Abstract    The incidence of pancreatic cystic neoplasms is low, most of these tumors present benign prognosis. Pancreatic mucinous adenocarcinoma and intraductal papillary mucinous cystadenocarcinoma often present recurrence, the former presents high degree of malignancy and the latter often progresses slowly. It is critical to regular imaging follow-up for detection of the recurrence and assessment the resectability. Reoperation is the only way to radical re-resection of the recurrence lesions. However, the success of radical re-resection depends on pathological type of primary tumor and the duration of tumor recurrence. There are very low chance to re-resect the recurrence of pancreatic mucinous adenocarcinoma. On the contrary, it is more likely to re-resect the recurrence of pancreatic intraductal papillary mucinous carcinoma.
