Robot-Assisted Minimally Invasive Breast Surgery: Recent Evidence with Comparative Clinical Outcomes

In recent times, robot-assisted surgery has been prominently gaining pace to minimize overall postsurgical complications with minimal traumatization, due to technical advancements in telerobotics and ergonomics. The aim of this review is to explore the efficiency of robot-assisted systems for executing breast surgeries, including microsurgeries, direct-to-implant breast reconstruction, deep inferior epigastric perforators-based surgery, latissimus dorsi breast reconstruction, and nipple-sparing mastectomy. Robot-assisted surgery systems are efficient due to 3D-based visualization, dexterity, and range of motion while executing breast surgery. The review describes the comparative efficiency of robot-assisted surgery in relation to conventional or open surgery, in terms of clinical outcomes, morbidity rates, and overall postsurgical complication rates. Potential cost-effective barriers and technical skills were also delineated as the major limitations associated with these systems in the clinical sector. Furthermore, instrument articulation of robot-assisted surgical systems (for example, da Vinci systems) can enable high accuracy and precision surgery due to its promising ability to mitigate tremors at the time of surgery, and shortened learning curve, making it more beneficial than other open surgery procedures.

Robotic-Assisted Peripheral Nerve Surgery: A Systematic Review

BACKGROUND

 Robotic-assisted techniques are a tremendous revolution in modern surgery, and the advantages and indications were well discussed in different specialties. However, the use of robotic technique in plastic and reconstructive surgery is still very limited, especially in the field of peripheral nerve reconstruction. This study aims to identify current clinical applications for peripheral nerve reconstruction, and to evaluate the advantages and disadvantages to establish potential uses in the future.

METHODS

 A review was conducted in the literatures from PubMed focusing on currently published robotic peripheral nerve intervention techniques. Eligible studies included related animal model, cadaveric and human studies. Reviews on robotic microsurgical technique unrelated to peripheral nerve intervention and non-English articles were excluded. The differences of wound assessment and nerve management between robotic-assisted and conventional approach were compared.

RESULTS

 Total 19 studies including preclinical experimental researches and clinical reports were listed and classified into brachial plexus reconstruction, peripheral nerve tumors management, peripheral nerve decompression or repair, peripheral nerve harvesting, and sympathetic trunk reconstruction. There were three animal studies, four cadaveric studies, eight clinical series, and four studies demonstrating clinical, animal, or cadaveric studies simultaneously. In total 53 clinical cases, only 20 (37.7%) cases were successfully approached with minimal invasive and intervened robotically; 17 (32.1%) cases underwent conventional approach and the nerves were intervened robotically; 12 (22.6%) cases converted to open approach but still intervened the nerve by robot; and 4 (7.5%) cases failed to approach robotically and converted to open surgery entirely.

CONCLUSION

 Robotic-assisted surgery is still in the early stage in peripheral nerve surgery. We believe the use of the robotic system in this field will develop to become popular in the future, especially in the fields that need cooperation with other specialties to provide the solutions for challenging circumstances.

Minimally invasive robotic breast reconstruction surgery

The rising popularity of robotic surgery has enabled surgeons to continue to expand the uses of robotic surgery. Robotic surgery offers minimally invasive approaches coupled with tremor elimination, up to seven degrees of freedom, ergonomic positioning, 3D magnified vision and improved resolution. We describe robotic surgery techniques for nipple-sparing mastectomies, latissimus dorsi muscle flap harvest, deep inferior epigastric perforator (DIEP) flap pedicle harvest, and robotic microsurgical anastomoses. By using a robotic system the surgeon is able to offer not only a minimally invasive approach to the patient but the surgeon's ability can be improved upon as well. This improved ability is best characterized in the robotic supermicrosurgical anastomosis where even the faintest surgeon's tremor is exploited. However, within the robotic system tremor is eliminated. We are now able to offer patients a completely minimally invasive approach to ablative breast surgery and breast reconstruction. A patient could have a robotic nipple-sparing mastectomy, followed by a robotic DIEP reconstruction with a robotic microsurgical anastomosis. The patient could even have robotic lymphovenous bypass to address lymphedema that could have arisen after an axillary dissection. A completely robotic surgical approach maximizes both utilization of the robotic system and patient benefit. By using robotic techniques in flap harvest the morbidity of traditional open surgeries is minimized and the use of robotic anastomoses expands the limits of human precision.

Current Limitations of Surgical Robotics in Reconstructive Plastic Microsurgery

Surgical robots have the potential to provide surgeons with increased capabilities, such as removing physiologic tremor, scaling motion and increasing manual dexterity. Several surgical specialties have subsequently integrated robotic surgery into common clinical practice. Plastic and reconstructive microsurgical procedures have not yet  benefitted significantly from technical developments observed over the last two decades. Several studies have successfully demonstrated the feasibility of utilising surgical robots in plastic surgery procedures, yet limited work has been done to identify and analyse current barriers that have prevented wide-scale adaptation of surgical robots for microsurgery. Therefore, a systematic review using PubMed, MEDLINE, Embase and Web of Science databases was performed, in order to evaluate current state of surgical robotics within the field of reconstructive microsurgery and their limitations. Despite the theoretical potential of surgical robots, current commercially available robotic systems are suboptimal for plastic or reconstructive microsurgery. Absence of bespoke microsurgical instruments, increases in operating time, and high costs associated with robotic-assisted provide a barrier to using such systems effectively for reconstructive microsurgery. Consequently, surgical robots provide currently little overall advantage over conventional microsurgery. Nevertheless, if current barriers can be addressed and systems are specifically designed for microsurgery, surgical robots may have the potential of meaningful impact on clinical outcomes within  this surgical subspeciality.

A Systematic Review of the Role of Robotics in Plastic and Reconstructive Surgery-From Inception to the Future

Background

The use of robots in surgery has become commonplace in many specialties. In this systematic review, we report on the current uses of robotics in plastic and reconstructive surgery and looks to future roles for robotics in this arena.

Methods

A systematic literature search of Medline, EMBASE, and Scopus was performed using appropriate search terms in order to identify all applications of robot-assistance in plastic and reconstructive surgery. All articles were reviewed by two authors and a qualitative synthesis performed of those articles that met the inclusion criteria. The systematic review and results were conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta Analysis (PRISMA) guidelines.

Results

A total of 7,904 articles were identified for title and abstract review. Sixty-eight studies met the inclusion criteria. Robotic assistance in plastic and reconstructive surgery is still in its infancy, with areas such as trans-oral robotic surgery and microvascular procedures the dominant areas of interest currently. A number of benefits have been shown over conventional open surgery, such as improved access and greater dexterity; however, these must be balanced against disadvantages such as the lack of haptic feedback and cost implications.

Conclusion

The feasibility of robotic plastic surgery has been demonstrated in several specific indications. As technology, knowledge, and skills in this area improve, these techniques have the potential to contribute positively to patient and provider experience and outcomes.
