Appendectomy in Appendiceal Parasitosis: A Retrospective Analysis.
J Surg Pak Jan ;19(3):100-3.

Objective: To evaluate the role of parasitic infestation in the etiology of acute appendicitis. Study design: Descriptive case series. Place & Duration of study: Department of Surgery, Pakistan Institute of Medical Sciences Islamabad, Pakistan, from January 2012 to June 2014. Methodology: A retrospective analysis of histopathology reports of 1617 appendix specimens of patients of all ages and gender who underwent appendectomy for acute appendicitis was done. Detail histopathology reports of 65 cases with appendiceal parasitosis were examined. Data were analyzed through IBM SPSS version 20. Results: A total of 65 specimens of appendiceal parasitosis amongst 1617 appendectomy cases produced a frequency of 4.02%. Mean age group of patients with appendiceal infestation was 14.38 + 9.83 year with an overwhelming (50.76%) presenting in the second decade of life. Male to female ratio was 1.24:1. Normal histology (n=39, 60%) was most frequently reported followed by lymphoid hyperplasia (n=18, 27.6%) whereas only 07 (9.85%) cases of parasitic infestation had acute or acute suppurative appendicitis. Conclusions: Appendiceal parasitosis may result in symptoms mimicking acute appendicitis without causing acute inflammation of the appendix so it cannot be considered conclusively in the etiology of acute appendicitis. Medical therapy must be instituted for cases of parasitic infestations.
