Do let us know what Dr Reddy suggests!
You will have a period of time with an ostomy, since I'd doubt you are a candidate for a 1-step surgery. I actually wound up with 2 separate ostomies, and had to deal with the bag for almost half a year. It is hard, but you'll have no choice but to manage. The loop ostomy (my second one) was much, much harder than the end ostomy I got when the colectomy was done.
You will feel much better once the diseased colon is gone.
