Abstract
Acute pancreatitis is an inflammatory process of the pancreas, which can range from a localized inflammatory process to a systemic response, resulting in sepsis and multisystem failure. Pancreatic fluid collections are a complication of pancreatitis. Treatment of these fluid collections is dependent on correct classification. The 2012 Atlanta Criteria divides fluid collections into four categories: acute peripancreatic fluid collections, pancreatic pseudocysts, acute necrotic collections, and walled-off necrosis. Endoscopic ultrasound-guided management of chronic fluid collections is currently the preferred treatment modality. Endoscopy nurses need to be aware of their role in this treatment approach. Continued research in this area will lead to both advancements in equipment and treatment options.
