    Summary
    This summary is machine-generated.

    Defecography, a study of rectal and anal canal function, identified various dysfunctions in 83 patients. Findings included mucosal prolapse, internal procidentia, enterocele, and fecal retention, highlighting defecography

    Area of Science:

    • Gastroenterology
    • Colorectal Surgery
    • Diagnostic Imaging

    Background:

    • Defecation disorders, or dyschezia, affect rectal and anal canal function.
    • Conventional examination methods may not fully capture the dynamic nature of defecation.
    • Physiological assessment is crucial for understanding rectal dysfunction.

    Purpose of the Study:

    • To evaluate the utility of defecography in assessing patients with dyschezia.
    • To identify and quantify various anorectal abnormalities using defecography.
    • To determine the prevalence of specific defecation-related conditions in a patient cohort.

    Main Methods:

    • Defecography was performed on 83 patients presenting with dyschezia.
    • Patients were studied in a seated position, with recordings during rest and straining.

  • Analysis included assessment of rectal mucosal prolapse, internal procidentia, intussusception, enterocele, proctocele, fecal retention, pelvic floor descent, and rectoanal angle changes.

    • Main Results:

    • Defecation was normal in 28 patients.
    • Abnormal findings included anal mucosal prolapse (13 patients), internal procidentia (23 patients), intussusception (12 patients), deep rectogenital fossa with enterocele (16 patients), proctocele (13 patients), and fecal retention (5 patients).
    • Pelvic floor descent and changes in the rectoanal angle were also assessed.

    Conclusions:

    • Defecography provides a physiological assessment of rectal and anal canal function.
    • The technique is effective in identifying a range of anorectal abnormalities associated with dyschezia.
    • Defecography is recommended for evaluating patients with suspected rectal dysfunction.
