A total of 213 patients with carcinoma of the colon and rectum were examined to detect liver metastases. The study compared preoperative ultrasonography and inspection and palpation of the liver during surgery with intraoperative ultrasonography. Preoperative ultrasonography, inspection and palpation identified 238 metastases in 42 patients. Intraoperative ultrasonography detected 116 previously unrecognized metastatic tumours during 40 surgical procedures (P less than 0.01). High resolution intraoperative ultrasonography is safe and more accurate than preoperative imaging and surgical exploratory methods. The examination is simple to perform and success appears to be related to careful attention to detail.
对总共213例结肠直肠癌患者进行了检查，以检测肝转移情况。该研究将术前超声检查以及手术中对肝脏的视诊和触诊与术中超声检查进行了比较。术前超声检查、视诊和触诊在42例患者中发现了238处转移灶。术中超声检查在40例手术过程中检测到了116个先前未被识别的转移瘤（P<0.01）。高分辨率术中超声检查安全，且比术前成像和手术探查方法更准确。该检查操作简单，其成功似乎与对细节的仔细关注有关。
