Robotics and gynecologic oncology: review of the literature

The objectives of this article were to review the published scientific literature about robotics and its application to gynecologic oncology to date and to summarize findings of this advanced computerenhanced laparoscopic technique. Relevant sources were identified by a search of PUBMED from January 1950 to January 2009 using the key words Robot or Robotics and Cervical cancer, Endometrial cancer, Gynecologic oncology, and Ovarian cancer. Appropriate case reports, case series, retrospective studies, prospective trials, and review articles were selected. A total of 38 articles were identified on the subject, and 27 were included in the study. The data for gynecologic cancer show comparable results between robotic and laparoscopic surgery for estimated blood loss, operative time, length of hospital stay, and complications. Overall, there were more wound complications with the laparotomy approach compared with laparoscopy and robotic-assisted laparoscopy. There were more lymphocysts, lymphoceles, and lymphedema in the robotic-assisted laparoscopic group compared with the laparoscopy and laparotomy groups in patients with cervical cancer. Infectious and lung-related morbidity, postoperative ileus, and bleeding or clot formation were more commonly reported in the laparotomy group compared with the other 2 cohorts in patients with endometrial cancer. Computer-enhanced technology may enable more surgeons to convert laparotomies to laparoscopic surgery with its associated benefits. It seems that in the hands of experienced laparoscopic surgeons, final outcomes are the same with or without use of the robot. There is good evidence that robotic surgery facilitates laparoscopic surgery, with equivalent if not better operative time and comparable surgical outcomes, shorter hospital stay, and fewer major complications than with surgeries using the laparotomy approach.
