1 /5 Janet Leichliter: Dr Stauffer performed a colonoscopy on me. Three days later I found myself in the ER with acute peritonitis, and potentially hours to live, due to a long gash in my colon. I underwent partial removal of my colon, and had the colostomy bag procedure. When my surgeon contacted Dr Stauffer about this critical event, he said he did not know there was a problem. I NEVER heard a word from him. After suffering for months from the complications of this colonoscopy, I was able to go to Mayo Clinic to get everything up and running again. I was fortunate to find a great surgeon in Marble Falls, who took me in for life saving surgery immediately, and Mayo who reversed the life saving measures performed by my surgeon. I believe people should be aware that this happened when you are considering a colonoscopy to be performed by Dr Stauffer.
