Pudendal nerve function is normal in children with encopresis (involuntary defecation). External anal sphincter non-relaxation is common in encopretic children, but pudendal neuropathy is not a significant cause.

Area of Science:

  • Pediatric Gastroenterology
  • Neuroscience
  • Urology

Background:

  • Abnormal pudendal nerve function is linked to fecal issues in adults.
  • The role of pudendal neuropathy in childhood encopresis requires investigation.

Purpose of the Study:

  • To evaluate pudendal nerve function in children with encopresis.
  • To compare pudendal nerve function between encopretic and healthy children.

Main Methods:

  • Pudendal nerve terminal motor latency was measured in 23 encopretic and 23 control children.
  • Anal manometry and electromyography were performed on all participants.

Main Results:

  • Pudendal nerve latency was similar in encopretic and control groups.

  • External anal sphincter non-relaxation occurred in 75% of encopretic children.
  • Anorectal manometry showed lower pressures in encopretic children, but few had significantly abnormal sphincter pressures.

    • Conclusions:

    • Pudendal nerve function is not significantly impaired in childhood encopresis.
    • External anal sphincter dysfunction is a key finding in encopretic children.
    • Pudendal neuropathy is unlikely to be a primary cause of encopresis in children.
