Endoscopic ultrasonography-guided hepatogastrostomy (EUS-HGS) is an effective endoscopic modality for biliary drainage in the setting of concomitant gastric outlet obstruction [1] [2]. EUS-HGS however requires a dilated biliary system for technical success. This case report describes the first conversion of a percutaneous transhepatic biliary drain (PTBD) into an HGS in a non-dilated biliary system using EUS and interventional radiology techniques.
A 43-year-old man underwent hepatic resection for metastatic colon cancer with full surgical transection of the common bile duct ([Fig. 1 a]); PTBDs were placed. Definitive stable drainage was needed to start adjuvant chemotherapy. Therefore, a decision was taken to perform HGS.

Under EUS guidance, a non-dilated left intrahepatic bile duct was punctured with a 19-gauge needle but, given the small ductal caliber, wire passage was not possible. Two occlusive balloons were inserted via the PTBD, with one central and one peripheral to the puncture target ([Video 1]). Saline was infused between the balloons, dilating the isolated duct segment. This allowed passage of a 0.035-inch guidewire ([Fig. 1 b]); however, the wire traveled peripherally in the bile ducts, but was then successfully grasped with a snare and pulled out of the PTBD track. With control of both ends of the wire achieved, the HGS tract was easily dilated to 6 mm with a balloon inserted through the PTBD. During tract dilation, a 10 × 80-mm partially covered self-expandable metal stent was simultaneously loaded through the endoscope and was advanced through the HGS tract immediately following deflation of the balloon, thereby minimizing the time between dilation and stent insertion and reducing leakage of bile. The stent was deployed, resulting in excellent drainage ([Fig. 2]). The patient was discharged 4 days later after normalization of his bilirubin and removal of the PTBD.

We report the first successful conversion of a PTBD to an HGS using EUS and interventional radiology techniques in a non-dilated biliary system. This multidisciplinary approach may enhance the safety of HGS.
