目的比较腔内超声(EUS)和螺旋CT(SCT)对直肠癌术前分期的诊断价值。方法对68例直肠癌患者术前行EUS和SCT检查,将检查结果与手术及病理结果对比；同时比较EUS和SCT对诊断直肠肿瘤浸润深度、区域淋巴结转移的准确性。结果判断T分期,EUS准确率为86．8%(59/68),SCT准确率为70．6%(48/68),两者比较差异有统计学意义(P＜0．05)。评价N分期,EUS的准确率为67．6%(46/68),SCT的准确率为63．2%(43/68),两者比较差异无统计学意义(P＞0．05)。结论EUS对判断直肠肿瘤浸润深度优于SCT,但两者对淋巴结转移的判断均存在一定的局限性。
Objective To compare the diagnostic value of intracavitary ultrasound (EUS) and spiral CT (SCT) in the preoperative staging of rectal cancer. Methods Sixty-eight patients with rectal cancer underwent preoperative EUS and SCT examinations. The results of the examinations were compared with the results of surgery and pathology. The accuracy of EUS and SCT in diagnosing rectal tumor invasion and regional lymph node metastasis was also compared. Results The accuracy of TUS was 86.8% (59/68) for EUS and 70.6% (48/68) for SCT. The difference was statistically significant (P <0.05). The accuracy of EUS was 67.6% (46/68) and that of SCT was 63.2% (43/68). There was no significant difference between the two groups (P> 0.05). Conclusion EUS is better than SCT in determining the depth of rectal tumor invasion, but both of them have some limitations in judging lymph node metastasis.
