A Novel Clinically Usable Point Score To Prejudge The Complexity Of Colonoscopy

Colonoscopy is the current common method for management of colorectal diseases, and effectiveness of colonoscopy associate with complication rate. A lot of patients were failed because of technical difficulty, those required more than 10 min to intubate the cecum are consider as difficult colonoscopy, in such condition, specialized equipment or maneuvers may be required for a successful colonoscopy. Thus, it is important to set up a clinical model to predict the technical difficulty of the examination in preoperational stage.
