Fecobionics, a simulated stool, safely and effectively assesses defecatory physiology by measuring pressures and movement during evacuation. This new method shows promise for diagnosing defecatory disorders.

Area of Science:

  • Gastroenterology
  • Physiology
  • Medical Device Development

Background:

  • Defecation is a complex physiological process.
  • Defecatory disorders require specialized diagnostic tools like anorectal manometry (ARM) and the balloon expulsion test (BET).
  • Existing methods have limitations in fully assessing defecatory function.

Purpose of the Study:

  • To evaluate the feasibility and performance of Fecobionics, a novel simulated stool, for assessing defecatory physiology in healthy individuals.
  • To compare Fecobionics' data with established methods like ARM-BET.

Main Methods:

  • An interventional study involving 16 healthy subjects (13 female/3 male, aged 25-78).
  • Fecobionics probe with pressure sensors and motion processors was used during simulated defecation.

Related Experiment Videos

  • Anorectal manometry-balloon expulsion test (ARM-BET) was also performed for comparison.

    • Main Results:

    • Fecobionics evacuation was perceived as similar to normal defecation by subjects.
    • Fecobionics demonstrated 5 distinct phases of expulsion, reflecting rectal and anal pressures.
    • Comparable variables showed agreement between Fecobionics and ARM-BET, indicating reliability.

    Conclusions:

    • Fecobionics is a safe and effective tool for evaluating key defecatory parameters under physiological conditions.
    • The device provides reliable data and shows potential for diagnosing defecatory disorders.
    • Fecobionics offers a promising advancement in the assessment of defecatory function.
