Diagnostic value of Fuji intelligent color enhancement on vocal leukoplakia and esophageal diseases / 中华消化内镜杂志

ABSTRACT

Objective To study the clinical application of Fuji intelligent color enhancement ( FICE) on the diagnosis of vocal leukoplakia and esophageal diseases. Methods A total of 50 patients suspected with vocal leukoplakia by electronic laryngoscopy were enrolled for undergoing meticulous examination of vocal cords and esophagus using FICE from January 2014 to January 2016. The diagnostic value of FICE for vocal leukoplakia were analyzed. Results Among the 50 patients, 50 lesions were found using laryngoscopy and 52 lesions were found using FICE. There were significant differences between FICE mode and white light mode on the capillary pattern score and lesion boundary resolution score ( all P<0. 05) . The diagnostic coincidence rate of FICE mode with pathology was higher than that of white light mode [ 89. 4％ ( 42/47 ) VS 68. 1％ ( 32/47 ) , P = 0. 01 ] . Among the 50 patients suspected with vocal leukoplakia, 31 combined with gastroesophageal reflux disease, and were given proton-pump inhibitor treatment. In the follow-up after three months, lesions of 16 cases alleviated, 13 cases disappeared, and 2 cases had no significant changes. Conclusion FICE has a higher clinical value than conventional laryngoscopy and white light endoscopy on the diagnosis of vocal leukoplakia.
