Comparative Efficacy of Water & Indigo Carmine vs. Water or Air Method on Adenoma Detection Rate (ADR) - a Randomized Controlled Trial (RCT)
Adenoma detection rate (ADR) is a quality indicator of colonoscopy performed for colorectal cancer screening. Population studies have shown that traditional air colonoscopy fails to eliminate post screening colonoscopy cancers or…

Barrett's Esophagus
"Acetic Acid Chromoendoscopy in Barrett's Esophagus Surveillance
Neoplasia in Barrett's esophagus could be missed during routine random biopsies. We propose a study using chromoendoscopy with Acetic Acid to increase the yield of biopsies in detecting neoplasia.
