Can you remove cysts and do a tummy tuck at the same time?

I have lost over 50 pounds. At the same time I have chronic eczema and an L4 spondylolisthesis grade 3. I had lumbar surgery at the Unv of Miami with Dr. Barth Green, neurosurgeon. I do not want another spinal surgery. I feel the removal of the cysts and extra skin will help my back without the complex rods and screws procedure that was recommended by the University of Miami, Dr. Steven Vanni. Dr. Michael Zeide, Orthopedic Surgeon, Boca Raton said I should not have the surgery at all, much too risky. I have to investigate this option. Thank you, in advance, for your help.
