Overview

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.

Detailed description

This is a prospective feasibility study enrolling patients suffering from malignant biliary obstruction with failed or anticipated difficult ERCP. Consecutive patients satisfying the inclusion criteria would be recruited.

EUS-guided hepaticogastrostomy would be performed with the MG-biliary stent. The MG-biliary stent (Niti-S, Taewoong Medical, Gyeonggi-do, Korea) is a novel device designed for hepaticogastrostomy. The stent is a partially covered metal stent made by nitinol covered with silicone. One end of the stent is uncovered and designed for placement in the intrahepatic ducts. The other end has a self-folding design that creates a flange and prevents migration of the stent outside the stomach. The stent diameter is either 8 or 10mm and the length can be 6,8,10 or 12cm long.

Outcome parameters include safety, technical and clinical success
