The Usefulness Of Condom Method Eus For Esophageal Mass Evaluation

23 Background: The endoscopic ultrasonography (EUS) is positioned as the method of choice to evaluate the origin and depth of invasion for the esophageal mass. To overcome the disadvantages as aspiration resulting from water filling EUS and balloon rupture resulting from balloon EUS, we used condom method EUS for esophageal mass evaluation. Methods: We investigated retrospectively twenty six patients examined condom method EUS using high frequency ultrasound probes after diagnosed esophageal mass lesion including submucosal tumor by standard endoscopy between January 2007 and April 2015 at Seoul Paik Hospital, Seoul, Korea. We checked the originating layer, invasion depth and echogenicity of the mass and events complicated by procedure. Results: The condom method EUS provided high quality images without aeration and well-defined five layers of esophagus through 360 degrees. In all segments of esophagus; upper (n = 5), middle (n = 10), lower esophagus(n = 11), showed high resolution images without differen...
