Abstract    Intraductal papillary mucinous neoplasm（IPMN）is divided into three categories: main duct, mix and branch duct IPMN. For main and mixed IPMN, and branch duct with symptoms, resection is suggested. For malignant IPMN, regular pancreatectomy should be performed, while for benign and borderline IPMN, function preserving pancreatectomy is preferred. For patients who temporarily need not resection, regular follow-up should be given up to 36 months. Comprehensive judgments are need for decision making of treatment strategy of IPMN, such as life expectancy of patients, physical condition, willingness to treatment, compliance and accessibility to follow-up, and finally reach to individualized treatment plan.
