Robotic Surgery: From Science Fiction to Reality

MINIMALLY INVASIVE SURGERY has incorporated a technology known as COMPUTER-ASSISTED ROBOTIC SURGERY, which has made it possible to perform complex procedures with greater precision, flexibility, and control compared with conventional surgical techniques. These robots are not autonomous machines capable of performing an entire surgery on their own or solving a surgical problem through preprogrammed instructions. Instead, they complement and enhance the surgeon's abilities by translating human movements into highly stable, precise, and delicate robotic movements.

For this reason, the surgeon remains fully in control and ultimately responsible for the procedure. As with any surgical technique, the surgeon's training and experience play a fundamental role in determining the outcome.

Robotic procedures are becoming increasingly common, and scientific reports of failures involving robotic systems and their components remain very low. Robotic surgery may represent THE SURGERY OF THE FUTURE, as its usefulness has already been demonstrated in complex procedures such as esophagectomy, pancreatectomy, cardiovascular surgery, bariatric surgery, reconstructive urologic surgery, and oncologic surgery.

ADVANTAGES OF ROBOTIC SURGERY

• Three-dimensional visualization: The surgeon controls the camera directly, with images that can be magnified up to 20 times their normal size, allowing ORGANS AND ANATOMICAL STRUCTURES TO BE SEEN IN GREATER DETAIL.

• The surgeon operates from a computerized console while the robotic system precisely translates the surgeon's movements using articulated instruments. This improves cutting precision while FILTERING OUT NATURAL HAND TREMORS.

• The robotic system provides a greater range of motion than traditional laparoscopic surgery. Its articulated instruments allow MORE PRECISE MOVEMENTS and can scale the surgeon's hand movements, making delicate tasks such as suturing and knot tying easier to perform.

• Compared with traditional laparoscopic or open surgery, HOSPITAL STAYS MAY BE SHORTER, allowing patients to return to their normal activities sooner.

• It may reduce recovery time, improve functional outcomes, and result in LESS BLOOD LOSS. Small, precise incisions and highly controlled movements allow the surgeon to work accurately while minimizing unnecessary tissue damage.

• COSMETIC RESULTS CAN BE EXCELLENT. Incisions and scars are generally small, and those placed within the navel may be barely noticeable.

• Robotic instruments can REACH SMALL OR DIFFICULT-TO-ACCESS AREAS that would be challenging to reach with the human hand, facilitating procedures within confined surgical spaces.

• Through small incisions, surgeons can perform procedures that once required traditional open surgery.

• Certain complications may be reduced, including the risk of SURGICAL SITE INFECTIONS, due in part to the minimally invasive nature of the procedure and strict sterile surgical techniques.

DISADVANTAGES OF ROBOTIC SURGERY

• The surgeon has less direct tactile feedback from the tissues.

• The high cost of robotic technology remains one of the main barriers to its widespread adoption, particularly in countries with fewer healthcare resources. In addition to the cost of the equipment itself, each procedure involves additional expenses associated with operating the system.

• Many hospitals still do not have access to robotic surgical systems, although the technology is becoming increasingly available.

• Because preparing and positioning the robotic system may require additional time, some robotic procedures can take longer than laparoscopic or traditional surgery. This may increase the amount of time the patient remains under anesthesia.

USES OF ROBOTIC SURGERY

Although robotic technology cannot yet be used for every surgical procedure, it can provide valuable assistance to surgeons across a wide range of specialties and procedures, including:

• Coronary artery bypass surgery

• Removal of cancerous tissue located near sensitive structures such as blood vessels, nerves, or vital organs

• Cholecystectomy (gallbladder removal)

• Bariatric surgery (Gastric Bypass or Sleeve Gastrectomy)

• Esophageal surgery

• Pancreatic surgery

• Gastric surgery

• Colorectal surgery

• Arthroplasty (knee or hip replacement)

• Hysterectomy

• Kidney transplantation

• Tubal ligation

• Partial or total nephrectomy (kidney removal)

• Radical prostatectomy

• Among other procedures

ROBOTIC SURGERY IN BARIATRIC CARE

Surgical treatment is recognized as an effective long-term treatment option for severe obesity, and minimally invasive techniques have become a standard approach for many bariatric procedures. Robotic technology allows surgeons to perform complex bariatric procedures while applying many of the same surgical principles used in open and laparoscopic surgery, with enhanced visualization, dexterity, and precision.

Gastric bypass is one of the bariatric procedures that may particularly benefit from robotic assistance. The system's precision can facilitate delicate surgical steps, including suturing and the creation of gastrointestinal connections.

MEDICAL TRAINING IN ROBOTIC SURGERY

To perform robotic surgery, surgeons must complete specialized training and simulation exercises. This process requires dedicated training hours to become familiar with the technology, adapt surgical movements to the robotic system, and maintain appropriate standards of safety and quality. Surgeons must also receive training in the management of critical events and potential equipment failures. Understanding possible system errors and how to respond to them is an essential part of safely performing robotic procedures.

Although robotic surgery is still evolving, its introduction has represented a major advancement in modern surgery. It combines many of the benefits of minimally invasive techniques with enhanced visualization, dexterity, precision, and control.

As new technological advances continue to emerge, the robotic surgery systems available today may represent only the first step toward the surgery of tomorrow.
