Single-balloon enteroscopy for treating Roux-en-Y choledochojejunostomy stenosis after liver transplantation: a case report.

Endoscopic treatment of biliary tract complications after Roux-en-Y surgery is still a challenge. With balloon enteroscopy, we can reach previously inaccessible areas changing the management of biliopancreatic diseases in patients with surgically altered anatomy. We report a case of single-balloon enteroscopy plus endoscopic retrograde cholangiopancreatography for the treatment of a pinpoint stricture in a hepaticojejunal anastomosis after liver transplantation.
