[摘 要]  目的: 对比Ranson 评分及Balthazar CT严重指数（CT severity index，CTSI）评价急性胰腺炎严重程度床边指数(BISAP评分）预测急性胰腺炎(Acute pancreatitis, AP)严重程度及预后的价值。方法: 联合上海地区7家医院，收集7年间共1004例急性胰腺炎患者的临床资料, 进行回顾性分析。采用受试者工作特性曲线分析BISAP评分、Ranson 评分及CTSI预测AP的病情严重程度、预后的价值。结果: 1004例患者中, SAP发生率、胰腺坏死发生率和死亡率均随着BISAP评分的增加而升高。三类评分预测急性胰腺炎病情进展及死亡的准确性间无统计学差异，但BISAP评分预测胰腺炎进展及死亡率敏感性优于Ranson及CTSI评分。结论: BISAP评分操作简单，结合CTSI有助于及时对急性胰腺炎作出诊断和分型，能在早期准确地判断转归，预测预后，较Ranson评分更具临床应用价值。

【Abstract】Objective  To compare the value of BISAP score, Ranson score and Balthazar CTSI in predicting the severity and prognosis in acute pancreatitis.

Method  A retrospective study was carried out in 1004 cases of acute
pancreatitis in 7 hospitals from 2005 to 2011 in Shanghai. The value of BISAP score , Ranson score and Balthazar CTSI were assessed using receiver operator characteristic(ROC) curve in predicting the severity and prognosis of the disease.

Results 
In this group of patients, the incidence of pancreatic necrosis,
mortality and SAP increases along with BISAP score. The accuracy in the
prediction of the mortality of acute pancreatitis had no significant difference among these three score systems. However BISAP score had the highest sensitivity in prediction of mortality.

Conclusion 
BISAP score is easy to obtain and with the combination of CTSI, is
suitable for current clinical practice, it can provide accurate information for
the diagnosis and classification of AP on time, and also can predict the severe cases in the early stage.
