Randomized Clinical trial between two positions to initiate colonoscopy, Right Sided vs Left Sided
Objective To assess whether in the colonoscopy, the initial position of the patient in the right lateral decubitus (DLD) translates into advantages such as: shorter examination time or greater range of detection of polyps, compared to the left lateral decubitus (DLI), a position traditionally used. Methodology This is a randomized and controlled clinical trial to be carried out in the city of Bogotá, in the Gastroenterology and Digestive Endoscopy Unit of the Colombia University Clinic, a fourth-level private clinic, a unit in which 7746 colonoscopies were performed in 2017. The study will be carried out over a period of 2 months until the sample is completed. Patients will be randomized to start their colonoscopy in the right lateral decubitus or left lateral decubitus and it would be assessed, the time to reach transverse colon, cecum and comfort perceived by the gastroenterologist and the patient.
