The author had reported about the structure of layers of the gastric wall visualized by means of the ultrasonic endoscope and it's histological solution of these layers. Moreover, the author investigated the structure of layers of the esophageal wall and the colonic wall which could be demonstrated by the method of the ultrasonic endoscope and clarified the histological structure of these layers of the esophageal wall and the colonic wall by compairing endoscopic ultrasonograms with corresponding histology. As the result, the esophageal wall was separated to 5 layers or 7 layers on a endoscopic ultrasonogram both in the resected specimens and the clinical cases. The colonic wall was separated to 7 layers on a endoscopic ultrasonogram both in the resected specimens and the clinical cases. In the histological aspect, the main structure of layers demonstrated by means of the ultrasonoic endoscope was 5 layers both in the esophageal wall and the colonic wall. The histological structure of these 5 layers of the esophageal wall or the colonic wall was as same as that of the gastric wall, except that the 5th layer in the structure of 5 layers changed from the serosal layer to the adventitia in the esophageal wall and the rectal wall. The wall of the esophagus or the colon was recognized as 7 layers when a thin layers was visualized in the 4th layer of the esophageal wall or the colonic wall demonstrated by the method of the ultrasonic endoscope. A thin layer composed of a border echo and the connective tissue between the inner circular muscle and the outer longitudinal muscle. In a resected specimen of the esophageal wall, 9 layers could be observed on a endoscopic ultrasonogram. The histological structure of these 9 layers of the esophageal wall was as same as that of the gastric wall.
