Occult hepatic metastases (OHM) from colorectal cancer are those not evident to the surgeon at laparotomy. In this retrospective and "deductive" study the Authors evaluated the accuracy of hepatic CT scan and ultrasonography (US) to detect hepatic metastases. The CT and US accuracy rate was 78.4% and 79.8% respectively, and proved to be correlated to the intraoperative dimensions of the lesions. Sensitivity of these examinations, in the light of OHM identification, decreased to 69% and 69.2% respectively. This study shows that hepatic US and CT scan are not sufficient to identify OHM; the attempt to reduce the frequency of OHM by means of intraoperative ultrasonography could allow to obtain a more careful stadiation and prognosis of these neoplasms with possible therapeutic advantages.
结直肠癌的隐匿性肝转移（OHM）是指在剖腹手术时外科医生无法发现的转移灶。在这项回顾性“演绎”研究中，作者评估了肝脏CT扫描和超声检查（US）检测肝转移的准确性。CT和US的准确率分别为78.4%和79.8%，并被证明与病变的术中大小相关。鉴于OHM的识别，这些检查的敏感性分别降至69%和69.2%。这项研究表明，肝脏超声检查和CT扫描不足以识别OHM；通过术中超声检查试图降低OHM的发生率，可能会对这些肿瘤进行更仔细的分期和预后评估，并可能带来治疗优势。
