结、直肠癌患者首次手术时,术前超声检查和术中视诊、触诊探查发现有肝转移癌者可达15～20%。现在,术中超声检查已用于肝脏手术。结、直肠癌患者术中超声检查肝脏有无转移癌、肝转移癌数目、部位、大小、深度及其和肝内血管相互关系,提高肝转移癌诊断准确性,并有助于相应的治疗分析。作者(挪威)于1987～1989两年期间收治结、直肠癌患者213例,经术前超声、手术视诊触诊探查和术中高分辨力实时显像超声、高频(7 MHz)探头检查,均未发现肝转移癌者共150例(占70.4%),其余63例
When patients with colorectal cancer and rectal cancer were first operated, preoperative ultrasonography, intraoperative visual inspection, and palpation detection revealed that 15 to 20% of patients had liver metastases. Intraoperative ultrasound has now been used for liver surgery. Intraoperative ultrasound examination of colorectal cancer patients with or without liver metastases, the number, location, size, depth of liver metastases and their relationship with intrahepatic vessels, improve the diagnostic accuracy of liver metastases, and contribute to the appropriate treatment analysis . The authors (Norway) treated 213 patients with colorectal cancer and rectal cancer between 1987 and 1989. They were examined by preoperative ultrasound, surgical examinations, and high-resolution real-time imaging ultrasound and high-frequency (7 MHz) probes. No liver metastases were found in 150 patients (70.4%), and the remaining 63 patients
