My review is from 20+ years ago, as I am still having intestinal problems from having suffered colon perforation during routine colonoscopy by Dr. Frank, and consequent sepsis; near death situations; a long hospital stay; and 4 extensive surgeries in the 2 years following. Too late, I discovered that Dr. Frank, even at that time, was well known for many perforations on patients, His history was well known by my attending nurses and hospital personnel, even the admission office personnel. Apparently he is not still practicing; I just wonder how many deaths he caused in past years. I feel fortunate to be alive and fairly healthy after what I endured due to his ineptitude.
