The aim of this study was to compare the accuracy of intra-operative ultrasound (IOUS) with other imaging modalities and with surgical palpation in detecting liver metastases from colorectal cancer (CRC). Intra-operative ultrasound was performed in 100 patients undergoing surgery for CRC. All patients had pre-operative liver function tests, transcutaneous ultrasound and computerized tomography (CT) scan of the liver. The liver was palpated intra-operatively by a surgeon who was unaware of the pre-operative findings. The liver was then assessed by IOUS. Intra-operative ultrasound detected more patients with metastases than either CT scan, transcutaneous ultrasound or surgical palpation. It also detected a greater number of smaller metastases in these patients and allowed better anatomical definition compared with pre-operative investigations.
本研究的目的是比较术中超声（IOUS）与其他成像方式以及手术触诊在检测结直肠癌（CRC）肝转移方面的准确性。对100例接受CRC手术的患者进行了术中超声检查。所有患者术前行肝功能检查、经皮超声检查和肝脏计算机断层扫描（CT）。由一名不知道术前检查结果的外科医生在术中对肝脏进行触诊。然后通过IOUS对肝脏进行评估。与CT扫描、经皮超声或手术触诊相比，术中超声检测出更多有转移的患者。它还在这些患者中检测到更多数量的较小转移灶，并且与术前检查相比，能更好地进行解剖定位。
