The transnasal FICE system enables clear visualization of palisade vessels and provides better contrasting images of the demarcation between the BE mucosa and the gastric mucosa, and thus contributes to easier diagnosis of endoscopic BE.

NSAIDs can induce injuries in the small bowel even in patients without any lesions in both the stomach and colon.

Metastasis of breast cancer to the esophagus has been reported but is rare. It is often difficult to diagnose metastases of breast cancer to the esophagus because they are often located in the submucosa and covered with normal mucosa. Although several methods have been reported in order to obtain specimens for pathological diagnosis, the adverse effects including bleeding and perforation were considerable problems. We report a case of a patient with esophageal stricture due to metastatic breast cancer to the esophagus. Pathological diagnosis was successfully obtained using endoscopic mucosal resection of the esophagus.

Small-caliber endoscopy with the FICE system provides better color contrast of depressed-type early gastric cancers than conventional small-caliber endoscopy, and the FICE system may facilitate the diagnosis of this type of cancer as a new endoscopic modality.
