Pancreatic cysts have many histological subtypes. With development of imaging techniques such as computed tomography and magnetic resonance imaging, detection rate of pancreatic cysts has been increasing. And standardized diagnosis and treatment of pancreatic cysts remains a clinical challenge. Due to insufficient understanding of imaging features and tumor markers of pancreatic cysts, a reasonable procedure of diagnosis and treatment has not been published so far. Several guidelines for the diagnosis and treatment of pancreatic cysts with high impact have been published, including international consensus guidelines, European experts consensus statement and American Gastroenterological Association guidelines. This review focused on the diagnosis and treatment strategies and suggestions proposed by the above guidelines, and application of endoscopic ultrasonography, so as to provid references for treatment of pancreatic cysts.
