Introduction: In our study, we aimed to evaluate how age affects the severity and course of acute pancreatitis according to the modified Balthazar scoring system.Materials and methods: 354 patients diagnosed with acute-pancreatitis and followed-up in our hospital between July/2013-February/2019 were included our study. Demographic data, comorbid diseases and mortality rates of all patients were documented. Patients with aged 65 and over were assessed as geriatric population. Allpatientsincludedinthestudyunderwentcontrastenhancedabdominalcomputed-tomography within the first 12 hours and on days 3 to 7. According to the modified Balthazar score, patients with mild, moderate and severe acute-pancreatitis respectively. The relationship between age and computed-tomography findings was analyzed. Results: 206 (58.2%) of the patients included in the study were women. Mean age was 54.8±17.9 years (18-100 years). Geriatric population consisted of 129(36.5%) patients. There was no statistically significant difference between the two groups accordingtothemodifiedBalthazarclassificationontheinitialcomputed-tomographies on admission (p>0.05). However, on computed-tomography scans taken after the third day, severe acute-pancreatitis was detected significantly more frequently in the elderly (p<0.05). Additionally, in comparing the disease progression on computed-tomography scans, disease progression was significantly higher in the elderly group (p <0.05). In addition, comorbidity score and mortality rate were found to be significantly higher in the elderly group (p<0.001, p:0042, respectively).Conclusion: In acute pancreatitis, age may have an effect on the severity of the disease. For this reason, multidisciplinary approach and close follow-up with monitoring is crucial in geriatric patients.
