Abstract: Pancreatic cystic neoplasm is a general term for a large class of pancreatic tumors, including mucinous cystic neoplasm, serous cystic neoplasm, and pancreatic intraductal papillary mucinous neoplasm. Due to the limitations of the current techniques in differential diagnosis and disease staging, different centers have great discrepancies in their treatment. The 103rd annual meeting of American College of Surgeons (ACS) as a grand meeting in the field of surgery bringed together a large number of clinical research results every year. Therefore, authors selected and reviewed contents about pancreatic cystic neoplasm, with a view to provide new ideas in terms of its management and further research.
