| 目的 评价螺旋CT对于结肠癌肝转移术前检出与可切除性评估价值。方法 螺旋CT扫描对100例肝转移病例进行术前分期,层厚5mm,重建间隔5mm;以2.0~3.0ml/s速率静脉注入100ml含碘造影剂后60~70s后开始扫描。螺旋CT征象与手术及病理所见按病灶逐一对照。结果 触诊与病理学检查揭示了184个肝转移灶,螺旋CT扫描正确预测了其中的156个,总体检出率84.8%,阳性预测值96.0%,假阳性率3.8%(7/184)。在72例患者的76例次手术中,71例次为可治愈切除,可切除率为93.4%(71/76)。病例五年生存率为54.2%。结论 螺旋CT扫描应被看作是结肠癌肝转移的标准或最佳术前检出方法。 |

| Objective To evaluate the value of spiral computed tomography (CT) in the preoperative detection of hepatic metastases and assessment of resectability. Methods During 1995-2002, preoperative staging with spiral CT was performed in 100 patients with hepatic metastases. Iodinated contrast material was injected intravenously (100ml; rate, 2-3ml/s). The scan was started at 60-70 seconds after the injection. Spiral CT findings were correlated with pathologic and surgical findings on a lesion-by-lesion basis. Results Palpation and histopathology examinations revealed 184 liver metastases; spiral CT correctly depicted 156 of them. Spiral CT results were as the following: overall detection rate was 84.8%; positive predictive value was 96.0%; and false-positive rate was 3.8% (7/184). Resection was recommended in 76 instances(72 cases) and curative resection was performed in 71 instances with a resectability rate of 93.4%(71/76). Five-year survival rate was 54.2%. Conclusion Spiral CT should be considered as the standard preoperative work-up of hepatic metastases from colorectal cancer. |
