Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Diagnostic Medicine

Background:

  • Diagnostic tests are crucial for understanding pathophysiology, confirming clinical suspicions, and guiding patient management.
  • Anorectal disorders often present complex diagnostic challenges.

Purpose of the Study:

  • To evaluate the diagnostic utility and impact of anorectal manometry in patients with defecation disorders.
  • To assess the role of colorectal physiologic tests in diagnosing constipation, incontinence, and anorectal pain.

Main Methods:

  • Prospective study evaluating anorectal manometry.
  • Review of studies on colorectal physiologic tests for constipation, incontinence, and anorectal pain.

Main Results:

Related Experiment Videos

  • Anorectal manometry confirmed clinical impressions and provided novel information, influencing patient management and outcomes.
  • Colorectal physiologic tests yielded definitive diagnoses in 75% of constipation, 66% of incontinence, and 42% of intractable anorectal pain cases.

    • Conclusions:

    • Systematic anorectal function assessment provides invaluable information for guiding treatment of anorectal disorders.
    • Standardized methods for performing and interpreting anorectal manometry are needed to increase its clinical utility.
