 Method : A high frequency ultrasonic probe was passed through the endoscopic channel. Scanning was performed at the site of the endoscopic finding when the lesions were covered with water. T1a-EP cancer was diagnosed by endoscopic findings or magnified endoscopic findings better than by EUS. T1a-LPM was also diagnosed by magnified endoscopic findings, but EUS also gave precise diagnoses by delineating the muscuralis mucosea. The diagnoses of T1a-MM and T1b-SM1 by EUS were good. EUS especially gave better results in the differential diagnosis between T1b-SM2 and T1b-SM3.
