It has been suggested that the addition of behavioral interventions to laxative therapy improves continence in children with functional fecal incontinence associated with constipation. Our aim was to evaluate the clinical effectiveness of behavioral therapy with laxatives compared with conventional treatment in treating functional constipation in childhood.
                In this randomized, controlled trial conducted in a tertiary hospital in The Netherlands, 134 children aged 4 to 18 years with functional constipation were randomly assigned to 22 weeks (12 visits) of either behavioral therapy or conventional treatment. Primary outcomes were defecation frequency, fecal incontinence frequency, and success rate. Success was defined as defecation frequency of > or = 3 times per week and fecal incontinence frequency of < or = 1 times per 2 weeks irrespective of laxative use. Secondary outcomes were stool-withholding behavior and behavior problems. Outcomes were evaluated at the end of treatment and at 6-months follow-up. All of the analyses were done by intention to treat.
                Defecation frequency was significantly higher for conventional treatment. Fecal incontinence frequency showed no difference between treatments. After 22 weeks, success rates did not differ between conventional treatment and behavioral therapy (respectively, 62.3% and 51.5%), nor did it differ at 6 months of follow-up (respectively, 57.3% and 42.3%). The proportion of children withholding stools was not different between interventions. At follow-up, the proportion of children with behavior problems was significantly smaller for behavioral therapy (11.7% vs 29.2%).
                Behavioral therapy with laxatives has no advantage over conventional treatment in treating childhood constipation. However, when behavior problems are present, behavioral therapy or referral to mental health services should be considered. To compare short- and long-term effectiveness of three additive treatment protocols in children experiencing chronic encopresis.
                Children, 6 to 15 years of age, who experienced at least weekly fecal soiling for 6 months or longer were eligible for the study. Children were randomly assigned to a group that received intensive medical therapy (IMT), a group that received intensive medical therapy plus a behavior management program called enhanced toilet training (ETT), or a group that received intensive medical therapy with enhanced toilet training and external anal sphincter electromyographic biofeedback (BF). Data concerning toileting habits were collected for 14 consecutive days before an initial visit, and at 3, 6, and 12 months after initiation of therapy. All data were collected using a computerized voice-mail system that telephoned the families each day. At 12 months, children were classified as significantly improved (reduction in soiling, P < 0.001) or cured (<one fecal accident in 2 weeks).
                Eighty-seven children participated in the study, 72 boys and 15 girls. Mean age at enrollment was 8.6 +/- 2.0 years, and mean duration of symptoms was 58.2 +/- 38.5 months. At 12 months, the cure rates for the IMM, ETT, and BF groups were 36, 48, and 39, respectively (not significant). The improvement rates for these three groups were 45, 78, and 54, respectively (P < 0.05). These results were very stable over time (r > 0.90, P < 0.001 in each case). Response to treatment during the first 2 weeks of therapy was highly predictive of outcome at 3, 6, and 12 months (P < 0.0001). Children in the ETT group used less laxative medication (P < 0.04) and required fewer treatment contacts (P = 0.08) than children in the IMM group. All three treatments resulted in significant increases in daily bowel movements passed in the toilet and self-initiated toileting, and resulted in decreases in average daily soiling at 3, 6, and 12 months (P < 0.05).
                Enhanced toilet training is somewhat more effective in treating childhood encopresis than either intensive medical therapy or anal sphincter biofeedback therapy. Although similar total cure rates at 1 year can be expected with these three forms of therapy, enhanced toilet training results in statistically significant decreases in the daily frequency of soiling for the greatest number of children. This study evaluated the efficacy of biofeedback training for fecal in continence in patients with myelomeningocele. 12 patients were randomized to receive conventional treatment alone, or in conjunction with biofeedback. Anorectal manometric functions were evaluated before and after treatment, six and 12 months later. 16 control children were also studied. Three of eight patients in the biofeedback group and three of the four given conventional treatment alone reported greater than or equal to 75 per cent improvement in frequency of soiling 12 months later. Biofeedback training did not improve anal squeeze, rectal sensation or continence of rectal infused saline. The number of patients who improved in both treatment groups was not different. Children with encopresis (costiveness) have a social problem, and (BFB) offers them a valid therapeutic alternative. The present prospective study compares the advantages of this technique with conventional treatment in 21 patients, with average ages of 10.13 and 8.54 years in each group. The patients were studied by clinical, manometric and electromyographic parameters. Those treated with BFB showed clinical improvement, with manometric significant enhancement (p < 0.001) of the percentage of internal anal sphincter (IAE) relaxation, relaxation interval of the IAE and rectal sensation threshold (RST), on the other hand, patients treated by conventional therapy only improved the RST (p < 0.01). Biofeedback seems useful in the treatment of the child with encopresis. To determine whether the combination of laxative treatment and biofeedback therapy (BF) is more effective for management of functional nonretentive fecal soiling than biofeedback therapy alone.
                In a prospective nonblinded study, 48 children were randomized in 2 groups: treatment with oral laxatives (LAX) and 5 sessions of BF (BF + LAX) or 5 sessions of BF alone (BF) during a treatment intervention period of 7 weeks. Biofeedback was performed with perfused manometry catheters and rectal balloon distension. Training focused on awareness of balloon distension and instruction in correct defecation dynamics. Successful treatment was defined as <1 encopresis episode per 2 weeks.
                At the end of the intervention period, the number of encopresis episodes was significantly decreased in both groups: from 7 (2 to 24) to 2 (0 to 17) in the BF group and from 7 (3 to 25) to 2 (0 to 14) in the BF + LAX group. However, children given BF alone had significantly higher success rates than children treated with BF and additional oral laxatives (44% to 11%).
                There is no additional effect of laxative treatment in functional nonretentive fecal soiling. Children treated with BF in combination with laxatives showed a significantly lower success percentage compared with those treated with BF alone. These results suggest that children with functional nonretentive fecal soiling should be treated differently from children with constipation and encopresis. Approximately 50% of constipated children contract rather than relax the external sphincter complex during a defecation attempt. Although biofeedback training (BF) is able to change this defecation behavior, there is no additional effect of BF to conventional treatment (CT) on clinical outcome compared with CT alone. It has been postulated that the absence of a significant difference between these 2 treatment options might be because of a therapeutic, "demystifying" effect of performing anorectal manometry in conventionally treated children, necessary to obtain basal manometric data. The objective of this prospective, controlled, randomized study was to evaluate the effect of CT with 2 anorectal manometry sessions compared with CT alone (dietary advice, diary, toilet training, oral laxatives, and enemas) on clinical outcome.
                A total of 212 constipated children (143 boys) who were visiting a referral pediatric gastroenterologic practice were randomized prospectively to CT alone (115 patients) or to CT combined with 2 manometry sessions (CTM; 97 patients). Patients were included in the study when they fulfilled at least 2 of the 4 following criteria: stool frequency fewer than 3 per week, 2 or more soiling and/or encopresis episodes per week, periodic passage of very large amounts of stool every 7 to 30 days, or a palpable rectal or abdominal fecal mass. CT comprises dietary advice, a daily diary, toilet training, and oral laxative treatment preceded by rectal disimpaction with enemas on 3 consecutive days. During both manometries, the child and the parent could watch the tracing on the computer screen. No explanation was given to either the child or the parents during the procedure. When the procedure was finished, the tracings were clarified. Successful treatment was defined as a defecation frequency of 3 or more per week and fewer than 1 soiling/encopresis episode per 2 weeks and no use of laxatives.
                Only 4 and 2 children from the CT and CTM groups showed no soiling and/or encopresis, whereas 76% and 65%, respectively, reported the periodic passage of large stools. In 26% and 30% of the patients, a rectal scybalum was found on physical examination. The success rates at 6, 26, 52, and 104 weeks' follow-up were 4%, 24%, 32%, and 43% and 7%, 22%, 30%, and 35% in the CT and CTM group, respectively. No significant difference in success percentage was observed between the 2 groups at any time of follow-up with relative risks (CT/CTM) and 95% confidence intervals, respectively, of 0.55 (0.16-1.89), 1.13 (0.67-1.89), 1.07 (0.69-1.65), and 1.23 (0.81-1.85). A significant increase in defecation frequency was observed between the first (intake) and second visits, which was sustained at all subsequent visits and stages of follow-up in both groups (not significant). Also in relation to the first visit, a significant decrease in encopresis episodes was shown and a further slow but significant decrease at 52 weeks of follow-up in both groups. The manometric data obtained from the CTM group showed a low percentage of children with normal defecation dynamics, namely 28%, which (significantly) increased to 38% at the last manometry.
                Anorectal manometry combined with CT compared with CT alone did not result in higher success rates in chronically constipated children. Therefore, anorectal manometry has no additional demystifying or educational effect on clinical outcome in chronically constipated children. This observation together with the observation in the current and previous studies that no correlation was found between (achievement of) normal defecation dynamics and success and that no relation was observed between volume of urge or critical volume and success leaves no diagnostic or therapeutic role for anorectal manometry in chronic constipated children, except its use as a diagnostic test to exclude Hirschsprung's disease. A simple CT is successful in 30% of severely constipated children who are referred to a tertiary hospital, underscoring the importance of long-lasting and adequate laxative treatment. Fecal incontinence is a socially disabling symptom for which rectosphincteric biofeedback has been reported to be dramatically effective. The most commonly employed biofeedback procedure incorporates three separate and potentially effective components: exercise of the external sphincter muscle, training in discrimination of rectal sensations, and training synchrony of the internal and external sphincter responses. This paper reports the results of single case experiments employed with eight incontinent patients to examine the contributions of each of these components. All eight patients improved, but only one required the biofeedback procedure as it was originally described. Three responded to sensory discrimination training, one to exercise training, and one to the training of synchronous sphincteric responses; three recovered independently of the effects of biofeedback. Despite the achievement of continence, the rectosphincteric reflexes following treatment continued to be abnormal in every case. These findings suggest that the character of the external sphincter response to rectal distension is an unreliable index of sphincter function and that exercise and sensory discrimination training procedures are effective for some cases of fecal incontinence. The purpose of this study was to determine whether biofeedback benefits children with dyssynergic defecation and constipation/encopresis, and whether home biofeedback improves long-term outcomes. Thirty-six patients with chronic constipation who had failed at least 6 months of conventional treatment and demonstrated dyssynergic defecation at anorectal manometry were randomized to biofeedback in the laboratory alone (group 1, n=24) or in the laboratory and at home (group 2, n=12) and followed up at 2, 4, and a mean of 44 months. Thirty patients were available for long-term follow-up. Bowel movements increased in all from a mean of 1.4/week to 5.1, 5.8, and 5.1 per week at 2 months, 4 months, and long-term, respectively (p < or = 0.001). Soiling decreased in all from a mean of 5.5/week to 0.6, 0.1, and 1 per week at 2 months, 4 months, and long-term, respectively (p < or = 0.001). Laxative use decreased from a mean of 4.1 days/week to 0.6, 0.3, and 0.7 per week at 2 months, 4 months, and long-term, respectively (p < or = 0.001). Twenty-seven of 30 parents ranked their satisfaction a mean of 2.2 (range 1-excellent to 3-good). There were no significant differences in outcomes between the laboratory alone group and the laboratory plus home group. Biofeedback is beneficial for some children with chronic constipation and dyssynergic defecation. Supplemental home biofeedback does not improve long-term outcomes. Simple, incentive based behaviour modification, with or without a modest programme of psychotherapy involving outpatient visits every four to six weeks, seems to be associated with a useful cure rate in children with lower bowel function disorders. Appreciable social disadvantage seems to be the most important factor mitigating against a successful outcome, associated with non-compliance with treatment. Failure to respond to treatment was associated with important psychological problems. These were more common in the socially disadvantaged groups. Children from satisfactory social backgrounds who have lower bowl disturbances can be effectively treated by fairly simple programmes. More elaborate and expensive strategies should be reserved for those whose psychosocial circumstances make it possible to predict a less satisfactory outcome. Paradoxical external anal sphincter contraction during attempted defecation (anismus) is thought to be an important contributor to chronic faecal retention and encopresis in children. Biofeedback training can be used to teach children to abolish this abnormal contraction.
                A randomised controlled trial in medical treatment resistant and/or treatment dependent children with anismus using surface electromyographic (EMG) biofeedback training to determine whether such training produces sustained faecal continence. Up to four sessions of biofeedback training were conducted at weekly intervals for each patient. Anorectal manometry was performed before randomisation and six months later. Parents of patients completed the "child behaviour checklist" (CBCL) before randomisation and at follow up.
                Sixty eight children underwent anorectal manometry and EMG. Of these, 29 had anismus (ages 4-14 years) and were randomised to either EMG biofeedback training and conventional medical treatment (BFT) (n = 14) or to conventional medical treatment alone (n = 15). All but one child were able to learn relaxation of the external anal sphincter on attempted defecation. At six months' follow up, laxative free remission had been sustained in two of 14 patients in the BFT group and in two of 15 controls (95% confidence interval (CI) on difference, -24% to 26%). Remission or improvement occurred in four of 14 patients in the BFT group and six of 15 controls (95% CI on difference, -46% to 23%). Of subjects available for repeat anorectal manometry and EMG at six months, six of 13 in the BFT group still demonstrated anismus v 11 of 13 controls (95% CI on difference, -75% to -1%). Of the four patients in full remission at six months, only one (in the BFT group) did not exhibit anismus. Rectal hyposensitivity was not associated with remission or improvement in either of the groups. Mean CBCL total behaviour problem scores were not significantly different between the BFT and control groups, but there was a significant improvement in CBCL school scale scores in the BFT group, and this improvement was significantly greater than that seen in the control group.
                The result of this study, together with those reported in other controlled trials, argues against using biofeedback training in children with encopresis. In order to evaluate the efficacy of biofeedback for childhood encopresis, 50 children with encopresis were prospectively studied and randomized to receive biofeedback (B) or mineral oil therapy (M). Specificity of biofeedback was also evaluated by comparing outcomes of both regimens in children with normal (n = 32) and abnormal (n = 18) defecation patterns. Using a single blinded design, there were no significant differences in clinical outcomes between the 24 children receiving B and the 26 children receiving M at 3, 6, and 12 months. However, at 12 months six of nine children with abnormal defecation patterns were in remission or markedly improved after receiving B, compared to only three of nine children receiving M. In contrast, children with normal patterns appeared to respond better to M than did those receiving B (71 vs. 40% at 12 months). Biofeedback appears to warrant further evaluation in children with encopresis and abnormal defecation patterns. Chronic constipation is a common disorder in childhood. The underlying mechanisms responsible for chronic constipation remain unknown. Conventional methods of treatment often fail to produce satisfactory results. Favorable effects of biofeedback treatment for constipation have been suggested, however, with variable results reported in the literature. The main aim of the study was to evaluate biofeedback versus conventional therapeutic protocol in the treatment of chronic constipation over a short period of time (3 months). Forty-nine children with chronic idiopathic constipation, 24 allocated to conventional and 25 to biofeedback therapy were included in the study. Thorough history data on bowel function and symptoms, anorectal status and manometric testing were collected before and after treatment. Follow up consisted of a structured interview. Mean age was 94 and 92 months in the children treated by the conventional and biofeedback method, respectively. The initial prevalence of abnormal defecation dynamics was 58% and 56% in the group children allocated to conventional and biofeedback therapy, respectively. The difference was not statistically significant. After the treatment, the values of rectal sensation threshold, critical volume, and recto-anal inhibitory reflex volume were significantly higher, and the prevalence of abnormal defecation dynamics was significantly lower in the group on biofeedback therapy. Biofeedback is an effective method of treatment for chronic constipation in children in short term. Therapeutic results are especially favorable in the recovery of abnormal anorectal dynamics and manometric parameters. There is no clear evidence for long-term benefits of biofeedback therapy. Because abnormal defaecation dynamics, which can be modified by biofeedback, are considered to be the underlying problem in constipation, biofeedback training may be a useful treatment for constipation. This treatment has mainly been studied in uncontrolled trials. We evaluated defaecation dynamics and clinical outcome in chronically constipated children in a randomised study comparing conventional treatment and conventional treatment with biofeedback training.
                Patients, 5 to 16 years old, were referred to the Academic Medical Center in Amsterdam by general practitioners, school doctors, paediatricians, and psychiatrists. They had to fulfil at least two of four criteria for paediatric constipation and were included if they had been treated medically for at least one month before randomisation. Patients had a medical history, abdominal and rectal examination, and anorectal manometry at the start and end of the 6-week intervention period. The conventional group received laxative treatment with additional dietary advice, toilet training, and maintenance of a diary of bowel habits. The biofeedback group received the same conventional treatment and additionally five biofeedback training sessions. During the first 3 weeks, patients visited the outpatient clinic weekly; two subsequent visits were twice monthly.
                94 patients were randomised to conventional treatment (CT) and 98 to conventional treatment with additional biofeedback training (CT+BF). Normal defaecation dynamics increased in the CT group from 41% to 52% (not significant) and in the CT+BF group from 38% to 86% (p = 0.001). At 6 weeks, more patients in the CT+BF group showed normal defaecation dynamics, compared to the CT group (p < 0.001). This result was unaltered by controlling for baseline status in a logistic regression model. At 1 year, successful treatment (defaecation frequency > or = 3/week, soiling and/or encopresis < 2/month, and no laxatives) was accomplished in 59% of the CT and 50% of the CT+BF group (p = 0.24). The results were maintained after 1 1/2 years follow-up. No association was found between achievement of normal defaecation dynamics and clinical outcome.
                Additional biofeedback training compared to conventional therapy did not result in higher success rates in chronically constipated children. Furthermore, achievement of normal defaecation dynamics was not associated with success: abnormal defaecation dynamics seem not to play a crucial role in the pathogenesis of childhood constipation. Intensive conventional laxative treatment should remain the first choice in chronically constipated children. To evaluate biofeedback training in children with encopresis and the effect on psychosocial function.
                Prospective controlled randomised study. PATIENT INTERVENTIONS: A multimodal treatment of six weeks. Children were randomised into two groups. Each group received dietary and toilet advice, enemas, oral laxatives, and anorectal manometry. One group also received five biofeedback training sessions.
                Successful treatment was defined as less than two episodes of encopresis, regular bowel movements, and no laxatives. Psychosocial function after treatment was assessed using the Child Behaviour Checklist.
                Children given laxatives and biofeedback training had higher success rates than those who received laxatives alone (39% v 19%) at the end of the intervention period. At 12 and 18 months, however, approximately 50% of children in each group were successfully treated. Abnormal behaviour scores were initially observed in 35% of children. Most children had improved behaviour scores six months after treatment. Children with an initial abnormal behaviour score who were successfully treated had a significant improvement in their behavioural profiles.
                Biofeedback training had no additional effect on the success rate or behaviour scores. Psychosocial problems are present in a subgroup of children with encopresis. The relation between successful treatment and improvement in behavioural function supports the idea that encopresis has an aetiological role in the occurrence and maintenance of behavioural problems in children with encopresis. About 2/3 of constipated children present anal-rectal dyssynergy (ARD) with paradoxical contraction of the external anal sphincter (EAS) during defecation.
                The aim of our study was to answer the question whether additional treatment with biofeedback training (BF) is more effective than traditional treatment. MATERIALS, METHODS: We assessed chronically constipated children who fulfilled the criteria of ARD: recto-sigmoid transit time in Hinton's test with radio-paque markers at least 28.8 h, paradoxical EAS contraction during defecation trials (anorectal manometry). The study included 22 constipated children (16 boys and 6 girls), aged 5 to 14 years (mean 8.1 +/- SD 2.8). Children were randomly divided in two groups. In group I at the start of the study children had four day-by-day sessions of BF training based on the anorectal manometry and the surface EMG. Children from group II received only traditional treatment. The follow-up was 6 months. Improvement was estimated based on manometric data, number and quality of stools.
                In the group I after one month, more manometric parameters, significantly improved as compared to the II group. During the observation period the number of stools increased and their quality improved in both groups. There was no statistically significant difference between the groups in terms of the above mentioned symptoms.
                Treatment with BF can improve rectal sensation and particularly defecation dynamics, faster than the traditional method. There is no significant effect of additional BF treatment on such objective symptoms as the number and quality of stools. Primary faecal incontinence (encopresis) in children is usually treated with laxative medication and a behaviour modification programme aimed at promoting regular toileting, but the effectiveness of laxatives has never been adequately investigated. 169 children with encopresis and evidence of stool on plain abdominal radiograph were randomly allocated to receive multimodal (MM) therapy (laxatives plus behaviour modification; n = 83) or behaviour modification alone (BM; n = 86). Mean (SD) follow-up was 55.1 (27.0) weeks and 56.7 (32.0) weeks, respectively. By 12 months' follow-up 42 (51%) of the MM group and 31 (36%) of the BM group (p = 0.079) had achieved remission (at least one 4 week period with no soiling episodes) and 52 (63%) vs 37 (43%) (p = 0.016) had achieved at least partial remission (soiling no more than once a week). MM subjects achieved remission significantly sooner than BM subjects, and the difference in the Kaplan-Meier remission curves was most striking in the first 30 weeks of follow-up (p = 0.012). The patterns of compliance with toileting in the treatment groups were almost identical, although about 1 in 8 children overall did not comply with the sitting programme. After exclusion of the 24 poor compliers, there was no significant difference between BM and MM groups. This study shows a clear advantage overall for the use of laxative medication, although the benefit may not be as great for children who are able to maintain regular toileting. This study evaluated the benefits of enhanced toilet training delivered through the Internet for children with encopresis. Twenty-four children with encopresis were randomly assigned to the Internet intervention group (Web) or no Internet intervention group (No-Web). All participants continued to receive routine care from their primary care physician. The Web participants demonstrated greater improvements in terms of reduced fecal soiling, increased defecation in the toilet, and increased unprompted trips to the toilet (ps<.02). Both groups demonstrated similar improvements in knowledge and toileting behaviors. Internet interventions may be an effective way of delivering sophisticated behavioral interventions to a large and dispersed population in a convenient format. To determine whether outcome in chronically constipated and encopretic children with abnormal defecation dynamics could be improved with biofeedback training, we randomly assigned patients, 5 to 16 years of age, to receive conventional treatment alone (n = 19) or conventional plus biofeedback treatment (n = 22) and evaluated physiologic outcome at 7 months and clinical outcome at 7 and 12 months. Eighty-six percent of patients learned normal defecation dynamics with up to six biofeedback sessions. At 7 months, 13% of conventionally treated and 77% of biofeedback-treated patients had normal defecation dynamics (p less than 0.01); one conventionally treated (5%) and 12 biofeedback-treated patients (55%) had recovered (p less than 0.01). Learning normal defecation dynamics was correlated with clinical recovery (p less than 0.01). At 7 months, 11% of patients with normal defecation dynamics after biofeedback treatment had abnormal defecation dynamics, and 71% of the biofeedback-treated patients with normal defecation dynamics recovered. At 12 months, 16% of conventionally treated and 50% of biofeedback-treated patients had recovered (p less than 0.05). Balloon defecation did not improve significantly in those who learned normal defecation dynamics. Therefore the ability to defecate balloons is apparently not dependent on the normal function of the external and sphincter and pelvic floor muscles alone. Biofeedback treatment is complementary to a good conventional therapeutic regimen in patients with abnormal defecation dynamics. A double-blind randomly controlled trial of one particular laxative, Senokot, used in moderate dosage, was carried out on a group of 40 children with severe and persistent soiling and often with a history of faecal retention. Significant improvement occurred following three months of outpatient treatment using a behavioural approach and either Senokot, placebo or no medication. However, there was no evidence either during the trial or subsequently when Senokot was employed to supplement behavioural treatment in every child who continued with therapy that this laxative contributed in any way to relieving the problem in this group of cases.
There is no evidence that biofeedback training adds any benefit to conventional treatment in the management of functional faecal incontinence in children. There was not enough evidence on which to assess the effects of biofeedback for the management of organic faecal incontinence. There is some evidence that behavioural interventions plus laxative therapy, rather than laxative therapy alone, improves continence in children with functional faecal incontinence associated with constipation.
