Screening for Dysplasia With Lugol Chromoendoscopy in Longstanding Idiopathic Achalasia

Abstract

Achalasia patients with longstanding disease (>20 years) have an increased risk to develop esophageal dysplasia and carcinoma. Endoscopic screening using white light and Lugol chromoendoscopy does not accurately identify precursor lesions for ESCC and therefore cannot be systematically recommended.
