Surgeries are surgeries. Most are completed without a hitch, but others can become complicated and take longer than expected. So, sure some days maybe you can get home in time for dinner, other days not so much if a patient needs you. Further, you may have call responsibilities or rounding responsibilities depending on where you are practicing and how many people you are practicing with. You certainly can choose to operate 2 days a week, but this will ultimately cut into your salary regardless of what the average is. The later you come in, the less likely you can get out early because if you aren't wanting to show up for a first start OR then you have to wait to go second and are thus stuck until they are ready. Most ORs start around 7, so it is probably more realistic to expect to be there 6:00-6:30 because you have to go see the patient before they take them in. So the short answer is no, you can't consistently have that in most cases but you can have a on average decent lifestyle if you are willing to do less cases and thus get paid less depending on call, etc.
