Tip-Balloon Anchored Retroflex (T-BAR) Method for Double Balloon Endoscopy-Assisted ERCP in Roux-en-Y Anatomy.

With accompanying video, Fukuba and colleagues described the Tip-Balloon Anchored Retroflex (T-BAR) technique for double-balloon enteroscopy-assisted ERCP in Roux-en-Y anatomy with an intact papilla. By using the tip balloon as an anchor, the method stabilizes retroflex positioning, prevents scope slippage, improves biliary axis alignment, and facilitates selective biliary cannulation.
