急性胰腺炎累及胃裸区与CT严重指数的相关性研究

Correlative study of gastric bare area involvement with CT severity index in acute pancreatitis

目的探讨急性胰腺炎(Acute pancreatitis,AP)时胃裸区受累(Gastric bare area Involvement,GBAI)分级与AP影像分级(CTSI)的相关性。方法回顾性分析112例连续性AP患者的螺旋CT资料及临床资料,使用GBAI分级标准对GBA受累进行分级,使用CT严重指数(CT Severity Index,CTSI)对AP进行影像分级,然后使用等级相关检验对AP时GBAI分级与CTSI分级进行统计学检验,计算二者的相关性系数。结果AP时GBAI分级与CTSI分级的相关性系数=0.729,P<0.001;具有统计学意义,二者有正相关性。结论AP时GBAI分级与影像学分级(CTSI)有正相关性。在全面评价AP的严重程度时,GBA受累程度在一定程度上可以作为评价其严重程度的一个重要辅助指标。

Objective To investigate the correlation between the grading of gastic bare area involvement （GBAI） and the CT severity index （CTSI） in acute pancreatitis （AP）. Methods CT scannings and clinical data of 112 consecutive patients with AP were studied retrospectively. The involvement of GBA and CTSI score of AP were graded using GBA involvement criteria and CT severity index （CTSI） criteria respectively. The grade of GBAI in AP was correlated with the grade of CT severity index （CTSI） by way of Ranking Test. Results The Pearson Correlation coefficient of morphologic grade of GBAI in AP correlated with CTSI severity classified by CTSI was 0.729, and its P 〈0.001, which indicated the statistic value between these two grading systems. Conclusion GBAI in AP is strongly correlated with CTSI and can be used as a supplementary criteria to the CTSI criterion to evaluate thoroughly the range, degree and severity of the AP.
