Enterobius vermicularis is one of the common parasites in the world. The infestation rate of Enterobius vermicularis is higher in children than in adults. Moreover, the egg-positive rate of Enterobius vermicularis is higher in the mentally retarded population. We report the case of a ten-year-old, mentally retarded boy, who was diagnosed as having acute appendicitis associated with Enterobius vermicularis.
Enterobius vermicularis (pinworm) infection occurs in 4~28% worldwide. Although the most common clinical manifestation is perianal pruritis, it may cause gastrointestinal manifestations, including acute appendicitis in about 0.2~41.8% of infections. Preoperative diagnosis of pinworms in patients with acute appendicitis is not routinely performed. We performed a laparoscopic appendectomy for an acute appendicitis caused by Enterobius vermicularis. To our knowledge, this is the first report of a laparoscopic appendectomy for acute appendicitis caused by Enterobius vermicularis in Korea.
