There is little evidence regarding the relationship between parasites and acute appendicitis. In order to determine such a relationship, if any, 830 appendectomy specimens were studied. Age, sex, pathological findings and the presence and type of parasites and the type of parasite were analyzed. Parasites were present in 62 cases (7.46%). Ascaris lumbricoides and Trichuris trichiura were the most frequently encountered parasites. These were observed, alone or in combination, in 45 cases (72.5%). Appendix perforation, peritonitis, necrosis and flegmonous appearance, were more frequent in the cases of acute appendicitis without parasitic infestation (p < 0.05). There were no differences between the cases with or without parasitic infestation (p > 0.05) In cases of peritonitis. The low incidence of parasites among the appendectomy specimens and the failure to demonstrate its relationship with all events derived of appendicitis, do not support the hypothesis that parasites are a major cause of appendicitis in pediatric patients.
关于寄生虫与急性阑尾炎之间的关系，几乎没有证据。为了确定是否存在这种关系，对830份阑尾切除标本进行了研究。分析了年龄、性别、病理结果以及寄生虫的存在情况、类型。62例（7.46%）存在寄生虫。蛔虫和鞭虫是最常遇到的寄生虫。单独或合并出现于45例（72.5%）。在无寄生虫感染的急性阑尾炎病例中，阑尾穿孔、腹膜炎、坏死和蜂窝织炎样表现更为常见（p<0.05）。在腹膜炎病例中，有无寄生虫感染的病例之间没有差异（p>0.05）。阑尾切除标本中寄生虫的低发生率以及未能证明其与阑尾炎所有相关事件的关系，不支持寄生虫是小儿阑尾炎主要病因这一假说。
