Endoscopic ultrasound

Endoscopic ultrasound (EUS) continues to present a rich source of innovation, allowing it to evolve from a diagnostic procedure to a therapeutic modality. This was obvious from the numerous high-quality presentations at the 2014 Digestive Disease Week (DDW) held in Chicago, Illinois. This review discusses several of the presented abstracts of innovations in the field of EUS.
