BACKGROUND/AIM: Determining the severity of acute pancreatitis (AP) is crucial for patient management. The aim of our study was to assess the accuracy and limitations of the Revised Atlanta Criteria (RAC) in determining the severity of AP. MATERIALS AND METHODS: The study was retrospectively conducted on AP patients admitted to the Gastroenterology Department of Sakarya University Faculty of Medicine. The severity, morphology and local complications of AP were evaluated according to the RAC. Laboratory parameters, clinical scores predicting disease severity and Computer Tomography Severity Index scores were assessed. RESULTS: The study group included 113 patients. Ninety-eight (86.7%) had interstitial edematous, and 15 (13.3%) had necrotizing pancreatitis. AP pancreatitis was mild in 69 (61.1%), moderate in 33 (29.2%), and severe in 11 (9.7%). Compared to the moderate group, patients in the severe group had a higher hematocrit, creatinine, SIRS and BISAP scores at admission and more length of hospital stay, more ICU requirements, and higher mortality rates ( P < 0.05). Eleven patients had single or multiple persistent organ failure (POF). The mortality rate of patients who developed early POF (n = 6) was higher compared to the group of patients who developed late POF (n = 2) (83.3% and 40%, respectively). CONCLUSION: Severity assessment using the RAC in patients with AP is consistent with laboratory parameters and scoring systems predicting severity. Severe pancreatitis cases who develop early POF may be classified separately.
