When people hear “robotic surgery”, it is easy to picture something straight out of a science-fiction film. Despite its name, however, the robot does not operate independently.
“It is actually controlled by the surgeon at the console,” explains Dr Fam Xeng Inn, Consultant Urologist at Picaso Hospital.
Greater Precision in Complex Procedures
Robotic technology provides surgeons with a highly magnified, three-dimensional view and small instruments that move with wrist-like flexibility.
According to Dr Fam, the camera offers approximately 10-times magnification, while the camera and instruments are about eight millimetres wide. This allows surgeons to see and operate with greater precision in narrow, hard-to-reach areas such as the pelvic cavity.
This can be especially useful in prostate surgery and partial nephrectomy, a complex procedure that removes a kidney tumour while preserving as much healthy kidney tissue as possible.
What Could It Mean for Patients?
As robotic-assisted surgery is performed through small incisions, patients may experience less blood loss and a shorter hospital stay compared with open surgery.
Dr Fam shares that patients undergoing robotic partial nephrectomy or radical prostatectomy at Picaso Hospital are usually encouraged to eat and walk the day after surgery, with many discharged by the second or third day.
Although robotic surgery may involve a higher upfront cost, Dr Fam encourages patients to consider its potential longer-term value.
“Imagine if, with robotic surgery, I am able to preserve a kidney for the patient,” he says. “Then the patient can live with normal kidney function and reduce the risk of future haemodialysis.”
However, recovery and outcomes vary depending on the condition, complexity of the procedure and patient’s overall health.
Technology Still Depends on the Surgeon
The robot is a surgical tool and its effectiveness still depends on the person controlling it.
Robotic procedures should be performed by surgeons with the relevant training and experience, supported by a team familiar with robotic-assisted care.
Ultimately, the most suitable surgical approach should be determined through a discussion between the patient and their treating surgeon.
