Abstract    Objective    To investigate the diagnosis and treatment of cystic neoplasms of the pancreas. Methods Retrospective analysis was made on the clinical data of 212 cases of pancreatic cystic neoplasms from January 2000 to December 2010 in Zhongshan Hospital. Results    There were 101 cases of IPMNs(48%), 49 cases of MCNs(23%) and 62 cases of SCNs(29%) . No special clinical manifestation was observed. 90%, 93% and 94% accuracy can be achieved by ultrasound, CT and MRI on the diagnosis of cystic tumor respectively. The postoperative incidence of pancreatic fistula is 34.3%. All the cases of SCN, non-invasive MCN and IPMN survived five years or longer, while the five-year survival rate of invasive MCNs and IPMNs is just 31% and 35% respectively. Conclusion    Both CT and MRI are accurate on  preoperative diagnosis of pancreatic cystic tumors. Priority should be given to function-saving-operation for SCN, non-invasive MCN and IPMN cases, while the invasive PNCs should receive standard pancreatectomy plus regional lymph nodes dissection. The overall prognosis of pancreatic cystic tumor is satisfactory.
