EUS-guided transhepatic cholangiography: report of 6 cases
Background:
This report describes a novel application of EUS-guided cholangiography in which a transhepatic approach was used to alleviate perihilar and distal biliary obstructions when this could not be accomplished at ERCP.
Methods:
EUS-guided transhepatic cholangiography was used to alleviate symptoms of biliary obstruction in 6 patients. In 4 cases, after transgastric puncture of an intrahepatic branch of the obstructed bile duct with a 19- or a 22-gauge EUS needle, a guidewire was advanced antegrade across both the biliary stricture and the papilla. Subsequently, a rendezvous procedure was performed, allowing ERCP and stent placement.
Observations:
EUS-guided transhepatic cholangiography was performed in 6 patients, with successful rendezvous ERCP and stent placement in 4, and transduodenal stent placement in another patient. Stent placement was unsuccessful in one patient, because of the inability to advance a guidewire into the common hepatic duct. There was no immediate complication of the procedures.
Conclusions:
EUS-guided transhepatic cholangiography can be used to access and to drain bile ducts that are obstructed by proximal, as well as distal lesions when ERCP is unsuccessful.
