Defecography reveals common rectal static disorders in chronic constipation patients, including anterior rectocele and increased perineal descent. Some abnormalities may cause or result from constipation.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Diagnostic Imaging

Background:

  • Defecography is a key examination for evaluating defecation and continence issues.
  • Idiopathic chronic constipation affects a significant portion of the population, impacting quality of life.

Purpose of the Study:

  • To introduce a simplified defecography technique.
  • To evaluate the diagnostic validity of this technique in healthy individuals and constipated patients.

Main Methods:

  • A simplified defecography technique was applied to 10 healthy controls and 35 patients with idiopathic chronic constipation.
  • Measurements included anorectal angle (RAA) at rest and during straining, rectocele presence, puborectal muscle imprint, and perineal descent (PD).

Main Results:

Related Experiment Videos

  • Constipated patients showed significantly higher rates of anterior rectocele (50% vs 20%) and persistent puborectal muscle imprint (36% vs 10%) compared to controls.
  • A specific closure of the RAA during straining was observed only in constipated patients (35%), often associated with minimal perineal descent, suggesting pelvic floor hypertonia.
  • Perineal descent was significantly greater in constipated patients (mean 2.7 cm vs 2.0 cm).

Conclusions:

  • Simplified defecography effectively identifies rectal static abnormalities in chronic constipation.
  • Findings like anterior rectocele, puborectal muscle imprint, and increased perineal descent are more prevalent in constipated individuals.
  • These disorders can be either causative or consequential to chronic constipation, highlighting the complexity of pelvic floor dysfunction.
