Robotic Surgery Controversies Simmer
I'm involved in a protracted and good-natured (I hope) debate about the merits of robotic surgery with a University of Pittsburgh urologist named Ben Davies. Today he tweeted the following (with translation for the Twitter averse):
“I would love for a $ISRG [stock symbol for Intuitive, makers of the robot] MD hater (like @Skepticscalpel) to actually watch 10 open RRPs [radical retropubic prostatectomies] then watch a 10 robotic RRP. Call me with results”
Dr. Davies is a rabid proponent of robotic prostatectomy and by his own admission, is pretty good at it.
I will admit that robotic surgery may indeed be better than open or standard laparoscopic prostatectomy. There is a lot of level 3 evidence to suggest that.
However, a PubMed search today fails to reveal any randomized trials of robotic vs. open or laparoscopic prostatectomy. All research on this subject has been retrospective with the potential flaws associated with that type of study, selection bias, unknown confounding variables, unblinded authors, etc.
In Australia, randomized study of sorts is in progress comparing 200 robotic prostatectomies done by a single surgeon to 200 open prostatectomies done by a different surgeon. A search of ClinicalTrials.gov yields only one other prospective trial in progress. It is a “medico-economic” one from France. There is a trial about whether or not a drain should be used in robotic prostatectomy which assumes that the issue of whether robotic is better than open or standard laparoscopic is settled.
