Don't despair on the ultimate fix yet.
I have a very good friend who had a really dreadful case of diverticulitis, was in the ICU on a respirator for weeks, septic, multiple surgeries, came very, very close to dying. Was ultimately released from the hospital with an ostomy. After several months, that one was replaced with another in order to take pressure off the first. Her innards were a mess. Significant amounts of intestine removed, tons of scar tissue, much damaged tissue. Only one surgeon in our area would agree to try to reverse the ostomy. It was touch and go, but she succeeded.
Your husband must be very, very disappointed, but I hope things work out for him in the long run.
