Endoscopic Ultrasound (EUS) Functionality for a Standard Upper Endoscope: Initial US Experience

A novel EUS system (EndoSound EVS) that converts a standard endoscope was evaluated in a retrospective study of 61 patients. The system demonstrated high clinical effectiveness, with a 90% procedural success rate and 100% sampling success for interventions involving the esophagus, stomach, and duodenal bulb. Fourteen patients required fine needle aspiration or biopsy, which were all successfully completed without any adverse events. The study suggests this technology has the potential to improve patient access to EUS evaluations by reducing equipment costs and procedural complexity.
