The role of parasitic infestation in the cause of acute appendicitis has been long time discussed. The aim of this study is to evaluate the role of parasitic infestation in the etiology of acute appendicitis.
This retrospective study includes 5.100 patients undergoing surgical therapy for acute appendicitis between 1996 and 2005. Patients were divided into two groups according to the presence of the parasites in the appendix lumen: in Group 1 (n=24) we observed parasitic infestation, whereas in patients of the Group 2 (n=5.076) no parasitic infestation was present.
Parasitic infestation was detected in 24 (0.5%). Of 24 parasitic infestation, 12 (50%) were enterobiasis, 6 (25%) were schistosomiasis, 4 (17%) were Ascaris lumbricoides, and 2 (8%) were Taenia saginata. The ratios of the patients with suppurative, gangrenous or perforative appendicitis were similar in both groups. The ratio of the normal histological findings in the Group 1 patients (25%) was significantly higher than that in the Group 2 patients (4.8%, p=0.001).
Although parasitic infestation may result in symptoms resembling acute appendicitis, parasitic infestation can't be considered in the etiology of acute appendicitis.
寄生虫感染在急性阑尾炎病因中的作用长期以来一直存在争议。本研究旨在评估寄生虫感染在急性阑尾炎病因学中的作用。
这项回顾性研究纳入了1996年至2005年间接受急性阑尾炎手术治疗的5100例患者。根据阑尾腔内是否存在寄生虫将患者分为两组：在第1组（n = 24）中，我们观察到寄生虫感染，而在第2组（n = 5076）的患者中未发现寄生虫感染。
检测到24例（0.5%）寄生虫感染。在24例寄生虫感染中，12例（50%）为蛲虫病，6例（25%）为血吸虫病，4例（17%）为蛔虫病，2例（8%）为牛带绦虫病。两组中化脓性、坏疽性或穿孔性阑尾炎患者的比例相似。第1组患者组织学检查正常的比例（25%）显著高于第2组患者（4.8%，p = 0.001）。
虽然寄生虫感染可能导致类似急性阑尾炎的症状，但在急性阑尾炎的病因中不能考虑寄生虫感染。
