Comparison of clinical outcomes for single- and double-balloon enteroscope-assisted endoscopic retrograde cholangiopancreatography in patients with surgically altered anatomy

DBE and SBE showed comparable clinical success and safety profiles in ERCP for patients with SAA, although SBE required significantly longer procedure times. DBE could provide procedural efficiency benefits in cases where an extended procedure duration is expected. Furthermore, a preserved gastric anatomy and Roux-en-Y reconstruction were identified as independent risk factors for intubation failure.
