    Pathologic abnormalities are common in incidentally removed appendices during jejunoileal bypass surgery. These findings suggest self-limiting inflammation and fibrosis are typical appendix sequelae, with incidental appendectomy posing no added surgical risk.

    Area of Science:

    • Gastroenterology
    • Surgical Pathology

    Background:

    • Jejunoileal bypass surgery is a bariatric procedure.
    • Incidental appendectomy is sometimes performed during this surgery.

    Purpose of the Study:

    • To report the incidence of pathologic abnormalities in incidentally removed appendices during jejunoileal bypass.
    • To evaluate the safety of incidental appendectomy in potentially contaminated procedures.

    Main Methods:

    • Histopathologic examination of appendices removed incidentally during jejunoileal bypass.
    • Analysis of operative morbidity and mortality data for procedures with and without incidental appendectomy.

    Main Results:

    • Thirty-one percent of incidentally removed appendices showed significant histopathologic changes.

  • Incidental appendectomy did not increase operative morbidity or mortality in potentially contaminated primary procedures.

    • Conclusions:

    • Findings support the theory of self-limited acute inflammation and subsequent fibrosis in the appendix.
    • Incidental appendectomy is a safe addition to jejunoileal bypass, even in contaminated cases.
