Abstract    Pancreatic cystic neoplasm(PCN) are a rare subset of pancreatic tumors , mostly benign, but some are malignant or with malignant transformation and metastatic potential. Preoperative judgement to benign or malignant types turns out to be key factors in determining treatments.About the operation timing and operation methods to PCN,there has been controversy at home and abroad, especially for branch duct type intraductal papillary mucinous neoplasm(BD-IPMN). Due to the low incidence of PCN, currently there is still no international evidence based guidelines. For serous cystic neoplasm(SCN),the vast majority of them are benign,operation should be very cautious;for mucinous cystic neoplasm(MCN)，main duct type intraductal papillary mucinous neoplasm(MD-IPMN) and solid pseudopapillary neoplasm(SPT),most of them are benign,but are believed to have malignant transformation potential or have been malignant,should be resected as soon as possible;for BD-IPMN, it is still controversy to it’s malignant transformation potential and is hard to judge the cut-off point,so operation and timing is the hot point to discuss.As the PCN’s spectrum ranges from benign,PanIN,carcinoma in situ to malignancy,the operational methods range from enuleation to pancreaticoduodenectomy.
