential in every patient and can identify the cause of most cases of incontinence. Incontinence scoring systems are tools that provide objective data regarding the severity and quality of anal incontinence. Supplemental special tests for evaluating incontinence should be aimed at achieving three goals: (1) provide additional and confirmatory information regarding the diagnosis and cause of incontinence; (2) select appropriate treatment; and (3) predict treatment outcome. Numerous studies to evaluate anal incontinence exist; however, the most useful tests to achieve these goals are anal manometry, pudendal nerve terminal motor latency, and anal endosonography, because these studies can identify physiologic, neurologic, and anatomic abnormalities of the anorectum for which there may be effective treatments.

Abstract
With advances in diagnostic technology, it is now accepted that in the field of functional bowel disorders, symptom-based assessment is unsatisfactory as the sole means of directing therapy. A robust taxonomy based on underlying pathophysiology has been suggested, highlighting a crucial role for physiologic testing in clinical practice. A wide number of complementary investigations currently exist for the assessment of anorectal structure and function, some of which have a clinical impact in patients with functional disorders of evacuation and continence by markedly improving diagnostic yield and altering management. The techniques, limitations, measurements, and clinical use of manometric, sensorimotor, and neurophysiologic tests of anorectal function are presented.

Abstract
INTRODUCTION We describe the relationship between anorectal manometry, fecal incontinence severity, and findings at endoanal ultrasound. METHODS A total of 351 women completed the Fecal Incontinence Severity Index, underwent anorectal manometry, and endoanal ultrasound. Severity index and manometry pressures in 203 women with intact sphincters on ultrasound were compared with pressures in 148 women with sphincter defects. Relationships between resting and squeeze pressures, severity index, and size of sphincter defects were evaluated. RESULTS Mean severity index in patients with and without sphincter defect was 35.7 vs. 36.7 (not significant). Worsening index correlated with worsening mean and maximum resting pressure (P < 0.0001). Differences were observed in mean and maximum resting pressure between the patients with and without sphincter defects (26.6 vs. 37.2, P < 0.0001; 39.4 vs. 51.7, P < 0.001). Resting pressures correlated with the sizes of defect (P < 0.0001). CONCLUSIONS Patients with and without sphincter defects had similar severity scores, but patients with defects had a significant decrease in resting pressures. Patients with larger sphincter defects had lower severity scores and resting pressures. Until a manometry cutoff can be set to discriminate between absence and presence of defects, both manometry and ultrasound should be offered to patients with history of anal trauma.

Abstract
AIM: To determine the indicated referrals to a tertiary centre for patients with anorectal symptoms, the effect of the advised treatment and the discomfort of the tests.
METHODS: In a retrospective study, patients referred for anorectal function evaluation (AFE) between May 2004 and October 2006 were sent a questionnaire, as were the doctors who referred them. AFE consisted of anal manometry, rectal compliance measurement and anal endosonography. An indicated referral was defined as needing AFE to establish a diagnosis with clinical consequence (fecal incontinence without diarrhea, 3rd degree anal sphincter rupture, congenital anorectal disorder, inflammatory bowel disease with anorectal complaints and preoperative in patients for re-anastomosis or enterostoma, anal fissure, fistula or constipation). Anal ultrasound is always indicated in patients with fistula, anal manometry and rectal compliance when impaired continence reserve is suspected. The therapeutic effect was noted as improvement, no improvement but reassurance, and deterioration.
RESULTS: From the 216 patients referred, 167 (78%) returned the questionnaire. The referrals were indicated in 65%. Of these, 80% followed the proposed advice. Improvement was achieved in 35% and a reassurance in 57% of the patients, no difference existed between patient groups. On a VAS scale (1 to 10) symptoms improved from 4.0 to 7.2. Most patients reported no or little discomfort with AFE.
CONCLUSION: Referral for AFE was indicated in 65%. Beneficial effect was seen in 92%: 35% improved and 57% was reassured. Advice was followed in 80%. Better instruction about indication for AFE referral is warranted.

Abstract
Fecal incontinence (FI) is defined as the involuntary passage of fecal material through the anal canal. True incontinence must be differentiated from pseudo incontinence. FI is predominately a disease of the elderly or of institutional patients. Fecal incontinence in the nursing home population has been estimated at 47%. We provide a guide to appropriate clinical evaluation, diagnostic testing, and treatment of FI.

Abstract
AIM This study aimed to develop and evaluate a scoring system for anal endosonography to assess anal canal structures after repair of anorectal malformations (ARM). METHODS Forty patients with ARM aged 16 years (range, 1-22 years) and 20 controls aged 17 years (range, 0.5-20 years) were examined. Anal function was assessed clinically and by anal canal manometry. The anal canal structures were imaged by anal endosonography using a 7.5-MHz transducer. A scoring system was developed to assess the anal sphincters as visualized on the endosonographic images. RESULTS Continence was significantly correlated to anal canal pressures. The estimated extent of muscle defect (measured in quadrants) and the number of disruptions in the internal and external anal sphincters correlated significantly to the rest and squeeze pressures, respectively. Thus, patients (>4 years) with squeeze pressure of less than 80 cm H2O were characterized by more than 1 disruption in the external anal sphincter ring and 2 or more quadrants with scar tissue. CONCLUSION The extent of scar tissue and the number of disruptions in the anal sphincters correlate with anal canal pressures and continence after ARM repair. Anal endosonography may be used to study the results after different surgical techniques and for prognosis on continence in patients with ARM.

Abstract
BACKGROUND Anal inspection and digital rectal examination are routinely performed in fecal incontinent patients but it is not clear to what extent they contribute to the diagnostic work-up. We examined if and how findings of anal inspection and rectal examination are associated with anorectal function tests and endoanal ultrasonography. METHODS A cohort of fecal incontinent patients (n=312, 90% females; mean age 59) prospectively underwent anal inspection and rectal examination. Findings were compared with results of anorectal function tests and endoanal ultrasonography. RESULTS Absent, decreased and normal resting and squeeze pressures at rectal examination correlated to some extent with mean (+/-SD) manometric findings: mean resting pressure 41.3 (+/-20), 43.8 (+/-20) and 61.6 (+/-23) Hg (p<0.001); incremental squeeze pressure 20.6 (+/-20), 38.4 (+/-31) and 62.4 (+/-34) Hg (p<0.001). External anal sphincter defects at rectal examination were confirmed with endoanal ultrasonography for defects <90 degrees in 36% (37/103); for defects between 90-150 degrees in 61% (20/33); for defects between 150-270 degrees in 100% (6/6). Patients with anal scar tissue at anal inspection had lower incremental squeeze pressures (p=0.04); patients with a gaping anus had lower resting pressures (p=0.013) at anorectal manometry. All other findings were not related to any anorectal function test or endoanal ultrasonography. CONCLUSIONS Anal inspection and digital rectal examination can give accurate information about internal and external anal sphincter function but are inaccurate for determining external anal sphincter defects <90 degrees. Therefore, a sufficient diagnostic work-up should comprise at least rectal examination, anal inspection and endoanal ultrasonography.

Abstract
BACKGROUND Faecal incontinence is a debilitating problem with significant medical, social and economic implications. Treatment options include conservative, non-surgical interventions (e.g. pelvic floor muscle training, biofeedback, drugs, sacral nerve stimulation) and surgical procedures. A surgical procedure may be aimed at correcting an obvious mechanical defect, or augmenting a functionally deficient but structurally intact sphincter complex or replace an absent/non-functioning sphincter. OBJECTIVES To assess the effects of surgical techniques for the treatment of faecal incontinence in adults who do not have rectal prolapse. Our aim was firstly to compare surgical management with non-surgical management and secondly, to compare the various surgical techniques. SEARCH STRATEGY We searched the Cochrane Incontinence Group Specialised Trials Register (31 January 2006), the Cochrane Colorectal Cancer Group trials register (31 January 2006), the Cochrane Central Register of Controlled Trials (2006, Issue 1), PubMed (1 January 1950 to 31 January 2006) and EMBASE (1 January 1998 to 31 January 2006) were undertaken. The British Journal of Surgery (January 1995 to May 2006) Colorectal Diseases (January 2000-May 2006) and the Diseases of the Colon and Rectum (January 1995 to May 2006) were specifically handsearched. The proceedings of the Association of Coloproctology meeting held from 1999 to 2006 were perused. Reference lists of all relevant articles were searched for further trials. SELECTION CRITERIA All randomised or quasi-randomised trials of surgery in the management of adult faecal incontinence (other than surgery for rectal prolapse). DATA COLLECTION AND ANALYSIS Two reviewers independently selected studies from the literature searches, assessed the methodological quality of eligible trials and extracted data. The three primary outcome measures were: change or deterioration in incontinence, failure to achieve full continence, and the presence of faecal urgency. MAIN RESULTS Nine trials were included with a total sample size of 264 participants. Two trials included a group managed non-surgically. One trial compared levatorplasty with anal plug stimulation, one compared artificial bowel sphincter with best supportive care; numbers were small in both trials. The artificial bowel sphincter insertion was followed by significant improvements in at least one primary outcome but with high rates of significant morbidity. Seven studies compared different surgical interventions. These included anterior levatorplasty versus postanal repair, anterior levatorplasty versus total pelvic floor repair, total pelvic floor versus postanal repair, end to end versus overlap sphincter repair, overlap repair with or without a defunctioning stoma or with or without biofeedback, total pelvic floor repair versus repair plus internal sphincter plication and neosphincter formation versus total pelvic floor repair. Only one comparison had more that one trial (total pelvic floor versus postanal repair-44 participants) and no comparison showed any statistically significant difference in primary outcome measures, with wide confidence intervals. AUTHORS' CONCLUSIONS Despite more studies being included in this update, the continued small number of relevant trials identified together with their small sample sizes and other methodological weaknesses continue to limit the usefulness of this review for guiding practice. It was impossible to identify or refute clinically important differences between the alternative surgical procedures. Larger rigorous trials are still needed. However, it should be recognised that the optimal treatment regime may be a complex combination of various surgical and non-surgical therapies.

Abstract
BACKGROUND Intestinal complaints are a frequent health concern for elderly people and their care providers. AIMS To explore the distinction between constipation and the subjective complaints in elderly people and to review the diagnosis, causes and treatment of constipation, fecal impaction, and fecal incontinence. METHODS Review of studies that give information on prevalence, causes, symptoms, and treatment of bowel problems in the elderly, excluding uncontrolled clinical observations. RESULTS Self-reported constipation and laxative use increase with age and are more common among women, blacks and people of low socio-economic level. The patient's pharmacological history is fundamental, because medications are the cause of up to 40% of chronic constipation, and are often used inappropriately. The results of most laxative trials require cautious interpretation, but fiber and laxatives are more effective than placebo against constipation. Much additional research is needed to determine the most cost-effective method of treating intestinal complaints in the elderly. CONCLUSIONS Bowel problems in older people have a considerable impact on the quality of life and have many contributory causes that are often amenable to treatment and management. Results of therapy can be good, leading to alleviation of suffering and the ability to lead a fuller life.

Abstract
Tests for evaluating incontinence include endoanal ultrasound (EUS) and anorectal manometry. We hypothesized that EUS would be superior to anorectal manometry in identifying the subset of patients with surgically correctable sphincter defects leading to an improvement in clinical outcome in these patients. The purpose of this study was to compare these 2 techniques to determine which is more predictive of outcome for fecal incontinence. Thirty-five unselected patients with fecal incontinence were prospectively studied with EUS and anorectal manometry to evaluate the internal anal sphincter (IAS) and external anal sphincter (EAS). EUS was performed with Olympus GFUM20 echoendoscope and a hypoechoic defect in the EAS or IAS was considered a positive test. Anorectal manometry was performed with a standard water-perfused catheter system. A peak voluntary squeeze pressure of < 60 mm Hg in women and 120 mm Hg in men was considered a positive test. All patients were administered the Cleveland Clinic Continence Grading Scale at baseline and at follow-up. Improvement in fecal control was defined as a 25% or greater decrease in continence score. EUS versus manometry were compared with subsequent surgical treatment and outcome. P-values were calculated using Fisher's exact test. Patients (n = 32; 31 females) were followed for a mean 25 months (range 13-46). Sixteen patients had improved symptoms (50%). There was no correlation between EUS or anorectal manometry sphincter findings and outcome. Seven of 14 (50%) patients who subsequently underwent surgery versus 9 of 18 (50%) without surgery improved (P = .578). In long-term follow-up, approximately half of patients improve regardless of the results of EUS or anorectal manometry, or whether surgery is performed.

Abstract
PURPOSE To prospectively compare external phased-array magnetic resonance (MR) imaging with endoanal MR imaging in depicting external and internal anal sphincter defects in patients with fecal incontinence and to prospectively evaluate observer reproducibility in the detection of external and internal anal sphincter defects with both MR imaging techniques. MATERIALS AND METHODS The medical ethics committees of both participating hospitals approved the study, and informed consent was obtained. Thirty patients (23 women, seven men; mean age, 58.7 years; range, 37-78 years) with fecal incontinence underwent MR imaging with both endoanal and external phased-array coils. MR images were evaluated by three radiologists with different levels of experience for external and internal anal sphincter defects. Measures of inter- and intraobserver agreement of both MR imaging techniques and of differences between both imaging techniques were calculated. RESULTS Both MR imaging techniques did not significantly differ in the depiction of external (P > .99) and internal (P > .99) anal sphincter defects. The techniques corresponded in 25 (83%) of 30 patients for the depiction of external anal sphincter defects and in 28 (93%) of 30 patients for the depiction of internal anal sphincter defects. Interobserver agreement was moderate to good for endoanal MR imaging and poor to fair for external phased-array MR imaging. Intraobserver agreement ranged from fair to very good for both imaging techniques. CONCLUSION External phased-array MR imaging is comparable to endoanal MR imaging in the depiction of clinically relevant anal sphincter defects. Because of the weak interobserver agreement, both MR imaging techniques can be recommended in the diagnostic work-up of fecal incontinence only if sufficient experience is available.

Abstract
Endoanal and endorectal ultrasound have an important role in colorectal surgery. They can be applied in the management of faecal incontinence, rectal tumours and inflammatory perianal conditions. In faecal incontinence, anal ultrasound will confirm the presence or absence of sphincter defects. This will direct any operative intervention such as direct sphincter repair. Ultrasound in rectal cancer allows staging of the tumour by assessing the depth of invasion through the bowel wall and involvement of mesenteric nodes. Such staging might influence the choice of operation and determine which patients might benefit from preoperative chemotherapy and radiotherapy. Ultrasound has a particular role in recurrent and complex anal fistula and perianal sepsis. Preoperative and perioperative planning with accurate delineation of fistula tracts, extensions and sphincter involvement might help prevent recurrence and impaired continence from sphincter damage after surgery. Correct interpretation of ultrasound images requires training and experience so that the results can be properly correlated with the clinical situation.

Abstract
Faecal incontinence is a distressing and socially debilitating problem. Nurses are ideally placed to support patients and assist them in improving their quality of life. In order to provide the necessary holistic care the nurse needs to understand the nature of the patient's symptoms and be aware of a variety of management interventions. In this article the author outlines the various causes of faecal incontinence and highlights the importance of a thorough nursing assessment which takes into account the physical, psychological and social aspects of the symptoms. Planned care should be based on a firm knowledge base, but should reflect the needs of the individual. A good nurse-patient interaction facilitates this process and should be valued.

Abstract
Anorectal disorders, such as faecal incontinence, defecation difficulty and conditions associated with anorectal pain, are commonly encountered in the practices of gastroenterologists, urogynaecologists and colorectal surgeons. The evaluation of these disorders has been very much improved by the development and wider availability of diagnostic tests, such as manometry, endo-anal ultrasound, static and dynamic pelvic magnetic resonance imaging and electromyography. After briefly reviewing the normal anatomy and physiology of the anorectum, the pathophysiology and diagnostic approaches to faecal incontinence, defecation disorders and functional anorectal pain are discussed. Until recently, the management of these disorders has been largely anecdotal. However, our therapeutic armamentarium has been expanded by pharmacological agents, such as nitrates, calcium channel blockers and botulinum toxin, as well as the development of novel techniques, such as sacral nerve stimulation. These and other pharmacological, behavioural and surgical approaches are reviewed with respect to the robustness of evidence to support their efficacy in patients with these disorders.

Abstract
PURPOSE This study was designed to determine whether anorectal physiology testing significantly altered patient management in the setting of fecal incontinence. METHODS Patients referred to the anorectal physiology laboratory for evaluation of fecal incontinence were prospectively interviewed and examined by a colon and rectal surgeon. A decision to treat either medically or surgically was reached. The patients underwent physiologic testing with transanal ultrasound, pudendal nerve terminal motor latency, and anorectal manometry. A panel of board-certified colon and rectal surgeons then reviewed the history and physical examination, as well as the anorectal physiology tests, of each patient and reached a consensus on management. Management plans before and after physiologic evaluation were compared. RESULTS Ninety patients (6 males) were entered into the study. The patients were divided in two groups: those with pretest medical management plans (n = 45) and those with pretest surgical management plans (n = 45). A change in management was noted in nine patients (10 percent). In the medical management group, the management changed from medical to surgical therapy in five patients. Transanal ultrasound detected anal sphincter defects in all patients who changed from medical to surgical management but in only 10 percent of those who remained under medical management (P = 0.0001). In the surgical management group, three patients (7 percent) changed from surgical to medical therapy and one patient (2 percent) changed from sphincteroplasty to neosphincter. Transanal ultrasound detected a limited anal sphincter defect in one patient (33 percent) who changed from surgical to medical management and a significant defect in all 41 patients (100 percent) who remained under surgical management (P = 0.003). CONCLUSIONS Anorectal physiology testing is useful in the evaluation of patients with fecal incontinence. Without the information obtained from physiologic testing, 11 percent of patients who may have benefited from surgery would not have been given this option, and 7 percent of patients could have potentially undergone unnecessary surgery. Transanal ultrasound is the study most likely to change a patient's management plan.

Abstract
A greater awareness of the therapies now available for pelvic floor dysfunction has increased demand for specialized imaging of this region. Some of the techniques required are available at relatively few centers, and the purpose of this review is to introduce the emerging subspecialty of pelvic floor imaging to a more general readership. Pelvic floor anatomy is complex and is being unraveled by means of magnetic resonance (MR) imaging. This is discussed in detail by using a global, rather than a compartmentalized, anatomic approach. The physiology of normal urinary and anal function and the routine clinical tests applied to them are outlined. The imaging techniques involved include MR imaging, endosonography, and fluoroscopy. The main investigations include video urodynamic imaging, evacuation proctography, dynamic cystoproctography, dynamic MR imaging of the pelvic floor, and endoluminal imaging of the anal sphincters with MR imaging and ultrasonography. These are described in detail, and their role with regard to the main pathologic conditions of the pelvic floor--urinary and anal incontinence, constipation, and prolapse--are discussed.

Abstract
PURPOSE Fecal incontinence is a socially devastating disorder which affects at least 2.2 percent of community dwelling adults and 45 percent of nursing home residents. Most incontinent patients can be helped, but physicians are poorly informed about treatment options. The aim of this study was to develop a consensus on treatment options by convening a conference of surgeons, gastroenterologists, nurses, psychologists, and patient advocates. METHOD A 1-1/2 day conference was held in April, 1999. Experts from different disciplines gave overviews, followed by extended discussions. Consensus statements were developed at the end of the conference. This summary statement was drafted, circulated to all participants, and revised based on their input. CONCLUSIONS 1) Diarrhea is the most common aggravating factor for fecal incontinence, and antidiarrheal medications such as loperamide and diphenoxylate or bile acid binders may help. Fecal impaction, a common cause of fecal incontinence in children and elderly patients, responds to combinations of laxatives, education, and habit training in approximately 60 percent. These causes of fecal incontinence can usually be identified by history and physical examination alone. 2) In patients who fail medical management or have evidence of sphincter weakness, anorectal manometry and endoanal ultrasound are recommended as helpful in differentiating simple morphologic defects from afferent and efferent nerve injuries and from combined structural and neurologic injuries. 3) Biofeedback is a harmless and inexpensive treatment which benefits approximately 75 percent of patients but cures only about 50 percent. It may be most appropriate when there is neurologic injury (i.e., partial denervation), but it has been reported to also benefit incontinent patients with minor structural defects. 4) External anal sphincter plication with or without pelvic floor repair is indicated when there is a known, repairable structural defect without significant neurologic injury. It is effective in approximately 68 percent. 5) Salvage operations are reserved for patients who can not benefit from biofeedback or levator-sphincteroplasty. These include electrically stimulated gracilis muscle transpositions and colostomy. 6) Antegrade enemas delivered through stomas in the cecum or descending colon reduce or eliminate soiling in approximately 78 percent of children with myelomeningocele; this operation may come to be more widely applied. 7) Investigational treatments include implanted nerve stimulators, artificial sphincters, and anal plugs. 8) Patient characteristics which influence choice of treatment include mental status, mobility impairment, and typical bowel habits. 9) Additional research is needed to better define the mechanisms responsible for fecal incontinence, to assess the efficacy of these treatments, to develop better treatments for nursing home residents, and to identify predictors of outcome.

Abstract
BACKGROUND Surgical treatment of end-stage faecal incontinence has its origin in the early 1950s. Interest has been revived as a result of technical advances achieved in the recent past. The purpose of this article is to review the principles that underlie the use of skeletal muscle transposition around the anal canal and of electrical stimulation in the treatment of incontinence, and to explore new methods of treatment of this condition. METHODS A literature search was performed using Pubmed and Medline, employing keywords related to treatment of faecal incontinence by neosphincter reconstruction. Basic science and clinical aspects of neosphincter reconstruction were gathered from relevant texts, original articles and recently published abstracts. RESULTS The electrically stimulated gracilis neoanal sphincter seems to be the popular choice of biological neosphincter. It is more likely to produce higher resting anal canal pressures than the unstimulated neosphincter, and hence improved continence. However, electrostimulator failure may result in explantation in a proportion of patients. Impairment of evacuation is a functional setback in approximately one-third of patients with the gracilis neosphincter. Overall, improvement of continence may be expected in up to 90 per cent of patients according to some reports. By contrast, experience with the artificial neosphincter, which is less expensive, has been limited to a few tertiary centres across the world. Reported continence of stool is 100 per cent, and that of gas and stool 50 per cent, following implantation of the artificial sphincter. Both of the above operations have been associated with implant-related infection and impaired evacuation. CONCLUSION Neoanal sphincter operations are technically demanding, require a considerable learning experience and should be confined to specialist colorectal centres. Patients are likely to benefit from a plan that incorporates preoperative counselling and a selective approach.

Abstract
OBJECTIVE Anorectal physiological testing often yields contradictory results in patients with faecal incontinence. This prospective study aims to determine if there are any discriminatory changes in anorectal physiological testing after a successful sphincter repair for sphincter defects. PATIENTS AND METHODS From 1995 to 1998, 20 consecutive females who underwent a successful overlapping sphincter repair for sphincter defect were evaluated by anorectal manometry and neurophysiologic testing before and 2-4 months after surgery. The sphincter defect was diagnosed preoperatively by clinical and endosonographic examination, confirmed at surgery. The severity of faecal incontinence was evaluated using the Cleveland Clinic Continence Score (0-20): 0 being perfect continence, and 20 being complete incontinence. RESULTS Of 20 consecutive patients who were improved following direct sphincter repair, 12 had significant improvement with a median score of 3 (range 1-6), while eight had mild improvement with a median score of 9 (range 7-12). There was a significant improvement in the mean resting anal canal pressure (80 vs 50 mmHg; P=0.016), maximum squeeze anal canal pressure (120 vs 80 mmHg; P=0.0002) and functional anal canal length (3 vs 2 cm; P=0.0069) post-operatively, with significant improvement in faecal continence following sphincter repair. However, a mild improvement in faecal continence was not associated with any significant changes in the mean resting anal canal pressure (50 vs 40 mmHg; P=0.089), maximum squeeze anal canal pressures (100 vs 100 mmHg; P=0.19) or functional anal canal length (2 vs 2 cm; P=0.47). CONCLUSION Marked improvement of faecal continence after overlapping sphincter repair is reflected by a marked increase in the mean resting anal canal pressure, maximum squeeze anal canal pressures and functional anal canal length.

Abstract
BACKGROUND Over the past two decades developments in imaging have changed the assessment of patients with anorectal disease. METHODS The literature on imaging techniques for anorectal diseases was reviewed over the period 1980-1999. RESULTS For the staging of primary rectal tumours, phased array magnetic resonance imaging (MRI) may be regarded as the most appropriate single technique. The combination of endosonography or endoluminal MRI with ultrasonography or spiral computed tomography yields similar results. All techniques have limitations both for local staging and in the assessment of distant metastases. MRI or positron emission tomography is preferable for tumour recurrence. For perianal fistula, high-resolution MRI (phased array or endoluminal) is the technique of choice. For constipation, defaecography is the preferred technique, nowadays with emphasis on functional information. The role of magnetic resonance defaecography is currently being evaluated. For faecal incontinence, endosonography and endoluminal MRI give similar results in detecting sphincter defects; endoluminal MRI has the advantage of detecting external sphincter atrophy. CONCLUSION High-resolution MRI, endosonography and defaecography are currently the optimal imaging techniques for anorectal disease.

Abstract
BACKGROUND Faecal incontinence is a debilitating problem with significant medical, social and economic implications. Treatment options include conservative, non-operative interventions (e.g. pelvic floor muscle training, biofeedback, drugs) and surgical procedures. Surgery is used in selected groupsof people when the structural and functional defects in the pelvic floor muscles or the anal sphincter complex can be corrected mechanically. OBJECTIVES To assess the effects of established surgical techniques for the treatment of faecal incontinence in adults who do not have rectal prolapse. Our aims were firstly to compare surgical management with non-surgical management and secondly, to compare the various surgical techniques. SEARCH STRATEGY We searched the Cochrane Incontinence Group trials register, the Cochrane Colorectal Cancer Group trials register, the Cochrane Controlled Trials Register (Issue 2, 1999), Medline (up to March 1999), Embase (1998 up to January 1999), Sigle (1980 up to December 1996), Biosis (1998 up to March 1999), SCI (1998 up to March 1999), ISTP (1982 up to March 1999) and the reference lists of relevant articles. We specifically hand searched the British Journal of Surgery from 1995 to 1998 and the Diseases of the Colon and Rectum from 1995 to 1998. We also perused the proceedings of the Association of Coloproctology, meeting 1999. Date of the most recent literature searches: March 1999. SELECTION CRITERIA All randomised or quasi-randomised trials of surgery in the management of adult faecal incontinence (other then surgery for rectal prolapse). DATA COLLECTION AND ANALYSIS Two reviewers independently selected studies from the literature, extracted data and assessed the methodological quality of eligible trials. The three primary outcome measures were: change or deterioration in incontinence, failure to achieve full continence, and the presence of faecal urgency. MAIN RESULTS Four trials were included with a total sample size of 110 participants. All trials excluded women with anal sphincter defects detected by endoanal ultrasound examination. No trial included a group managed non-surgically. Two trials (56 participants) compared three approaches to pelvic floor repair (anterior levatorplasty, postanal repair and their combination total pelvic floor repair). One trial (30 participants) evaluated adding plication of the anal sphincter to total pelvic floor repair. The fourth trial (24 participants) compared a neosphincter procedure with total pelvic floor repair. No differences in the primary outcomes were detected, but data were few and inconsistently reported. REVIEWER'S CONCLUSIONS The small number of relevant trials identified together with their small sample sizes and other methodological weaknesses severely limit the usefulness of this review for guiding practice. It was impossible to identify or refute clinically important differences between the alternative surgical procedures. Larger rigorous trials are needed.

Abstract
PURPOSE The purpose of our study was to define the role of endoanal ultrasound in the evaluation and management of patients with rectovaginal fistula. METHODS A retrospective review was performed of all patients with rectovaginal fistula who were evaluated by endoanal ultrasound at Barnes-Jewish Hospital at Washington University from 1992 to 1997. RESULTS Twenty-five females underwent endoanal ultrasound before rectovaginal fistula repair. Mean age was 34 years. Rectovaginal fistulas were caused by obstetric trauma (19 patients; 76 percent), cryptoglandular disease (5 patients; 20 percent), and Crohn's disease (1 patient; 4 percent). Previous rectovaginal fistula repair had been performed in ten patients (40 percent). A history of anal incontinence was present in ten patients (40 percent). Rectovaginal fistula location was above (15 patients), at (7 patients), or below (3 patients) the dentate line. Rectovaginal fistula size was <5 mm (19 patients; 76 percent) or >5 mm (6 patients; 24 percent). Anal manometry revealed decreased sphincter pressures (resting or squeeze) in 12 patients (48 percent). Pudendal nerve latency was abnormal in three patients (9 percent). Endoanal ultrasound identified the rectovaginal fistula in 7 patients (28 percent) and an anterior sphincter defect in 23 patients (92 percent). At surgery sphincter injuries were identified in 23 patients (92 percent). Treatment was either sliding flap repair with anal sphincter reconstruction (22 patients; 88 percent) or sliding flap repair alone (3 patients; 12 percent). Repair of the rectovaginal fistula was successful in 23 patients (92 percent). Complications occurred in 11 patients (44 percent): two recurrent rectovaginal fistulas, five infections, two skin separations, one ectropion, and one hematoma. The two patients with recurrent rectovaginal fistula had prior repairs, and both were subsequently repaired successfully. Of the 11 patients with preoperative anal incontinence, 6 patients (54 percent) were continent and 2 (18 percent) improved after surgery. Cause, size, location, and previous repair of fistula had no effect on final outcome. CONCLUSIONS Noncontrast endoanal ultrasound was not useful in imaging rectovaginal fistulas and cannot be recommended as a diagnostic or screening tool for the identification of a rectovaginal fistula. However, we recommend that endoanal ultrasound be performed preoperatively in all patients with known rectovaginal fistulas to identify and map occult sphincter defects. Concomitant anal sphincter reconstruction should be considered strongly in patients with rectovaginal fistula and an endoanal ultrasound-documented sphincter defect.

Abstract
PURPOSE Controversy exists in regard to the prognostic value of clinical data and physiological tests in patients undergoing sphincter repair for fecal incontinence. The aim of this study was to identify prognostic factors. METHODS Between 1986 and 1996, 405 consecutive patients had a sphincter repair for fecal incontinence. Preoperative and postoperative manometric data were available on 51 of these patients, and these patients' charts were reviewed retrospectively. Preoperative and postoperative continence was scored using the four-level scale of Browning and Parks. Mean follow-up was 16.2 (median, 6; range, 1-96) months. Mean age was 41 (median, 36; range, 21-80) years, and 46 (90 percent) patients were female. RESULTS Twenty-three (45 percent) patients had perfect continence postoperatively, whereas 41 (80 percent) patients demonstrated improvement in continence score after sphincter repair. Using univariate analysis, various clinical and anal physiologic data were analyzed for an association with postoperative continence score. Postoperative mean resting pressure and postoperative anal canal length were both significantly related to postoperative continence (r(s)B for Spearman correlation coefficient to differentiate from r for the Pearson coefficient. = 0.442; P = 0.0012; and r(s) = 0.440; P = 0.0012, respectively), whereas postoperative mean squeeze pressure was not (r(s) = 0.273; P = 0.0529). Postoperative mean resting pressure and anal canal length were entered into a logistic regression model. Postoperative mean resting pressure was not significant (P = 0.6643), and when it was dropped from the model, postoperative anal canal length was highly significant (estimated odds ratio, 3.2; 95 percent confidence interval, 1.1-9.3; P = 0.0047) in predicting postoperative continence. CONCLUSIONS No preoperative data predicted functional outcome, and in contrast to other studies, postoperative anal canal length provides the best prediction of postoperative continence.
