Endoscopic Ultrasound-Guided Gastrojejunostomy and Rescue Technique to Simplify Endoscopic Retrograde Cholangiopancreatography in Surgically Altered Anatomy

Patients with surgically altered gastrointestinal anatomy are susceptible to gallstone disease and anastomotic strictures. In such cases, enteroscopy-assisted endoscopic retrograde cholangiopancreatography (ERCP) is traditionally used to access the biliary system through the Roux limb, with suboptimal success rates. With the advent of endoscopic ultrasound (EUS) and therapeutic tools including lumen-apposing metal stents, access to the biliary systemin surgically altered anatomy has been made simpler. We report a case of EUS-guided transenteric ERCP done in a patient with surgical(l)y altered anatomy and a rescue technique for difficult gastrojejunal anastomosis creation.
