Oblique‐viewing curved linear‐array echoendoscopes are widely used for interventional endoscopic ultrasound (EUS), not only for diagnostic but also for therapeutic procedures. Recently, development of a forward‐viewing curved linear‐array echoendoscope (FV‐ES) has been made. Several reports describe the usefulness of this new equipment for therapeutic interventional EUS, especially for pseudocyst drainage. A salient advantage of the FV‐ES is that it enables the axial application of force during needle insertion and stenting. Furthermore, by attaching a cap device to the tip, the endoscope's capability can be expanded. Although the FV‐ES has a narrower scanning range (90 deg) than that afforded by the oblique‐viewing curved linear‐array echoendoscope (180 deg), this characteristic reportedly does not hinder the performance of interventional EUS. The FV‐ES might contribute to the advancement of interventional EUS.
