The aim of this study was to assess the utility of intraoperative ultrasound (IOUS) in the diagnosis and management of liver metastases from colorectal carcinoma. IOUS was performed on a consecutive series of 70 patients undergoing surgery for colorectal carcinoma, with follow-up ranging from 6 to 24 months. In ten cases (14.3%), 13 metastatic tumours were diagnosed; only six of these had been found by preoperative workup and/or surgical inspection. Seven (53.9%) small metastatic liver lesions were identified only by IOUS. None of the lesions diagnosed by IOUS was palpable, and they were all extremely small--ranging from 4 x 6 to 12 x 16 mm. Seventy-three locations were examined in order to compare the results of IOUS with those of other methods. The sensitivity of the former proved to be higher (P less than .05) than that of conventional pre- and intraoperative screening.
本研究的目的是评估术中超声（IOUS）在结直肠癌肝转移诊断和治疗中的效用。对连续70例接受结直肠癌手术的患者进行了IOUS检查，随访时间为6至24个月。在10例（14.3%）患者中，诊断出13个转移瘤；其中只有6个是通过术前检查和/或手术探查发现的。7个（53.9%）小的肝转移灶仅通过IOUS被识别。IOUS诊断出的病灶均不可触及，且都极小，大小从4×6毫米至12×16毫米不等。为了将IOUS的结果与其他方法的结果进行比较，共检查了73个部位。结果证明，IOUS的敏感性高于（P<0.05）传统的术前和术中筛查。
