[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.
