  • 摘要: 随着医学影像技术的发展,胰腺囊性肿瘤(PCN)的检出率逐年增加。PCN包含多种类型,不同类型的PCN生物学特性和恶变风险均有显著差异。由于目前国内缺乏相应指南或共识,导致PCN临床诊断标准不一、缺乏规范的问题较为突出。本指南结合国内外研究进展,基于PCN临床症状、影像或内镜诊断以及随访策略等问题,共提出17条推荐意见,旨在规范我国PCN诊断决策和监测随访流程,促进多学科整合,进一步提升该病的规范化诊断与治疗水平。

    临床问题 推荐意见
    PCN会引起临床症状吗? 大多数PCN无症状,需谨慎地将症状归结于PCN所致。
    何种影像学检查可用于诊断PCN? MRI检查是诊断PCN的首选方法。
    EUS是否应用于所有PCN的患者? 影像学如提示存在病灶最大径>3 cm、壁结节>5 mm、囊壁增厚或强化、主胰管扩张>5 mm、胰管截断伴远侧胰腺萎缩、淋巴结肿大、CA19-9升高、病灶增长速度≥5 mm/2年等征象,建议行EUS进一步评估。EUS联合其他影像学检查可提高PCN的诊断准确度。
    EUS-FNA/FNB的适应证是什么? 对于影像学检查不能确定性质的PCN或EUS-FNA/FNB可能改变治疗策略时,建议行EUS-FNA/FNB。
    应选择哪些囊液检测方法对胰腺囊性病灶进行鉴别诊断? 囊液分析如拉丝试验、细胞学、淀粉酶、CEA、葡萄糖检测及KRAS/GNAS基因突变分析可用于鉴别PCN类型。
    EUS-TTNB相比EUS-FNA是否能够提高PCN的诊断效能? EUS-TTNB相比EUS-FNA能显著提高PCN的诊断效能,同时EUS-TTNB不良事件发生率较低。
    应在何种情况下考虑将nCLE应用于PCN患者? nCLE应使用于拟行手术治疗而无法排除SCN的PCN患者。
    CE-EUS是否可用于评估PCN的性质? CE-EUS可显示病变血供,建议使用CE-EUS进一步评估壁结节,亦有助于评估囊内血管和分隔。CE-EUS上出现壁结节、实性肿块或分隔的过度强化,需警惕病变恶变可能,应考虑对病变处进行EUS-FNA。
    MD-IPMN或MT-IPMN是否需行胰管镜检查? 合并高危征象或临床难以鉴别的MD-IPMN或MT-IPMN推荐行胰管镜检查。
    何类PCN患者应列为随访对象? 诊断考虑为MCN或IPMN的无症状性PCN且具备手术条件的患者应列为随访对象。恶变风险极低的SCN患者建议根据症状进行随访。
    何种检查方法为PCN随访人群的最佳选择? 推荐MRI联合MRCP作为IPMN或MCN的随访检查方法。EUS或CT可作为存在MRI禁忌患者的随访检查方法。
    PCN患者的最佳随访周期是多久? 推荐无高危征象的IPMN或MCN可根据病灶大小制定监测随访策略。含高危征象的IPMN或MCN经多学科会诊(multi-disciplinary treatment,MDT)后未行手术者建议间隔6月进行MRI随访。
    注:PCN为胰腺囊性肿瘤;MRI为核磁共振;EUS为超声内镜;EUS-FNA/FNB为超声内镜引导下细针穿刺活检;EUS-TTNB为超声内镜引导经穿刺针活检钳活检术;nCLE为细针型共聚焦激光显微内镜;CE-EUS为对比增强EUS;MD-IPMN为主胰管型胰腺导管内乳头状黏液性肿瘤;MT-IPMN为混合型胰腺导管内乳头状黏液性肿瘤;MCN为黏液性囊腺瘤;SCN为浆液性囊腺瘤;MRCP为磁共振胰胆管造影;CT为电子计算机断层扫描。
