Endoscopic diagnosis of pharyngeal carcinoma by NBI.

摘要: Head and neck cancer, especially pharyngeal frequently co-exist with esophageal but cancer has proven difficult to detect in such cases before its progression an advanced stage. Several recent reports have indicated that narrow-band imaging (NBI) endoscopy magnification is able improve the detection of superficial cancer. NBI a relatively new optical technology based on limiting depth light penetration into mucosa. The recognition these lesions dramatically improved microvascular structure mucosal surface significantly enhanced by NBI. As result, enables more accurate diagnosis increases rate This particular field only been developed years, however, there are still number problems need be addressed future. It will necessary accumulate evaluate resected specimens follow up patients order establish appropriate criteria for curative endoscopic treatment patients. ease using combination this diagnostic concept changes makes suitable worldwide use
