    Conservative treatment for appendix mass avoids surgery in 80% of patients. Recurrent appendicitis occurred in 20%, with most cases developing within two years, suggesting careful follow-up is key.

    Area of Science:

    • Gastroenterology
    • Surgical Outcomes

    Background:

    • Appendix mass management traditionally involves conservative treatment followed by interval appendectomy.
    • The necessity and cost-effectiveness of routine interval appendectomy after conservative treatment are debated.

    Purpose of the Study:

    • To evaluate the outcomes of conservative management for appendix mass without immediate interval appendectomy.
    • To determine the rate of recurrence and long-term complications.

    Main Methods:

    • Retrospective analysis of 49 patients treated conservatively for appendix mass.
    • Follow-up ranged from 6 months to 22 years.
    • Barium examination used for differential diagnosis of right iliac fossa masses.

    Main Results:

    Related Experiment Videos

    • 80% of patients avoided interval appendectomy.
    • Recurrent appendicitis developed in 9 patients (20%), with 66% occurring within 2 years.
    • Chronic pain, unrelated to appendicitis, affected 6 patients (14%).
    • Barium studies diagnosed non-appendiceal masses in 2 of 3 patients.

    Conclusions:

    • Conservative management of appendix mass is effective in a majority of patients, eliminating morbidity and expense associated with routine interval appendectomy.
    • Careful monitoring is necessary due to the risk of recurrent appendicitis within the first two years.
    • Non-appendiceal causes of right iliac fossa masses can be identified with barium examination.
