Core Tip	This randomized meta-analysis included six trials and 739 participants. Primary transmural ultrasound-guided and retrograde biliary drainage achieved comparable clinical success rates. Ultrasound-guided drainage reduced post-procedural pancreatitis from 6.6% to 0.5%, with concordant rare-event sensitivity analyses. Technical success varies across devices and trials, whereas its effects on other adverse events and repeat interventions remain uncertain. Evidence supports ultrasound-guided drainage as an alternative for selected patients in expert centers, and not as a universal replacement for retrograde drainage.
