摘　　要：Pancreatic fluids collections are local complications related to acute or chronic pancreatitis and may require intervention when symptomatic and/or complicated.Within the last decade,endoscopic management of these collections via endoscopic ultrasound-guided transmural drainage has become the gold standard treatment for encapsulated pancreatic collections with high clinical success and lower morbidity compared to traditional surgery and percutaneous drainage.Proper understanding of anatomic landmarks,including assessment of the main pancreatic duct and any associated lesions–such as disruptions and strictures-are key to achieving clinical success,reducing the need for reintervention or recurrence,especially in cases with suspected disconnected pancreatic duct syndrome.Additionally,proper review of imaging and anatomic landmarks,including collection location,are pivotal to determine type and size of pancreatic stenting as well as approach using long-term transmural indwelling plastic stents.Pancreatography to adequately assess the main pancreatic duct may be performed by two methods:Either non-invasively using magnetic resonance cholangiopancreatography or endoscopically via retrograde cholangiopancreatography.Despite the critical need to understand anatomy via pancrea tography and assess the main pancreatic duct,a standardized approach or uniform assessment strategy has not been described in the literature.Therefore,the aim of this review was to clarify the role of pancreatography in the endoscopic management of encapsulated pancreatic collections and to propose a new classification system to aid in proper assessment and endoscopic treatment.
