Summary
Brief summary (as posted)
Currently, colonoscopy is a minimally invasive method that can be used as a diagnostic and therapeutic method by endoscopists, gastroenterologists and coloproctologists. Due to the importance and big impact this method has, it is necessary to both optimize its efficiency, and improve its quality, which is one of the main objectives of this protocol. By observing which position its faster and which one also results in fewer complications when performing a colonoscopy without reducing its performance and following all the internationally established quality standards regarding colonoscoscopy. The risk of this protocol implies a risk no greater than the minumum the procedure itself has, and does not generate extra cost for all of the patients subjected to this protocol.
