There are lots of paid medical video sites, e.g. a quick search turns up https://www.madeformedical.com/ and https://cine-med.com/. Presumably these are better curated than YouTube and may even go through some type of peer-review process.
I'll bet every one of them (tries to) absolve themselves from liability through the use of their posted materials. An unverifiable promise that it's somehow a more reliable source than "DuceDangler73s" youtube video on performing a colonoscopy is no comfort.
