Abstract:

Objective: In our study, the correlation between computed tomography severity index (CTSI) and modified computed tomography severity index (MCTSI) regarding assessment of severity parameters in acute pancreatitis, and Ranson criteria were investigated. Patients and Methods: The study was retrospective and included 50 patients. Demographic, clinical and laboratory data were recorded. The size of the pancreas, peripancreatic inflammation, pararenal fascia thickening, necrosis, abscess, lymphadenopathy and abdominal ascites were investigated by computed tomography (CT) imaging. According to the data obtained, the CTSI and MCTSI values of each patient were calculated. The severity parameters of the disease; age, duration of hospitalization, abscess, pleural effusion and death were determined. Biliary, non-biliary pancreatitis and Ranson criteria were calculated. Results: In both groups and subgroups (mild, moderate and severe), there were no significant differences regarding age, hospital stay, gender and pleural effusion. but significant differences were detected for the presence of abscess and distribution of death. To determine compliance with each three subgroups in both scoring systems, Kappa test was used but the results were not consistent. No statistically significant correlation was observed between CTSI and MCTSI and Ranson scores. Conclusion: Our study shows that the CTSI and MCTSI are significantly correlated with mortality and abscess detection rate, only MCTSI is significantly correlated with the duration of hospitalization. Both of the severity indexes are not correlated with each other and Ranson Score
