Core Tip
Core Tip: In a recent study, endoscopic ultrasound-guided biliary drainage reportedly demonstrated similar safety between elderly patients and all other patients. However, the appropriate stent for placement in elderly patients is unknown. This work reports that plastic stents are sufficient for patients with benign biliary diseases because they result in good outcomes and allow easier reintervention, whereas metallic stents are appropriate for older patients with malignancies because they offer better outcomes and a reduced physical burden of endoscopic reintervention.
