Frequency of Appendicitis with Enterobius ver-micularis in Pathology Samples from the Last Ten Years in Bushehr (2012-2022)

Abstract

Background: The ectopic presence of helminths and their eggs in the appendix tube can directly and indirectly lead to the hyperplasia of lymphatic follicles in the walls of the tube by antigenic stimulation and thereby cause obstruction and subsequently acute appendicitis. The present study was designed to determine the extent of this role as well as the frequency of appendectomy samples with E. vermicularis during the last ten years in Bushehr. Materials and Methods: A total of 3210 slides related to appendiceal samples of appendectomy patients were collected in Bushehr over ten years (2012-2022) and examined in terms of microanatomy. The microscopic evaluation of the samples as well as the information contained in the patient health records were summarized and the collected data were analyzed in SPSS-16 software using the Chi-square test. Results: The frequency of appendicitis caused by E. vermicularis in the studied samples was 0.8%, showing a decreasing trend over the last years. There was a significant relationship between appendicitis caused by E. vermicularis and the gender and age of the patients, but there was no significant relationship with their place of residence. Conclusion: Considering the decreasing trend of appendicitis caused by Enterobius over the last few years in Bushehr, a role can be attributed to the COVID pandemic in this outcome. It is suggested to carry out preliminary evaluations for the early diagnosis of this parasitic infection, especially in infected areas, in order to eliminate unnecessary surgical interventions.
