Case series demonstrates the use of a novel endoscopic ultrasound system for rectal lesions, suggesting effective outpatient management.
We present the first reported use of the EndoSound Vision System (EVS; EndoSound, Inc, Portland, OR) for rectal endoscopic ultrasound (EUS) in an ambulatory surgical center. Two patients with rectal subepithelial lesions underwent EVS-assisted EUS, followed by same day endoscopic mucosal resection. EVS provided high-resolution imaging while maintaining forward-viewing optics and full working channel access. Both procedures were completed safely and efficiently in the outpatient setting. These cases highlight the feasibility of using EVS for rectal EUS and same session intervention in a carefully selected outpatient setting. Further studies are needed to define its role alongside established diagnostic modalities.
