Occult Dysplasia is Disclosed by Lugol Chromoendoscopy in Alcoholics at High Risk for Squamous Cell Carcinoma of the Esophagus

Abstract

We concluded that individuals who abuse alcohol, smoke and consume 'maté' have a high prevalence of dysplastic lesions that can be better detected by LCE. Esophagi with unstained areas had an eight-fold higher chance of revealing dysplasia than the uniformly stained ones. LCE is an easy and inexpensive method. It improves the detection of dysplasia and should be added to conventional upper GI endoscopy in patients at risk for SCCE.
