What does the robot offer compared to laparoscopy?
The robotic system does not operate independently; it is completely controlled by a surgeon sitting at a console a few meters from the patient. The difference from conventional laparoscopy is in two things. Firstly, the image is three-dimensional and enlarged by approximately ten times, which makes it possible to distinguish structures that are difficult to see on a flat monitor. Secondly, the instruments have a wrist hinge and reproduce the movements of the hand inside the body, whereas straight laparoscopic instruments are limited to four degrees of freedom. The system also filters natural hand tremors and scales movements.
This is especially useful where it is necessary to work in a narrow space and to accurately preserve fine structures. The classic area is radical prostatectomy for prostate cancer, where urinary continence and erectile function depend on the careful isolation of neurovascular bundles. The robot is also used in kidney resection with organ preservation, in gynecology for hysterectomy, myomectomy and endometriosis, in colorectal surgery for rectal cancer, in bariatric and thoracic surgery.
Limitations are also real: the cost of the operation is higher, preparing the system takes time, and with a massive adhesive process and in emergency situations, the method is not always applicable. The proven benefits relate primarily to functional results and reduced blood loss, while oncological effectiveness, when performed correctly, is comparable to open and laparoscopic surgery.
Advantages of laparoscopic approach
Instead of a 10–20 centimeter long incision, 3–4 punctures ranging in size from 5 to 12 millimeters are made. This reduces pain after surgery, reduces the need for painkillers, speeds up the recovery of bowel function and allows you to be discharged much earlier.
The cosmetic result is no less important: puncture marks become almost invisible over time. The incidence of postoperative hernias and adhesions is also reduced, since the abdominal wall and internal organs are less injured.
When laparoscopy is not possible
Limitations include a pronounced adhesive process after previous operations, severe heart and lung diseases in which the injection of gas into the abdominal cavity is poorly tolerated, blood clotting disorders and extreme obesity.
Sometimes the decision is made already during the operation: if the anatomy does not allow working safely, the surgeon switches to an open approach. This is not a complication, but a provided option, about which the patient is warned in advance.
What happens after discharge
In the first weeks, fractional meals, sufficient amounts of fluid and a gradual expansion of the motor regime are recommended. Heavy loads, saunas and swimming pools are avoided until healing.
Reasons to immediately consult a doctor include fever, increasing abdominal pain, redness and discharge from punctures, nausea and vomiting, retention of stool and gas.
