Abstract

Chromocolonoscopy has become an important diagnostic procedure. Concentric circle sign, concentric circle pattern of colonic mucosa, is a specific finding for diverticulum and prediverticulum. Dye retention enema is very effective for the visualization of this sign. Endoscopical differential diagnos between inverted diverticulum and polyp is easy by recognizing concentric circle sign. Further studies will be necessary to clarify the mechanism of concentric circle formation.
