Aims: High-frequency miniprobes (HFPs) and conventional radial endoscopic ultrasound (crEUS) are considered to be valuable tools in the staging of early esophageal carcinomas. However, there is some controversy on whether HFPs are superior in the T staging of early esophageal neoplasias or whether the same level of accuracy can be achieved by the sole use of crEUS. Objective: To compare the accuracy of T staging and N staging with HFP and crEUS. Design: Prospective randomized trial (ratio 1:1) with a cross-over design. Methods: Patients (Pts) referred for endoscopic treatment for early Barrett's carcinoma (BC) w…
