    Summary

    A man experienced retroperitoneal emphysema after a self-administered enema. This unusual case highlights the risks of intrarectal instrumentation, even without symptoms.

    Area of Science:

    • Gastroenterology
    • Radiology

    Background:

    • Enemas are commonly used for bowel preparation before medical procedures like intravenous pyelography.
    • Self-administration of enemas, particularly in older individuals, carries potential risks.

    Observation:

    • A 57-year-old man developed retroperitoneal emphysema following a self-administered enema.
    • The patient was asymptomatic and refused further investigation after initial diagnosis.
    • Abdominal X-rays and rectosigmoidoscopy were unremarkable.

    Findings:

    • The air distribution pattern suggested a small perforation at the rectosigmoid junction.
    • The absence of symptoms and physical signs in the presence of emphysema is highly unusual.
    • Mechanical factors, not typical enema pressures, are implicated in such rectal injuries.

    Implications:

    • This case underscores the need for caution during intrarectal instrumentation.
    • Healthcare providers should counsel patients on the risks associated with self-administered enemas.
    • Further investigation into managing asymptomatic rectal perforations may be warranted.
