Why the study?
Technical controversies exist regarding how endoscopic ultrasound (EUS) is performed, prompting a discussion of relevant available evidence from different points of view.
This review discusses technical controversies in performing endoscopic ultrasound, including equipment design, screen orientation, and radial versus longitudinal EUS.
Technical EUS controversies persist; leaves open optimal equipment and orientation standards pending prospective trials.
In "What should be known prior to performing EUS exams, Part I," the authors discussed the need for clinical information and whether other imaging modalities are required before embarking EUS examinations. Herewith, we present part II which addresses some (technical) controversies how EUS is performed and discuss from different points of view providing the relevant evidence as available. (1) Does equipment design influence the complication rate? (2) Should we have a standardized screen orientation? (3) Radial EUS versus longitudinal (linear) EUS. (4) Should we search for incidental findings using EUS?
