Transluminal bile duct stone removal via EUS-guided anastomosis has been reported as an alternative treatment technique for patients with failed stone removal under endoscopic retrograde cholangiopancreatography guidance and has a lower likelihood of acute pancreatitis compared with antegrade transpapillary stone removal.,,, Although this procedure has clinical benefits, device insertion into the common bile duct is sometimes difficult because of anatomical variations in the curvature of the intrahepatic or common bile duct and can be complicated by stone migration into a bile duct branch if a balloon catheter is used during the procedure. A novel spiral basket catheter with a snake-shaped sheath (RASEN, KANEKA Medical, Osaka, Japan) designed to overcome these issues has recently become available in Japan [Figure 1]a. The specialized shapes of the basket catheter and sheath enable smooth insertion of the device and reliable stone extraction [Video 1 [Additional file 1]]. We herein describe a case of successful transluminal stone removal using this novel basket catheter.

An 82-year-old female who had undergone total gastrectomy was admitted to our hospital with acute cholangitis due to a stone in the common bile duct. EUS-guided hepaticojejunostomy (EUS-HJS) was performed initially, and stone removal was attempted 1 week later using the following technique. A guidewire was inserted into the common bile duct via the EUS-HJS route and contrast medium was injected [Figure 1]b. The basket catheter was then inserted. The snake-shaped sheath enabled the device to be advanced smoothly into the lower common bile duct [Figure 2]a. After stone extraction [Figure 2]b, we successfully removed the device transluminally without any adverse events [Figure 2]c. This novel basket catheter opens a new indication for difficult bile duct stone removal, by the transluminal route as well as the transpapillary route.
