Repeated vaginal deliveries can negatively impact anorectal function in perimenopausal women. This study found long-term effects on perineal position, anal sensation, and nerve latency with increased parity.

Area of Science:

  • Obstetrics and Gynecology
  • Colorectal Surgery
  • Pelvic Floor Disorders

Context:

  • Perimenopausal women are susceptible to changes in pelvic floor function.
  • Vaginal delivery is a common obstetric procedure with potential long-term consequences.
  • Anorectal function is crucial for quality of life and is influenced by parity.

Purpose:

  • To investigate the long-term effects of vaginal deliveries on anorectal function in perimenopausal women.
  • To correlate the number of vaginal deliveries with specific measures of anorectal function.
  • To assess the impact of parity on perineal position, anal electrosensitivity, sphincter pressures, and pudendal nerve latency.

Summary:

  • An observational study of 144 perimenopausal women examined the relationship between parity and anorectal function.

  • Increasing parity correlated with lowered perineal position, increased anal sensory threshold, and prolonged pudendal nerve terminal motor latency.
  • No significant effect of parity was observed on maximum resting or squeeze pressures of the anal sphincters.

    • Impact:

    • Findings suggest that repeated vaginal deliveries have a long-term adverse effect on anorectal function in healthy perimenopausal women.
    • This research highlights the importance of considering obstetric history when evaluating anorectal dysfunction.
    • Understanding these long-term effects can inform patient counseling and management strategies for pelvic floor health.
