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.

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:
Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Urinary Tract Infection II: Pathophysiology

The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...

Renal calculi, commonly termed kidney stones, are crystalline solid masses that form in the kidneys but can occur at any point within the urinary system, encompassing the kidneys, ureters, bladder, and urethra.The pathophysiology of renal stones involves several key factors: supersaturation of the urine with stone-forming constituents, changes in urine pH, a decrease in urine volume, and the presence of substances that promote or inhibit stone formation.Supersaturation of Urine: This is the...
