    Summary

    Fecal continence relies on both anal sphincters. The internal anal sphincter maintains resting pressure, while the external anal sphincter reacts to rectal distension to ensure continence.

    Area of Science:

    • Gastroenterology
    • Physiology

    Background:

    • Fecal continence is crucial for quality of life.
    • Understanding the rectoanal reflex is key to managing incontinence.

    Purpose of the Study:

    • To investigate the rectoanal reflex in healthy individuals.
    • To elucidate the roles of anal sphincters in maintaining fecal continence.

    Main Methods:

    • Rectoanal reflex examination in healthy subjects.
    • Analysis of anal sphincter activity during rectal distension.

    Main Results:

    • Fecal continence is supported by coordinated action of both anal sphincters.
    • Maximal anal pressure at rest is primarily regulated by the internal anal sphincter.
    • The external anal sphincter demonstrates rapid contraction in response to rectal distension.

    Conclusions:

    • Both internal and external anal sphincters are essential for fecal continence.
    • Differential roles of the anal sphincters in maintaining continence are confirmed.
