摘　　要：目的 比较分析经腹超声和手术中超声诊断方法,探索术中介入性超声治疗的可行性。 方法 应用便携式超声仪5MHz术中专用探头,对101例肝脏肿瘤住院作手术治疗患者行术中超声检查,并与术前经腹超声检查对比。 结果 术前经腹超声诊断正确83例,其中10例周围小病灶、7例门静脉癌栓漏诊,其完全符合率为65.3％(66/101);术中超声诊断符合率97％(98/101)。术中35.6％(36/101)的小病灶及静脉癌栓等探查中无法看见或触及,需借助于术中超声。 结论 术中超声由于分辨力高和扫查途径增加,可帮助微小病灶和隐匿性病灶检出,有助于手术治疗。Objective To compare the diagnostic methods of transabdominal and intraoperative ultrozsound (IOUS) in order to explore the feasibility of IOUS. Methods Intraoperative probe of 5 MHz was used to examine 101 patients with liver neoplasms who were admitted for surgical operation. The results of IOUS were compared with those of preoperative transabdominal ultrasound. Results Eighty-three cases of liver neoplasms were diagnosed by preoperative transabdminal ultrasound. However, 10 cases with satellite nodules and 7 cases with portal venous emboli were missed by transabdminal ultrasound. The diagnostic accordance rate of transabdominal ultrasound was 65.3%(66/ 101). IOUS detected 36 cases of small-sized lesions and portal venous emboli which couldn't be explored by operation. The diagnostic accuracy of IOUS was 97.0%(987 101). Conclusions IOUS is a useful method for detecting tiny lesion during operation due to its high resolution and the added scanning way.
