982 SINGLE-SCOPE TRANSGASTRIC ANTEGRADE CHOLANGIOSCOPY (STAC) AND INTRADUCTAL POLYPECTOMY VIA EUS-GUIDED HEPATICOGASTROSTOMY (HGS) WITH A LUMEN-APPOSING-METAL STENT (LAMS)

Tissue diagnosis and biliary drainage are standard steps in the palliative management of pancreaticobiliary malignancies. These steps are typically undertaken by EUS-FNA and ERCP, respectively. We present a case in which EUS-FNA failed to diagnose polypoid cholangiocarcinoma and ERCP failed to drain the upstream duct. EUS-guided hepaticogastrostomy (HGS) was performed with a lumen-apposing metal stent (LAMS). HGS provided biliary drainage and access for single-scope transgastric antegrade cholangioscopy (STAC).
