| [ Summary ] | An increasing incidence of Barrett's cancer has been reported in the West and nearly all cases have been detected in the advanced stage. An increasing incidence of superficial Barrett's cancer has been reported in Japan. We can recognize that the border between the esophagus and stomach is considered to be the lower limit of the longitudinal (palisade) vessels or the upper limit of the gastric fold, which can be observed within the lower segment of the esophagus with conventional endoscopy. Longitudinal vessels can usually also be seen with Barrett's esophagus. Therefore, a diagnosis of Barrett's esophagus can be made by endoscopic examination alone. In our study, all superficial Barrett's cancer cases could be detected by a reddish mucosal change, depressed lesions and protrusions with depressed lesions by employing conventional endoscopy. Most cases were observed in the right aspect of the esophagogastric junction. There were various types of esophageal hiatal hernia, different lengths of Barrett's epithelium and many grades of reflux esophagitis in all cases of superficial Barrett's cancer. In order to detect Barrett's cancer in the early stages, we must note reddish mucosal changes or protrusive, depressed changes in the right aspect of the esophagogastric junction when employing conventional endoscopy. |
