Progress of acute appendicitis: a study in children

N V Doraiswamy

    The British Journal of Surgery
    |December 1, 1978
    PubMed
    Summary

    Acute appendicitis progresses through inflamed, infected, and complicated stages within days. Bacterial invasion, not faeoliths, appears to drive disease progression in children.

    Area of Science:

    • Pediatric Surgery
    • Gastrointestinal Pathology
    • Infectious Diseases

    Background:

    • Acute appendicitis is a common surgical emergency in children.
    • Understanding the temporal progression of appendicitis is crucial for timely intervention.
    • The role of luminal bacteria and faeoliths in appendicitis pathogenesis requires clarification.

    Purpose of the Study:

    • To investigate the chronological development of acute appendicitis in pediatric patients.
    • To correlate disease duration with local defense mechanisms and bacterial invasion.
    • To elucidate the etiological contribution of bacteria and faeoliths.

    Main Methods:

    • Comparative analysis of six investigations against disease duration in 100 children with acute appendicitis.
    • Assessment of local defense mechanisms in the appendix.
    • Identification and analysis of bacterial organisms and faeoliths within the appendix lumen.

    Main Results:

    • Inflammation on day one impairs local defenses, allowing bacterial invasion from the lumen.
    • Appendicitis progresses through distinct stages: inflamed, infected, and complicated, each developing approximately one day apart.
    • Bacteria and faeoliths are consistently found in the appendix lumen, regardless of inflammation status.

    Conclusions:

    • Bacterial invasion is a key factor in the progression of acute appendicitis.
    • Faeoliths may complicate, rather than cause, appendicitis.
    • The staged development of appendicitis occurs rapidly, within a few days.
