Robotic surgery explained for patients

When you learn that you need an operation and your surgeon says it could be done "with the robot", many questions come up. Does the robot operate on its own? Is it safe? Is it right for me? Below are the answers I give my patients most often, in plain language.

The robot does not operate on its own

This is the most common misunderstanding, so let us clear it up first: the surgical robot makes no decisions and makes no movement without the surgeon. The da Vinci system is an instrument, not an "automatic surgeon". The surgeon sits at a console in the same operating room and controls every gesture in real time; the team stays at the patient's side throughout.

The simplest way to think of it: the robot is an extremely fine extension of the surgeon's hands. It translates the surgeon's movements into smaller, steadier and more precise ones, filters out any tremor, and provides a magnified 3D view of the operating field.

How it differs from open and laparoscopic surgery

In open surgery, the abdomen is opened through a long incision, usually 15–25 cm. In laparoscopic surgery, the operation is performed through a few small incisions, with a camera and long, straight instruments held directly by the surgeon. Robotic surgery also uses small incisions, like laparoscopy, but its instruments have "wrists" that can rotate and bend further than a human hand, and the image is three-dimensional.

Laparoscopy and robotics belong to the same family: minimally invasive surgery. Both are excellent techniques in experienced hands. The difference is felt mostly in narrow, difficult anatomical spaces — such as the pelvis in rectal cancer — where the robot's extra precision matters most.

What it means for the patient

  • Less pain after surgery — incisions of a few millimetres hurt far less than a large one.
  • Faster recovery — getting up on day one, eating again sooner and, as a rule, a shorter hospital stay.
  • Minimal scarring and a lower risk of wound complications, including incisional hernia.
  • Protection of delicate functions — in rectal cancer, precision helps preserve the nerves that control urinary and sexual function.
  • Fewer conversions — an operation started robotically is more likely to be completed minimally invasively, without the need for a large incision.
For the oncological result — complete removal of the tumour and lymph nodes — what matters first is the surgeon's experience and adherence to standards. The robot is an instrument that, in the right hands, makes those standards easier to achieve in difficult situations.

Am I a candidate for robotic surgery?

Robotic surgery can be used for many digestive operations: rectal and colon cancer, gastric cancer, hiatal hernia and reflux disease, abdominal wall hernias, and some liver and pancreatic procedures. Still, there is no one-size-fits-all answer.

The decision is made individually, after a full assessment: the location and stage of the disease, previous abdominal operations, your general health and other conditions (heart, lungs) and, of course, your informed preferences. Sometimes laparoscopy is just as good and simpler; sometimes the robotic approach brings a real advantage. The consultation exists precisely to choose, together, the right option for you.

What happens, step by step

Before surgery

Preparation is the same as for any minimally invasive operation: blood tests, an anaesthetic assessment and sometimes bowel preparation. You will receive clear instructions about your regular medication (especially blood thinners), eating and drinking, and the day of admission.

On the day of surgery

The operation is performed under general anaesthesia. You will not feel or be aware of anything. Duration depends on the procedure — from one hour to several hours for complex cancer operations. Operating time is usually slightly longer than with laparoscopy, without this prolonging recovery.

After surgery

In most cases you will be able to get out of bed and drink fluids on the day of surgery or the next day. Recovery follows the ERAS enhanced-recovery protocol: early eating, early mobilisation and effective pain control. Length of stay depends on the procedure but is generally shorter than after open surgery.

Frequently asked questions

Is robotic surgery "better" than laparoscopy?

Not in absolute terms. Studies show that robotics reduces the risk of conversion to open surgery and, in rectal cancer, can improve the quality of the surgical specimen. For many other outcomes, the two techniques are comparable. What matters is the right choice for each case and the experience of the team.

Is it safe?

Yes. The da Vinci system has been in use for more than two decades, in millions of operations worldwide. It has multiple built-in safety systems, and the surgeon can switch to laparoscopy or open surgery at any moment if the situation requires it.

Who actually operates?

Your surgeon — certified on the da Vinci console — from start to finish. No part of the operation is performed "automatically".

Will the scars show?

Incisions are usually 8–12 mm. If the specimen has to be removed, one additional small incision is used, placed as discreetly as possible. Once healed, the marks are usually hard to see.

The bottom line

Robotic surgery is an advanced form of minimally invasive surgery in which the surgeon controls every gesture at all times. It means less pain, faster recovery and added precision in difficult areas. Technology alone does not heal — the surgeon who masters it does — and the right decision is made together, at the consultation.
