Pancreatic Fluid Collection Drainage by Endoscopic Ultrasound: New Perspectives

Since the introduction of endoscopic ultrasonography (EUS), many centers have utilized this imaging modality for transmural pancreatic fluid collection (PFC) drainage. The expanded use of EUS has resulted in increased safety and efficacy of endoscopic PFC drainage. The major procedural steps include EUS-guided transgastric or transduodenal fistula creation into the PFC, and stent placement or nasocystic drain deployment to decompress the collection. In this and other applications, EUS has become a major therapeutic advancement in the field of endoscopy and has figured in myriad diagnostic applications. Recent research indicates a number of situations in which EUS-guided PFC drainage is appropriate. These include unusual location of the collection, small window of entry, non-bulging collections, coagulopathy, intervening varices, or failed conventional transmural drainage. In this study, we discuss the EUS-guided technique and review current literatures.
