Pancreatic fluid collections (PFCs) are common complications of acute pancreatitis. Asymptomatic collections do not require drainage while symptomatic or infected collections should be drained. Drainage can be performed surgically, percutaneously, or endoscopically. Recent studies have shown that endoscopic drainage of PFCs is equivalent or superior to surgical or percutaneous drainage, with less complications. Advances in tools and technology coupled with increasing expertise in management of PFCs has resulted in minimally invasive endoscopic drainage, by endosonographic guidance, being the preferred approach. New larger diameter lumen apposing metal stents (LAMS) have simplified the process of drainage. LAMS have also made performing direct endoscopic necrosectomy for walled-off necrosis (WON) easier. Technique, duration, frequency, and tools used for direct endoscopic necrosectomy are variable. Performing PFC drainage requires adequate and fundamental knowledge of diagnostic and basic therapeutic EUS.
胰液积聚（PFCs）是急性胰腺炎的常见并发症。无症状的积聚无需引流，而有症状或感染的积聚则应进行引流。引流可通过手术、经皮或内镜方式进行。最近的研究表明，PFCs的内镜引流与手术或经皮引流效果相当或更优，且并发症更少。工具和技术的进步，以及PFCs管理专业知识的不断增加，使得在超声内镜引导下进行微创内镜引流成为首选方法。新型大口径管腔对合金属支架（LAMS）简化了引流过程。LAMS也使对包裹性坏死（WON）进行直接内镜坏死组织清除术变得更容易。用于直接内镜坏死组织清除术的技术、持续时间、频率和工具各不相同。进行PFC引流需要具备诊断性和基本治疗性超声内镜的充分基础知识。
