Acetic acid chromoendoscopy for detection of neoplastic Barrett's oesophagus: stepped wedge cluster randomised controlled trial (ACID-trial).
This prospective, open-label, stepped-wedge cluster randomised trial assessed whether acetic acid chromoendoscopy (AAC) improved detection of dysplasia or oesophageal adenocarcinoma during Barrett’s oesophagus…
Why it matters
The trial evaluates an added endoscopic technique in routine Barrett’s surveillance and distinguishes increased visual suspicion from improved detection of confirmed neoplasia.
