摘要
目的 评估术中超声 (OUS)在诊断肝内胆管结石中的应用价值。方法 运用Toshiba60 0 0术中超声探头于手术过程中对 98例术前彩超检查诊断为肝内胆管结石的患者进行检查 ,并与最后手术结果及病理结果相比较。结果 98例患者中 ,术中超声诊断 90例为肝内胆管结石 ,5例为胆泥淤积 ,3例为胆管炎症伴管壁纤维化 ,并在 7例中发现术前未检查出的肝内胆管结石 ,1例出现癌变 ,与手术结果与病理结果完全符合。结论 术中超声探头频率较高 (7-1 0MHz) ,具有较高的分辨率 ,且直接置于肝脏表面扫查 ,具有更高的诊断准确率 ,可纠正术前超声检查的误诊与漏诊 ;而且术中超声定位准确 ,并能对手术实时动态地进行监测 ,指导手术进行 ,检查手术效果。因此 ,术中超声特别是“首次扫查”
Objective To evaluate the value of intra-operative ultrasound (OUS) in the diagnosis of hepatolithiasis. Methods Ninety eight patients with hepatolithiasis diagnosed by color Doppler ultrasound before operation were examined by Toshiba 6000 during the operation and the results were compared with those of the operation and pathology. Results Among the 98 patients examined by OUS, hepatolithiasis was confirmed in 90 cases, biliary sludge in 5 cased, and cholangitis with fibrosis of dissepiments in 3 cases. Some stones that hadn't been found before operation were detected by OUS in 7 cases, and cancer of hepatic duct was diagnosed in 1 case. The results above were coincident with those of operation and pathology entirely. Conclusions The intraoperative probe has higher frequency (7-10 MHz) and higher resolution and it is placed on the surface of the liver directly, so it can redress the misdiagnosis and missed diagnosis before operation. OUS can direct the operation and check its effect by real time monitoring. So OUS, especially 'the first scan' can be a routine examination during the operations of hepatolithiasis.
