Insights
Functional faecal incontinence (FI) in children is common, often linked to constipation. While retentive FI has advances, nonretentive FI options are limited, though most children improve over time.
Area of Science:
- Pediatric Gastroenterology
- Child Health
- Bowel Dysfunction
Background:
- Functional faecal incontinence (FI) significantly impacts children's lives, characterized by recurrent involuntary defecation.
- While both functional and organic causes exist, functional etiologies are more prevalent.
Purpose of the Study:
- To comprehensively review the epidemiology, pathophysiology, clinical evaluation, and management strategies for functional faecal incontinence in pediatric populations.
- To synthesize current knowledge on the diagnosis and treatment of childhood FI.
Main Methods:
- A systematic literature search was performed using PubMed with keywords 'faecal incontinence' and 'encopresis'.
- Relevant articles focusing on epidemiology, pathophysiology, clinical evaluation, investigation, and management of functional FI in children were retrieved and analyzed.
Main Results:
- Community prevalence of FI in children ranges from 0.8% to 7.8% globally, with a male predominance (3:1 to 6:1).
- Constipation is associated with the majority (82%) of functional FI cases; biopsychosocial factors are key to pathogenesis.
- Management requires a multidisciplinary approach, including pharmacotherapy and behavioral treatments, with limited physiological testing recommended for atypical cases.
Conclusions:
- Therapeutic advances are notable for retentive faecal incontinence, yet options for functional nonretentive faecal incontinence remain limited.
- Long-term data suggest most children eventually outgrow faecal incontinence, but a significant portion may experience persistent symptoms into adulthood.
Background:
Faecal incontinence (FI) in children is a significant gastrointestinal problem, with great personal and social impacts. It is characterised by recurrent loss of faecal matter into the underwear. Both functional and organic causes contribute to its aetiology with the former predominating.
Aim:
To review the epidemiology, pathophysiology, clinical evaluation and management of functional faecal incontinence in children.
Methods:
A PubMed search was conducted using search terms f(a)ecal incontinence, and encopresis. Articles on epidemiology, pathophysiology, clinical evaluation, investigation and management of functional FI in children were retrieved and assessed.
Results:
Community prevalence of this distressing problem ranges from 0.8% to 7.8% globally. Male: female ratio varies from 3:1 to 6:1. The diagnosis of FI is often based on established clinical criteria. The majority (82%) have constipation associated functional FI. Biopsychosocial factors play a crucial role in the pathogenesis. Limited physiological testing of anorectal function is recommended in the diagnostic procedures, particularly in children with atypical symptoms and possible organic disorders. Management of FI needs a multidisciplinary approach which includes establishment of an effective doctor-patient partnership, understanding the underlying mechanisms, pharmacotherapy and behavioural treatment. Approximately 15% of children with functional nonretentive faecal incontinence (FNRFI) had the same symptoms at the age of 18 years.
Conclusion:
Significant therapeutic advances have been made for retentive faecal incontinence, but treatment options for functional nonretentive faecal incontinence are limited. Limited long-term outcome data show that the majority outgrow faecal incontinence. A substantial proportion of children progress to adulthood with faecal incontinence.
