An innovative technique using a percutaneously placed guidewire allows for higher success rate for ERCP compared to balloon enteroscopy assistance in Roux-en-Y gastric bypass anatomy

Endoscopic retrograde cholangiopancreatography (ERCP) is technically challenging in Roux-en-Y gastric bypass (RYGB). Current approaches either have high failure rate, are resource intensive, or invasive. To describe successful adoption of an old technique for performance of ERCP in patients with RYGB anatomy employing enteroscopy with the assistance of a percutaneously placed guidewire, which facilitates both reaching and cannulating the major...
