Pelvic floor behavioral treatment for fecal incontinence and constipation in quiescent inflammatory bowel disease.

BACKGROUND AND AIM: Refractory bowel symptoms in quiescent inflammatory bowel disease (IBD) are common but evidence for effective management is limited. We aimed to determine whether behavioral treatment, including pelvic floor muscle training, decreases the severity of functional bowel symptoms in patients with quiescent IBD. Secondary aims were to evaluate the treatment effect on quality of life, psychological well-being and pelvic floor muscle function. METHODS: This prospective study included IBD patients in remission with persistent symptoms of fecal incontinence or constipation who received up to six sessions of behavioral treatment at monthly intervals. The primary outcome was patient-rated symptom improvement on a 7-point Likert scale (1 = substantially worse, 7 = substantially better). Secondary outcomes included validated symptom scores, quality-of-life, psychological measures, and transperineal ultrasound assessment of pelvic floor muscle activity. RESULTS: Thirty-four patients (median age 38 years; 24 females; 18 ulcerative colitis, 13 Crohn's disease, 3 ileo-anal pouch) were included. Twenty-one of the 29 (72%) patients who completed treatment, or 21 of all 34 (62%) patients, reported moderate or substantial improvement (patient rating of 6 or 7). Symptom scores (p < .001), IBD-specific quality of life (p = .008) and illness perception scores (p = .003) significantly improved. General quality of life, and anxiety and depression scores, did not change significantly. Transperineal ultrasound pelvic floor measures did not correlate with patient-rating of symptom improvement. CONCLUSION: Significant symptomatic improvement occurred in a majority of patients with quiescent IBD. Behavioral treatment should be considered for patients with quiescent IBD and ongoing functional bowel symptoms of fecal incontinence, fecal urgency, or constipation.

Determinants of long-term function and general well-being in patients with an ileoanal pouch.

BACKGROUND AND AIM: Fecal incontinence and/or evacuation difficulty are common after ileoanal pouch surgery. This study aimed to determine whether the development of these symptoms can be predicted so that preventive measures might be instituted. METHODS: A consecutive series of 46 patients with ulcerative colitis (median age at surgery, 41 years; 50% female) and a functioning pouch for a duration ≥12 months was included. Assessment utilized medical record review and questionnaires on pre- and postoperative bowel function, quality of life, and psychological well-being. Pouch function was assessed by the Colorectal Functional Outcome score (0 = no impairment, 100 = worst impairment). Good pouch function was defined as a score ≤24. RESULTS: Fecal incontinence occurred in 67% preoperatively and 54% postoperatively; evacuation difficulty occurred in 65% and preoperatively and 85% postoperatively. The postoperative median Colorectal Functional Outcome score was 20 (range 2-74), with 44% of patients >24 (poor pouch function). Preoperative nocturnal fecal incontinence (odds ratio [OR] 4.92, 95% confidence interval [CI] 1.2-19.4, P = 0.02) and pouchitis (OR 5.41, 95% CI 1.2-23.7, P = 0.02) were associated with poor pouch function after multivariable regression analysis. Postoperative satisfaction, psychological well-being, and quality of life were significantly better in those with good pouch function, while poor sleep, impaired work, and sexual dysfunction were independently associated with poor pouch function. CONCLUSIONS: Functional bowel symptoms are common before and after pouch surgery and are associated with the impairment of patient-reported outcomes. Preoperative nocturnal fecal incontinence predicts poor pouch function. Therapeutic focus on continence, bowel evacuation, psychological well-being, and quality of life should begin before surgery.

Systematic review: Pelvic floor muscle training for functional bowel symptoms in inflammatory bowel disease.

BACKGROUND AND AIM: Large bowel functional symptoms are common in patients with inflammatory bowel disease (IBD) who are in disease remission. The efficacy of pelvic floor muscle training for symptoms of evacuation difficulty or fecal incontinence is well established in patients without organic bowel disease but is unknown in these patients. This study aimed to systematically evaluate the published evidence in this group of patients. METHODS: A systematic review was conducted of articles evaluating pelvic floor muscle training, with or without biofeedback, to improve bowel function in patients with quiescent IBD, including those with an ileoanal pouch. The outcome of interest was improved bowel function measured by bowel diary, patient report, or validated questionnaire in randomized controlled studies, cohort studies, or case series. RESULTS: Two randomized controlled trials, four retrospective case series, and one prospective study met eligibility criteria. Pelvic floor muscle training for patients with quiescent IBD improved symptoms in 51 of 76 (68%) patients with evacuation difficulty and 20 of 25 (80%) patients with fecal incontinence. Pelvic floor muscle training for patients with an ileoanal pouch, prior to stoma closure, did not appear to reduce the risk or severity of fecal incontinence following stoma closure. Studies were limited by small numbers, study design, methodological quality, and lack of long-term follow-up. CONCLUSION: Pelvic floor muscle training appears to be of therapeutic value in some patients with quiescent IBD and evacuation difficulty or fecal incontinence. The effectiveness of this approach warrants further investigation.

Gut-Directed Pelvic Floor Behavioral Treatment for Fecal Incontinence and Constipation in Patients with Inflammatory Bowel Disease.

BACKGROUND: Patients with inflammatory bowel disease (IBD) often experience functional bowel symptoms despite achieving disease remission. Although behavioral treatment (bowel and pelvic floor muscle retraining) is effective for managing constipation or fecal incontinence in non-IBD patients, there is limited evidence for its efficacy in patients with quiescent inflammatory bowel disease. The aim of this study was to evaluate the outcome of gut-directed behavioral treatment, including pelvic floor muscle training, for symptoms of constipation or fecal incontinence in patients with IBD in disease remission. METHODS: The outcome of consecutive patients with IBD in remission and symptoms of constipation or fecal incontinence was evaluated. Patients referred to a multidisciplinary gastroenterology clinic underwent gut-directed behavioral treatment, including pelvic floor muscle training. The primary outcome was patient-reported rating of change in symptoms on a 7-point Likert scale at the completion of treatment. RESULTS: Forty IBD patients (median age, 35 years; 80% female; 24 Crohn's disease [CD], 12 ulcerative colitis [UC], 4 UC with ileoanal pouch) with ongoing symptoms of constipation (55%) or fecal incontinence (45%), despite drug therapy, were included. The median symptom duration at referral was 2 years. Thirty-five (87%) completed treatment with a median of 2 sessions. Improvement of "6 = much better" or "7 = very much better" was reported by 77% (17/22) with fecal incontinence and 83% (15/18) with constipation. Improvement occurred irrespective of IBD diagnosis, previous perianal fistulae, colorectal surgery, presence of an ileoanal pouch, or past obstetric trauma. CONCLUSIONS: Behavioral treatment effectively improves functional gut symptoms in a large majority of patients who are in IBD disease remission and who have not responded to drug therapy. 10.1093/ibd/izy344_video1 izy344.video1 5968879349001.

Transabdominal electrical stimulation increases colonic propagating pressure waves in paediatric slow transit constipation.

BACKGROUND AND AIMS: In slow-transit constipation (STC) pancolonic manometry shows significantly reduced antegrade propagating sequences (PS) and no response to physiological stimuli. This study aimed to determine whether transcutaneous electrical stimulation using interferential current (IFC) applied to the abdomen increased colonic PS in STC children. METHODS: Eight children (8-18 years) with confirmed STC had 24-h colonic manometry using a water-perfused, 8-channel catheter with 7.5 cm sidehole distance introduced via appendix stomas. They then received 12 sessions (20 min/3× per week) of IFC stimulation (2 paraspinal and 2 abdominal electrodes), applied at a comfortable intensity (<40 mA, carrier frequency 4 kHz, varying beat frequency 80-150 Hz). Colonic manometry was repeated 2 (n=6) and 7 (n=2) months after IFC. RESULTS: IFC significantly increased frequency of total PS/24h (mean ± SEM, pre 78 ± 34 vs post 210 ± 62, p=0.008, n=7), antegrade PS/24h (43 ± 16 vs 112 ± 20, p=0.01) and high amplitude PS (HAPS/24h, 5 ± 2:10 ± 3, p=0.04), with amplitude, velocity, or propagating distance unchanged. There was increased activity on waking and 4/8 ceased using antegrade continence enemas. CONCLUSIONS AND INFERENCES: Transcutaneous IFC increased colonic PS frequency in STC children with effects lasting 2-7 months. IFC may provide a treatment for children with treatment-resistant STC.

Slow-transit constipation with concurrent upper gastrointestinal dysmotility and its response to transcutaneous electrical stimulation.

PURPOSE: Transcutaneous electrical stimulation (TES) speeds up colonic transit in children with slow-transit constipation (STC). This study examined if concurrent upper gastrointestinal dysmotility (UGD) affected response to TES. METHODS: Radio-nuclear transit studies (NTS) were performed before and after TES treatment of STC as part of a larger randomised controlled trial. UGD was defined as delayed gastric emptying and/or slow small bowel transit. Improvement was defined as increase of ≥1 Geometric Centre (median radiotracer position at each time [small bowel = 1, toilet = 6]). RESULTS: Forty-six subjects completed the trial, 34 had NTS after stimulation (21 M, 8-17 years, mean 11.3 years; symptoms >9 years). Active stimulation increased transit in >50% versus only 25% with sham (p = 0.04). Seventeen children also had UGD. In children with STC and either normal upper GI motility (NUGM) and UGD, NTS improved slightly after 1 month (57 vs. 60%; p = 0.9) and more after 2 months (88 vs. 40%; p = 0.07). However, mean transit rate significantly increased with NUGM, but not UGD (5.0 ± 0.2: 3.6 ± 0.6, p < 0.01). CONCLUSION: Transcutaneous electrical stimulation was beneficial for STC, with response weakly associated with UGD. As measured by NTS, STC children with NUGM responded slightly more, but with significantly greater increased transit compared to those with UGD. Higher numbers are needed to determine if the difference is important.

Trunk strength and mobility changes in children with slow transit constipation.

BACKGROUND AND AIM: It appears that there are no published reports on childhood slow transit constipation (STC) that have considered the state of the musculoskeletal components of the trunk in these children. The present study aimed to determine whether children with STC have different trunk musculoskeletal characteristics that might be related to their defecation difficulties, compared to controls. METHODS: With the aid of computer-analyzed photographs and clinical testing, 41 children with STC and 41 age-matched controls were examined for Marfanoid features, sitting posture, spinal joint mobility and trunk muscle strength. The latter was assessed by measuring maximum voluntary abdominal bulging and retraction in sitting, and active trunk extension in prone-lying. Levels of general exercise and sedentary activities were evaluated by questionnaire. RESULTS: STC subjects were more slumped in relaxed sitting (P < or = 0.001), less able to bulge (P < or = 0.03) and less able to actively extend the trunk (P = 0.02) compared to controls. All subjects sat more erect during abdominal bulging (P < or = 0.03). CONCLUSION: The results show that STC children have reduced trunk control and posture, which indicates that clinicians should include training of trunk muscles and correction of sitting posture. There was no evidence that children with STC exercised less than the controls.

Improvement of quality of life in children with slow transit constipation after treatment with transcutaneous electrical stimulation.

BACKGROUND: Slow transit constipation (STC) causes intractable symptoms not responsive to medical treatment. Children have irregular bowel motions, colicky abdominal pain, and frequent soiling. Transcutaneous electrical stimulation using interferential current (interferential therapy [IFT]) is a novel treatment of STC. This study assessed quality of life (QOL) in STC children before and after IFT treatment. METHODS: Eligible STC children were randomized to receive either real or placebo IFT (12 sessions for 4 weeks). Questionnaires (Pediatric Quality of Life Inventory) were administered before and 6 weeks after treatment, with parallel parent and child self-report scales. Higher scores indicate better QOL. Holschneider and Templeton scores were also obtained. The QOL scores were compared using paired t tests. RESULTS: Thirty-three children (21 male), with a mean age of 11.8 years (range, 7.4-16.5 years), were recruited; 16 received real IFT. Child-perceived QOL was improved after real IFT compared with baseline (81.1 vs 72.9, P = .005) but not after placebo IFT (78.1 vs 74.9, P = .120). The Holschneider score improved after real IFT (10 vs 8, P = .015) but not after placebo IFT (9 vs 8, P = .112). Parentally perceived QOL was similar after real IFT (70.1 vs 70.3, P = .927) and placebo IFT (70.2 vs 69.8, P = .899). There were no differences in Templeton scores. CONCLUSION: Interferential therapy is a novel therapy for children with STC that improves their self-perceived QOL.

Standard medical therapies do not alter colonic transit time in children with treatment-resistant slow-transit constipation.

BACKGROUND: Slow transit constipation (STC) is a form of chronic constipation characterised by prolonged passage of faecal matter through the colon. It is diagnosed by demonstrating delayed colonic transit on gastrointestinal transit studies. Traditionally, radio-opaque marker studies are performed. Recently, radioisotope nuclear transit studies (NTS) have been used in our centre to assess gastrointestinal transit time. This study aimed to evaluate if there are changes in colonic transit in STC children resistant to standard medical treatment over a prolonged period. METHODS: Children with STC resistant to standard medical therapy for > or =2 years who had undergone two separate NTS to assess their colonic transit (where the first study had identified slow colonic transit without anorectal retention) were identified after ethical approval. The geometric centre (GC) of radioisotope activity at 6, 24, 30 and 48 h was compared in the two transit studies to determine if changes occurred. RESULTS: Seven children (4 males) with proven STC resistant to standard medical therapy and two transit studies performed at different times were identified. Mean age was 7.0 years (5.4-10.8 years) at first study, and 11.4 years (9.7-14.2 years) at second study, with a mean of 4.4 years (1-8.5 years) between studies. There was no significant difference in colonic transit at any timepoint in the two tests (paired t test). CONCLUSIONS: We conclude that nuclear transit studies are reproducible in assessing slow colonic transit in children with treatment-resistant STC and demonstrate that conventional medical treatment over many years has no effect on underlying colonic motility.

Slow-transit constipation in children: our experience.

Constipation is a common problem in children, with childhood prevalence estimated at between 1 and 30%. It accounts for a significant percentage of referrals to paediatricians and paediatric gastroenterologists. It commonly runs in families, suggesting either an underlying genetic predisposition or common environmental factors, such as dietary exposure. The peak age for presentation of constipation is shortly after toilet training, when passage of hard stools can cause pain on defecation, which then triggers holding-on behaviour in the child. At the time of the next call to stool the toddler may try to prevent defecation by contraction of the pelvic floor muscles and anal sphincter. Unless the holding-on behaviour is quickly corrected by interventions to soften faeces and prevent further pain, the constipation can very rapidly become severe and chronic. Until recently, this mechanism was thought to be the only significant primary cause of constipation in childhood. In this review, we will summarise recent evidence to suggest that severe chronic constipation in children may also be due to slowed colonic transit.

Decreased colonic transit time after transcutaneous interferential electrical stimulation in children with slow transit constipation.

PURPOSE: Idiopathic slow transit constipation (STC) describes a clinical syndrome characterised by intractable constipation. It is diagnosed by demonstrating delayed colonic transit on nuclear transit studies (NTS). A possible new treatment is interferential therapy (IFT), which is a form of electrical stimulation that involves the transcutaneous application of electrical current. This study aimed to ascertain the effect of IFT on colonic transit time. METHODS: Children with STC diagnosed by NTS were randomised to receive either 12 real or placebo IFT sessions for a 4-week period. After a 2-month break, they all received 12 real IFT sessions-again for a 4-week period. A NTS was repeated 6 to 8 weeks after cessation of each treatment period where able. Geometric centres (GCs) of activity were calculated for all studies at 6, 24, 30, and 48 hours. Pretreatment and posttreatment GCs were compared by statistical parametric analysis (paired t test). RESULTS: Thirty-one pretreatment, 22 postreal IFT, and 8 postplacebo IFT studies were identified in 26 children (mean age, 12.7 years; 16 male). Colonic transit was significantly faster in children given real treatment when compared to their pretreatment NTS at 24 (mean CG, 2.39 vs 3.04; P < or = .0001), 30 (mean GC, 2.79 vs 3.47; P = .0039), and 48 (mean GC, 3.34 vs 4.32; P = .0001) hours. By contrast, those children who received placebo IFT had no significant change in colonic transit. CONCLUSIONS: Transcutaneous electrical stimulation with interferential therapy can significantly speed up colonic transit in children with slow transit constipation.

Connective tissue disorder--a new subgroup of boys with slow transit constipation?

PURPOSE: Slow transit constipation (STC) is a form of chronic constipation, with delayed colonic passage of stool. Possible etiologies include reduced neurotransmitter levels, reduced interstitial cells of Cajal density, or a disorder of connective tissue (CT) synthesis. A common CT disorder is generalized joint hypermobility (GJH). This study aimed to investigate whether there was a greater prevalence of GJH among patients with STC than controls. METHODS: Children (aged 7-17) diagnosed with STC by radio/nuclear transit study were recruited from outpatient clinics. Controls (no history of constipation) were recruited from outpatient clinics and a scout jamboree. Hypermobility was assessed using the Beighton score (4 or more = hypermobile). This project received ethical approval by the human research ethics committee. RESULTS: Thirty-nine STC subjects and 41 controls were measured. Of 39 STC subjects, 15 (38%) were hypermobile, compared to 8 (20%) of 41 controls (P = .06). Analyzed by gender, 10 (38%) of 26 STC males and 1 (4%) of 23 control males were hypermobile (P < .01). CONCLUSIONS: These results show that GJH is higher in STC children, particularly males, suggesting that a disorder of CT synthesis plays a role in the etiology of STC. Further research is required to ascertain the nature of any relationship and how this knowledge may aid our understanding and treatment of STC.

Quality of life in children with slow transit constipation.

BACKGROUND: Slow transit constipation (STC) causes intractable symptoms not readily responsive to laxatives, diet, or life-style changes. Children with STC have irregular bowel motions associated with colicky abdominal pain and frequent uncontrollable soiling. This study assessed the physical and psychosocial quality of life (QOL) in children with long-standing (> or =2 years) STC vs healthy controls. METHODS: Children (aged 8-18) were recruited from gastrointestinal and surgical clinics and a Scout Jamboree. After informed consent was obtained, the questionnaire (Pediatric Quality of Life Inventory) was administered. This consists of parallel child and parent self-report scales encompassing physical functioning, emotional functioning, social functioning, and school functioning. Higher scores indicate better QOL. P value less than .05 was considered statistically significant. RESULTS: In 51 children with STC (mean, 11.5 years; male/female, 2:1) and 79 controls (mean, 12.1 years; male/female, 1.9:1), Pediatric Quality of Life Inventory QOL score was significantly lower in the STC group (72.90 vs 85.99; P < .0001). In addition, parents of children with STC reported a significantly lower QOL score than their child compared with the child's own report (64.43 vs 72.90; P = .0034). Parents of controls did not (84.25 vs 85.99; P = .12). CONCLUSIONS: Slow transit constipation is a debilitating condition affecting both physical and emotional functioning in children. Parental perception of QOL is significantly worse, highlighting the considerable family impact of constipation and uncontrollable soiling.
