I have yet to have SRS, but in 2011, I had 2 feet of sigmoid colon removed and an end-to-end anastomosis performed laparoscopically due to severe diverticulitis. This is part of the deal with a colon vaginoplasty.
The week I spent in the hospital from that surgery was BRUTAL, and I would not wish that recovery upon my worst enemy. I'm sort of glad that this type of surgery is not even an option for me now. I just have to REALLY hope they get my SRS right the first time.
Living with a semicolon isn't all that wonderful either. It's "sort of" back to normal now, but I had to literally run to the bathroom occasionally for many months, as things were very unpredictable.
You have been warned!
