 We compare the views of high-resolution magnifying endoscopy and stereoscopic microscopy with the histological findings of upper gastrointestinal tumors which were resected by endoscopic mucosal resection. In all the tumors which were examined(total 12 cases, including 10 cases of early gastric cancer, 1 case of esophageal squamous cell carcinoma, 1 case of Barrett's adenocarcinoma), we were able to observe the features of the capillary vessels of the tumors by high-resolution magnifying endoscopy. In 11 of these 12 cases (excluding the case of esophageal squamous cell carcinoma), we could also clearly observe the fine mucosal patterns of the tumors by stereoscopic microscopy, but the features of the capillary vessels were obscured. The fine mucosal patterns and the features of the capillary vessels which were observed by high-resolution magnifying endoscopy were consistent with the histological findings. High-resolution magnifying endoscopy may be very useful in predicting the histological diagnosis of upper gastrointestinal tumors.
