Thanks Gator.These are my opinions and I have not studied the literature for each specialty in depth.I appreciate that you are coming from the angle of a general surgeon and admittedly that is where DAVinci hasn't developed its opportunity fully.I have a good friend who is a GYN and does DaVinci. He feels that his patient dissections are easier and that the trocars don't hurt as much as standard laparoscope. He also no longer ever needs an assistant in OR. His patients are discharged same day for hysterectomies!It seems the DaVinci's traction in GYN is gaining ground.So single port surgery is probably the future, but it must be determined to be safe.Since this is a BIG initiative by ISRG, maybe you will become a DaVinci pioneer as well ;)?There is no competitor and none on horizon. There is a huge moat.Agree and IMO, we aint't seen nothing yet. NOTES and nonsternotomy CABG......amazing stuff really!I bet on MAKO because it is opening a new category of procedure, the unicompartment knee.IMO, the unicompartment strategy has failed......it is too small a market as compared to bicompartment disease and the MAKO has made few inroads into bicompartment.Everybody wants to compare MAKO to DaVinci but if they are intellectually honest, they will see they are very different animals with very different strategies........one went after a restricted untapped market and the other cannabilized large and repeated existing markets. ISRG essentially keeps reinventing itself through numerous TALC events.It is for this reason that MAKO's recent stratgeic change to go after total hips and total knees that I think MAKO in back in the game.Gator, many thanks for your kind reply and insight into the medical world. Out of curiosity, you are a Florida gator (aka gator Swamp)?
