Sponsor's own description
Background: Transpapillary EUS-BD (rendezvous/antegrade) is gaining acceptance in BBO. The potential of transmural EUS-BD (hepaticogastrostomy/choledochoduodenostomy) in complex BBO warrants study. Aims: To assess feasibility and efficacy of TEA using transmural covered self-expandable metal-stents (cSEMS) to provide interval biliary drainage and create TAF for biliary endotherapy under cholangioscopy or fluoroscopy in BBO not amenable to ERCP.
