title: Temporary endosonography-guided biliary drainage for transgastrointestinal deployment of a self-expandable metallic stent.
abstract: Endosonography-guided biliary drainage (ESBD) is now gaining acceptance as a useful alternative for the management of obstructive jaundice.(1) At present, ESBD is used mainly to establish an anastomosis between the biliary tree and the duodenum, stomach, jejunum, or esophagus by placing a stent so as to bridge the bile duct and alimentary tract. We herein report a new application of ESBD, that is, its temporary use for gaining access to the bile duct in order to deploy a self-expandable metallic stent (SEMS) via the transhepatic route. In a patient with pylorus stenosis due to advanced gastric cancer with extrahepatic bile duct obstruction caused by nodal metastasis, a plastic stent was placed temporarily by ESBD to bridge the esophagus and the left hepatic duct. Ten days later, the stent was retrieved, leaving a guidewire in the bile duct, and a delivery unit of a SEMS was introduced into the bile duct over the guidewire via the sinus tract. The SEMS was then successfully deployed through the stenosis. No stent was left in the sinus tract. This procedure yields a mature fistula through which a delivery unit can be safely introduced into the bile duct followed by uneventful deployment of a SEMS.
