The Place of the Surgical Robot for Expert Laparoscopists

Between 1986 and 1992, we have reiterated in various publications that “wherever in the body a cavity exists or a cavity can be created, operative laparoscopy is indicated and probably preferable […the predominate limitation to operative laparoscopy is the surgeon’s imagination.”1-8 In support of these statements, we have presented and published the first case series of laparoscopic bowel,4-12 bladder13-14 and ureter2 resections and reanastomosis, as well as the first paraaortic and pelvic node dissection, radical hysterectomy,15 and sacral colpopexy.13
In the past, operative laparoscopy and its proponents have faced significant opposition.16-17 More recently, in 2004, a randomized study of laparoscopically assisted and open colectomy for colon cancer in the New England Journal of Medicine, demonstrated beneficial results in favor of laparoscopy, even for bowel resection.18 The editor of the journal, Dr. Pappas, wrote, “Surgeons must progress beyond the traditional techniques of cutting and sewing, to a future in which minimal access to the abdominal cavity are only the beginning.”18 Surprisingly, this proclamation came nearly sixteen years after the first reported laparoscopic bowel resection in 1988.4 Currently, there is a substantial body of evidence to support the laparoscopic approach as the preferred method for practically all procedures, including surgery for malignancies. It is admirable that even those who in the past opposed operative laparoscopy now are endorsing it.19
NEED FOR INCREASED USE OF LAPAROSCOPY IN THE COMMUNITY
Despite the clear advantages of minimally invasive surgery, the majority of procedures performed in the community, such as hysterectomies and bowel resections, still are done by laparotomy. This preference for open procedures is likely due to the lack of trained endoscopic surgeons, the difficulty in obtaining proper instruments and the long learning curve of operative laparoscopy. The recent advent of computer enhanced technology, more sophisticated instruments and energy sources as well as new inventions will provide the bridge necessary for those in the surgical community to incorporate laparoscopic surgery into their practice.
Since our collaborative work with robotic pioneers Ajit Shah and Phil Green from the Stanford Research Institute who developed the Da Vinci robot in the 1990s, many have successfully applied this technology to various fields. The “robot” enables visualization of the surgical field in three dimensions, eliminates tremors, has more wrist motions, and decreases the learning curve for suturing all while allowing the surgeon to sit and operate in a 3D environment. Using the advantages of the robot, community surgeons who might otherwise feel uncomfortable with laparoscopy may be able to convert some of their laparotomies to laparoscopies. Thus, the robot has the potential to bring a wave of change in the pattern of surgery with more and more open surgeries being performed as laparoscopies.
PATIENT OUTCOMES: IS THE ROBOT (DA VINCI SYSTEM) ASSOCIATED WITH BETTER RESULTS?
To date, patient outcomes after minimally invasive surgeries with and without the robot in the hands of experienced laparoscopists who are equally experienced in the use of the robot have been the same.20-27 Recently, we published a retrospective cohort study of 78 patients who underwent treatment of endometriosis, 40 by robot assisted laparoscopy (RAL) and 38 by standard laparoscopy (SL). We were surprised to find that RAL did not have better outcomes than SL, as we have always believed if you can see more and see better you can do more and do better.23 Adding the robot to laparoscopy did not produce any advantage when performing a hysterectomy, radical hysterectomy, myomectomy or in the treatment of endometriosis when analyzed with respect to patient outcomes.20-23 Thus, one might argue that an expert laparoscopist may not need to add the Da Vinci robot to his or her armamentarium to be able to perform operative laparoscopy. That said, we would encourage even the expert laparoscopist to explore the use of thistechnological advance in their surgical practice. If one has only a hammer one will see only nails to pound. It remains imperative that we, as surgeons, continue to explore each new advance and push our discipline further forward.
In summary, the Da Vinci system is an enabling device. It can assist the community surgeon who cannot effectively perform operative laparoscopy with straight instruments and convert their laparotomies to laparoscopies. By contrast, the expert laparoscopist may not need to add the Da Vinci System to accomplish surgical goals they can already reach with standard instruments during laparoscopy. The final outcome of surgery depends more on the surgeon than on the instrument she or he uses. However, we would encourage our colleagues to explore each new technology, including the Da Vinci System, thereby possibly enhancing not only their own practice, but the utility of the technology itself.
