title: Clinical application of peroperative ultrasonography in liver surgery.
abstract: This communication outlines the findings at peroperative ultrasonography in patients who had resectional liver surgery because of primary hepatocellular carcinoma. Peroperative ultrasonography revealed the accurate location of the tumor, its relation with locoregional vascular structures, presence of tumor metastases and tumor thrombus. Additionally, ultrasonography provided useful guidance for tumor resection by making possible tumor staining via echo-guided puncture of the feeding vessel of the tumor.
