A multi-center retrospective study on the judgment value of bedside index for severity in acute pancreatitis / 中华消化杂志

ABSTRACT

Objective To compare the value of bedside index for severity in acute pancreatitis (BISAP),Ranson score and Balthazar computed tomography severity index (CTSI) in predicting the severity and prognosis of acute pancreatitis (AP).Methods From 2005 to 2011 in Shanghai,the clinical data of 1004 AP cases from seven hospitals was collected and retrospectively analyzed.The value of BISAP score,Ranson score and Balthazar CTSI in predicting the severity and prognosis of AP were assessed with receiver operator characteristic (ROC) curve.Results Among 1004 patients,the main cause of AP was biliary disease (580 cases),about 57.77％.The incidence of pancreatic necrosis,mortality and SAP increased along with BISAP score.The risk of pancreatic necrosis in patients with CTSI ≥ three was significantly higher than that of ＜ three.The risk of pancreatic necrosis and SAP in patients with BISAP score ≥ two was significantly higher than that of ＜ two (OR4.93,95％CI 3.62-6.70; OR 2.62,95％CI 1.59-4.31,respectively).There was no significant difference in the accuracy of predicting the progression and mortality of AP among these three score systems.However the sensitivity of BISAP score (OR61.54,95％CI 35.09-87.99) in predicting the progression and mortality of AP was better than that of Ranson (OR46.15,95 ％ CI 19.05-73.25) and CTSI (OR46.15,95％CI 19.05-73.25).Conclusions BISAP score is easy to perform and when combined with CTSI,it helps to make the diagnosis and classification of AP in time,predict the prognosis accurately.Compared with Ranson score,BISAP score has higher clinical value.
