小儿蛲虫性阑尾炎(附124例报告)

Enterobiasis Appendicitis in Infancy——A Report of 124 Cases

蛲虫又名蠕形住肠线虫(1),人类是蛲虫的唯一宿主,也是儿童肠道常见的寄生虫.1982～1985年我院急性阑尾炎行手术治疗共1,343例,其中蛲虫性阑尾炎124例,占9.2%.

Among the 1,345 patients of acute appen-dicitis we treated from 1982 to 1985, 124 had eaterobiasis appendicits. The youngest was 1 yr. and 3 mths. and the oldest 14 yrs., and the ratio of male to female was 1.21:1. Most of them came from urban areas. Their major complaints were paroxymal abdomenal pain and tenderness in the right hypogastrium, and fever in 70% of the cases. No remarkable local myotonia was noticed and 56.5% of the cases also had upper respiratory tract infection. Swollen lymph nodes of the mesentary were detected on operation in nearly half of the cases.According to the pathological findings, these can be 'divided into three groups: simple enterobiasis appendicitis (63 cases), appendic-itis superficialis(51) and appendicitis phlegmo-nosa(10).Microscopically pinworms were found hav-ing invaded the submucosa and the muscular layers of the appendix. The crests on both sides of the head of a pinworm, seen in the sections, seem to be responsible for the mechanical damage to the mucosa of the appendix.
