      【摘要】 目的 探讨高频、低频彩色多普勒超声检查联合血浆降钙素原(PCT)对阑尾炎的诊断价值。方法 选择2019年1月至2020年12月东莞市企石医院收治的临床疑似阑尾炎患者50例，行手术治疗，接受高频与低频彩色多普勒超声检查，并检测其血浆PCT水平，以病理检查为金标准，比较高频、低频彩色多普勒超声、血浆PCT单一检查与联合检查方式对阑尾炎的诊断价值。结果 50例疑似阑尾炎患者手术病理检查均为阳性；低频彩超检查显示真阳性41例、假阳性0例、真阴性0例、假阴性9例；高频彩超检查显示真阳性42例、假阳性0例、真阴性0例、假阴性8例；血浆PCT检测显示真阳性 17例、假阳性 0例、真阴性 0例、假阴性 33例；三者联合检查显示真阳性 48例、假阳性0例、真阴性0例、假阴性2例。低频彩超诊断准确度、敏感度均为82.00%，高频彩超诊断均为84.00%，血浆PCT诊断均为34.00%，联合诊断均为96.00%，联合诊断分别与低频、高频超声及血浆PCT检查比较差异有统计学意义(P<0.05)。结论 高频、低频彩色多普勒超声检查对诊断阑尾炎疾病均具有一定价值，但三者联合诊断价值更高，临床应根据实际情况选择最佳诊断方法。

【Abstract】 Objective To explore the diagnostic value of high-frequency and low-frequency color doppler ultra-sonography combined with plasma procalcitonin (PCT) in appendicitis.Methods Fifty patients with suspected appendici-tis admitted to Dongguan Qishi Hospital from January 2019 to December 2020 were selected for surgical treatment. All pa-tients were examined by high-frequency and low-frequency color doppler ultrasonography, and the level of plasma PCTwas detected. Taking pathological examination as the gold standard, the diagnostic value of high-frequency and low-fre-quency color Doppler ultrasound, plasma PCT single examination and combined examination in appendicitis was com-pared. Results Fifty patients with suspected appendicitis were positive by surgical and pathological examination. Low-fre-quency color Doppler ultrasound examination showed true positive in 41 cases, false positive in 0 case, true negative in 0case, false negative in 9 cases. High-frequency color Doppler ultrasound examination showed true positive in 42 cases,false positive in 0 case, true negative in 0 case, false negative in 8 cases. Plasma PCT showed true positive in 17 cases, falsepositive in 0 case, true negative in 0 case, false negative in 33 cases. The combined examination of the three showed truepositive in 48 cases, false positive in 0 cases, true negative in 0 cases and false negative in 2 cases. The diagnostic accuracyand sensitivity for low-frequency color Doppler ultrasound were both 82.00%, 84.00% for high-frequency color Dopplerultrasound, 34.00% for plasma PCT, and 96.00% for combined diagnosis. There was significant difference between com-bined diagnosis and low frequency, high frequency ultrasound and plasma PCT (P<0.05). Conclusion High-frequencyand low-frequency color Doppler ultrasonography have certain value in the diagnosis of appendicitis diseases, but the com-bined diagnostic value of the three is higher. The best diagnostic method should be selected according to the actual situa-tion in clinic.
