Tóm tắt

AbstractThe development of diagnostic equipment for sonography has not only caused a marked improvement in the preoperative diagnostic rate of primary carcinoma of the liver, but also has enabled us to conduct sonography during operations.During the past 2 years, intraoperative sonography was used in 41 cases of primary carcinoma of the liver. The main tumor was detected in 39 patients (95.1%), and daughter tumors were detected in 14 (63.6%) out of the 22 who had them. Tumor thrombi in the portal vein were detected in 2 (50%) of the 4 patients in whom they occurred.Since intraoperative sonography can clearly demonstrate intrahepatic ductal structures, it is useful for identification of hepatic and portal veins and the subsegment containing tumors (by a sonographically guided puncture). Of the various kinds of medical imaging available to us, intraoperative sonography is the final diagnostic procedure used before the last details of the operation are decided.
