活动期溃疡性结肠炎MSCT表现与Mayo评分的相关性

Multi Slice Computed Tomography Enteroclysis Assessment of Active Ulcerative Colitis: Correlation with Mayo Score

目的探讨多层螺旋CT肠道造影(CTE)在活动期溃疡性结肠炎病情评估中的价值。方法搜集46例溃疡性结肠炎患者的临床及CTE检查资料,对每例患者的CTE表现进行综合评分,分析CTE评分与Mayo评分的相关性。临床病情的严重程度采用改良Mayo评分系统,依据评分结果分成轻度、中度、重度三组。对三组间CTE的评分差异行统计学检验。结果 Mayo系统评分,46例中,轻度组10例,中度组17例,重度组19例。三组的CTE评分分别为4.9±2.3、7.6±2.6、10.9±2.0,各组之间的差异具有统计学意义(P<0.01)。溃疡性结肠炎的CTE评分与改良Mayo评分两者之间呈线性正相关(相关系数0.835)。结论 CTE评分法可准确地评估活动期溃疡性结肠炎病情的严重程度。

Objective To evaluate the utility of multislice computed tomography enteroclysis（ CTE） in assessing the severity of active ulcerative colitis（ UC）. Methods The clinical and CTE data of 46 patients diagnosed as active UC were collected. CTE manifestations of each patient was scored comprehensively. The modified Mayo scoring criteria was adopted for clinical assessment of active UC. According to modified Mayo scoring criteria,the patients were divided into 3 groups： mild,moderate and severe group. The differences of CTE scores among these groups were analyzed statistically.Results There were 10 patients in mild group,17 in moderate group and 19 in severe group. The average CTE score of each group was 4. 9 ± 2. 3,7. 6 ± 2. 6,and 10. 9 ± 2. 0 respectively,with significant differences among the three groups（ P 〈0. 01）. The CTE and modified Mayo scores demonstrated significant correlation（ the Spearman＇s correlation coefficient was 0. 835）. Conclusion The clinical severity of active UC can be assessed accurately by CTE scoring method.
