Defecating proctography revealed significant defecating mechanism abnormalities in 88.8% of patients with constipation. This study highlights the diagnostic value of defecating proctography for these conditions.

Area of Science:

  • Colorectal surgery
  • Gastroenterology
  • Diagnostic imaging

Background:

  • Persistent constipation and incomplete evacuation are common patient complaints.
  • Understanding the anatomical and functional causes is crucial for effective treatment.
  • Defecating proctography is an underutilized diagnostic tool in some regions.

Purpose of the Study:

  • To evaluate the utility of defecating proctography in patients with defecation disorders.
  • To identify common anatomical and functional abnormalities.
  • To report on the methodology and findings of this investigation.

Main Methods:

  • Defecating proctography was performed on 27 patients between October 1990 and November 1991.
  • Patients presented with symptoms of chronic constipation or sensation of incomplete evacuation.

  • The procedure visualizes the anorectal function during defecation.

    • Main Results:

    • A high prevalence of abnormalities (88.8%) was observed in the defecating mechanism.
    • Identified abnormalities included rectocele formation, intrarectal mucosal prolapse, intussusception, and pubo-rectalis paradox.
    • These findings suggest underlying structural or functional issues impacting defecation.

    Conclusions:

    • Defecating proctography is effective in diagnosing defecation abnormalities.
    • A significant proportion of patients with constipation exhibit treatable defecating mechanism issues.
    • Surgical correction may be a viable option for some identified abnormalities.
