I had my surgery as a result of toxic megacolon ( I was full of prednisone , mesalamine, opioids, and Humira as well). I went into the hospital with a flare and 2 days later I was on a table. You ever consider the J pouch surgery as an option ? Your entire large intestine and rectum will be removed , but they create an internal pouch with your small intestine and when it’s all said and done you don’t have a bag and go to the bathroom like normal. It takes 3 surgeries to get the j pouch and you have the ileostomy for about a year and the after the last surgery they reconnect the plumbing and since UC only effects the large bowel you will be disease free.
