胰腺导管内乳头状黏液性肿瘤（intraductal papillary mucinous neoplasm，IPMN）分主胰管型、混合型和分支胰管型。主胰管型、混合型和有症状的分支胰管型IPMN建议行手术切除，对恶性IPMN，需行规则性胰腺切除。对良性和交界性IPMN，可行功能保留性胰腺手术。对暂时不行手术切除的IPMN病人，应定期随访。IPMN的治疗决策需综合考虑各方面因素，包括病人的预期寿命、身体状况、治疗意愿、依从性、随访的条件等加以综合评估，最后形成个体化的治疗方案。

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.
