Pancreatic Fluid Collection Drainage by Endoscopic Ultrasound: New Perspective

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 PFCdrainage. The major procedural steps include EUS-guided transgastric or transduodenal fistula creation into the PFC, and stentplacement or nasocystic drain deployment to decompress the collection. In this and other applications, EUS has become a majortherapeutic advancement in the field of endoscopy and has figured in myriad diagnostic applications. Recent research indicates anumber of situations in which EUS-guided PFC drainage is appropriate. These include unusual location of the collection, smallwindow of entry, non-bulging collections, coagulopathy, intervening varices, or failed conventional transmural drainage. In thisstudy, we discuss the EUS-guided technique and review current literatures.
