Fifty-one patients in whom a clinical diagnosis of acute appendicitis had been made underwent peritoneal aspiration cytology (PAC). Thirty-six had a positive result, 11 had a negative result and aspiration failed in four cases. All patients had an appendicectomy and the histological findings were correlated with the PAC results. Thirty-five of the 36 patients with a positive PAC had histologically proven appendicitis. Seven of the 11 patients with a negative result had normal appendices. The sensitivity of PAC for acute appendicitis was 85% and the specificity was 70%. The positive predictive value was found to be 97% and the negative predictive value 60%. Peritoneal aspiration cytology is a useful aid in the diagnosis of acute appendicitis however, a negative result does not exclude this diagnosis.
51例临床诊断为急性阑尾炎的患者接受了腹腔穿刺细胞学检查（PAC）。36例结果为阳性，11例为阴性，4例穿刺失败。所有患者均接受了阑尾切除术，组织学检查结果与PAC结果相关。36例PAC阳性的患者中，35例经组织学证实为阑尾炎。11例阴性结果的患者中，7例阑尾正常。PAC对急性阑尾炎的敏感性为85%，特异性为70%。阳性预测值为97%，阴性预测值为60%。腹腔穿刺细胞学检查对急性阑尾炎的诊断有一定帮助，然而，阴性结果并不能排除该诊断。
