目的评估腔内水囊磁共振成像(MRI)预测直肠癌术前分期的准确程度.方法回顾性分析19例直肠癌患者的临床资料,对照术前MRI和术后病理结果,评估MRI能否准确预测直肠癌T和系膜淋巴结转移(N)分期.结果 MRI正确T分期15例(78.9%),错误4例,其中2例T1～2期报告为T3期,2例T3期报告为T1～2期;T1～2期的准确率为80%(8/10),T3期的准确率为7/9.MRI正确N分期11例(57.9%),错误分期8例;其中高估2例,低估6例,灵敏度为3/9,特异度为80.0%(8/10).结论术前腔内水囊MRI不能对直肠癌系膜淋巴结转移做出准确预测,可以对T分期进行一般预测.

Objective To evaluate the accuracy of preoperative magnetic resonance imaging (MRI) with water-bag in rectum in prediction of pathological staging of rectal cancer. Methods Clinical data of 19 patients with rectal carcinoma assessed by MRI with water-bag in rectum for tumour (T) and mesorectal nodal (N) staging were analyzed retrospectively. Preoperative MRI assessment was compared with postoperative histopathological findings. Results The tumors were correctly staged by MRI in 15 patients, understaged in 2 and overstaged in 2. The accuracy of T stage was 78.9%(15/19). Mesorectal node were correctly staged in 11 patients, overstaged in 2 and understaged in 6.The accuracy of node staging was 57.9% (11/19), sensitivity was 3/9, and specificity was 80%(8/10).Conclusion Preoperative MRI with water-bag in rectum can not provide correct predictive data on mesorectal node stage, but has certain value in the T staging of rectal carcinoma.
