摘要
目的探讨术中超声在肝脏肿瘤手术中的应用价值及其优势。方法对65例肝脏肿瘤患者行术前经腹超声(TAS)、CT和术中超声(IOUS)对比分析,以评价IOUS和术前影像学检查的差异,并评价术中超声在手术过程中的价值。结果 65例肝脏肿瘤患者共有93个肿瘤病灶,IOUS、TAS和CT的敏感度分别为97.85%、86.02%和91.40%,尤其是微小病灶IOUS明显优于TAS和CT(P<0.05);特异度分别为95.70%、81.72%和93.55%,IOUS明显优于TAS(P<0.05);IOUS发现新病灶6个,并精准定位12个术中无法触及的小病灶和辅助13例脉管内癌栓取出。结论 IOUS相比于TAS和CT具有更高的敏感度及其特异度优于TAS,并且对术者具有良好的指导作用。
Objective To explore the value and advantage of introperative ultrosound in liver neoplasm surgery. Methods The examination results were comparely studyed with transabdominal ultrsonography （TAS） and computed tomo- graphy （CT）on 65 cases, in order to evaluate the difference between IOUS and TAS or CT, and to assess the value of introperation uhrosound during operation procedure. Results There were 93 tumors in 65 cases. The sensitivity of IOUS,TAS and CT were 97. 85% ,86.02% and 91.40% respectively, especially the sensitivity of IOUS was higher than that of TAS and CT（ P 〈 0. 05） for small-sized tumor with diameter≤2. 0 cm. The specificity were 95.70% ,81.72% and 93.55% for IOUS,TAS and CT respectively, and there was significative difference between IOUS and TAS （ P 〈 0. 05 ）. In this study, 6 new tumors were found, 12 tumors which surgeon didn＇ t find by paipating could be orientated by IOUS and helped surgeon to weed out the cancer tissue in blood vessel or bile duct in 13 cases. Conclusion IOUS is more sensitive than TAS and CT,has higher specificity compared with TAS,and could guide surgery during operation.
