Thin-probe endoscopic ultrasonography for surgical resection of early colorectal neoplasms: A pilot study

Abstract

Purpose: To retrospectively analyze the results of our therapeutic recommendations for EMR and surgical operation using thin-probe EUS for patients with early colorectal neoplasms. Methods:We retrospectively analyzed the therapeutic recommendation for using EUS and the results in 63 lesions of 63 patients. When the depth of the change for the third layer (submucosal layer) was 1 millimeter or more, we recommended surgical operation(EUS operation-recommended group). Results: Surgical operation was suitable for all of lesions in the EUS-operation-recommended group (23 lesions of 23 patients). Conclusion:We think that a change of 1 millimeter or more in the third layer (corresponding to the submucosal layer) in EUS for colorectal neoplasms may be a useful finding for surgical decision making.
