A case of severe hepatolithiasis after hepaticojejunostomy with Roux-en-Y reconstruction treated by endoscopic ultrasound-guided transhepatic antegrade stone removal

Balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (ERCP) is useful for the treatment of bile duct stones in patients with surgically altered anatomy [1] [2] [3]; however, the procedure cannot always successfully remove stones when the anastomotic site or papilla of Vater cannot be reached. Recently, endoscopic ultrasound (EUS)-guided antegrade intervention has been developed for benign biliary diseases, including hepatolithiasis in patients with altered anatomy [4] [5]. We report a case of EUS-guided transhepatic antegrade stone removal (EUS-TASR) in a patient with altered anatomy ([Video 1]).

Video 1 Endoscopic ultrasound-guided transhepatic antegrade stone removal was useful for severe hepatolithiasis after hepaticojejunostomy with Roux-en-Y reconstruction.

The 59-year-old man underwent hepaticojejunostomy with Roux-en-Y reconstruction for hepatolithiasis several years previously. He was referred to our hospital for treatment of severe hepatolithiasis. Abdominal computed tomography showed huge impacted stones in the hilum and a dilated left intrahepatic bile duct ([Fig. 1 a] ).

We chose to perform EUS-TASR because accessing the anastomotic site by balloon-assisted ERCP was judged to be difficult owing to the long afferent loop and because multiple sessions would be required for stone removal.

We first performed EUS-guided hepaticogastrostomy (EUS-HGS). The dilated left intrahepatic bile duct was punctured using a 19-gauge fine-needle aspiration needle from the residual stomach side. Cholangiography showed multiple impacted stones from the hilum to the bilateral intrahepatic bile ducts. A 0.025-inch guidewire was inserted into the intrahepatic bile duct and the needle tract was dilated using an ultra-tapered mechanical dilator. A fully covered metal stent was then placed over the guidewire ([Fig. 2]).

EUS-TASR was performed 1 month later. After dilation of the anastomotic stricture using a balloon catheter, a cholangioscope was inserted into the intrahepatic bile duct through the metal stent. Bile duct stones were crushed using electrohydraulic lithotripsy under direct visualization ([Fig. 3]). Subsequently, stone fragments were removed using a basket catheter and balloon catheter through the anastomotic route and HGS route ([Fig. 4]). Finally, the huge hepatic bile duct stone was completely removed ([Fig. 1 b]).
