Evacuation proctography in obstructed defaecation and rectal intussusception.

D C Bartolo, A M Roe, J Virjee

    The British Journal of Surgery
    |September 1, 1985
    PubMed
    Summary

    Obstructed defecation involves several syndromes. This study found neuropathic changes and abnormal anorectal dynamics during straining, aiding surgical treatment planning.

    Area of Science:

    • Gastroenterology
    • Colorectal Surgery
    • Physiology

    Background:

    • Obstructed defecation (OD) presents with diverse syndromes like rectal prolapse and solitary rectal ulcer.
    • Pathophysiology of OD requires detailed investigation to guide effective treatment.

    Purpose of the Study:

    • To elucidate the pathophysiology of severe, intractable obstructed defecation.
    • To identify radiological, manometric, and electrophysiological differences between OD patients and controls.

    Main Methods:

    • Dynamic and static radiological investigations (including evacuation proctography).
    • Manometric and electrophysiological measurements (sphincter pressures, recto-anal inhibitory reflex, motor unit potential duration).
    • Comparison of 10 OD patients with 35 healthy controls.

    Main Results:

    • No significant differences in resting sphincter pressures or recto-anal inhibitory reflex.
    • Prolonged motor unit potential duration in puborectalis and external sphincter, suggesting neuropathic changes.
    • Increased anorectal angle and perineal descent during straining in OD patients.
    • Evacuation proctography revealed anterior rectal wall occlusion and recto-rectal intussusception in some patients.

    Conclusions:

    • Obstructed defecation is associated with neuropathic changes and abnormal anorectal dynamics during defecation.
    • Radiological findings like rectal intussusception explain obstructive symptoms.
    • Understanding these abnormalities enables rational, anatomy-based surgical treatment planning.
