EUS-Guided Drainage of Pancreatic Fluid Collections Using Fully Covered Self-Expandable Metal Stents.

KB Endoscopic treatment of pancreatic fluid collections involves internal drainage of the collection into the bowel lumen. Historically, in order to perform endoscopic drainage, 3 conditions have to be met. First, the fluid collection has to be reasonably mature (ie, it has to have a well-defined wall and be primarily liquid in content). Second, the wall of the fluid collection has to be adherent to the bowel lumen (unlike Figure 1, which shows a fluid collection with poor adherence). Third, the fluid collection has to be a reasonable size (generally >6 cm).
