No matter how great a surgeon is, robotic assistance can bring a higher
level of precision to the operating table. The ability to remotely operate a
robot that can hold precision instruments greatly increases the accuracy of
surgical procedures like thoracoscopic surgery, which is used to treat lung
cancer.
Of the two most common types of lung cancer, non-small cell lung cancer
(NSCLC) is a good candidate for surgery because the tumors spread slowly and are
more localized. Since more than 80 percent of people with lung cancer have
NSCLC, surgery is a common treatment.
Lung cancer usually starts when epithelial cells that line the inside of
the lungs rapidly reproduce into cancerous cells, creating tumors inside the
lungs. These tumors have been traditionally removed directly by the skilled
hands of a surgeon. Today, we’re starting to see more tumors being removed by
robots that are controlled by skilled surgeons. This process is known as robotic
assisted lung surgery.
The key benefits of robotic assisted lung surgery are:
It’s minimally invasive and small incisions are used. Traditional lung
surgery procedures utilize a large incision across the chest wall. When using
robotic assisted surgery, the incision is about half as long. The robotic arms
can be maneuvered more intricately, so the incision doesn’t need to be as large.
Often a second incision is made for the removal of tissue.
Patients often experience a faster recovery time. When a patient has a
robotic lobectomy, they’re often back to their normal routine in a week’s time.
Older patients in their 70s and 80s also experience a good recovery with this
type of procedure, which is good news considering they’re usually not great
candidates for open surgeries. The small incisions are responsible for a faster
recovery time compared to the long recovery time after traditional lung
surgery.
There are several robotic assisted procedures used to treat lung
cancer:
Video-Assisted Thoracoscopic Surgery (VATS)
Fewer than 5 percent of thoracic surgeries in the US are performed
robotically. Rush University is one of a few US medical institutions that offer
a full range of robotic-assisted lung cancer procedures, including VATS. In
fact, Rush is known as a leader in VATS.
VATS is the most common type of robotic assisted lung surgery. With this
procedure, one incision is made to insert the surgical instruments for the
removal of tissue, while another incision is used to place the camera. The
surgeon maneuvers the surgical instruments while an assistant operates the
camera so the surgeon can see what’s happening.
The da Vinci Si robotic system
Rush University is now using the da Vinci Si robotic system for lung
surgery, where it was once only used for other, more general surgeries.
How the da Vinci Si robotic system works
A surgeon sits at a console to control a four-armed robot that’s been
positioned above the patient lying on the operating table. The surgeon observes
the scene from a screen that displays images coming from a camera. As the
surgeon moves his or her controls, the robot responds accordingly in real-time,
and the surgical instruments attached to the robotic arms perform the
surgery.
One of Rush University Medical Center’s thoracic surgeons, Gary
Chmielewski, says, “any motion I can do with my hands, the robot can simulate
inside the patient with more precision and less tissue trauma. It all works
together for a better operation that’s easier on the patient.”
Nine years of positive results
A study published in 2014, analyzed the results of different types of
robotic lobectomies for treating lung cancer over a period of 9 years. The study
was designed to evaluate the evolution of technique as well as the robotic
technology. The study found a positive trend in patient outcomes when they opted
for the upgraded robotic systems compared to the standard systems.
Twenty years ago, who would have thought having robotic assisted lung
surgery would become the most popular, most effective option?
If robots can be used to help surgeons remove tumors from lung cancer
patients, what else is possible with robotics? The possibilities are
endless.
