Psychosocial factors impacting antegrade continence enema outcomes in pediatric patients.

BACKGROUND: Children with constipation and encopresis are often treated with medication and behavioral approaches. When constipation persists, surgical interventions such as antegrade continence enema (ACE) procedures are considered. Many children benefit from these procedures; however, some children continue to have incontinence, experience complications, or discontinue the use of the ACE stoma. There is some evidence in the literature to indicate that psychosocial factors can have an impact on ACE outcomes; however, standardized biopsychosocial guidelines related to ACE candidacy and surgery do not currently exist. PURPOSE: The purpose of this review is to summarize the research to date on psychosocial factors related to ACE treatment outcomes and complications. Identifying what is known and what limitations remain can support future research to inform development of guidelines for pre-procedure evaluations. Psychosocial pre-procedure evaluations could help to inform eligibility for the procedure as well as interventions to enhance outcomes for children at increased risk for poor outcomes or complications from ACE. Age, psychiatric symptoms, and adherence to the ACE flush regimen were some of the factors identified in the literature as impacting ACE outcomes; however, there is limited research in this area.

Comparing quality of life improvement after antegrade continence enema (ACE) therapy for patients with organic and functional constipation / encopresis.

BACKGROUND: We compared patient- and family-reported overall and stool-related quality of life (QoL) before and after an antegrade continence enema (ACE) procedure (cecostomy tube insertion) for refractory chronic constipation or fecal incontinence (CCFI). We hypothesized that patients with functional diagnoses experience similar improvements in QoL compared to those with organic diagnoses. METHODS: This is a cross-sectional study of patients undergoing cecostomy tube insertion for CCFI at a tertiary pediatric hospital from 2012 to 2019. Patients and/or primary caregivers completed validated stooling and overall QoL surveys based on three time points: before surgery, three months after surgery, and at the time of survey / date of last follow-up. Repeated measures analyses compared scores over time between subjects and within the diagnostic groups. RESULTS: The response rate was 65% (22/34 patients, 12 organic and 10 functional diagnoses). Mean age was 8.3 years and 32% of the participants were female. Organic diagnoses were: spina bifida (6), anorectal malformation (5), and Hirschsprung Disease (1). There was substantial improvement in stool-related and overall QoL at three months post-ACE procedure (both p<0.001) for all patients; both scores continued to improve significantly until the date of last follow-up (median 4.1 years, IQR 2.3-5.6, p<0.001). There was no statistically significant difference in scores between patients with organic and functional diagnoses. CONCLUSIONS: Caregivers perceive a significant, sustainable improvement in stooling habits and QoL following ACE therapy. The improvement is comparable between patients with a functional diagnosis and those with an underlying organic reason for their CCFI.

Use of expedited post-operative protocol for children undergoing appendicostomy reduces length of hospitalization.

BACKGROUND: An appendicostomy (ACE) is a surgical option for antegrade enemas in children with severe constipation and/or fecal incontinence who have failed medical management.  In 2019, we initiated an expedited post-operative protocol and sought to examine our short-term outcomes compared with our historical cohort. METHODS: A retrospective review was performed of all children undergoing ACE between 2017 and 2020. Children were excluded if they underwent an associated procedure (e.g. colon resection). Patients were divided into two cohorts: historical cohort (2017-2018, Group A) and the expedited protocol (2019 to present, Group B). The primary outcome was length of stay. RESULTS: 30 patients met inclusion (Group A = 16, Group B = 14). The most common indications for ACE were constipation (50%) and constipation or fecal incontinence associated with anorectal malformation (43%). Group B experienced a decreased length of stay (1 vs 3 days, P = 0.001) without differences in 30-day surgical site infection (7.1% vs 18.8%, p = 0.61) or unplanned visit (15.4% vs 18.8%, p = 1.0). Group B had a higher prevalence of MiniACE® button placed through the appendix vs. Malone (42.8% vs 12.5%, p = 0.10). CONCLUSIONS: Our expedited post-op protocol decreased length of stay without other significant adverse clinical sequelae. LEVEL OF EVIDENCE: Retrospective Comparative Study, Level III.

Long-term outcomes of antegrade continence enema in children with chronic encopresis and incontinence: what is the optimal flush to use?

PURPOSE: Severe constipation and encopresis are significant problems in the pediatric population. Medical management succeeds in 50-70%; however, surgical considerations are necessary for the remainder such as the antegrade continence enema (ACE). The purpose of this study is to assess the long-term outcomes following the ACE procedure. METHODS: All patients undergoing an ACE over a 14-year period were included. Data on clinical conditions, treatments, and outcomes were collected. A successful outcome was defined as remaining clean with ≤ 1 accident per week. Comparative data were analyzed using the Fisher's exact test, Mann-Whitney U test, or Student's t test. RESULTS: There were 42 ACE patients, and overall, 79% had improvement in their bowel regimens. Encopresis rates decreased from 79 to 5% (P < 0.001). Admissions for cleanouts decreased from 52 to 19% (P = 0.003). All cases of Hirschsprung's, functional constipation and spina bifida were successful. Rates of success varied for other diseases such as slow-transit constipation (60%) and cerebral palsy (33%). A majority (85%) required a change in the enema composition for improvement. CONCLUSION: In our study, ACE reduced soiling, constipation, and need for fecal disimpaction. Higher volume saline flushes used once a day was the optimal solution and most preferred option. LEVEL OF EVIDENCE: Level 4 (retrospective case series or cohort).

Constipation: Beyond the Old Paradigms.

Constipation is a common problem in children. Although most children respond to conventional treatment, symptoms persist in a minority. For children with refractory constipation, anorectal and colonic manometry testing can identify a rectal evacuation disorder or colonic motility disorder and guide subsequent management. Novel medications used in adults with constipation are beginning to be used in children, with promising results. Biofeedback therapy and anal sphincter botulinum toxin injection can be considered for children with a rectal evacuation disorder. Surgical management of constipation includes the use of antegrade continence enemas, sacral nerve stimulation, and colonic resection.

Idiopathic constipation: A challenging but manageable problem.

PURPOSE: A protocol to treat idiopathic constipation is presented. METHODS: A contrast enema is performed in every patient and, when indicated, patients are initially submitted to a "clean out" protocol. All patients are started on a Senna-based laxative. The initial dosage is empirically determined and adjusted daily, during a one week period, based on history and abdominal radiographs, until the amount of Senna that empties the colon is reached. The management is considered successful when patients empty their colon daily and stop soiling. If the laxatives dose provokes abdominal cramping, distension, and vomiting, without producing bowel movements, patients are considered nonmanageable. RESULTS: From 2005 to 2012, 215 patients were treated. 121 (56%) were males. The average age was 8.2years (range: 1-20). 160 patients (74%) presented encopresis. 67 patients (32%) needed a clean out. After one week, 181 patients (84%) achieved successful management, with an average Senna dose of 67mg (range: 5-175mg). In 34 patients (16%) the treatment was unsuccessful: 19 were nonmanageable, 3 noncompliant, and 12 continued soiling. At a later follow-up (median: 329days) the success rate for 174 patients was 81%. CONCLUSION: We designed a successful protocol to manage idiopathic constipation. The key points are clean out before starting laxatives, individual adjustments of laxative, and radiological monitoring of colonic emptying. TREATMENT STUDY: Level IV.

[Home training as a treatment of faecal incontinence and sphincter dyssynergia]. / Entrenamiento anorrectal domiciliario como tratamiento de la encopresis y disinergia esfinteriana.

OBJECTIVE: The defecation disorders represents the 3% of consultations in pediatrics patients. Our goal was to demonstrate the effectiveness and efficiency of the reeducation of the defecation maneuver through home training in patients with encopresis and sphincter dyssynergia. MATERIAL AND METHODS: Study of patients with fecal incontinence treated with home training at our center between 2014-2015. Anorectal manometry was performed and was valued defecation maneuver by expulsion of rectal probe with or without the ball. Daily sessions were performed using a Foley catheter (18-20Fr.) with progressive filling of the balloon, maximum 20cc. The response to the treatment was assessed in terms of episodes of soiling. RESULTS: Seven patients (6 males and 1 female) with a mean age of 9.7 years (range, 5-15) were included; two patients with anorectal malformation history, 1 Hirschsprung disease, 1 sacrococcygeal teratoma and 3 functional encopresis. Three patients had soiling episodes daily and 4 patients frequently. The mean basal pressure of anal channel was 32.34mmHg (range, 11.74-50.75) with negative defecation maneuver in 2 cases, deficient in 3 and dyssynergic in 2 patients. The mean time of biofeedback therapy to be asymptomatic was 5.14 months (range, 2-11), with a mean of 16.14 months (range, 3-24), with the 7 patients currently maintained clean. CONCLUSIONS: The present study suggests that re-education of defecation maneuver through home training, seems to be an effective and efficient therapy, achieving excellent results in medium term.

Antegrade continence enemas improve quality of life in patients with medically-refractory encopresis.

PURPOSE: Fecal incontinence is a socially debilitating problem for many children. We hypothesized that in selected patients with medically-refractory encopresis, placement of an appendicostomy or cecostomy tube for administration of antegrade continence enemas (ACE) would improve quality of life (QOL). METHODS: We reviewed all patients with encopresis who underwent appendicostomy or cecostomy placement from 2003 to 2014 at our institution. We contacted subjects' parents by phone and administered 3 surveys: a survey reflecting current stooling habits, a disease-specific QOL survey, and the PedsQL™ QOL survey. QOL surveys were completed twice by parents, once reflecting pre-operative QOL, then again reflecting current QOL. Pre-procedure and post-procedure scores were compared by paired t-test. RESULTS: Ten patients underwent appendicostomy/cecostomy for encopresis. Eight completed phone surveys. All procedures were performed laparoscopically. All patients experienced fecal soiling pre-operatively, whereas 5/8 surveyed patients (63%) noted complete resolution of soiling post-procedure (p<0.01). General and disease-specific QOL improved from pre-procedure to post-procedure in the following domains: social habits, physical activity, ability to spend the night elsewhere, feeling, and overall QOL (p<0.05). PedsQL™ scores improved significantly in physical functioning, social functioning, and overall functioning (p<0.05). CONCLUSIONS: Antegrade continence enemas significantly improve quality of life in patients with medically-refractory encopresis, likely related to resolution of soiling. LEVEL OF EVIDENCE: 4.

Milk and molasses enemas: clearing things up.

INTRODUCTION: We aimed to describe current nursing practice and clarify the safest and most effective dose of milk and molasses enemas used to relieve constipation in pediatric patients presenting to a suburban pediatric emergency department. METHODS: We surveyed emergency nurses about current practice in administration of milk and molasses enemas. In addition, we identified consecutive patients aged 2 to 17 years with a discharge diagnosis of constipation or abdominal pain between 2009 and 2012. Stable patients were included from the emergency department, in the absence of chronic medical conditions. For each patient, we recorded demographic characteristics, chief complaint, nursing administration technique, stool output, patient tolerance, side effects, amount of enema given, and patient disposition. RESULTS: We identified 500 patients with abdominal pain or constipation, 87 of whom were later excluded. Milk and molasses enemas were found to be effective at relieving constipation in our population, with a success rate averaging 88% in patients given 5 to 6 mL/kg with an institutional guideline maximum of 135 mL. The success rate was found to vary with age, along with the amount of enema given. DISCUSSION: Our nursing survey showed that varying practice exists regarding technique and dosing of milk and molasses enemas. Historical chart review showed that milk and molasses enemas in our emergency department were safe and effective with minimal side effects.

Psychomotor approach in children affected by nonretentive fecal soiling (FNRFS): a new rehabilitative purpose.

BACKGROUND: According to the Rome III criteria, encopresis without constipation was defined as nonretentive fecal soiling (FNRFS) with not yet well understood etiology. Treatment approaches reported in the literature with varying results include biofeedback, hypnosis, reflexology, and Internet-based educational programs. In developmental age, another behavioral treatment could be identified in the psychomotor approach, which is called psychomotricity in the European countries, or is also known as play therapy. The aim of the present study was to verify the safety and efficacy of play therapy plus toilet training in a small sample of prepubertal children affected by FNRFS. MATERIALS AND METHODS: Twenty-six patients (group 1; 16 males, mean age of 5.92 ± 0.84 years) underwent a psychomotor approach therapy program in association with toilet training for 6 months, and the other 26 subjects (group 2; 17 males, mean age of 5.76 ± 0.69) underwent the sole toilet training program for 6 months. During the observational time period (T0) and after 6 months (T1) of both treatments, the patients were evaluated for FNRFS frequency and for the behavioral assessment. RESULTS: At T0, the FNRFS mean frequency per month for group 1 was 20.115 episodes/month (standard deviation [SD] ± 3.024) and for group 2 was 20.423 (SD ± 1.879) (P = 0.661). At T1 the mean frequency per month was 6.461 (SD ± 1.333) episodes/month and 12.038 (SD ± 1.341), respectively (P < 0.001). Moreover, the delta percent average of the frequency between T0 and T1 was 67.121 ± 8.527 for group 1 and 40.518 ± 9.259 for group 2 (P < 0.001). At T1, a significant improvement in scores on the behavioral scale was identified. CONCLUSION: Our preliminary results show the importance of a multidisciplinary approach, and suggest the positive effect of an additional psychomotor approach, as this holds a new and interesting rehabilitative purpose for children in a toilet training program, even if further research is necessary.

Treatment Outcome in Patients with Pediatric Encopresis

PURPOSE: The causes of encopresis are complex and multifactorial. Through application of new sophisticated techniques and armamentarium, it has been possible to find more specific aspects of the anorectal function in pediatric patients with refractory defecation disorders. However, quality research of which therapeutic option could be suitable, is still lacking. The current study was designed to assess outcome of treatment according to the treatment algorithm based on the clinical and physiologic findings. METHODS: 22 patients (15 boys, 7 girls) with encopresis were analyzed, retrospectively. For exclusion of the organic cause, barium contrast study and anoscopy were carried out in all cases. Patients were categorized and made treatment algorithm by using leading symptoms and findings of anorectal physiologic tests. Treatment outcomes were analysed in the basis of respective therapeutic options. RESULTS: Patients were categorized as constipation dominant group (n=15) and incontinence dominant group (n=7). Suggested etipathogeneses were as follows; fecal impaction and/or motility disorder (n=7), overflow incontinence (n=6), sensory defect of the rectum (n=4), puborectalis incoordination (n=3), anal hypertonia (n=2). Treatment options were as follows; conventional therapy (CT) only (n=7), CT plus biofeedback (n=9), CT plus balloon sensory retraining (n=4), and CT plus internal sphincterotomy or Nitroglycerine application (n=2). All patients were undertaken a toilet training and psychologic consultation. Regarding to the therapeutic outcome, 19 (86 percent) of overall 22 patients were improved in the mean period of 2.5 (range, 0.1-7) years follow-up. CONCLUSIONS: If therapy could be undertaken according to the optional algorithm based on the clinical and physiologic findings, it could be useful guide for clinical decision making to help the therapy. Moreover, through the combination therapy including medication, psychological consultation, and biofeedback treatment, encopretic children achieve acceptable outcome with a long-term compliance.

Clinical and Physiologic Study of Encopresis

The pathophysiology of pediatric encopresis has been incomprehensible. The current study was designed to assess its clinical and physiologic findings. Moreover, outcome of treatment was evaluated. METHODS: The clinical and functional findings of 18 patients (13 boys, 5 girls) were analyzed, retrospectively. Physiologic studies for cooperative child included anal manometry (n=12), cinedefecography (n=3), and PNTML (pudendal nerve terminal motor latency, n=1). For exclusion of the organic cause, barium contrast study was carried out in all case. Patients were categorized by leading symptom as constipation or incontinence. Physiologic findings and outcome of treatment were analyzed based on the categorized groups. Biofeedback therapy by using newly-developed anal sphincter control system (KONTINENCE CLINICAL(TM)) in my institute, was underwent a mean 4.1 (range, 2~12) sessions. The outcome was analyzed in the period of 5.4 (range, 1~33) months follow-up. RESULTS: Patients were categorized as having constipation (group I, n=12) or incontinence (group II, n=6) group. In the manometric parameters, there were no statistical differences between the values of the mean resting pressure (RP), the maximum RP, and the maximum voluntary contraction between group I and II. In the cinedefecography, 3 of group I patients revealed as having the pelvic floor dyssynergia. The findings of PNTML were not specific in group II (n=1). Regarding to the therapeutic outcome, 8 of 10 patients were cured or improved. CONCLUSIONS: There were no differences in the resting and squeeze profiles of manometric parameters between two groups. However, pelvic floor dyssynergia was identified in the cinedefecography of constipated group. Conventional and biofeedback treatment for encopretic children provides acceptable outcome.

Anorectal Manometry in Idiopathic Constipation in Children / 대한소아소화기영양학회지

PURPOSE: Anorectal manometry is a way of investigation for anti-rectal sphincters. In this paper we evaluated the usefulness of anorectal manometry in constipation patients and compared the anal spnincter function in control, constipation and encopresis patients. METHOD: We analysed the data of anorectal function studies in normal children (control, n=11), children with constipation (constipation group, n=20) and children with encopresis (encopresis group, n=16). RESULTS: The specific manometric parameters in normal children were like as follows; external anal sphinter pressure 21.0+/-8.00 mmHg, internal anal sphicter pressure 30.0+/- 14.57 mmHg, conscious rectal sensitivity threshold 11.4+/-4.52 mmHg. The above results were not different from that of previous studies except conscious rectal sensitivity threshold, which was slightly lower than that of others. Internal and external anal sphincter pressure were elevated significantly in constipation and encopresis groups than in control, which results was the same in conscious rectal sensitivity threshold. But the values of rectoanal inhibitory threshold and percent relaxation of rectoanal inhibitory reflex were not different among control group, constipation group and encopresis group. External sphincter activity was increased during the act of bearing down for defecation in none of the child in control group, in 6 of 17 children in constipation group and 5 of 12 children in encopresis group. CONCLUSION: With the results of above we could say that complete history taking and physical examination are important in diagnosis of constipation, and we could say also that the anorectal manometry was a valuable tool to understand the physiology of normal defecation and the pathophysiology of constipation and encopresis.
