| [ Summary ] | Magnifying endoscopy is indispensable for the diagnosis and staging of esophageal cancer. Magnified observation makes it possible to assess microvascular patterns on the surface of the esophageal mucosa. Microvascular patterns can lead to a diagnosis of cancer the depth of invasion, without histopathological assessment through biopsies or iodine staining, which may produce adverse reactions such as heartburn or nausea. The rate of accurate diagnosis of EP and LPM cancer, which is an appropriate target of endoscopic therapy, is very high. As a result, we can observe small MM and SM1 invasion sites in cases of flat type superficial esophageal carcinoma. Moreover, type 4R vessels, as reported by Arima permitus to infer the development and invasion patterns of tumors related to lymph node metastasis. Whereas magnifying endoscopy with acetic acid or narrow band imaging (NBI) displays minute surface structures and/or microvascular architecture, these modalities are very useful to detect and determine the extent of flat type Barrett's adenocarcinoma. |
