Robotic Surgery

What is Robotic Surgery?

Robotic surgery is increasingly being recognized as the new minimally invasive surgery frontier in various surgical disciplines, including bariatrics and general surgery. This technological advancement is transforming the way surgeries are performed, offering numerous benefits and promising a future with even more innovative capabilities. In particular with the newer robotic systems, there will be even more AI (artificial intelligence) integration to help enhance decision-making, improve outcomes, and potentially allow for more autonomous functionalities. Another area of advancement would be in Augmented reality (AR) where safety in operations are further improved through better visualisation and simulation capabilities.

Dr Cheng is an Accredited Sydney based robotic Upper GI/ Bariatric and Hernia surgeon who can easily tailor the best surgical approach for your operative needs.

Why We Believe in Robotic Surgery

  • Precision:
    • Robotic systems offer enhanced precision and control, allowing for more intricate movements and better outcomes.
  • Reduced Trauma:
    • Smaller incisions result in less trauma to the body, leading to quicker recovery times and less scarring.
  • Enhanced Visualization:
    • High-definition, 3D imaging provides surgeons with a better view of the surgical area.
  • Flexibility:
    • Robotic arms can rotate and move in ways that human hands cannot, offering greater flexibility during surgery.
  • Ability to deal with abdominal wall compliance:
    • This is particularly important in bariatrics and hernia surgery where we can be fighting the abdominal wall during the operation. The robot helps to facilitate a smoother operation.
  • Suturing Angles:
    • The robot offers more flexibility in terms of suturing which makes demanding surgeries like bariatric operations easier when it comes to creating surgical joins.
  • Reduced Risk of Complications:
    • Improved precision and control can lead to fewer surgical complications, such as infections or bleeding.

Why We Are Excited with Robotic Surgery

What is Some of the Evidence Available?

Despite increased costs, robotic approach may represent an added value in more complex cases such as Super Morbidly Obese patients and complex abdominal wall hernias.


This network meta-analysis suggests that both LapRYGB and RoRYGB appear to be safer compared to OpenRYGB with regard to 30-day mortality, overall complication rate, surgical site infection rate, and pulmonary complication rate



Robotic bariatric surgery may be a promising technique to decrease most postoperative outcomes compared to the traditional technique. However, further research is needed to fully understand the long-term benefits and cost-effectiveness of this technology


A comparison of propensity score-matched cohorts of emergent/urgent robotic-assisted and laparoscopic cholecystectomy indicates that robotic-assisted cholecystectomy is a safe alternative to laparoscopic cholecystectomy, and that both have superior outcomes to open cholecystectomies


Robotic ventral hernia repair demonstrated potential benefits, including shorter hospital stay, lower recurrence and lower reoperation rates
