  • Look Inside

 Endoscopic findings of esophageal mucosal cancer and the diagnosis of depth of invasion of esophageal cancer through endoscopic ultrasonography were studied and the following results were obtained:

 1) Mucosal changes of esophageal mucosal cancer observed by endoscopy were slight, and endoscopic types of esophageal mucosal cancer showed superficial flat type, erosive type, plateau-like type, and superficial flag+erosive type. In 11 cases of mixed type superficial esophageal cancer, only one case (9.1%) was limited to the mucosa, and the other cases invaded the submucosa.

 2) To find esophageal mucosal cancer, it is important to observe the difference of mucosal coloration carefully, and lugol staining method is zecommended if cancer is suspected.

 3) Normal esophageal wall was visualized in the structure of five layers by means of endoscopic ultrasonography, and the depth of invasion of esophageal cancer could be diagnosed by changes of this five layers even in esophageal mucosal cancer.
