摘要
目的探讨术前螺旋CT在大肠癌诊断和分期中的价值。方法对87例经手术病理证实的大肠癌,分析术前螺旋CT表现,与手术及病理分期对照,了解大肠癌的螺旋CT分期的敏感性、准确性。结果螺旋CT能显示肠腔及肠壁的改变、病灶与周围组织关系,并可显示周围组织器官的侵犯及有无远处转移。本组螺旋CT显示大肠癌的敏感性达100%(87/87),对大肠癌TNM分期的准确率为T分期92%(80/87),N分期93.1%(81/87),M分期100%。结论大肠癌术前螺旋CT检查对大肠癌诊断和分期具有重要意义,是目前临床评估大肠癌术前分期的最佳影像方法。
Objective To study diagnosis and staging of spiral CT in colorectal carcinoma. Methods The preoperative CT imaging of 87 patients with colorectal carcinoma were analyzed retrospectively.The results were compared with those of surgery and pathological examination in 87 cases in order to study the sensitivity and accuracy of CT staging. Results The spiral CT showed the changes of lumen and wall, and the relationship between the lesions and adjacent tissues. It could also detect the invasion of adjacent tissues and distant metastasis. All the lesions of 87 cases were demonstrated clearly by spiral CT and the sensitivity was 100%. 80 cases of 87 (92%) were correctly staged with T, 81 of 87 (93.1%) with N, and all the cases (100%) with M. Conclusion The preoperative spiral CT examination is helpful in the diagnosis and staging of colorectal carcinoma.
