"1. EUS-guided collection drainage (transgastric or transduodenal, performed by Lumen Apposing Metal Stents or double pigtail stents) and eventual endoscopic necrosectomy~2. EUS-guided biliary drainage (either of the extrahepatic or intrahepatic biliary tree / transduodenal or transgastric / either as access for subsequent rendez-vous or transpapillary stenting OR for transparietal stenting by metal or plastic stents).~3. EUS-guided gallbladder drainage via Lumen Apposing Metal Stents and eventual subsequent EUS-based cholecystolithotomy~4. EUS-guided gastro-jejunostomy through Lumen Apposing Metal Stents~5. EUS-directed ERCP in post-surgical anatomy (by gastro-gastrostomy or entero-enterostomy performed through Lumen Apposing Metal Stents)~6. EUS-guided pancreatic duct drainage"

Procedures involving a percutaneous access to a target region (fluid collection, gallbladder, biliary tree)

Surgical interventions to obtain a drainage (e.g. surgical necrosectomy, pancreatico-gastrostomy) or the bypass of a stricture (hepatico-jejunostomy or gastro-jejunostomy)

Other endoscopic procedures not involving EUS (enteral stenting, Enteroscopy-assisted ERCP)
