肝脏术中超声的临床价值

目的总结肝脏术中超声的优越性,准确诊断病变,提高原发性肝肿瘤的手术切除率。方法采用高频率５．０ＭＨｚ探头,探头置于肝表面,观察肿物大小、数量、部位与血管的关系。结果４２例原发性肝肿瘤,２９例经术中超声定位后切除肿瘤;４例术中超声发现肿物与大血管关系密切,无法切除;６例术中发现多发病灶。结论术中超声较经腹超声和术中探查敏感,其优越性为：（１）定位准确,能提高手术切除率;（２）可确定肿瘤与血管关系;（３）弥补术前影像检查的不足;（４）术中可进行肝脓肿开窗术及肝囊肿介入治疗。

The clinical value of intraoperative ultrasound of the liver

Objective To evaluate usefulness of intraoperative ultrasound of the liver. Methods A 5.0 MHz ultrasound transducer was used to detect liver lesions, their number, location and relation to the intrahepatic blood vessels. Results Forty two patients with primary liver tumors received intraoperative ultrasonographic examination. Liver tumor was resected in 29 patients(69.0%). The tumors in 4 patients were unresectable due to their close relationship to the hepatic vasculature as judged by the ultrasound image. Multiple lesions were found in 6 patients during operation. Conclusions Intraoperative ultrasound of the liver is sensitive enough to detect most liver lesions and to locate them by liver segment which makes radical tumor resection possible. It is useful to define the tumor in relation to hepatic vasculature. It can compensate for missing lesions in preoperative imaging studies. Fenestration operation for liver abscess and intervention treatment for liver cysts can be performed during operation.
