EUS-PDD demonstrated higher technical and clinical success than eERP-PDD for PJS, with comparable safety after adjustment. An MPD diameter ≥ 5 mm was associated with eERP-PDD failure. An MPD-based algorithm is proposed: eERP-PDD for MPD < 5 mm with EUS-PDD as salvage, and EUS-PDD for MPD ≥ 5 mm. This algorithm is hypothesis-generating and requires prospective validation.
