Hi Steve,
I had a colostomy and proctectomy back on June 23, and it has been reasonably trouble-free. From what I understand, a colostomy is generally easier to deal with and has fewer dietary restrictions, but you may get a bit more "variety" 😉
If you're getting flap surgery for the proctectomy, a few tips from my experience are:
After surgery, you may need to lie on one side for a few days to prevent any restriction of blood flow to the flap. A rolled-up towel or something to help you avoid accidentally rolling over helps. I have a profiled memory foam pillow I use at home, and although it was bought for a neck problem, it helps stop me from falling over unintentionally. After your surgery, get up and mobile as soon as you can, but don't overdo it, though. Once you're ready to take a shower, there are plastic skirts you can put around your waist in the shower to help keep the dressings dry. The thing I wish I'd known at the time 🙄 was that it was truly miserable showering half in and half out of the cubicle. Once the dressings come off, they will still weep a bit; some pant liners will protect your pants. After the surgery, things will probably feel a bit weird; everything is very tight, and for me, it kind of felt like I'd had a carrot shoved up my a*#* and then been given a massive wedgie. Over time, the carrot gets smaller and disappears, and the tightness reduces. You'll probably experience some numbness on your butt; this generally improves over time. For me, there was no massive pain, just a bit of discomfort, but it does take a long while to fully heal.
