This report describes antegrade electronic hydraulic lithotripsy (Lithotron EL 27; Walz Elektronik, Rohrdorf, Germany) using a digital peroral cholangioscope (SpyGlass DS System; Boston Scientific, Marlborough, Massachusetts, USA) [1] [2] through an endoscopic ultrasound (EUS)-guided hepaticojejunostomy route for common bile duct (CBD) stones ([Video 1]).

Video 1 Antegrade electronic hydraulic lithotripsy using a digital peroral cholangioscope through an endoscopic ultrasound-guided hepaticojejunostomy fistula. This novel method could become a rescue procedure when the conventional transpapillary approach is unsuccessful.


Quality:

A 77-year-old man, who underwent total gastrectomy with a Roux-en-Y procedure for gastric cancer, presented with cholangitis caused by CBD stones. Endoscopic transpapillary drainage was attempted, but the scope could not be inserted into the ampulla; therefore, EUS-guided hepaticojejunostomy was performed.

From the Roux-en-Y jejunum, the dilated intrahepatic bile duct was punctured with a 19-gauge needle under EUS. After guidewire insertion toward the distal bile duct, the puncture site was dilated using a balloon dilator (diameter 4 mm, REN; Kaneka Medix, Osaka, Japan) ([Fig. 1]). A covered metal stent (diameter 8 mm, length 8 cm, Niti-S; Taewoong Medical, Gyeonggi-do, South Korea) was inserted between the intrahepatic bile duct and the Roux-en-Y jejunum ([Fig. 2]). The following day, the patient’s cholangitis was markedly improved, and he was discharged 3 days after surgery.

The patient was re-admitted to our hospital 4 weeks later to continue treatment for CBD stones. The cholangioscope was inserted over the guidewire through the metal stent ([Fig. 3]), and the CBD stones were revealed by cholangioscopy ([Fig. 4 a]). The stones were crushed by electronic hydraulic lithotripsy ([Fig. 4 b]). Subsequently, the metal stent was removed and a balloon dilator was inserted into the fistula toward the ampulla and dilated up to 12 mm ([Fig. 5 a]). The CBD stones were pushed out into the digestive tract in an antegrade fashion using a balloon catheter ([Fig. 5 b]). Finally, a single-pigtail plastic stent (7 Fr, 20 cm length) [3] was deployed between the CBD and the Roux-en-Y jejunum ([Fig. 6]). The patient resumed eating 4 days after surgery with no adverse effects, and was discharged 7 days after surgery.
