A total of 110 consecutive patients presenting to one surgical firm with suspected acute appendicitis underwent peritoneal aspiration cytology. Aspiration was successful in 108 patients and 44 were positive. Patients with a positive result underwent emergency surgery; 42 had histologically proven acute appendicitis and two peritonitis of other causes. Seven patients with a negative result underwent appendicectomy; four had acute appendicitis and three a normal appendix. Peritoneal aspiration cytology had a sensitivity for acute appendicitis of 91 per cent and a specificity of 94 per cent. The positive predictive value of the test was 95 per cent and the negative predictive value 94 per cent. The negative appendicectomy rate was 10 per cent overall and 11 per cent in women of reproductive age. Peritoneal aspiration cytology is a useful diagnostic test in the management of patients with suspected acute appendicitis.
共有110例连续就诊于某外科科室、疑似急性阑尾炎的患者接受了腹腔穿刺细胞学检查。108例患者穿刺成功，其中44例结果为阳性。结果阳性的患者接受了急诊手术；42例经组织学证实为急性阑尾炎，2例为其他原因引起的腹膜炎。7例结果为阴性的患者接受了阑尾切除术；4例患有急性阑尾炎，3例阑尾正常。腹腔穿刺细胞学检查对急性阑尾炎的敏感性为91%，特异性为94%。该检查的阳性预测值为95%，阴性预测值为94%。总体阴性阑尾切除率为10%，育龄女性为11%。腹腔穿刺细胞学检查在疑似急性阑尾炎患者的管理中是一项有用的诊断检查。
