Technological advances have greatly expanded the diagnostic and therapeutic capabilities of endoscopic ultrasound (EUS). The integration of cutting-edge imaging techniques, including tissue harmonic echo, contrast-enhanced harmonic EUS, elastography, and needle-based confocal laser endomicroscopy, have significantly enhanced lesion characterization and diagnostic accuracy. Additionally, developments in stent design and the introduction of new accessories have broadened the therapeutic applications of EUS. Ongoing innovations in clinical practice have transformed procedures such as drainage, tumor ablation, EUS-directed transgastric endoscopic retrograde cholangiopancreatography (ERCP), the placement of fiducial markers, advancements in endohepatology, lesion characterization, and treatment. These developments continue to expand the role of EUS in delivering precise and effective therapeutic interventions.
