Robot Assisted Surgery is Linked to The Cost of The Equipment

Robot assisted surgery has much better postoperative outcomes, but its widespread adoption depends a lot on the reduction in the cost of the equipment, say experts.

While the high cost of a robot, which may range between Rs 6-14 crore approximately, may prevent many hospitals from bringing these advanced technologies for the benefit of patients, training of doctors in carrying out these procedures is equally important.

The US based-Vattikuti Foundation has helped prepare 300 robotic surgeons in India since 2011 by bringing in nearly 150 internationally acclaimed experts in the area to hold master classes, performing and observing live robotic surgeries in eight specialities.

“India has over 300 trained robotic surgeons in eight specialities — gastrointestinal, urology, oncology, head and neck, thoracic, gynaecology, general surgery and bariatric,” Mahendra Bhandari, CEO, Vattikuti Foundation, told IANS.

“Patients in India are willingly opting for robotic surgeries for their treatments. Not only patients, young surgeons are leaving the old way (conventional surgeries) and they want to be a robotic orthopaedic surgeon now,” said Bhandari, while addressing orthopaedic surgeons at a master class on computer-assisted joint replacement surgery here on Saturday.

Mahak Baid, an orthopaedic surgeon from Kolkata said that even though robotic-assisted surgery is an advancement, the only thing that needs to be worked upon is cost-effectiveness.

“In a country like India, robotic surgery has to be economically viable. The robot itself costs a lot. So it is not just about the patients, it has to be economically feasible for the hospital as well,” he added.

However, the doctor said robotic surgeries will eventually grow in India.

“I have been using MAKO robots for the last two years and I’m extremely happy with the results. we’re able to do total hips, total knee and partial knee replacements. With robotics, we can do enhanced pre-planning much better than conventional methods,” Thadi Mohan from Amrita Institute of Medical Sciences, Kerala, told IANS.

“After the robotic surgeries, patients recover faster. Chances of revision become much less. Implants will last longer. There is also a change in the mindset of people as there are now a good number of trained surgeons,” he said.

“The only thing holding back robotic-assisted surgeries in India are easy availability. It may take time but eventually it will become cheap and then more people will be able to use it,” he stressed.

Bhandari urged global medical devices and pharma firms to bring their technology to the Indian market expeditiously so that the Indian patients do not have to wait for decades to be able to access the most advanced technology, drugs and implants.

When asked about the future of robotics in India, Brian Davis, Professor of Medical Robotics at Imperial College London told IANS that it cannot grow overnight.

“Many of Indian orthopaedic surgeons have been overseas and trained in countries where high-tech systems are quite normal, so they come in and act as mentor for junior Indian surgeons. So, it’s gradually going to come about that you will have more and more experienced mentors but it’s going to take a while,” Davis added.

Many of the orthopaedic surgeons at the conference said that robotics-assisted bone replacement surgeries are far better and safer because of its consistency and precision than the conventional methods.

Joint replacement surgeons cited published studies that revealed that computer-assisted total knee arthroplasty leads to significantly lower blood loss, infections, inflammation and need for revision surgeries.

“The cost is major factor and rightly so. It takes years to develop this kind of technologies. So by the time they come in practice, the machine costs a lot. Naturally robotic companies with huge investment want to recover their money and India and other developing countries are not their priamary market, Bhandari said.

“The Vattikuti Foundation tries to bring these technologies once they are established. Our model is that we want to exploit the high volumes of the patients in low margins in order to make it cost-effective. And cost should not be major consideration while using a technology, cost is bound to come down the moment the technology used by more and more people,” he said. (IANS)

The ability of cataract surgery to restore sight is well known and a new study suggests that it can make people 48 per cent safer on the road.

Cataracts are normal consequences of aging. They happen gradually over years, as the clear lens inside the eye becomes cloudy.

Cataract surgery replaces the cloudy lens with an artificial lens.

“The results highlight the importance of timely cataract surgery in maintaining safety and continued mobility and independence in older adult drivers,” said study author Jonathon Ng, from the University of Western Australia.

For the findings, presented at the 123rd Annual Meeting of the American Academy of Ophthalmology, the research team tested the driving performance of 44 patients before they had cataract surgery.

The driving simulator assessed a variety of variables: adjusted speed limits, traffic densities, uncontrolled intersections and pedestrian crossings.

Patients were put through the driving simulator after their first surgery and again after the second eye surgery.

After the first, near misses and crashes decreased by 35 per cent; after the second surgery, the number fell to 48 per cent.

“While visual acuity – how well one sees the eye chart – is an important method to assess a person’s fitness to drive, it’s an incomplete assessment,” Ng said.

“Quality of vision is also an important indicator. Improved contrast sensitivity and better night vision improves drivers’ safety on the road,” the study author added.

When considering cataract surgery, the researchers revealed some points to be considered: Can you see to safely do your job and to drive?, Do you have problems reading or watching TV? Is it difficult to cook, shop? Do bright lights make is harder to see? (IANS)
