Core Tip	Double-balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (DBE-ERCP) is a safe and effective approach for the management of pancreatobiliary diseases in patients with surgically altered anatomy. This updated systematic review and meta-analysis of 40 studies including 2689 patients demonstrates high enteroscopic (89%), diagnostic (90%), and procedural (92%) success rates, with a low overall adverse event rate (5.7%). Subgroup analysis indicates that short-type double-balloon enteroscopy (DBE) outperforms long-type DBE in procedural success and papilla access. These findings highlight the clinical utility of DBE-ERCP and suggest that short-type DBE may offer greater advantages, though further randomized controlled trials are warranted.
