  • Abstract
  • Look Inside

 The comparison of a histological picture and a ultrasonographic picture of the alimentary tract wall was essential for a diagnosis of the depth of invasion, and it has been evaluated repeatedly since the development of endoscopic ultrasonography. In 1984, Aibe originally reported a five-layer structure of the alimentary tract: the first and second layers were regarded as the mucosal layer, the third layer was as the submucosal layer, the fourth layer was as the proper muscle, and the fifth layer was as the subserosal layer and the serosa. This five-layer structure has been widely used as a fundamental finding. Recently, a higher frequency ultrasonographic machine with higher resolution would enable us to find some more detailed layer structures and the muscular layer of mucosa. The development of new technology demonstrates that the alimentary tract wall would be observed as a nine-layer structure, an elevenlayer structure or a thirteen-layer structure. These investigations would make more precise diagnosis of the depth of invasion.
