Understanding the challenges of robotic-assisted surgery adoption: Perspectives from stakeholders and the general population on human-interaction, built environment, and training

This study aims to explore adoption barriers from three aspects critical to facilitating robotic-assisted-surgery (RAS) adoption: the human-robot-interaction, built-environment, and training. Guidelines for research and design are identified from these perspectives. This study consisted of three phases: 1) surveys to RAS stakeholders and a crowd-sourcing survey; 2) stakeholder focus groups; and 3) a workshop with subject-matter experts to prioritize future research for RAS. Barriers from the human-robot-interaction perspective include hesitancy among clinicians to trust automation and physical discomfort during prolonged RAS. Barriers impeding communication and workflow disruptions were identified considering the built-environment. Training barriers were exemplified by varying curriculums from formal (courses) to informal (peer training) for surgeons. Crowd-sourced survey results suggest socio-economic status plays a role in RAS perception. Design guidelines include: 1) improved ergonomics; 2) deliberate introduction of automation; 3) sufficient in-room storage for prospective operating rooms; and 4) the development of compact RAS devices for older/smaller rooms.

Management of complications after chest wall resection and reconstruction: a narrative review

Background and Objective

Chest wall resection and reconstruction procedures carry high postoperative morbidity. Therefore, successful outcomes necessitate prevention, prompt identification, and appropriate management of ensuing complications. This narrative review aims to provide a comprehensive overview of evidence-based strategies for managing complications following chest wall resection and reconstruction.

Methods

A literature search was conducted using the PubMed database for relevant English-language studies published since 1980.

Key Content and Findings

Complications following chest wall resection and reconstruction can be broadly classified into surgical site-related, respiratory, or other systemic complications. Surgical site and respiratory complications are the most common, with reported incidence rates of approximately 40% across some series. Predisposing factors for respiratory morbidity include greater numbers of resected ribs and concurrent pulmonary lobectomy. Definitive correlations between specific prosthetic materials and complications remain elusive. Management should be tailored to the type and severity of the complication, surgical variables, and patient factors. Specific approaches for managing common complications are discussed in detail. Emerging preventive approaches, such as minimally invasive surgical techniques, are also briefly highlighted to help guide future research.

Conclusions

An emphasis on anticipating and judiciously managing complications of chest wall resection and reconstruction, alongside a coordinated multidisciplinary approach, can optimize outcomes for patients undergoing this intrinsically complex surgery.

Circumferential esophageal leiomyoma: Management by combined robotic surgery and intraoperative endoscopy

Leiomyoma is the most common benign tumor of the esophagus. Open thoracotomy, the traditional approach adopted for the enucleation of the esophageal leiomyoma, over the years, has been gradually replaced by video-assisted thoracoscopic surgery. However, this minimally invasive approach has limitations, such as two-dimensional vision and reduced range of motion, which have recently been overcome by technical advantages of robot-assisted surgery. In the surgical management of circumferential esophageal leiomyoma, a combined use of robotic surgery and intraoperative endoscopy may be helpful to facilitate tumor enucleation and to prevent esophageal mucosal injury during the surgical procedure.

Robot-Assisted Surgery in Gynecology

The advancement of robotics-based procedures in the medical industry is the subject of this review article. The purpose of the surgical robot is to increase surgical abilities and address human shortcomings. The robot's success has been predicated on its ability to accurately and consistently repeat tasks. The following are a few objectives and quantifiable benefits of robotic technology improving surgical maneuverability and physical capabilities. In 2005, the FDA granted gynecological surgery approval for the Da Vinci surgical system. It has been quickly embraced and has already taken on a significant role at many of the locations where it is offered. It consists of a cart with robotic branches next to the patient and a high-resolution three-dimensional (3D) vision system. This study covers laparoscopy via robots in benign gynecological surgeries, myomectomy surgery, hysterectomies, endometriosis, tubal anastomosis, and sacrocolpopexy. The appropriate published studies were evaluated after a PubMed search was conducted. Additionally, procedures that may be used in the future are highlighted. In benign gynecological illness, most currently available research does not show a substantial benefit over traditional laparoscopic surgery. Robotics, however, does provide help in more complicated operations. Compared to laparoscopy, robotic assistance has a lower conversion rate to open procedures. Endo wrist movement of an automated machine during myomectomy surgery can perform proper and better suturing than traditional laparoscopy. The automated program is a noticeable improvement over laparoscopic surgery and, if price issues are resolved, can gain popularity among gynecological surgeons around the globe.

Enabling In-Bore MRI-Guided Biopsies With Force Feedback

Limited physical access to target organs of patients inside an MRI scanner is a major obstruction to real-time MRI-guided interventions. Traditional teleoperation technologies are incompatible with the MRI environment and although several solutions have been explored, a versatile system that provides high-fidelity haptic feedback and access deep inside the bore remains a challenge. We present a passive and nearly frictionless MRI-compatible hydraulic teleoperator designed for in-bore liver biopsies. We describe the design components, characterize the system transparency, and evaluate the performance with a user study in a laboratory and a clinical setting. The results demonstrate % difference between input and output forces during realistic manipulation. A user study with participants conducting mock needle biopsy tasks indicates that a remote operator performs equally well when using the device as when holding a biopsy needle directly in hand. Additionally, MRI compatibility tests show no reduction in signal-to-noise ratio in the presence of the device.

[Minimally invasive thoracoscopic and robot-assisted lobectomy]

OBJECTIVE

To compare the early outcomes of video-assisted and robot-assisted lobectomy.

MATERIAL AND METHODS

There were 74 robot-assisted lung resections for the period 2017-2018. Sixty-six patients underwent lobectomy and 8 - segmentectomy. Patients were divided into 2 groups to compare thoracoscopic procedures. The main group consisted of 66 patients after robot-assisted lobectomy. The control group included 247 patients after video-assisted lobectomy. Mean age of patients was 60.5 years (range 35-70). There 72% men and 28% women.

CONCLUSION

Both thoracoscopic procedures are characterized by high efficiency and safety. However, certain disadvantages are peculiar to both methods.

Real-Time Fluorescence Imaging in Thoracic Surgery

Near-infrared (NIR) fluorescence imaging provides a safe and cost-efficient method for immediate data acquisition and visualization of tissues, with technical advantages including minimal autofluorescence, reduced photon absorption, and low scattering in tissue. In this review, we introduce recent advances in NIR fluorescence imaging systems for thoracic surgery that improve the identification of vital tissues and facilitate the resection of tumorous tissues. When coupled with appropriate NIR fluorophores, NIR fluorescence imaging may transform current intraoperative thoracic surgery methods by enhancing the precision of surgical procedures and augmenting postoperative outcomes through improvements in diagnostic accuracy and reductions in the remission rate.

Training in robotic thoracic surgery-the European way

The increasing demand for robot-assisted thoracic surgery (RATS) in Europe requires a structured and standardized training module. Until now, Intuitive Surgical Inc. (Sunnyvale, CA, USA) has delivered the only available robotic surgery platform. Although the training program that is organized by Intuitive is divided in an initial and an advanced course, the success of the training depends on many external factors. Until now the training focused on experienced thoracic surgeons. The aim of this article is to offer a stepwise training module, which can be adopted by experienced open (thoracotomy) surgeons or video-assisted thoracic (VATS) surgeons but is primarily meant for thoracic surgery fellows and residents, as it is our sincere opinion that we should focus on training for this type of surgery as early in their careers as possible. In order to maintain surgical technique and minimize the chance of complications, on-going training and certification of the surgeons and the team is deemed necessary.

Latest technology in minimally invasive thoracic surgery

From the introduction of video-assisted thoracoscopic surgery (VATS) in the 1990s, to performing major lung resections using a uniportal VATS approach, technology has paved the way for the development of minimally invasive thoracic surgery. Natural orifice access to achieve a 'no port' approach, is also on the rise, with advancements in bronchoscopic techniques for diagnosis and therapy, as well as development of soft robotics to achieve desired flexibility, dexterity and stability in future platforms, which may involve in vivo deployment to bring the surgeon totally inside the body. Development of haptic feedback in robotic platforms to enhance the surgical experience is also a major goal, with vibrotactile and mechanical feedback generation, to replicate the traditional touch. In addition, the aid of technology in the form of procedural guidance mechanisms, like augmented reality, will further improve the safety and accuracy of future operations.

Morgagni hernia repair in adult obese patient by hybrid robotic thoracic surgery

Morgagni hernia is a relatively uncommon congenital diaphragmatic hernia in which abdominal contents protrude into the chest through the foramen of Morgagni. It usually occurs on the right side of the chest but may occur on the left side or in the midline. In adults, it commonly presents with non-specific symptoms such as dyspnea, cough, gastroesophageal reflux disease and other. Surgical repair should be always performed to prevent the risk of hernia incarceration. Transthoracic approach has been proposed especially in cases with indeterminate, anterior pericardial masses. We believe that in adult obese patients with Morgagni hernia and voluminous hernial sac containing only omentum, the transthoracic approach can represent a valid alternative to transabdominal approach. The use of hybrid robotic thoracic surgery can be strongly recommended because it allows, through robotic instruments, to perform delicate surgical maneuvers in difficult to reach anatomical areas and, with the final extension of a port-site incision, to remove voluminous specimens from the thoracic cavity, avoiding the chest wall discomfort that follow the thoracotomy access.
