Successful biliary stent placement using balloon enteroscopy-assisted ERCP in a patient with rare surgically altered anatomy who underwent Roux-en-Y reconstruction twice

Balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography can be the first choice for patients with such complex surgically altered anatomy, especially in those without biliary dilation.
