摘要

胰周液体积聚（PFCs）是急性胰腺炎常见并发症，其精准管理对预后至关重要。超声内镜（EUS）凭借高分辨率成像与实时介入能力，已成为PFCs诊疗的核心工具。本文系统综述EUS在PFCs分类诊断（依据2012年修订版亚特兰大标准）、技术优势（如微创引流、血管规避能力）及治疗策略中的进展。研究显示，EUS在区分假性囊肿（PPC）与包裹性坏死（WON）方面准确性显著优于CT（89.6% vs. 13.7%），且EUS引导引流技术成功率高达93.9%~97.4%，住院时间短、并发症率低。新型支架（如LAMS）的运用进一步优化了疗效。尽管面临设备成本高、操作依赖经验等挑战，EUS通过多技术融合（如EUS-MRI）及规范化培训持续提升临床价值，未来有望成为PFCs个体化诊疗的普惠性方案。
