Objective To discuss the methods of diagnosis and treatment of cystic neoplasms of pancreas. Methods Demographic data, clinical manifestations, diagnostic exams, surgical procedures, pathological diagnosis, postoperative complications, and follow-up data of 29 patients with cystic neoplasms of pancreas were analyzed retrospectively. Results There were 8 （28%） serous cystic tumors （SCN）, 12 （41%） mucinous cystic tumors （MCN）, 3 （10%） intraductal papillary mucinous tumors （IPMN）, and 6 （21%） solid pseudopapillary tumors （SPT）. Eight cases of SCN, 7 cases of MCN, 1 case of IPMN, and 5 cases of SPT were all benign. The ages of the patients were from 15 to 78 years〔average, （49±17）years〕and all tumors were more common in female （76%, 22/29）. Twenty-three cases of 29 patients were performed operations, 22 cases were underwent surgical resection, and 1 case was performed exploration and biopsy. There was no surgery-related death. The rest 6 cases were not performed operation. Twenty-one cases followed-up for 6 months to 8 years 〔average, （2.7±2.3） years〕, 8 cases didn’t followed-up. Sixteen cases with surgical resection had no recurrence during follow-up period, 1 case performed exploration and biopsy died in 1 year after operation, and 4 cases of SCN without surgery didn’t deteriorate. Conclusions The most common cystic neoplasms of pancreas are mucinous and serous cysts. These tumors are more frequent in female. Although almost all serous cysts are benign, 42% of mucinous cysts are malignant. Misdiagnosis may delay appropriate treatment and increase mortality. The resection rate of pancreatic cystic tumor is high, and the prognosis is good after radical resection.
