  • Look Inside

 To study the ultrasonography for the cancer of the colon, three methods, namely, 1) the conventional ultrasonography from outside of the abdominal wall, 2) the tepid water-filling ultrasonography from outside of the abdominal wall and 3) the endoscopic ultrasonography were evaluated. The conventional ultrasonography had poor sensitivity in detecting the cancer of the colon, and was only able to find one which existed in the upper part of the abdomen forming the mass. By tepid water-filling ultrasonography, it could project, in the minimum, polyps 2 mm in size which existed in the region where it was possible to fill the tepid water, but it was difficult to differentiate the polypoid cancer. However, the structure of the colonic layer and its destruction in advanced cancer was seen. By the use of endoscopic ultrasonography, a clearer observation of the structure of the layer and the findings of its destruction was made possible, although the authors have not yet conducted them in many cases. This method, however, entails a lot of difficult problems yet to be solved such as the ability and significance of the diagnosis, or problems of its technique and apparatus, demanding a special effort in improvement.
