 EUS(endoscopic ultrasonography)objectively evaluates the depth of invasion during the endoscopic diagnosis of colorectal cancer. It is particularly useful in determining the feasibility of endoscopic resection for the treatment of patients with early colorectal cancer. In a study involving 866 early colorectal cancer lesions diagnosed using EUS, the rate of correct diagnosis with respect to the selection of the most appropriate treatment method was satisfactory(90%). In addition, EUS demonstrated good results for the diagnosis of tumors associated with ulcerative colitis. EUS is also characterized by limitations such as frequent difficulties in imaging lesions. However, the extension of the range of indications for this method to include the endoscopic treatment of pT1b colorectal cancer is being discussed, in association with the increased use of ESD(endoscopic submucosal dissection)for the treatment of colorectal tumors. The clinical significance of ESD is currently being reevaluated. Realizing the complete potential of EUS for the management of colorectal cancer may require the development of improved instruments for performing EUS for colorectal cancer.
