The aim of the study was to determine the treatment for Tis and T1 colorectal cancer and the depth of cancer invasion which was examined preoperatively by intraductal ultrasonography (IDUS) using a 20 MHz high frequency thin sonoprobe. IDUS was performed on 62 patients with Tis and T1 colorectal cancer using 20 MHz radial images. The tumors imaged by IDUS were classified into 3 groups according to the degree of lesions in the 5 layers of the large intestinal wall: Tis showing no changes in the third layer, T1 with slight invasion in which the ruptured region in the third layer occupied less than 50% of the tumor diameter, and T1 with massive invasion in which the ruptured region in the third layer occupied more than 50% of the tumor diameter. The correct preoperative diagnosis of the depth of the lesions was obtained in 21 of the 23 patients with Tis (91.3%), in 18 of the 21 patients with T1 with slight invasion (85.7%), and in 8 of the 11 patients with T1 with massive invasion (72.7%). In conclusion, IDUS can be used for endoscopic examination of the large intestinal cancer to judge whether local treatment or not.
