Just had my first a few weeks ago, at 55 had two polyps test negative so good for 5 years. Working in the heath care field I have seen lots of change in the equipment used in this procedure. Cidex was used to clean the scopes in the beginning, now we use a machine called a medivator that cleans and sterilizes the scope inside and out. The scopes are very clean with no reside left on them unlike the cidex. The newer scopes are HD and have the ablility to change light color to a mode called NBI which is a blue that helps to find cancer. If they use the CO2 regulator and gas instead of air you will have little to no gas afterwards, I had none and we have been using C02 which is absorbed by the body for years now. The scope alone without all the supporting equipment runs 18k and the life expectancy is about 3 years with heavy use. They have air and water channels a biopsy channel, video camera and light channel along with cables that control the bending end, very complex piece, fluid migrations into the electronics is the most costly, about 8k to fix.
