Brief Summary

Constipation affects 12-19% of Americans. Pelvic floor dyssynergia is considered to play an important role in constipation but the underlying mechanisms are not well understood in individual patients. The investigators have developed a novel device named Fecobionics that provide detailed mapping of physiological parameters during defecation. The aim of the study is to use Fecobionics to assess anorectal function in dyssynergia patients and monitor and predict the outcome of the biofeedback therapy.

Outcome Measures

Primary Outcomes (2)

  • Expulsion Duration

    The time it takes to defecate Fecobionics

    1.5 year

  • Pressure Difference between front and rear ends of Fecobionics

    A measure of anal sphincter pressure, the driving rectal pressure, and the difference between these two pressures. This is the key to the determination of defecation phases.

    1.5 year

Secondary Outcomes (4)

  • Anorectal angle

    1.5 year

  • Mechanical Tension of Fecobionics

    1.5 year

  • Expulsion Velocity

    1.5 year

  • Cross-sectional area

    1.5 year

Study Arms (1)

Fecobionics

EXPERIMENTAL
Device: Fecobionics

Interventions

Fecobionics is a novel device to be inserted through the anal canal into rectum for studying defecation. Anorectal manometry and balloon expulsion test may be used as reference. Anorectal manometry and balloon expulsive test are standard methods for anorectal functional measurement.

Also known as: Anorectal manometry, Balloon expulsive test
Fecobionics
