Faecal incontinence after anal dilatation.

S Snooks, M M Henry, M Swash

    The British Journal of Surgery
    |August 1, 1984
    PubMed
    Summary

    Faecal incontinence after anal dilatation may stem from external and internal anal sphincter dysfunction. Eight patients showed impaired internal sphincter function, impacting prevention strategies.

    Area of Science:

    • Gastroenterology
    • Colorectal Surgery
    • Physiology

    Background:

    • Faecal incontinence is a debilitating condition.
    • Anal dilatation is a medical procedure that can sometimes lead to complications.
    • Understanding the mechanisms of post-procedural incontinence is crucial.

    Purpose of the Study:

    • To investigate the causes of faecal incontinence following anal dilatation.
    • To identify specific sphincter abnormalities contributing to incontinence.
    • To inform preventative measures for this complication.

    Main Methods:

    • Clinical examination of 10 patients with post-dilatation faecal incontinence.
    • Manometric testing to assess anal sphincter pressures.
    • Single-fibre electromyography (EMG) to evaluate nerve function.

    Main Results:

    • Abnormalities in the external anal sphincter were detected in 5 patients via clinical and manometric tests.
    • Single-fibre EMG revealed abnormalities in 4 patients.
    • Internal anal sphincter dysfunction was a significant finding, present in 8 out of 10 patients.

    Conclusions:

    • Dysfunction of both external and internal anal sphincters can occur after anal dilatation.
    • Impaired internal anal sphincter function is a common finding in this patient group.
    • These results highlight the need for strategies to prevent faecal incontinence after anal dilatation.
