Multimodal rehabilitation for faecal incontinence: experience of an Italian centre devoted to faecal disorder rehabilitation

Patient-Reported Outcome Measures in Colon and Rectal Surgery: A Systematic Review and Quality Assessment

BACKGROUND

There is growing interest in using patient-reported outcome measures to support value-based care in colorectal surgery. To draw valid conclusions regarding patient-reported outcomes data, measures with robust measurement properties are required.

OBJECTIVE

The purpose of this study was to assess the use and quality of patient-reported outcome measures in colorectal surgery.

DATA SOURCES

Three major databases were searched for studies using patient-reported outcome measures in the context of colorectal surgery.

STUDY SELECTION

Articles that used patient-reported outcome measures as outcome for colorectal surgical intervention in a comparative effectiveness analysis were included. Exclusion criteria included articles older than 11 years, non-English language, age <18 years, fewer than 40 patients, case reports, review articles, and studies without comparison.

MAIN OUTCOME MEASURES

This was a quality assessment using a previously reported checklist of psychometric properties.

RESULTS

From 2007 to 2018, 368 studies were deemed to meet inclusion criteria. These studies used 165 distinct patient-reported outcome measures. Thirty were used 5 or more times and were selected for quality assessment. Overall, the measures were generally high quality, with 21 (70%) scoring ≥14 on an 18-point scale. Notable weaknesses included management of missing data (14%) and description of literacy level (0%).

LIMITATIONS

The study was limited by its use of original articles for quality assessment. Measures were selected for quality analysis based on frequency of use rather than other factors, such as impact of the article or number of patients in the study.

CONCLUSIONS

Patient-reported outcome measures are widely used in colorectal research. There was a wide range of measures available, and many were used only once. The most frequently used measures are generally high quality, but a majority lack details on how to deal with missing data and information on literacy levels. As the use of patient-reported outcome measures to assess colorectal surgical intervention increases, researchers and practitioners need to become more knowledgeable about the measures available and their quality.

OUTLET OBSTRUCTED CONSTIPATION AND FECAL INCONTINENCE: IS REHABILITATION TREATMENT THE WAY? MYTH OR REALITY

Pelvic floor rehabilitation aims to address perineal functional and anatomic alterations as well as thoraco-abdominal mechanic dysfunctions leading to procto-urologic diseases like constipation, fecal and urinary incontinence, and pelvic pain. They require a multidimensional approach, with a significant impact on patients quality of life. An exhaustive clinical and instrumental protocol to assess defecation disorders should include clinical and instrumental evaluation as well as several clinical/physiatric parameters. All these parameters must be considered in order to recognize and define any potential factor playing a role in the functional aspects of incontinence, constipation and pelvic pain. After such evaluation, having precisely identified any thoraco-abdomino-perineal anatomic and functional alterations, a pelvi-perineal rehabilitation program can be carried out to correct the abovementioned alterations and to obtain clinical improvement. The success of the rehabilitative process is linked to several factors such as a careful evaluation of the patient, aimed to select the most appropriate and specific targeted rehabilitative therapy, the therapist's scrupulous hard work, especially as regards the patient's emotional and psychic state, and finally the patient's compliance in undertaking the therapy itself, especially at home. These factors may deeply influence the overall outcomes of the rehabilitative therapies, ranging from "real" success to illusion "myth".

Consensus Statement of the Italian Society of Colorectal Surgery (SICCR): management and treatment of complete rectal prolapse

Rectal prolapse, rectal procidentia, "complete" prolapse or "third-degree" prolapse is the full-thickness prolapse of the rectal wall through the anal canal and has a significant impact on quality of life. The incidence of rectal prolapse has been estimated to be approximately 2.5 per 100,000 inhabitants with a clear predominance among elderly women. The aim of this consensus statement was to provide evidence-based data to allow an individualized and appropriate management and treatment of complete rectal prolapse. The strategy used to search for evidence was based on application of electronic sources such as MEDLINE, PubMed, Cochrane Review Library, CINAHL and EMBASE. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Gastroenterology's Chronic Constipation Task Force. Five evidence levels were defined. The recommendations were graded A, B, and C.

Semi-closed bilateral partial miotomy of the puborectalis for anismus: a pilot study: Partial miotomy of the puborectalis for anismus

BACKGROUND

Anismus or non relaxing puborectalis muscle (PRM) may cause obstructed defecation (OD). Reported surgical treatment is partial miotomy, followed by sepsis, bleeding, and incontinence. The aim of the present study was to investigate on the feasibility and outcome of a modified mini-invasive operation.

PATIENTS AND METHODS

Consecutive patients with anismus and OD not responding to medical therapy, excluding multiparous females, patients with anal incontinence, recto-rectal intussusception, and disordered psychological pattern. Semi-closed bilateral partial division of PRM, pulled down through 1-cm perianal incisions, was performed. Concomitant significant rectal mucosal prolapse and rectocele, when present, were treated. OD was evaluated using a validated score and anal/vaginal ultrasound (US) was performed pre -and postoperatively. A control group of seven patients with normal bowel habit was also investigated.

RESULTS

Eight patients (seven females), median age 48 years (range 29-71) were operated. Six also had significant mucosal prolapse and rectocele. All were followed up for a median of 12 months (range 2-40). None of them had postoperative sepsis or bleeding. One had just one occasional episode of mild anal incontinence. Symptoms improved in 6 or 75 % and, OD score decreased from 19.6 ± 1.0 to 9.2 ± 2.0 (mean ± s.e.m.), P = 0.007. No patient had anismus after surgery and PRM relaxation changed from 0 to 5.9 ± 0.8 mm being 6.6 ± 1.5 mm in controls.

CONCLUSION

Semi-closed bilateral partial division of PRM achieves muscle's relaxation on straining in all patients without any significant postoperative complication. Further studies are needed prior to consider it a validated procedure.

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.

Management of obstructed defecation

The management of obstructed defecation syndrome (ODS) is mainly conservative and mainly consists of fiber diet, bulking laxatives, rectal irrigation or hydrocolontherapy, biofeedback, transanal electrostimulation, yoga and psychotherapy. According to our experience, nearly 20% of the patients need surgical treatment. If we consider ODS an “iceberg syndrome”, with “emerging rocks”, rectocele and rectal internal mucosal prolapse, that may benefit from surgery, at least two out of ten patients also has “underwater rocks” or occult disorders, such as anismus, rectal hyposensation and anxiety/depression, which mostly require conservative treatment. Rectal prolapse excision or obliterative suture, rectocele and/or enterocele repair, retrograde Malone’s enema and partial myotomy of the puborectalis muscle are effective in selected cases. Laparoscopic ventral sacral colporectopexy may be an effective surgical option. Stapled transanal rectal resection may lead to severe complications. The Transtar procedure seems to be safer, when dealing with recto-rectal intussusception. A multidisciplinary approach to ODS provides the best results.

Epidemiology, pathophysiology, and classification of fecal incontinence: state of the science summary for the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) workshop

In August 2013, the National Institutes of Health sponsored a conference to address major gaps in our understanding of the epidemiology, pathophysiology, and management of fecal incontinence (FI) and to identify topics for future clinical research. This article is the first of a two-part summary of those proceedings. FI is a common symptom, with a prevalence that ranges from 7 to 15% in community-dwelling men and women, but it is often underreported, as providers seldom screen for FI and patients do not volunteer the symptom, even though the symptoms can have a devastating impact on the quality of life. Rough estimates suggest that FI is associated with a substantial economic burden, particularly in patients who require surgical therapy. Bowel disturbances, particularly diarrhea, the symptom of rectal urgency, and burden of chronic illness are the strongest independent risk factors for FI in the community. Smoking, obesity, and inappropriate cholecystectomy are emerging, potentially modifiable risk factors. Other risk factors for FI include advanced age, female gender, disease burden (comorbidity count, diabetes), anal sphincter trauma (obstetrical injury, prior surgery), and decreased physical activity. Neurological disorders, inflammatory bowel disease, and pelvic floor anatomical disturbances (rectal prolapse) are also associated with FI. The pathophysiological mechanisms responsible for FI include diarrhea, anal and pelvic floor weakness, reduced rectal compliance, and reduced or increased rectal sensation; many patients have multifaceted anorectal dysfunctions. The type (urge, passive or combined), etiology (anorectal disturbance, bowel symptoms, or both), and severity of FI provide the basis for classifying FI; these domains can be integrated to comprehensively characterize the symptom. Several validated scales for classifying symptom severity and its impact on the quality of life are available. Symptom severity scales should incorporate the frequency, volume, consistency, and nature (urge or passive) of stool leakage. Despite the basic understanding of FI, there are still major knowledge gaps in disease epidemiology and pathogenesis, necessitating future clinical research in FI.

Psycho-echo-biofeedback: a novel treatment for anismus--results of a prospective controlled study

BACKGROUND

Anismus or non-relaxing puborectalis muscle (PRM), detectable with anal/vaginal ultrasound (US), is a cause of obstructed defecation (OD) and may be treated with biofeedback (BFB). Many patients with anismus are anxious and/or depressed. The aim of this prospective study was to evaluate the outcome of the novel procedure psycho-echo-BFB in patients with anismus and psychological disorders.

METHODS

Patients presenting at our unit with anismus and psychological disorders between January 2009 and December 2013, and not responding to conventional conservative treatment, were enrolled in the study. All underwent four sessions of psycho-echo-BFB, carried out by two psychologists and a coloproctologist, consisting of guided imagery, relaxation techniques and anal/vaginal US-assisted BFB. A validated score for OD was used, and PRM relaxation on straining measured before and after the treatment. PRM relaxation was also measured in a control group of 7 patients with normal bowel habits.

RESULTS

Ten patients (8 females, median age 47 years, range 26-72 years) underwent psycho-echo-BFB. The OD score, evaluated prior to and at a median of 25 months (range 1-52 months) after the treatment, improved in 7 out of 10 patients, from 13.5 ± 1.2 to 9.6 ± 2.2 (mean ± standard error of the mean (SEM)), p = 0.06. At the end of the last session, PRM relaxed on straining in all cases, from 0 to 7.1 ± 1.1 mm, i.e., physiological values, not statistically different from those of controls (6.6 ± 1.5 mm). Two patients reported were cured, 3 improved and 5, all of whom had undergone prior anorectal surgery, unchanged. No side effects were reported.

CONCLUSIONS

Psycho-echo-BFB is safe and inexpensive and allows all patients with anismus to relax PRM on straining. Previous anorectal surgery may be a negative predictor.

Conservative treatment for anal incontinence

Anal incontinence (AI) in adults is a troublesome condition that negatively impacts upon quality of life and results in significant embarrassment and social isolation. The conservative management of AI is the first step and targets symptomatic relief. The reported significant improvement with conservative treatments for AI is close to 25% and involves prescribed changes in lifestyle habits, a reduced intake of foods that may cause or aggravate diarrhea or rectal urgency, and the use of specific anti-diarrheal agents. The use of a mechanical barrier in the form of an anal plug and the outcomes and principles of pelvic kinesitherapies and biofeedback options are outlined. This review discusses a gastroenterologist's approach towards conservative therapy in patients referred with anal incontinence.

Short-term outcomes after rehabilitation treatment in patients selected by a novel rehabilitation score system (Brusciano score) with or without previous stapled transanal rectal resection (STARR) for rectal outlet obstruction

PURPOSE

The purpose of this study was to examine short-term outcomes of rehabilitation treatment in patients with or without previous stapled transanal resection (STARR) for rectal outlet obstruction by using a novel rehabilitation score system (Brusciano score).

METHODS

This is a retrospective cohort study conducted at a single tertiary referral institution including all patients with chronic functional constipation admitted to the outpatient unit from 2004 to 2009.

RESULTS

Among 330 consecutive patients, 247 (74.8 %) (204 females and 43 males) showing a significantly higher rehabilitation score (mean of 15.7 ± 1.8; range, 7-25) than healthy controls (mean, 3.2 ± 1.2; range 2-6) (p < .0001) were selected for rehabilitation. Of the 247 patients evaluated, group A (no previous surgery) consisted of 170 patients (53 males; mean age, 44.8 ± 12.9 years; range, 19-80) of which 38 presented mixed constipation, whereas group B (previous surgery) consisted of 77 patients (18 males; mean age, 47.0 ± 11.2 years; range, 22-81). The Brusciano score, Agachan-Wexner score and quality of life improved in both groups of patients after treatment. Better improvements of Brusciano and Agachan-Wexner scores were observed in patients with previous STARR (group B).

CONCLUSIONS

The rehabilitation score system employed in this study seems to be a useful tool in selecting and assessing the outcome of patients who might benefit from rehabilitation treatment. Constipation and quality of life were significantly improved by the rehabilitation treatment. Further studies are needed to clarify either the impact of rehabilitation treatment on long-term outcome of patients treated for rectal outlet obstruction or its role in those who develop problems over time.

Consensus statement AIGO/SICCR diagnosis and treatment of chronic constipation and obstructed defecation (part II: treatment)

The second part of the Consensus Statement of the Italian Association of Hospital Gastroenterologists and Italian Society of Colo-Rectal Surgery reports on the treatment of chronic constipation and obstructed defecation. There is no evidence that increasing fluid intake and physical activity can relieve the symptoms of chronic constipation. Patients with normal-transit constipation should increase their fibre intake through their diet or with commercial fibre. Osmotic laxatives may be effective in patients who do not respond to fibre supplements. Stimulant laxatives should be reserved for patients who do not respond to osmotic laxatives. Controlled trials have shown that serotoninergic enterokinetic agents, such as prucalopride, and prosecretory agents, such as lubiprostone, are effective in the treatment of patients with chronic constipation. Surgery is sometimes necessary. Total colectomy with ileorectostomy may be considered in patients with slow-transit constipation and inertia coli who are resistant to medical therapy and who do not have defecatory disorders, generalised motility disorders or psychological disorders. Randomised controlled trials have established the efficacy of rehabilitative treatment in dys-synergic defecation. Many surgical procedures may be used to treat obstructed defecation in patients with acquired anatomical defects, but none is considered to be the gold standard. Surgery should be reserved for selected patients with an impaired quality of life. Obstructed defecation is often associated with pelvic organ prolapse. Surgery with the placement of prostheses is replacing fascial surgery in the treatment of pelvic organ prolapse, but the efficacy and safety of such procedures have not yet been established.

A systematic review of psychometric evidence and expert opinion regarding the assessment of faecal incontinence in older community-dwelling adults

Objectives  This review had two objectives: (i) to determine what is required in an assessment of faecal incontinence issues for older community-dwelling adults; and (ii) to determine the psychometric tools most effective for assessment of faecal incontinence in older community-dwelling adults. Inclusion criteria  For the review of psychometric tools, studies were included if they were concerned with people living in the community, included a significant proportion of the sample aged 65 years or over, and either examined psychometric properties of assessment tools or assessed sensitivity of assessment tools to non-surgical interventions available in the community setting. For the review of expert opinion, the search was limited to expert opinion provided by an expert in faecal incontinence that related to community-based assessment. Only articles published in English were eligible for inclusion and no limits were placed on publication dates. Search strategy  An initial search of Medline and CINAHL databases identified terminology frequently used in the literature with regard to assessment of faecal incontinence. An extensive search was then undertaken using all identified key words and index terms. The third step involved a search of reference lists and bibliographies of all relevant articles. Methodological quality  All identified studies that met the inclusion criteria were assessed for methodological validity in the case of studies considered for inclusion in the psychometric review. Validity of expert text was also assessed prior to it being included in the review. Results  The final search strategy identified approximately 7000 references. Full-text versions of 144 references were critically appraised for inclusion in the review. Of these, 25 sources were included in the review of expert opinion and 16 in the review of psychometric properties. In the review of expert opinion, 254 conclusions were extracted for synthesis. The 31 thematic categories were organised under five major themes: History-taking, bowel assessment, psychosocial aspects, physical examination and specialist referral. From the sources that survived critical appraisal, 52 conclusions relating to psychometric properties of assessment tools were derived. There was limited, if any, analysis of psychometric properties for the majority of assessment tools. The Wexner and Vaizey symptom severity scales demonstrated acceptable test-retest reliability and convergent validity. The Fecal Incontinence Quality of Life Scale (FIQLS) demonstrated reasonable reliability and good convergent and criterion-related validity. There was, however, some evidence questioning its discriminant validity. Conclusions  This systematic review represents an important first stage in developing guidelines for assessment of faecal incontinence in community-dwelling older people. Assessment should be comprehensive in nature. Gaps in expert opinion are evident regarding issues such as assessment of cognitive decline and specialist referral. Continence advisors need to be appropriately trained in using and interpreting results from assessment tools and conducting physical examinations. Although studies in the review of psychometric properties suffer from limitations such as inadequate sample sizes, the Vaizey and Wexner scales would appear to be the tools of choice. The FIQLS is clearly the tool of choice at this stage for measuring faecal incontinence quality of life. Further validation of tests used in faecal incontinence assessments is required.

Clinical and instrumental parameters in patients with constipation and incontinence: their potential implications in the functional aspects of these disorders

PURPOSE

The aims of this study were to evaluate several clinical and instrumental parameters in a large number of patients with constipation and incontinence as well as in healthy controls and discuss their potential implications in the functional aspects of these disorders.

METHODS

Eighty-four constipated and 38 incontinent patients and 45 healthy controls were submitted to a protocol based on proctologic examination, clinico-physiatric assessment, and instrumental evaluation.

RESULTS

Constipated and incontinent patients had significantly worse lumbar lordosis as well as lower rate in the presence of perineal defense reflex than controls. Constipated but not incontinent patients had a lower rate of puborectalis relaxation than controls. Furthermore, worse pubococcygeal tests and a higher rate of muscle synergies presence, either agonist or antagonist, were observed in both constipated and incontinent patients compared to controls.

CONCLUSIONS

This study has demonstrated strong correlations between physiatric disorders and the symptoms of constipation and incontinence. Further studies designed to demonstrate a causal relationship between these parameters and the success of a specific treatment of the physiatric disorders on the proctology symptoms are warranted.

Long-term follow-up of simultaneous abdominoperineal repair of enterorectocele and internal mucosal prolapse

BACKGROUND

Enterorectocele with recto-rectal intussusception and internal mucosal prolapse (ER-RI-MP) may require surgery for obstructed defecation, but symptoms tend to recur if only one lesion is corrected. This prospective study was designed to investigate the results of an abdominoperineal procedure aimed at treating all these lesions in one stage.

METHODS

Thirteen women with constipation (median age, 58 years) and ER-RI-MP underwent Douglas pouch suture, mesh obliteration of the pelvic inlet with or without rectopexy, and omentoplasty plus rectocele and prolapse obliteration. Constipation was scored on a scale from 0 to 20. Proctoscopy, enterocolpodefecography, manometry, anal-vaginal-perineal ultrasound, and psychological evaluation were performed before and after surgery.

RESULTS

Bleeding requiring transfusion, pelvic hygroma, and ureteric stricture requiring adhesiolysis occurred in three patients. Constipation score significantly decreased from a mean (+/- standard error of the mean) of 16 +/- 0.6 before to 7 +/- 0.9 after surgery (P < 0.0001). Seven patients were considered cured, five improved, and one remained unchanged at a median follow-up of 42 months. Anorectal physiology and imaging returned to normal in seven patients. Four patients had successful rehabilitation and psychotherapy for anismus, rectal hyposensation, and depression.

CONCLUSIONS

Simultaneous abdominoperineal ER-RI-MP repair integrated with conservative treatment of associated dysfunctions achieved a satisfactory long-term outcome. The results need to be confirmed in larger series.

Rehabilitation of fecal incontinence after sphincter-saving surgery for rectal cancer: encouraging results

PURPOSE

Some patients, having undergone sphincter-saving operations for rectal cancer, may suffer from fecal incontinence. This study was designed to evaluate the results of rehabilitative treatment in patients with fecal incontinence after sphincter-saving operations and to identify the negative factors that influence therapeutic success.

METHODS

Between January 2000 and June 2007, 88 incontinent patients (54 women; age range, 47-73 years; 69 had received a low anterior rectal resection; 19 a straight coloanal anastomosis) were included in the study. After a preliminary clinical evaluation, including the Wexner Incontinence Scale score, anorectal manometry was performed. All 88 patients underwent rehabilitative treatment according to the "multimodal rehabilitative program" for fecal incontinence. At the end of program, all 88 patients were reassessed by means of a clinical evaluation and anorectal manometry; their results were compared with the clinical and manometric data from ten healthy control subjects. Postrehabilitative Wexner Incontinence Scale scores were used for an arbitrary schedule of patients divided into three classes: Class I, good (score </=3); Class II, fair (score >3 to </=6); Class III, poor (score >6).

RESULTS

After rehabilitation, there was a significant improvement in the overall mean Wexner Incontinence Scale score (P < 0.03) for both surgical operation types (low anterior rectal resection: P < 0.05; coloanal anastomosis: P < 0.02). Only 21 patients (23.8 percent) were symptom-free, and 37 (42 percent) were considered Class III. A significant postrehabilitative direct correlation was found between: 1) Wexner Incontinence Scale score and degree of genital relaxation (rrho (s) 0.78; P < 0.001); 2) Wexner Incontinence Scale score and irradiation (rrho (s) 0.72; P < 0.01); and 3) Wexner Incontinence Scale score and pelvic (rrho (s) 0.65; P < 0.01) or anal surgery (rrho (s) 0.68; P < 0.01). No significant differences were found between prerehabilitative and postrehabilitative anal pressures in low anterior rectal resection and coloanal anastomosis patients.

CONCLUSIONS

After rehabilitation, some patients become symptom-free, many patients show an improvement in the Wexner Incontinence Scale score, and others exhibit the highest grades of fecal incontinence. Genital relaxation, radiotherapy, and previous pelvic, and/or anal surgery are impeding factors to rehabilitative success.

Postoperative complications after procedure for prolapsed hemorrhoids (PPH) and stapled transanal rectal resection (STARR) procedures

Procedure for prolapsing hemorrhoids (PPH) and stapled transanal rectal resection for obstructed defecation (STARR) carry low postoperative pain, but may be followed by unusual and severe postoperative complications. This review deals with the pathogenesis, prevention and treatment of adverse events that may occasionally be life threatening. PPH and STARR carry the expected morbidity following anorectal surgery, such as bleeding, strictures and fecal incontinence. Complications that are particular to these stapled procedures are rectovaginal fistula, chronic proctalgia, total rectal obliteration, rectal wall hematoma and perforation with pelvic sepsis often requiring a diverting stoma. A higher complication rate and worse results are expected after PPH for fourth-degree piles. Enterocele and anismus are contraindications to PPH and STARR and both operations should be used with caution in patients with weak sphincters. In conclusion, complications after PPH and STARR are not infrequent and may be difficult to manage. However, if performed in selected cases by skilled specialists aware of the risks and associated diseases, some complications may be prevented.

An initial search of Medline and CINAHL databases identified terminology frequently used in the literature with regard to assessment of faecal incontinence. An extensive search was then undertaken using all identified key words and index terms. The third step involved a search of reference lists and bibliographies of all relevant articles.

METHODOLOGICAL QUALITY

All identified studies that met the inclusion criteria were assessed for methodological validity in the case of studies considered for inclusion in the psychometric review. Validity of expert text was also assessed prior to it being included in the review.

RESULTS

The final search strategy identified approximately 7000 references. Full-text versions of 144 references were critically appraised for inclusion in the review. Of these, 25 sources were included in the review of expert opinion and 16 in the review of psychometric properties. In the review of expert opinion, 254 conclusions were extracted for synthesis. The 31 thematic categories were organised under five major themes:History-taking, bowel assessment, psychosocial aspects, physical examination and specialist referral. From the sources that survived critical appraisal, 52 conclusions relating to psychometric properties of assessment tools were derived. There was limited, if any, analysis of psychometric properties for the majority of assessment tools. The Wexner and Vaizey symptom severity scales demonstrated acceptable test-retest reliability and convergent validity. The Fecal Incontinence Quality of Life Scale (FIQLS) demonstrated reasonable reliability and good convergent and criterion-related validity. There was, however, some evidence questioning its discriminant validity.

CONCLUSIONS

This systematic review represents an important first stage in developing guidelines for assessment of faecal incontinence in community-dwelling older people. Assessment should be comprehensive in nature. Gaps in expert opinion are evident regarding issues such as assessment of cognitive decline and specialist referral. Continence advisors need to be appropriately trained in using and interpreting results from assessment tools and conducting physical examinations. Although studies in the review of psychometric properties suffer from limitations such as inadequate sample sizes, the Vaizey and Wexner scales would appear to be the tools of choice. The FIQLS is clearly the tool of choice at this stage for measuring faecal incontinence quality of life. Further validation of tests used in faecal incontinence assessments is required.

The ProTect device in the treatment of severe fecal incontinence: preliminary results of a multicenter trial

BACKGROUND

Patients suffering from severe fecal incontinence (FI) in whom surgical treatment has either failed or is inappropriate due to high operative risks and those who refuse to undergo surgery are condemned to living with their embarrassing symptoms, often responsible for progressive social isolation. ProTect is a new, relatively simple, medical device intended for selected patients suffering from severe FI. It consists of a pliable, silicone catheter with an inflatable balloon that seals the rectum at the anorectal junction, acting like an anal plug. The proximal part of the catheter incorporates two contacts that monitor the rectum for the presence of feces. The patient is alerted to an imminent bowel movement and, hence, a potential fecal accident, through a beeper.

METHODS

A multicenter trial has been set up to assess the reliability of the device in preventing episodes of FI and to evaluate its impact on quality of life. Patients with significant FI (CCF>10) were prospectively entered into this 14-day study. Two quality of life questionnaires and a daily log of bowel activity and incontinent episodes were completed before and during the study.

RESULTS

Currently, the study enrolled 17 patients and 11 patients (9 women, 2 men) with a mean age of 66 years (range, 46-85) completed the trial. In these 11 subjects, there was an overall significant improvement in the quality of life (p<0.05) and a significant reduction in incontinence scores (p<0.001) while using ProTect compared to baseline.

CONCLUSIONS

The ProTect is a safe non-surgical device that is able to prevent episodes of FI. It is unique because it can be used according to a patient's needs without interfering with activities of daily living.

Gastrointestinal manifestations in myotonic muscular dystrophy

Myotonic dystrophy (MD) is characterized by myotonic phenomena and progressive muscular weakness. Involvement of the gastrointestinal tract is frequent and may occur at any level. The clinical manifestations have previously been attributed to motility disorders caused by smooth muscle damage, but histologic evidence of alterations has been scarce and conflicting. A neural factor has also been hypothesized. In the upper digestive tract, dysphagia, heartburn, regurgitation and dyspepsia are the most common complaints, while in the lower tract, abdominal pain, bloating and changes in bowel habits are often reported. Digestive symptoms may be the first sign of dystrophic disease and may precede the musculo-skeletal features. The impairment of gastrointestinal function may be sometimes so gradual that the patients adapt to it with little awareness of symptoms. In such cases routine endoscopic and ultrasonographic evaluations are not sufficient and targeted techniques (electrogastrography, manometry, electromyography, functional ultrasonography, scintigraphy, etc.) are needed. There is a low correlation between the degree of skeletal muscle involvement and the presence and severity of gastrointestinal disturbances whereas a positive correlation with the duration of the skeletal muscle disease has been reported. The drugs recommended for treating the gastrointestinal complaints such as prokinetic, anti-dyspeptic drugs and laxatives, are mainly aimed at correcting the motility disorders. Gastrointestinal involvement in MD remains a complex and intriguing condition since many important problems are still unsolved. Further studies concentrating on genetic aspects, early diagnostic techniques and the development of new therapeutic strategies are needed to improve our management of the gastrointestinal manifestations of MD.
