 Introduction

Surgery has always been at the forefront of medical advancements, constantly evolving to save lives and improve the quality of care. From the crude instruments of ancient times to the highly sophisticated tools of today, surgical techniques have come a long way. In recent years, the marriage of technology and surgery has given birth to a new era, where precision and minimally invasive procedures dominate. Robotics, in particular, has revolutionized the way surgeries are performed, bringing a level of accuracy and control that was once unimaginable.

 

 The Evolution of Surgical Techniques

 Historical Overview

The history of surgery is as old as human civilization. Ancient practices, often crude and dangerous, laid the foundation for what would become one of the most critical fields in medicine.

 Ancient Practices

Early surgical practices were rudimentary, with little understanding of anatomy or hygiene. Ancient Egyptians, Greeks, and Romans performed surgeries with basic tools and a lot of guesswork. Despite the risks, these early surgeons set the stage for future advancements.

 The Renaissance Period in Surgery

The Renaissance brought a renewed interest in science and medicine, leading to significant advancements in surgical techniques. Surgeons like Andreas Vesalius began to challenge old misconceptions, emphasizing the importance of anatomy and dissection in understanding the human body.

20thCentury Breakthroughs

The 20th century saw rapid advancements in surgery, with the development of anesthesia, antiseptics, and more sophisticated surgical tools. These innovations dramatically reduced the risks associated with surgery and opened the door to more complex procedures.

 

 Introduction of Minimally Invasive Surgery (MIS)

 What is MIS?

Minimally Invasive Surgery (MIS) is a surgical technique that involves smaller incisions, less trauma to the body, and faster recovery times compared to traditional surgery. MIS has transformed the surgical landscape, offering patients and surgeons numerous benefits.

Minimally invasive surgery (MIS) has evolved since the early 1900s, when George Kelling performed the first laparoscopic surgery in vivo.  Although Kelling and other surgeons successfully tested it on patients, widespread adoption was slow. Potential improvements in the field were not considered due to fear of complications and worst-case outcomes. This fear is further exacerbated by the increasing incidence rates that have accompanied the widespread adoption of laparoscopic techniques.  In the last century, the rise of new technologies forced change. A 1962 study discussed the application of television to endoscopic techniques, and further advances in resolution and miniaturization showed that laparoscopic surgery held promise.  However, it was not until the late 1970s that the technology was finally adopted. Kamran Nezhat began using video cameras in his surgeries, and laparoscopic surgery began to be taken more seriously, although he said in his inaugural address that he was battling criticism from his colleagues.

 Benefits of Minimally Invasive Techniques

Minimally invasive techniques offer several advantages, including reduced pain, shorter hospital stays, and quicker recovery. Patients who undergo MIS often experience less scarring and a lower risk of complications, making it an attractive option for many surgical procedures.

Key Procedures in MIS

Key procedures in MIS include laparoscopic surgery, arthroscopy, and endoscopic surgery. These techniques are used in various fields, including gynecology, orthopedics, and gastroenterology, providing patients with safer and more effective treatment options.

Robotic Surgery Techniques to Improve Traditional Laparoscopy

The ability to perform minimally invasive surgery is so important in modern medicine that laparoscopic instruments and techniques are constantly improving. Progression from open surgery to minimally invasive surgery over the years has ultimately led to the use of robotic devices that use a separate console to assist or completely replace the patient's surgery. Although robotic surgery is highly regarded for its surgical outcomes, certain circumstances limit its use, such as Cost-effectiveness or space limitations. This review aimed to conduct a survey of the literature and discuss the trends.

Current Status of Laparoscopic Surgery

The MIS's performance is no longer justifiable today. The timing of open, laparoscopic, and robotic surgery varies depending on several factors. The operation (cholecystectomy, hysterectomy, etc.), the severity of the indication (disease progression, low risk/high risk), and the surgical expertise all influence the technique used. The surgical strategy might have to be altered due to intraoperative complications. B. converting from laparoscopic to open surgery for severe adhesions or opting for a different approach for intricate anatomical variations.

The instruments or tools utilized during laparoscopic surgery are another consideration. Every kind of surgery requires a certain set of tools, but some surgeries require specialized tools. Trocars are used to gain access to the abdominal cavity by puncturing the musculature and fascia of the abdominal wall with the sharp edge, allowing for other instruments to pass through a canal at the core. They can be disposable or reusable, with disposable trocars described frequently as being of higher quality but generally less cost-effective. Many different techniques are used for laparoscopic entry. All laparoscopic surgery techniques require the use of an illuminated scope or laparoscope. These are Open or Hasson entry, in which the trocar is inserted before insufflation of the abdomen, and closed or Veress needle entry, in which insufflation is performed before trocar insertion, are the two fundamental techniques.

 The Role of Robotics in Surgery

 The Birth of Robotic Surgery

Robotic surgery emerged in the late 20th century as a groundbreaking advancement in the medical field. The da Vinci Surgical System, introduced in the early 2000s, was one of the first robotic systems to gain widespread use. It allowed surgeons to perform complex procedures with greater precision and control than ever before.

The da Vinci Surgical System

The da Vinci Surgical System is a robotic platform that enables surgeons to perform minimally invasive surgery with enhanced dexterity and visualization. It consists of a console where the surgeon sits, controlling robotic arms that hold and manipulate surgical instruments. This system has been a game-changer in surgeries like prostatectomies, hysterectomies, and cardiac procedures.

The da Vinci Surgical System from Intuitive Surgical, Inc. is currently the most widely used robotic surgery system. It uses a master/slave console to let the surgeon work remotely from the surgical field. The system has impressed the medical community and is still used for more and more surgeries.

The da Vinci Surgical System

Due to its ability to provide a three-dimensional view of the surgical field at the master console, the da Vinci is also utilized in training settings as a virtual reality (VR) surgical simulator. Kiely et al. demonstrated how da Vinci was used in skills simulation to facilitate a smoother transition for trainees, particularly in suturing. After being introduced to Europe in 1997, the da Vinci robotic system was used for the first time in a 2000 surgery in Brussels, Belgium. In a 2001 study, operating times and preferred trocar and slave arm positioning were discussed as well as the clinical feasibility of the da Vinci performed 146 surgeries with 11 types of interventions. The study acknowledged that system design and protocols both need to be improved, but it praised da Vinci for its ability to reduce surgeon tremors and improve ergonomics.

In a study conducted just one year after its introduction, one of the first notable benefits of the da Vinci system was that it improved ergonomic complications seen in traditional laparoscopic surgery, as surgeons no longer needed to use instruments and hold themselves much more still.

 How Robotics Enhance Precision

Robotic systems provide surgeons with unparalleled precision. The robotic arms can make tiny, precise movements that would be difficult or impossible for human hands. This precision is precious in delicate surgeries, where even the smallest mistake can have significant consequences.

 

 Case Studies of Robotic-Assisted Surgeries

Numerous case studies have demonstrated the effectiveness of robotic-assisted surgeries. For example, robotic prostatectomies have shown lower rates of complications and faster recovery times compared to traditional open surgery. For Example, Laparoscopic prostatectomy was initially praised for its minimally invasive nature, but it was difficult to perform and continued to evolve even before the widespread use of robotic systems. Stolzenburg et al. and Esposito et al. 2003 discussed a new extraperitoneal approach to radical prostatectomy to address complications encountered with the traditional transperitoneal approach. Although the 2003 study was performed using traditional laparoscopic techniques, the use of the robotic arm was stated to be particularly important to improve ergonomics and avoid hazards. The need for an additional assistant. The article by Lee et al. also discussed the use of only one assistant in robot-assisted laparoscopic radical prostatectomy, which differs from the traditional use of two assistants in previous procedures. A study by Kaufman et al. from 2006 introduced the idea of ​​utilizing defined postoperative management for robotic-assisted laparoscopic prostatectomy to improve postoperative outcomes after open radical prostatectomy and initiated a dialogue to further improve standards after the introduction of the Da Vinci system. Management changes related to nutrition, analgesia, and drainage management, and these changes correlated with reduced complications and readmissions after open prostatectomy.

Similarly, robotic-assisted Transoral Surgeries have led to better patient outcomes and shorter hospital stays. Hatten et al. retrospectively reviewed several cases requiring oropharyngeal reconstruction using transoral robotic-assisted surgery (TORS). This was necessary due to the difficulty in accessing the surgical field with traditional laparoscopic surgery. In 2002, successful gastroesophageal reflux repair was reported using the da Vinci. Although equipped with multiple ports, in 2015 the da Vinci was evaluated for transoral use in the pediatric airway of a cadaveric model, but success was more limited due to the limited surgical scope. An alternative to TORS, transoral endoscopic ultrasound surgery, has been used in the oropharynx. This method combines traditional laparoscopic techniques with an ultrasonic scalpel to coagulate tissue with lower heat, thereby reducing tissue damage. The technique has been described as similar to microscopic laser surgery. However, the use of an endoscope has made it possible to perform this technique without incising the body. Smart et al. discussed the use of the da Vinci robotic system in pediatric retropharyngeal flap surgery, which was successful in a preclinical model.
