Comparison Between an Appendiceal Abscess and Uncomplicated Appendicitis with Conservative Treatment

Abstract

Objective: The aim of this study was to verify the validity of conservative treatment for appendiceal abscesses (AAs). Patients and Methods: Patients who underwent conservative treatment for acute appendicitis in our hospital were enrolled in this study. We divided them into two group: the AA group and the uncomplicated appendicitis (UA) group. Analysis 1: We compared the outcomes of conservative management between the two groups. Analysis 2: We also compared the outcomes of interval appendectomy after conservative treatment between the two groups. Results: There were 56 and 133 patients in the AA and US groups, respectively. C-reactive protein levels in the AA group was higher than in the UA group. In the AA group, the hospital stay was longer and the rate of intraabdominal drainage procedure in AA group was higher than in the UA group. On the other hand, there was no difference in the rate of failure of conservative treatment, the complication or recurrence rates. The outcome of interval appendectomy was also no different between the two groups. Conclusion: Based on our findings, conservative treatment for appendiceal abscesses might be valid.
