TAPIA E, Óscar y MUNOZ C, César. Presence of Enterobius vermicularis in surgical pieces of appendectomies. Rev Chil Cir [online]. 2011, vol.63, n.6, pp.599-603. ISSN 0718-4026. http://dx.doi.org/10.4067/S0718-40262011000600009.
Background: The frequency of appendicular presence of Enterobius vermicularis varies from 0.2 to 41.8%. It is generally a pathological finding. The luminal obstruction by the parasite may unveil an acute appendicitis. Aim: To study the frequency of Enterobius vermicularis presence in surgical pieces of appendectomies. Material and Methods: Analysis of surgical pieces of appendectomies processed at the pathology laboratory of a general hospital, between 1993 and 2010. Results: In 21.038 surgical pieces, the presence of Enterobius vermicularis was found in 322 (1.5%). Fifty nine percent were women and 71% were younger than 18 years. Acute inflammation was confirmed in 71%. A history of previous abdominal pain was present in 40 and 70% of patients with and without acute inflammation in the surgical piece. Conclusions: In this series, the frequency of Enterobius vermicularis presence in surgical pieces of appendectomy was 1.5%.
