title: The efficacy of double-balloon enteroscopy for intrahepatic bile duct stones after Roux-en-Y hepaticojejunostomy for choledochal cysts.
abstract: BACKGROUND
  Intrahepatic bile duct (IHBD) stones are one of the most complicated morbidities that occur after Roux-en-Y hepaticojejunostomy (RYH); however, the optimal therapeutic approach is controversial.
  
  
  METHODS
  Double-balloon enteroscopy (DBE) has been widely and frequently performed even in pediatric patients. We herein report the successful management of IHBD stones by biliary lithotripsy using DBE after RYH for a choledochal cyst (CC). DBE has made it possible to perform endoscopic therapeutic intervention, including balloon dilatation of an anastomotic stricture and removal of IHBD stones, without any major complications.
  
  
  CONCLUSIONS
  DBE is a less invasive and safe treatment method for IHBD stones in pediatric patients, which is capable of reaching the bilioenteric anastomosis after RYH for CC.
