Ugh. Welcome, sorry, and yes..I've had both. I didn't have mine at the same time though because I was stubborn and scared
My gyn/onc/surgeon wanted to do a resection because it was very clear by CT that I had endo on my colon. However, my body messed with me and the months before surgery my colon symptoms improved dramatically. I'm in the healthcare field and for some reason in my mind had just built up a colon resection as just the worst thing ever so I begged him to leave it alone.
One year later I was doing GREAT not having monthly periods (it's the BOMB I tell ya, as my 13 year old would say!) but then my colon symptoms returned horribly...I would wake up on any given day (but usually cyclical and once a month since I still had one ovary) and be so nauseated, horrible abdominal cramping and pain and then vomiting.I lived and worked that way for one year until finally it interfered with some huge birthday plans I had for my husband.
Long story short I ended up with 8" of colon removed/resected. There is no way the endo could have just been cut off of my colon since on pathology report it had completely invaded thru the colon wall.
I was in the hospital for my hysterectomy just overnight. The colon resection was a 6 day hospita stay with an open incision.
This is big surgery. Hopefully your surgeon has not minimized it and acted like you will be back to normal in weeks. Your biggest problem from the hyst will be the lingering fatigue. Hard to describe until you go through it. I was fit and in shape and it still was hard to struggle through. The colon surgery was a bit easier with the fatigue but still about three weeks before I returned to work (I just work part-time anyway).
Let me know if you have specific questions. I feel SOOOOO good now I wouldn't trade it for anything but it is still very big surgery and very scary as you get closer to your surgery date. I'll be here for you
