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 IntuitiveIntuitive (NASDAQ:ISRG),
headquartered in Sunnyvale, California, is a global leader in
minimally invasive care and the pioneer of robotic surgery. Our
technologies include the da Vinci surgical system and the Ion
endoluminal system. By uniting advanced systems, progressive
learning, and value-enhancing services, we help physicians and
their teams optimize care delivery to support the best outcomes
possible. At Intuitive, we envision a future of care that is less
invasive and profoundly better, where disease is identified early
and treated quickly, so that patients can get back to what matters
most.
About da Vinci Surgical SystemsThere 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.

Important Safety InformationSerious
complications may occur in any surgery, including da Vinci surgery,
up to and including death. Serious risks include, but are not
limited to, injury to tissues and organs and conversion to other
surgical techniques which could result in a longer operative time
and/or increased complications. For summary of the risks associated
with surgery refer to www.intuitive.com/safety.
For product intended use and/or indications for use, risks,
cautions, and warnings and full prescribing information, refer to
the associated user manual(s) or visit
https://manuals.intuitivesurgical.com/market.
Individual outcomes may depend on a number of factors—including
but not limited to—patient characteristics, disease
characteristics, and/or surgeon experience.
