Number of the day - 230 clinical studies on da Vinci analyzed
"The peer-reviewed Annals of Surgery published a meta-analysis of 30-day surgical outcomes across seven oncological surgical procedures, comparing robotic, laparoscopic, and open surgical approaches. The study covered a 12-year timeframe and analyzed 230 studies from 22 countries: 34 randomized controlled trials, 74 prospective studies, and 122 database reviews. Each surgical approach represented more than a million procedures.
The meta-analysis, conducted by scientists from Intuitive and Massachusetts General Hospital, demonstrated multiple benefits for robotic surgery using Intuitive’s da Vinci system as compared to laparoscopy and open surgery.
“Robotic surgery with da Vinci showed fewer conversions, less blood loss, fewer blood transfusions, fewer readmissions and reoperations, and a shorter length of stay after 30 days,” said Intuitive Executive Vice President and Chief Medical Officer Myriam Curet, MD.
“The editors at the Annals of Surgery thoroughly scrutinized and peer-reviewed this study prior to acceptance,” said Curet. “The quality of scientific data we are seeing after decades of robotic surgery underscores the value that the da Vinci robotic approach continues to have for improved surgical care.”
Notable study results included:
- Da Vinci robotic cases were 56 percent less likely to convert to open surgery versus laparoscopy.
- Da Vinci robotic cases saw less blood loss versus open, comparable blood loss with laparoscopy.
- Da Vinci robotic cases were 21 percent less likely to require blood transfusions versus laparoscopy and 75 percent versus open.
- Da Vinci cases were 10 percent less likely to experience 30-day postop complications versus laparoscopy; 44 percent versus open.
- Da Vinci cases saw a half-day savings in hospital stay compared to laparoscopy and 1.9 days compared to open.
- Operative time for da Vinci cases was 17.7 minutes longer than laparoscopy and 40.9 minutes longer than open.
“The data presented in our study describes the value of robotics in both the controlled clinical setting of randomized controlled trials and in the ‘real-clinical-world’ of population-based studies,” said Rocco Ricciardi, MD, MPH, lead study author and chief of colon and rectal surgery at the Massachusetts General Hospital.
“Ultimately, demonstrating population-based gains with robotics allows us to determine value of robotic procedures for the average person who might need surgery.”
Traditional minimally invasive surgery offers many benefits but presents several technical limitations—notably lower quality vision and depth perception, camera instability, limited range of motion and dexterity due to the straight and rigid hand-held instruments, and it can take a severe physical toll on the surgeon.
Intuitive technology introduced in the da Vinci surgical system has helped surgeons overcome many of those technological limitations via advanced 3DHD vision, wristed instrumentation, and greater precision, especially in deep, limited, or narrow areas of the body such as the chest, abdomen, and pelvis.
There have been numerous studies comparing perioperative outcomes between robotic, laparoscopic, and open surgery but they have focused on individual procedures, which result in procedure-specific evaluations.
Intuitive’s study in the Annals of Surgery looked at randomized controlled trials, prospective cohort, and database studies published within the last 12 years, and it shows multiple benefits for robotic surgery using the da Vinci system compared to laparoscopic and open surgery, which may be useful to decision makers who are considering the use of robotics in a multi-specialty setting.
The study scope focused on 30-day outcomes specific to oncology procedures that often require deep and narrow surgical access. It did not review oncologic outcomes."
