Peripancreatic fluid collections (PFCs) occur as a consequence of pancreatitis. Most PFCs resolve spontaneously, although 1%-2% persist and may require intervention. Conventional transluminal endoscopic drainage methods require the PFC to be bulging into the gastric wall; however, it is not uncommon for this to be absent. Imaging guidance for transluminal endoscopic PFC drainage allows the endoscopist to localize nonbulging pseudocysts that cannot be localized using endoscopy alone, to identify and avoid vascular structures between the cyst and the gastric lumen, and to reveal solid or necrotic components within the pseudocyst cavity. Although endoscopic ultrasound (EUS) has been used to meet this need, timely access to therapeutic EUS remains a limiting factor at many centres. We report our technique and experience performing transgastric endoscopic drainage of PFCs under computed tomography (CT) interventional radiology guidance.
胰周液体积聚（PFCs）是胰腺炎的后果。大多数 PFCs 会自行消退，尽管有 1%-2%的 PFCs 会持续存在并可能需要干预。传统的经腔内镜引流方法需要 PFC 向胃壁突出；然而，这种情况并不常见。经腔内镜 PFC 引流的影像学引导允许内镜医生定位不能仅通过内镜定位的非膨出假性囊肿，识别和避免囊肿和胃腔之间的血管结构，并显示假性囊肿腔内的实性或坏死性成分。虽然内镜超声（EUS）已被用于满足这一需求，但在许多中心，及时获得治疗性 EUS 仍然是一个限制因素。我们报告了在 CT 介入放射学引导下经胃内镜引流 PFCs 的技术和经验。
