In 1992, the Atlanta classification for acute pancreatitis was introduced as a universally applicable classification system for the various manifestations of acute pancreatitis . This system was designed to facilitate understanding and correlation of findings seen by gastroenterologists, pathologists, radiologists, and surgeons. This approach was to be particularly useful for assessment and treatment of the various fluid collections identified during the course of acute pancreatitis. It defined acute pancreatitis as an acute inflammatory process of the pancreas with variable involvement of other local tissues and remote organ systems.
This initial Atlanta classification system represented major progress, but advancing knowledge of the disease process, improved imaging, and ever-changing treatment options such as minimally invasive radiologic, endoscopic, and laparoscopic procedures soon rendered some of the definitions inadequate or ambiguous , presenting a need to revise and update the Atlanta classification. The revision in 2012 places major emphasis on revised on new criteria for pancreatic fluid collections and revises some of the clinical criteria and terminology.
To learn how imaging should be scheduled (or not) for patients with acute pancreatitis
To become familiar with the imaging features and the new terminology proposed in the revised 2012 Atlanta classification
To discuss the remaining limitations of the 2012 Atlanta Classification
The goal is for radiologists, gastroenterologists, surgeons, and pathologists to use the revised classifications to standardize imaging terminology to facilitate treatment planning and enable precise comparison of results among different departments and institutions.
