Novel technique using a non-tip and short-wire papillotome for biliary cannulation of intradiverticular papilla in patients with Roux-en-Y anastomosis

Abstract

Balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP) has enabled the endoscopic treatment of pancreatobiliary disease in patients with a surgically altered gastrointestinal anatomy.^1-3 However, even though the endoscope can reach the papilla, successful cannulation of the common bile duct may be difficult in the papilla located within a diverticulum because of an insufficient distance from the papilla in the tangential direction. Therefore endoscopic ultrasound-guided biliary drainages have been reported as useful and safety methods.^4-5 Herein, we report BE-ERCP using a papillotome for cannulation of the intradiverticular papilla in R-Y anastomosis patients with choledocholithiasis.
