Objective: The aim of this study is to investigate the effects of Procalcitonin and C-Reactive Protein (CRP) levels on hospitalization time and prognosis in patients diagnosed with acute pancreatitis.

Material and Method: In our crosssectional retrospective study, all patients who were admitted to the emergency department and diagnosed with acute pancreatitis and were admitted to our service within 3 years were evaluated for age, sex, alcohol use, presence of gallstones, Ranson score at arrival, procalcitonin and CRP levels at the first day of hospitalization, and their effects on the number of days of hospitalization and prognosis.

Results: One hundred and four patients were included in the study, 39 were male (37.5%), 65 were female (62.5%), and the mean age was 63.2 (min: 18-max: 97). There were biliary causes in 74 (71.2%) and nonbiliary causes in 30 (28.8%) of our patients. 4 of our patients (3.8%) died. There was a strong statistical difference in terms of age and Procalcitonin level between the two groups that we classified according to Ranson criteria, but there was no significant difference in terms of sex, CRP level, amylase level and day of hospitalization. Although CRP level was found higher in severe pancreatitis group, it was not statistically significant. In the Spearman correlation test, there was significant positive relationship between Ranson score, procalcitonin level and age; an insignificant positive relationship between Ranson score, CRP level, amylase level, and an insignificant negative relationship between Ranson score and length of hospital stay. A significant positive relation was detected between procalcitonin level and CRP level and between procalcitonin level and age.

Conclusion: Procalcitonin level can be used as an alternative to scoring systems in determining the severity and prognosis of acute pancreatitis.
