Pancreatic Pseudocyst Drainage Using Lumen-Apposing Metal Stents.

MK Currently, the most common approach is with endoscopic ultrasound (EUS) guidance. Using EUS with a large working channel, the endoscopist can puncture and then drain the fluid collection after checking local vasculature with Doppler ultrasound. The drainage will depend on the type of fluid collection. For example, if the patient has a simple pseudocyst, the endoscopist could place a single 10-French plastic stent. However, if the patient has an infected fluid collection, typically the endoscopist would place many plastic stents or consider lumen-apposing metal stents (LAMS; Figure 1).
