Robotic surgery is an evolution of minimally invasive (laparoscopic) surgery: the surgeon fully controls, in real time, fine instruments and a three-dimensional camera from a console — the system never operates on its own. It offers magnified 3D vision, wristed instruments and tremor filtering, delivering high precision, small incisions and, in suitable cases, less pain and faster recovery. Based on current evidence, outcomes are broadly comparable to laparoscopic surgery; the benefits are mainly technical and ergonomic, at a higher cost. The choice of method is always individualised.
Robotic surgery has become part of everyday practice in modern general and colorectal surgery. Patients often wonder, though, what it really offers compared with laparoscopic or open surgery — and where the benefits end and the marketing begins. Let's look at it plainly and with measure.
What is robotic surgery?
It is an evolution of minimally invasive (laparoscopic) surgery. The surgeon sits at a console next to the patient and controls, in real time, slim robotic arms holding the instruments and a high-resolution camera. Their hand movements are translated to the instruments with precision — filtered of natural tremor and, if needed, "scaled down", so that a large hand movement becomes a very small, controlled movement inside the body. The best-known system worldwide is da Vinci.
One point must be clear: the system does not work on its own. It is not an autonomous robot that "decides" or operates unsupervised — it is a precision tool that faithfully carries out what the surgeon directs.
How it differs from laparoscopic and open surgery
- Open surgery: performed through a conventional incision, giving direct access but usually accompanied by more pain and a longer recovery.
- Laparoscopic: through small ports, with a camera and straight, "long" instruments. Minimally invasive, usually with a two-dimensional image.
- Robotic: follows the same principle as laparoscopic (small ports) but adds three-dimensional magnified vision and wristed instruments that bend like a human wrist.
Laparoscopic and robotic surgery are therefore both minimally invasive; robotic surgery is essentially a technological evolution of the laparoscopic approach.
The main benefits
- Three-dimensional, magnified vision of the surgical field, in great detail.
- Wristed instruments with a range of motion greater than the human hand, making manoeuvres easier in difficult, narrow spaces (e.g. deep in the pelvis).
- Tremor filtering and the ability to scale movements, for greater stability and precision.
- Small incisions: less postoperative pain, smaller scars and a lower risk of an incisional hernia.
- In suitable cases, less blood loss and faster mobilisation.
- Better ergonomics for the surgeon, which can help in complex or lengthy operations.
In which operations it is used
In general surgery, the robotic approach is used increasingly — indicatively:
- Surgery of the colon and rectum — especially in the narrow pelvis, where precision matters for preserving the sphincter.
- Hernia repair: inguinal and incisional / abdominal wall hernias.
- Procedures for hiatal hernia and anti-reflux surgery.
- Gallbladder, spleen and other abdominal operations, when judged appropriate.

What robotic surgery is not
- The "robot" does not operate on its own: every movement is made by the surgeon.
- It is not, by itself, a guarantee of a better outcome; the surgeon's experience and judgement matter more than the technology.
- It is not necessary or appropriate for every operation and every patient.
Safety and what the evidence shows
Robotic surgery shares the documented advantages of minimally invasive techniques. In many operations, clinical outcomes are broadly comparable to laparoscopic surgery, while in certain fields (such as rectal cancer in a narrow pelvis) it may offer technical advantages. At the same time, it has a higher cost and requires set-up time and — like any operation — is performed under general anaesthesia and retains the general surgical and anaesthetic risks. The evidence continues to evolve.
Who is a candidate?
In most cases, anyone suitable for laparoscopic surgery is also a candidate for robotic surgery. Fitness for general anaesthesia is required, and the final choice follows an assessment of the specific case and a discussion with the surgeon.
Recovery
Recovery is usually comparable to laparoscopic surgery and faster than open surgery, with a quicker return to light activities. Avoiding heavy lifting for a few weeks is advised depending on the operation. The exact time is always individualised and determined by your treating physician.
Does the robot operate on its own?
No. The system never works autonomously; every movement is performed in real time by the surgeon, who controls the instruments and the camera from the console. The robot is a precision tool, not an autonomous machine.
Is robotic surgery “better” than laparoscopic?
Based on current evidence, outcomes are broadly comparable. Robotic surgery offers technical and ergonomic advantages at a higher cost; the most appropriate option depends on the operation and the team's experience.
In which operations is it used?
It is widely used in colon and rectal surgery, hernia repair, gallbladder surgery, anti-reflux procedures and other general surgery operations, when judged appropriate.
Is it safer?
It shares the advantages of minimally invasive techniques (small incisions, often less blood loss). However, the general risks of surgery and anaesthesia remain, and safety depends mainly on the experience of the surgical team.
How long does recovery take?
It is usually comparable to laparoscopic surgery and faster than open surgery, with a quicker return to light activities. The exact time is individualised according to the operation and the patient.
