The Significance of a Pale Area Via Flexible Spectral Imaging Color Enhancement in the Diagnosis of Esophageal Precancerous Lesions and Early-stage Squamous Cancer

Goals: The main aim of this study was to investigate the significance of a pale area via flexible spectral imaging color enhancement (FICE) in the diagnosis of esophageal dysplasia and cancer. Background: The early diagnosis of esophageal squamous cancer is challenging, and the indication of Lugol’s chromoendoscopy has not yet been well established. Study: The esophageal mucosa of patients at our endoscopic center were sequentially evaluated...
