Three scoring systems in evaluating the condition and prognosis of acute pancreatitis

Objective: To investigate the application value of three scoring system,namely APACHEⅡ,Ranson and BISAP in the assessment of the severity and prognosis of acute pancreatitis. Methods: The clinical data of 128 patients with acute pancreatitis in our hospital were retrospectively analyzed and graded respectively by using APACHEⅡ,Ranson,and BISAP systems. Concerning the three different systems,their working characteristics( ROC curve) were compared. The correlation between the evaluation and fasting time and hospitalization time was analyzed. Results: All of the three scoring systems showed a significant correlation with fasting time and length of hospital stay. APACHE Ⅱ score system had advantages in evaluating the degree of illness and systemic complications. A higher Ranson score than 5 points could be used as an ideal prediction of local complications. A higher BISAP score than 3 points could be used as a reasonable prediction of mortality. Conclusion: All of the three scoring systems are able to evaluate the condition and prognosis of AP. APACHEⅡ system can better evaluate the degree of AP and systemic complications,but has faults in the prognosis of local complications; Ranson system shows a good effect on the prediction of the local complications but fails to assess the systemic complications and mortality. As for BISAP system,it has an advantage in evaluating the mortality of patients but not in assessing the degree and prognosis of AP.
