A multicenter retrospective cohort analyzed patients aged 70 years or older who underwent successful EUS-BD, comparing metallic stents and plastic stents.

In a recent study, EUS-BD reportedly demonstrated similar safety between elderly patients and all other patients. However, the appropriate stent for placement in elderly patients is unknown.  \nAIM  \nTo clarify whether a metallic stent (MS) or a plastic stent (PS) is suitable when performing EUS-BD in elderly patients.  \n WJGE  [https://www.wjgnet.com](https://www.wjgnet.com) 1 December 16, 2025  Volume 17  Issue 12   \nSugimoto M et al.

The data of patients aged 70 years or older who underwent successful EUS-BD were analyzed, and the longterm outcomes of patients treated with an MS (MS group) and those treated with a PS (PS group) were compared.  \nRESULTS  \nNinety-four patients underwent successful EUS-BD, of whom 64 were aged 70 years or older. The PS group included 51 patients, and the MS group included 13 patients. The time to recurrent biliary obstruction (TRBO) was not significantly different between the PS group and the MS group (6-month recurrent biliary obstruction rate 50.8% vs 26.8%, P = 0.18) .
