Core tip: The revised Atlanta classification of acute pancreatitis was approved by international consensus, and is based on actual local and systemic determinants of disease severity. Local complications of pancreatitis can include acute peri-pancreatic fluid collection, acute necrotic collection, pseudocyst formation, and walled-off necrosis. Interventional endoscopic ultrasound (EUS) has been increasingly utilized in managing pancreatitis. This review describes the utility, efficacy, and risks associated with using therapeutic EUS and involved EUS devices to manage acute pancreatitis. The authors propose an algorithm for use in managing pancreatic fluid collections based on their size, location, associated symptoms, internal echogenic patterns, and content.
