诊断技术的进步使得胰腺囊性肿瘤越来越多的被发现。此类疾病的诊治尚无很好的指南，各种类型之间的鉴别诊断仍比较困难。大多数胰腺囊性肿瘤属良性病变，仅需长期密切观察，务必根据病人个体情况采取合理治疗方案。虽然胰腺囊性肿瘤的手术死亡率很低，但并发症发生率较高。因此，必须严格把握手术指征。

Abstract    Pancreatic cystic neoplasms are detected at an increasing frequency due to an increased use and quality of abdominal imaging. There are well known differential diagnostic difficulties concerning these lesions. A conservative approach is feasible in patients with a clinical presentation suggestive of an asymptomatic serous cystadenoma. Surgical management, as well as follow-up, is discussed for each of the types of neoplastic lesions, including an uncharacterized cyst, based on patient data, symptoms, serum analysis, cyst fluid analysis and morphological features.
