Core tip: Pancreatic fluid collections are a frequent complication of pancreatitis. Management includes correctly classifying these collections, initiating early enteral feeding, and draining symptomatic collections. Endoscopic ultrasound with stent placement is the technique of choice. Both metal and plastic stents are efficacious, though metal stents may offer an advantage. When necrosis is present within the collection, direct endoscopic necrosectomy may be required in addition to drainage. Lumen apposing metal stents allow for direct endoscopic necrosectomy through the stent and are preferred in these patients. When a pancreatic duct leak is suspected, endoscopic investigation and stenting is mandated.
