国家自然科学基金资助项目子课题 ( 394 70 2 2 1)目的 探究左膈下脂肪浸润 (leftsubphrenicfatinfiltration ,LSFI)与急性胰腺炎 (acutepancreatitis,AP)病情严重程度的相关性。方法 对能用Ranson、Balthazar标准进行分级的连续性AP病例 (分别为 1 4 4例、1 88例 )进行了回顾性的研究 ,对每例进行分级 ,并观测记录各病例的LSFI厚度 ,将 3mm以内的定为LSFI阴性 ,厚度记为 0。然后分别作每一例LSFI厚度与Ranson及Balthazar分级的等级资料的相关分析。结果 Ranson临床分级 1～ 3级中LSFI出现率分别为 30 86 % ,54 90 %及75 0 0 % ,LSFI厚度与Ranson分级的等级相关系数为 0 41 79,P <0 0 1 ;BalthazarCT分级A～E级中LSFI出现率分别为 0 ,0 ,31 52 % ,71 0 5 %及 80 76 % ,LSFI厚度与Balthazar分级的等级相关系数为0 630 1 ,P <0 0 1。结论 LSFI厚度与Ranson评分及Balthazar分级均呈显著正相关关系 ,可一定程度反映临床病变的严重程度及其扩展的范围
National Natural Science Foundation of China (394 70 2 2 1) Objective To investigate the relationship between the leftsubphrenicfatinfiltration (LSFI) and the severity of acute pancreatitis (AP). Methods A retrospective study was conducted on consecutive AP cases (114 cases, 1 88 cases) graded by Ranson and Balthazar criteria. Each case was graded and the LSFI thickness of each case was recorded. LSFI negative within 3mm, thickness 0. Then we analyzed the correlation between LSFI thickness and Ranson and Balthazar grading. Results The incidence rates of LSFI in Ranson grades 1 to 3 were 30%, 54% and 75%, respectively. The rank correlation coefficient between LSFI and Ranson grade was 0 41 79, P <0.01. BalthazarCT grade A The incidences of LSFI in grade ~ E were 0, 0, 31 52%, 71 0 5% and 80 76%, respectively. The correlation coefficient between LSFI thickness and Balthazar grade was 0 630 1, P 0 01. Conclusion There is a significant positive correlation between LSFI thickness and Ranson score and Balthazar grade, which can reflect the severity of clinical disease and its extent of expansion
