In a prospective study of 518 consecutive appendices removed at surgery for symptomatic appendicitis, 32 appendices showed evidence of chronic Schistosoma haematobium appendicitis (a frequency of 6.2%). As the diagnosis can only be confirmed by histology of the removed appendix, the authors believe that in endemic areas chronic S. haematobium appendicitis may not be as rare as the few recorded cases would seem to suggest. Appendiceal mucosal ulceration with chronic inflammatory infiltration and fibrosis of the appendiceal wall leading to chronic appendicitis may be due to intense deposition of ova in the appendix wall, particularly the submucosa, by the adult worm.
在一项对因有症状性阑尾炎而接受手术切除的518例连续阑尾进行的前瞻性研究中，32例阑尾显示有慢性埃及血吸虫性阑尾炎的证据（发生率为6.2%）。由于该诊断只能通过切除阑尾的组织学检查来证实，作者认为在流行地区，慢性埃及血吸虫性阑尾炎可能并不像少数已记录病例所显示的那样罕见。阑尾黏膜溃疡伴慢性炎症浸润以及阑尾壁纤维化导致慢性阑尾炎，可能是由于成虫在阑尾壁尤其是黏膜下层大量产卵所致。
