Colorectal dysfunction and faecal incontinence in children with spina bifida

Pediatric Neurogenic Bladder and Bowel Dysfunction: Will My Child Ever Be out of Diapers?

CONTEXT

Managing patient and parent expectations regarding urinary and fecal continence is important with congenital conditions that produce neurogenic bladder and bowel dysfunction. Physicians need to be aware of common treatment algorithms and expected outcomes to best counsel these families.

OBJECTIVE

To systematically evaluate evidence regarding the utilization and success of various modalities in achieving continence, as well as related outcomes, in children with neurogenic bladder and bowel dysfunction.

EVIDENCE ACQUISITION

We performed a systematic review of the literature in PubMed/Medline in August 2019. A total of 114 publications were included in the analysis, including 49 for bladder management and 65 for bowel management.

EVIDENCE SYNTHESIS

Children with neurogenic bladder conditions achieved urinary continence 50% of the time, including 44% of children treated with nonsurgical methods and 64% with surgical interventions. Patients with neurogenic bowel problems achieved fecal continence 75% of the time, including 78% of patients treated with nonsurgical methods and 73% with surgical treatment. Surgical complications and need for revisions were high in both categories.

CONCLUSIONS

Approximately half of children with neurogenic bladder dysfunction will achieve urinary continence and about three-quarters of children with neurogenic bowel dysfunction will become fecally continent. Surgical intervention can be successful in patients refractory to nonsurgical management, but the high complication and revision rates support their use as second-line therapy. This is consistent with guidelines issued by the International Children's Continence Society.

PATIENT SUMMARY

Approximately half of children with neurogenic bladder dysfunction will achieve urinary continence, and about three-quarters of children with neurogenic bowel dysfunction will become fecally continent. Most children can be managed without surgery. Patients who do not achieve continence with nonsurgical methods frequently have success with operative procedures, but complications and requirements for additional procedures must be expected.

Improved Bowel Function in Patients with Spina Bifida After Bone Marrow-Derived Mononuclear Cell Transplantation: A Report of 2 Cases

BACKGROUND Bowel dysfunction is observed in 42.2-71.2% of patients with spina bifida. Traditional treatments yield limited results. The objective of this paper is to report on improvement in bowel function in 2 children with spina bifida following bone marrow-derived mononuclear cells transplantation. CASE REPORT Two patients - 14 years old and 11 years old - with bowel dysfunction after myelomeningocele repair underwent 2 BMMNC transplantations without complications. Those patients had normal defecation, assessed through follow-ups of 21 months and 16 months, respectively. CONCLUSIONS BMMNC transplantation can improve bowel function, as demonstrated in 2 patients with spina bifida.

Review of organic causes of fecal incontinence in children: evaluation and treatment

Even though fecal incontinence (FI) in children is most commonly the result of functional constipation, there are organic conditions that can be associated with incontinence. FI has a major impact on the quality of life of those children who experience it. The general objectives of any bowel program are to achieve predictability and independence. This is achieved by manipulating colonic transit and stool consistency and by producing more controlled evacuations, usually with the use of rectal interventions. Dietary interventions and medications can be used to change stool consistency or to manipulate transit by accelerating or slowing it down. Biofeedback or other interventions that increase sphincter pressure can also be used to improve anorectal function. Enemas or suppositories can be used to empty the sigmoid colon in a more controlled manner. With the recent advent of the antegrade colonic enemas, the patient can have predictable bowel movements and become independent.

Descriptive analysis of 258 emergency department visits by spina bifida patients

To provide a descriptive analysis of emergency department (ED) patients with spina bifida, a retrospective chart review was conducted of ED patients with spina bifida. Data describing demographics, chief complaints, diagnostics, diagnoses, and disposition were collected. There were 125 patients with 258 ED visits. The most common presenting complaints included fever (n = 55), vomiting (36), headache (32), abdominal pain (23), and genitourinary symptoms (20). The most common diagnoses included urinary tract infection (n = 55), cellulitis (26), seizure (21), headache (17), dehydration (12), and shunt failure (11). Atypical presentations of conditions commonly associated with spina bifida occurred frequently. Forty-three percent of patients were admitted. In conclusion, spina bifida patients often present with serious illness requiring admission and with complications of their underlying condition. Therefore, atypical presentations of commonly associated conditions must be considered.

High prevalence of incontinence among young adults with spina bifida: description, prediction and problem perception

STUDY DESIGN

Cross-sectional study.

OBJECTIVES

To study the prevalence of incontinence, problem perception and determinants of urinary and faecal incontinence in young adults with spina bifida.

SETTING

Nation-wide study in the Netherlands.

PARTICIPANTS

A total of 179 of 350 invited patients participated, including 37 patients with spina bifida occulta and 142 with spina bifida aperta, of whom 119 had hydrocephalus; 41% were male and mean age was 20.4 (range 16-25 years).

METHODS

Data were collected from interviews, physical examination, neuropsychological tests and medical records.

RESULTS

Urinary and faecal incontinence was common in young adults with spina bifida (60.9 and 34.1%, respectively), regardless of the bladder and bowel management they used. The majority of urinary and faecal incontinent patients perceived this as a problem (69.7 and 77.0%, respectively). Spina bifida aperta, hydrocephalus and a level of lesion of L5 or above were associated with patients suffering from urinary and/or faecal incontinence. Predictors of perceiving urinary incontinence as a problem were, in addition to being incontinent, not having hydrocephalus and having a level of lesion of L5 or above. The only predictor of perceiving faecal incontinence as a problem was the frequency of incontinence.

CONCLUSION

A majority of young adults with spina bifida suffer from urinary and faecal incontinence and most of them perceive their incontinence as a problem. Therefore, further efforts are important to improve urinary and faecal continence.

Intravesical electrical stimulation improves neurogenic bowel dysfunction in children with spina bifida

PURPOSE

We observed concomitant improvement in fecal incontinence in children with myelomeningocele undergoing intravesical electrical stimulation (IVES) to decrease uninhibited bladder contractions and increase bladder capacity and/or bladder sensation. We retrospectively reviewed the effect of intravesical electrical stimulation on neurogenic bowel dysfunction in these children.

MATERIALS AND METHODS

A total of 9 boys and 15 girls 3.9 to 13.2 years old (mean age 8.1) completed a mean of 30.3 daily sessions (range 10 to 69) of IVES. Evaluation forms were used to record frequency of fecal incontinence, daily bowel movement and diaper use before and after IVES.

RESULTS

The mean number of overall fecal incontinence episodes decreased significantly from 7.36 to 4.8 a week after IVES (p <0.05). Greater than 50% decrease in the episodes of fecal incontinence was observed in 75% of the patients. However, there was no significant change in the number of daily bowel movements before (1.8 daily) and after (1.55 daily) IVES.

CONCLUSIONS

These results demonstrate the therapeutic effect of IVES in children with neurogenic bowel dysfunction and spina bifida. We believe that IVES is another viable option for controlling fecal incontinence in these children.

Pathophysiology of pediatric fecal incontinence

This article addresses the diagnosis and treatment of pediatric fecal incontinence in 4 main categories: (1) Functional fecal retention, the withholding of feces because of fear of painful defecation, results in constipation and overflow soiling. Treatment includes dietary changes, use of laxatives, and cognitive and behavioral interventions such as toilet training, which diminishes phobia and provides positive reinforcement through a rewards system. (2) For functional nonretentive fecal soiling (encopresis), antidiarrheal agents can increase the consistency of stools and facilitate continence. Anorectal biofeedback for children has been proposed, but its efficacy remains unproven. Parents should be educated to conduct nonaccusatory toilet training and help children alleviate guilt and enhance self-esteem. Appropriately constructed trials are necessary to gauge the effect of adding prolonged use of enemas to an intensive toilet training program. (3) Surgery can correct minor congenital anorectal anomalies by identifying the external sphincter, separating the rectum from the genitourinary tract, and reconstructing the anus. However, there is great variation in postsurgical functional outcomes for anorectal malformations. Double-blinded, randomized controlled trials could help define the role of appendicostomy, cecostomy, sphincter reconstruction, colostomy, and artificial sphincters. (4) Children with spina bifida and fecal incontinence may benefit from techniques that teach them how to defecate. A continent appendicostomy (Malone procedure) is a promising treatment that completely cleanses the colon, increases the child's autonomy, and decreases the chance of soiling. A cecostomy can be performed surgically, endoscopically, or radiologically to provide some of the same benefits.

Colorectal symptoms in patients with neurological diseases

Several neurological diseases cause constipation or faecal incontinence restricting social activities and influencing quality of life. As several new treatment modalities have become available within the last few years, doctors treating patients with neurological diseases should be aware of the symptoms and have a basic knowledge of relevant treatment options. Constipation and faecal incontinence are common symptoms in patients with traumatic spinal cord injuries, spina bifida, multiple sclerosis, diabetic polyneuropathy, Parkinson's disease, stroke, and cerebral palsy. New treatment modalities are: prokinetic agents, enemas administered through the enema continence catheter or through an appendicostomy, and biofeed-back. Sacral nerve stimulation is still mostly at an experimental level and colostomy should be restricted to the few patients with most severe problems resistant to other therapy.
