Robotic surgery

What is robotic surgery?

Robotic surgery, also called robot-assisted surgery, is a surgical technique in which doctors use robotic technology to perform an operation. The robotic system helps the surgeon control surgical instruments, plan movements, and perform certain procedures with greater precision. Robotic surgery is used in several medical specialties, including orthopedics, urology, gynecology, and cancer treatment.

How does robotic surgery work?

Robotic surgery uses advanced technology to help surgeons perform complex procedures with better control and accuracy. The exact process depends on the type of surgery and the robotic system used. However, most procedures follow these steps.

1. The surgeon prepares for the procedure

Before surgery, the medical team reviews the patient's health, medical history, and test results.For certain procedures, doctors use CT scans, MRI scans, or other imaging tests to plan the operation. In robotic knee replacement surgery, for example, the surgeon can use imaging or information collected during the operation to plan the position of the knee implant.

2. The patient receives anesthesia

The patient receives anesthesia based on the procedure and their medical condition. Some surgeries require general anesthesia, while others can be performed using regional anesthesia. The anesthesia team monitors the patient's condition throughout the procedure.

3. The surgeon positions the robotic equipment

The surgical team prepares the robotic system. For many soft-tissue procedures, the surgeon makes small incisions and inserts a camera and surgical instruments. The camera provides a detailed view of the surgical area. For orthopedic procedures such as robotic knee replacement, the robotic system helps the surgeon plan and guide bone preparation and implant placement.

4. The surgeon performs the operation

The surgeon controls or guides the robotic instruments to perform the procedure. Depending on the system, robotic technology can help with precise movements, surgical planning, or keeping instruments within planned boundaries. 

5. The patient receives postoperative care

After the procedure, the medical team monitors the patient's recovery. Doctors check for pain, bleeding, infection, and other possible complications. The patient receives instructions about medication, wound care, follow-up appointments, and physical activity. The length of the hospital stay depends on the type of surgery and the patient's recovery.

Is robotic surgery covered by group health insurance in India?

Yes,  group health insurance in India can cover robotic surgery when the procedure meets the policy's coverage conditions. The insurer checks the medical necessity of the procedure, the policy terms, and any applicable treatment limits.

The Insurance Regulatory and Development Authority of India (IRDAI)  has addressed modern treatment methods, including robotic surgeries, through its group health insurance guidelines. Insurers must follow applicable regulatory requirements, but the amount payable under a specific policy still depends on its terms and conditions.

What are the different types of robotic surgery?

Robotic surgery is used across several medical specialties. The type of robotic system and its role depend on the procedure.

Here are some common types of robotic surgery in India.

1. Robotic orthopedic surgery

Robotic orthopedic surgery is used for certain procedures involving bones and joints.

Common examples include:

• Robotic knee replacement surgery
• Robotic hip replacement surgery
• Selected spine procedures

In robotic knee replacement surgery, the technology helps surgeons plan and position the artificial knee joint.

2. Robotic urological surgery

Robotic surgery is widely used for certain conditions affecting the urinary system.

Common procedures include:

• Prostate removal
• Kidney surgery
• Partial kidney removal
• Selected bladder surgeries

For example, robotic-assisted prostate surgery allows the surgeon to operate in a small area of the pelvis using specialized instruments. This approach can support precise movements during complex procedures.

3. Robotic gynecological surgery

Robotic surgery is also used to treat certain conditions affecting the female reproductive system.

Common procedures include:

• Hysterectomy
• Fibroid removal
• Selected endometriosis procedures
• Certain gynecological cancer surgeries

The robotic system can help surgeons operate in areas that are difficult to access using conventional instruments.

4. Robotic cancer surgery

Doctors use robotic systems for selected cancer surgeries.

These include procedures involving:

• Prostate cancer
• Kidney cancer
• Colorectal cancer
• Certain head and neck cancers
• Selected gynecological cancers

Robotic assistance can help surgeons operate in confined spaces and perform complex movements. However, the choice of surgical approach depends on the type of cancer, its stage, and the patient's overall health.

5. Robotic cardiac surgery

Robotic systems are used for selected heart procedures, including certain heart valve surgeries. In suitable cases, robotic assistance allows surgeons to operate through smaller incisions instead of opening the chest through a traditional large incision. However, not every cardiac condition can be treated using robotic surgery.

6. Robotic general surgery

Robotic systems are also used for certain general surgical procedures.

Examples include:

• Hernia repair
• Gallbladder removal
• Selected gastrointestinal surgeries
• Certain colorectal procedures

The surgeon decides whether robotic assistance offers a meaningful benefit compared with conventional laparoscopic or open surgery.

What are the benefits of robotic surgery?

Robotic surgery offers several potential benefits:

1. Greater surgical precision

Robotic systems can help surgeons perform controlled movements in small or difficult-to-reach areas. Some systems also filter hand tremors and provide a detailed view of the surgical area. This can be useful during procedures that require careful movement around delicate tissues.

2. Smaller surgical incisions

Many robotic procedures use smaller incisions than traditional open surgery. Smaller incisions can reduce damage to surrounding tissues and help limit postoperative discomfort. However, not all robotic surgeries use small incisions.

3. Reduced blood loss

Certain robotic procedures are associated with lower blood loss compared with open surgery. This is partly because minimally invasive techniques can reduce the amount of tissue affected during an operation. The actual benefit depends on the procedure and the patient's condition.

4. Shorter hospital stays

Patients undergoing some minimally invasive robotic procedures can leave the hospital sooner than patients undergoing open surgery. However, hospital stays depend on the type of operation, complications, and recovery progress.

5. Faster recovery

Smaller incisions and reduced tissue damage can help some patients return to their daily activities sooner. However, recovery is not always faster than conventional laparoscopic surgery. Patients still need to follow medical advice, attend follow-up appointments, and complete rehabilitation when required.

What are the risks and disadvantages of robotic surgery?

The robotic system can support the surgeon, but it cannot eliminate complications.

1. Injury to nearby organs or tissues

During surgery, there is a risk of injury to nearby organs, blood vessels, nerves, or other tissues. The surgeon takes precautions to reduce these risks, but complications can still occur.

2. Anesthesia-related complications

Robotic procedures can involve risks related to anesthesia. These include allergic reactions, breathing problems, and other complications. The anesthesia team assesses the patient's medical condition before surgery.

3. Longer operating time

Some robotic procedures take longer than conventional surgery, particularly when the surgical team is less experienced with the system. The additional time can involve equipment setup and preparation.

4. Equipment-related limitations

Robotic systems are advanced medical devices, but technical problems can occur. If the equipment cannot be used safely, the surgeon can continue using another surgical approach.

5. Higher treatment costs

Robotic surgery often costs more than conventional surgery because hospitals invest in expensive equipment, maintenance, and specialized instruments. These additional expenses can increase the final hospital bill.

Robotic surgery vs. traditional surgery: What's the difference?

The main difference between robotic surgery and traditional open surgery is how the surgeon accesses and operates on the affected area. Robotic surgery uses technology to support surgical movements or planning. Traditional open surgery allows the surgeon to access the surgical area directly through a larger incision.
