Just wondering if a colonoscopy is considered a sterile procedure. I didn't think so because there did not seem to be a sterile field for the one I observed. I am sure the equipment has to be sterile though. Does anyone know for sure?
Nope, the GI tract is not sterile, so a colonscopy is not a sterile procedure. If an incision were made somewhere, like for a PEG tube placement, the skin part would be done with sterile technique, but not the scope part.
