Meta-analysis published in Annals of Surgery shows benefits of da Vinci surgery across seven oncologic procedures compared to laparoscopic and open
A comprehensive meta-analysis published in Annals of Surgery has demonstrated significant benefits of da Vinci robotic surgery compared to laparoscopic and open surgical approaches. The study analyzed 230 studies from 22 countries over 12 years, including randomized controlled trials, prospective studies, and database reviews.
Key findings show that da Vinci robotic cases were 56% less likely to convert to open surgery versus laparoscopy, experienced 21% fewer blood transfusions versus laparoscopy and 75% versus open, and had 10% fewer 30-day postop complications versus laparoscopy and 44% versus open. Patients also experienced shorter hospital stays, though operative times were longer than both traditional approaches.

Lo studio ha analizzato 230 studi provenienti da 22 paesi nell'arco di 12 anni, inclusi trial controllati randomizzati, studi prospettici e revisioni di database.
I risultati chiave mostrano che i casi robotici da Vinci avevano il 56% in meno di probabilità di convertire a chirurgia aperta rispetto alla laparoscopia, hanno richiesto il 21% in meno di trasfusioni di sangue rispetto alla laparoscopia e il 75% in meno rispetto alla chirurgia aperta, e hanno presentato il 10% in meno di complicazioni post-operatorie a 30 giorni rispetto alla laparoscopia e il 44% rispetto alla chirurgia aperta. I pazienti hanno anche sperimentato periodi di degenza ospedaliera più brevi, anche se i tempi operatori erano più lunghi rispetto a entrambi gli approcci tradizionali.

L'étude a analysé 230 études d'22 pays sur 12 ans, y compris des essais contrôlés randomisés, des études prospectives et des revues de bases de données.
Les résultats clés montrent que les cas de chirurgie robotique da Vinci avaient 56 % de chances en moins de se convertir en chirurgie ouverte par rapport à la laparoscopie, ont subi 21 % de transfusions sanguines en moins par rapport à la laparoscopie et 75 % par rapport à la chirurgie ouverte, et avaient 10 % de complications postopératoires à 30 jours en moins comparés à la laparoscopie et 44 % par rapport à la chirurgie ouverte. Les patients ont également connu des séjours hospitaliers plus courts, bien que les durées opératoires aient été plus longues que pour les deux approches traditionnelles.

Insights
Analysis included 230 studies—a mix of randomized, prospective, and database research
SUNNYVALE, Calif., Dec. 05, 2024 (GLOBE NEWSWIRE) -- (NASDAQ:ISRG)
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.

About da Vinci Surgical Systems
There are several models of the da Vinci Surgical System. The da Vinci surgical systems are designed to help surgeons perform minimally invasive surgery and offer surgeons high-definition 3D vision, a magnified view, and robotic and computer assistance. They use specialized instrumentation, including a miniaturized surgical camera and wristed instruments (i.e., scissors, scalpels, and forceps) that are designed to help with precise dissection and reconstruction deep inside the body.
