| [ Summary ] |
The long-term prognosis of esophageal cancer patients has been considerably improved by recent advancements in endoscopic devices and diagnostic/therapeutic techniques. Endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD) and chemoradiotherapy (CRT) are low invasive treatments that preserve a patient's esophagus. Adequate follow-up surveillance endoscopy after initial intervention is especially critical because esophageal, head and neck cancers can frequently occur as multiple lesions both synchronous and metachronous. It has become necessary, therefore, to be able to thoroughly observe the pharynx in high risk esophageal cancer patients and the use of narrow-band imaging (NBI) is an essential procedure at the present time. Although Lugol chromoendoscopy remains the gold standard method for detection of early esophageal cancer, NBI is now considered comparable to Lugol staining. The multiple metachronous esophageal cancers must be controlled to ensure long-term survival. |
