Comparison of treatment methods in plastron appendicitis: a tertiary center experience.

Background: It is controversial which treatment method is superior in plastron appendicitis and the research is still going on. The aim of this study is to compare treatment methods for plastron appendicitis in the adult population with our experience. Materials and Methods: The data of 92 patients who were diagnosed with plastron appendicitis in university hospital between 2015 and 2021 were analyzed retrospectively. Data were taken from the hospital database. The patients were divided into three groups: those treated with primary surgery, with interval appendectomy and only with conservative method. Results: Interval appendectomy resulted in a lower rate of conversion to open surgery compared to primary surgery, shorter operative time, and lower complication rates. Surgical procedures were found to be superior in detecting neoplasms compared to conservative treatment. After conservative treatment, one of three patients was retreated with the diagnosis of acute appendicitis. Conclusion: In plastron appendicitis, routine interval appendectomy can be performed due to its advantages over other treatments such as the frequency of attacks after conservative treatment, the risk of the tumor being overlooked in conservative treatment, and the high rate of complications and conversion to open surgery in the primary surgery group.
