EUS-guided Hepatico-gastrostomy Using a Novel Lumen Apposing Metal Stent

EUS-guided biliary drainage is gaining popularity as a means of achieving endoscopic drainage in patients with failed endoscopic retrograde cholangiopancreatography (ERCP) 1. EUS-guided hepaticogastrostomy (HGS) is a type of EUS-guided biliary drainage and the procedure is employed when the ERCP fails due to a malignant bile duct obstruction but the papilla is inaccessible or if the first of the duodenum is infiltrated by tumor. Recently, a novel dedicated HGS (Niti-S, Taewoong Medical, Gyeonggi-do, Korea) has become available, the stent has a novel design to that prevents the stent from migration, further improving the safety. The aim of the current study is to evaluate the feasibility and outcomes of the novel lumen apposing stent for EUS-guided HGS. The hypothesis is that the device is safe and effective.
