I have Crohn's disease and in 2015 had 5 ft of small intestine and half of the adjoining colon removed.
Unfortunately my insides were so fucked up that they had to properly open me up (i.e. not keyhole, more doorframe). Then I got sepsis after the operation and was in the high-dependency unit (US equivalent is ICU I think?) for a bit. That was fun. I was there for a few days, but remember about 2 hours of it. My family visited apparently, I had no idea, but I was talking to them, so I'm told.
I couldn't walk for weeks, other than staggering around (which they encourage you to do otherwise the scar tissue will heal too tight). The wound took about 3 months to properly close up, I had a nice deep hole in my abdomen for much of that, you get used to the gory stuff.
I'm generally better now though. Crohn's still dictates much of my daily life though, but you learn to live with it.
