Introduction: There are various classifications for clinical presentation of acute pancreatitis. However, most of them are not standardised. Aims and Objectives: The revised Atlanta classification is designed to precisely describe patients with acute pancreatitis, standardise terminology across specialties and help in treatment planning. Materials and Methods: The revised Atlanta classification was analysed to describe the features of acute pancreatitis. Results: Acute pancreatitis is now divided into two distinct subtypes: necrotising pancreatitis and interstitial oedematous pancreatitis (IEP). Use of the terms such as acute pseudocyst and pancreatic abscess is currently being discouraged. Four distinct collection subtypes are identified based on the presence of pancreatic necrosis and the time elapsed since the onset of pancreatitis which include acute peripancreatic fluid collections, pseudocysts, acute necrotic collections (ANCs) and walled-off necrosis (WON). Conclusions: The updates in classification and terminology of local complications have clarified confusing terms from the original Atlanta classification. In this article, we report an image-rich guide to the revised Atlanta classification system to improve stratification of the patients both for clinical care and research.
