On the face of it recreational surgery seems like a risky hobby.

I meant it as a shorthand for the standard gripe of "love my job, hate the paper work.". Many surgeons will also admit that they hate clinic work too, it's so much nicer once the patient is sedated and they can drop their bedside manner.

However there are jobs close to "recreational surgery".

One is surgical assisting. The pay is poor compared to being the primary surgeon, but has none of the patient or bureaucratic responsibility. Retired surgeons often do this, and not because they need the money.

Another is volunteering in the third world. Little bureaucracy and no long term patient contact.
