About

Confocal laser endomicroscopy detects inflammatory markers undetectable during high definition endoscopy. The investigators aimed to evaluate the role of peridiverticular and colonic mucosa inflammation in the prediction of the complicated diverticular disease using confocal laser endomicroscopy evaluation in the peridiverticular area in consecutive patients.

Full description

Diverticular disease of the colon is a prevalent condition in the western hemisphere. Currently there is an endoscopic classification system for classifying diverticular disease; however, white light endoscopic fails to accurately detect inflammation.

Confocal laser endomicroscopy offers a real-time, in-vivo evaluation of the colonic mucosa, with an adequate correlation to histological findings. The investigators aimed to evaluate the role of peridiverticular and colonic mucosa inflammation in the prediction of complicated diverticular disease.
