Abstract

This research aims to classify patients with acute pancreatitis into interstitial edematous pancreatitis and necrotizing pancreatitis using the updated Atlanta classification and to describe the types of collections found in these patients using contrast-enhanced computed tomography. Materials and Methods: This was hospital-based prospective observational research. The study period began June 2022 to May 2023, conducted at the Department of Radio Diagnosis, General Medicine, General Surgery at Chettinad Hospital and Research Institute, Kelambakkam, Tamil Nadu. 100 patients made up the study's sample size. The researcher gathered primary data from individuals hospitalized to the surgery or medicine wards with the diagnosis of acute pancreatitis. Results: The study cohort consisted of male patients, with Alcohol consumption identified as the predominant etiological factor contributing to their medical state. Furthermore, the prevalence of interstitial edematous pancreatitis and mild acute pancreatitis was found to be significantly higher in the majority of patients. Both acute necrotizing pancreatitis and interstitial edema were categorized as quite severe. Necrotizing pancreatitis emerged as the predominant manifestation of the highly severe acute variant. The majority of these people experienced unfavorable clinical results. Grades falling within the moderately severe range are situated between those classified as mild and severe. Conclusion: The new Atlanta classification system makes it easier to describe and document imaging findings in cases of acute pancreatitis in clinical settings. The revised Atlanta classification and BISAP clinical grading have been integrated to improve the triage, prediction, and treatment of patients with acute pancreatitis.
