We shouldn't assume this is adenomyosis. In your previous post you describe bad periods since you were a teen, constant pelvic pain, back ache, bloating, exhaustion and sciatica/restless leg. These are symptoms of adeno but also those of endometriosis behind the uterus affecting the bowel.
The surgeon says he didn't find any 'obvious' endo which suggests he didn't look far. In general gynaecology it is common not to look further than the uterus and ovaries but the most problematic endo is not obvious unless thoroughly searched for.
Once the report is back with your GP (may take a couple of weeks) come back and let us know what it says as to where he looked. These reports can be very revealing not so much for what they say but for what they don't say. Since your symptoms are likely to continue I suggest you get a referral to a BSGE endo centre if you are in England. They will do more thorough investigations.
In the meantime let yourself rest and recover. Incidentally exhaustion and restless leg are symptoms of anaemia. I suggest you get your iron and vitamin B12 levels checked.
The shoulder pain is just irritation of the nerves on the diaphragm from the lap gas as I expect you know. This should pass so I don't expect you will need a referral for that as has been suggested.
