1999 had colon removed due to ulcerative colitis by another dr. Due to some complications my wife researched other doctors and found a doctor who teaches other doctors and was lucky enough to get Dr. Welton at Stanford. He did a reversal surgery approx. 18-24 mos. after my original surgery. I started having some issues and he strongly suggested I have a permanent bag attached. In 2006 he performed that surgery. It is now 2019. Life is very good and no issues.
