摘　　要：目的探讨术中超声对肝肿瘤切除患者的应用价值。方法选择肝胆外科就诊的肝肿瘤患者,对患者做术前超声(preoperative ultrasonography, POUS)、CT及术中超声检查(intra-operative ultrasonography, IOUS),将患者的检查资料分为POUS组、CT组和IOUS组,再根据术后病理切片情况,比较以上三组检查对于不同直径范围的肝肿瘤的检出率,并对其做χ^2检验,筛选出对于肝肿瘤检出特异性最高的检查。结果 IOUS对于肝肿瘤的检出率达98.7%,显著高POUS(80.2%)及术前CT检查(87.7%)。同时,IOUS检查对于微小病灶及小病灶的检出敏感率同样高于其余两者,差异均具有统计学意义(P<0.05)。结论术中超声检查可以补充术前检查不足的信息,提高肿瘤检出率,减少肝肿瘤复发率,提高肝肿瘤切除患者的预后。Objective To explore the value of intraoperative ultrasound for patients with hepatic tumor resection.Methods Patients with liver tumors were enrolled from the hepatic surgery department of our hospital.Preoperative ultrasonography(POUS), CT, and intraoperative ultrasonography(IOUS) were performed on the patients respectively.According to the postoperative pathological biopsy, the detection rates of liver tumors in different diameter ranges were compared among the three groups, and the χ^2 test was performed to screen out the examination with the highest specificity for liver tumor.Results The detection rate of liver tumors by intraoperative ultrasound was 98.7%, significantly higher than the rates by preoperative ultrasound(80.2%) and preoperative CT examination(87.7%).At the same time, the sensitivity of intraoperative ultrasound examination for small lesions was higher than the other two, with significant differences(P<0.05).Conclusion Intraoperative ultrasonography can supplement preoperative information, improve the detection rate of tumors, reduce the recurrence rate of liver tumors, and improve the prognosis of patients with liver tumor resection.
