Appendices removed at cesarean section: histopathology

W I Onuigbo, W O Chukudebelu

    Diseases of the Colon and Rectum
    |October 1, 1981

    Summary

    Microscopic examination of appendices from healthy Nigerian women revealed lesions indicative of appendicitis, even in asymptomatic cases. Further research into crypt abscess and necrosis may unlock appendicitis pathogenesis secrets.

    Area of Science:

    • Pathology
    • Gastroenterology
    • Histopathology

    Background:

    • Appendicitis is a common surgical emergency.
    • The pathogenesis of appendicitis remains incompletely understood.
    • Subclinical appendiceal lesions may occur in asymptomatic individuals.

    Purpose of the Study:

    • To investigate the histopathological findings in the appendix of healthy Nigerian women undergoing cesarean section.
    • To explore the potential role of crypt abscess and crypt necrosis in appendicitis pathogenesis.

    Main Methods:

    • Microscopic examination of 100 appendix samples.
    • Analysis of three random cross-sections per appendix.
    • Categorization of observed lesions including luminal pus, fibrosis, ulceration, inflammation, crypt abscess, and crypt necrosis.

    Main Results:

    • Numerous appendiceal lesions were identified in asymptomatic women.
    • Lesions observed included luminal pus, fibrosis, mucosal ulceration, muscular inflammation, crypt abscess, and crypt necrosis.
    • Crypt abscess and crypt necrosis were identified as contrastable bipolar lesions.

    Conclusions:

    • The presence of appendiceal lesions in asymptomatic individuals suggests a potential for developing clinical appendicitis.
    • The crypt of Lieberkühn and its associated lesions (crypt abscess, crypt necrosis) are significant areas for future research into appendicitis pathogenesis.
    • Further global research on these histopathological findings could provide crucial insights into the multifaceted pathogenesis of appendicitis.
