BACKGROUND: Robotic technology is an important tool in surgical innovation, with robots increasingly being used in the clinical setting. Robots can be used to enhance accuracy, perform remote actions, or to automate tasks. One such surgical task is suturing, a repetitive, fundamental component of surgery that can be tedious and time consuming. Suturing is a promising automation target because of its ubiquity, repetitive nature, and defined constraints. This systematic review examines research to date on autonomous suturing.
METHODS: A systematic review of the literature focused on autonomous suturing was conducted in accordance with PRISMA guidelines.
RESULTS: 6850 articles were identified by searching PubMed, Embase, Compendex, and Inspec. Duplicates and non-English articles were removed. 4389 articles were screened and 4305 were excluded. Of the 84 remaining, 43 articles did not meet criteria, leaving 41 articles for final review. Among these, 34 (81%) were published after 2014. 31 (76%) were published in an engineering journal9 in a robotics journal, and 1 in a medical journal. The great majority of articles (33, 80%) did not have a specific clinical specialty focus, whereas 6 (15%) were focused on applications in MIS/laparoscopic surgery and 2 (5%) on applications in ophthalmology. Several suturing subtasks were identified, including knot tying, suture passing/needle insertion, needle passing, needle and suture grasping, needle tracking/kinesthesia, suture thread detection, suture needle shape production, instrument assignment, and suture accuracy. 14 articles were considered multi-component because they referred to several previously mentioned subtasks.
CONCLUSIONS: In this systematic review exploring research to date on autonomous suturing, 41 articles demonstrated significant progress in robotic suturing. This summary revealed significant heterogeneity of work, with authors focused on different aspects of suturing and a multitude of engineering problems. The review demonstrates increasing academic and commercial interest in surgical automation, with significant technological advances toward feasibility.

Robotic innovations in breast surgery have ushered in a new era of precision, safety, and patient-centred care. This comprehensive review explores the multifaceted realm of robotic breast surgery, from preoperative planning to postoperative outcomes, learning curves for surgeons, and the implications for healthcare policies. We examine the ethical considerations, cost-effectiveness, and future directions, including integrating artificial intelligence and telesurgery. Key findings reveal that robotic systems provide improved surgical precision, reduced complications, and enhanced patient satisfaction. Ethical concerns encompass informed consent, resource allocation, and equitable access. The future of breast surgery lies in continued research and development, ensuring that robotics becomes a standard of care accessible to all patients. This technology is reshaping breast surgery and offering new possibilities for minimally invasive, patient-centred care, ultimately redefining the standards of care in this critical field of medicine.

Surgery is constantly evolving with the assistance of rapidly developing novel technology. Eye-tracking devices provide opportunities to monitor the acquisition of surgical skills, gain insight into performance, and enhance surgical practice. The aim of this review was to consolidate the available evidence for the use of eye-tracking in the surgical disciplines.
A systematic literature review was conducted in accordance with PRISMA guidelines. A search of OVID Medline, EMBASE, Cochrane library, Scopus, and Science Direct was conducted January 2000 until December 2022. Studies involving eye-tracking in surgical training, assessment and technical innovation were included in the review. Non-surgical procedures, animal studies, and studies not involving surgical participants were excluded from the review.
The search returned a total of 12 054 articles, 80 of which were included in the final analysis and review. Seventeen studies involved eye-tracking in surgical training, 48 surgical assessment, and 20 were focussing on technical aspects of this technology. Twenty-six different eye-tracking devices were used in the included studies. Metrics such as the number of fixations, duration of fixations, dwell time, and cognitive workload were able to differentiate between novice and expert performance. Eight studies demonstrated the effectiveness of gaze-training for improving surgical skill.
The current literature shows a broad range of utility for a variety of eye-tracking devices in surgery. There remains a lack of standardization for metric parameters and gaze analysis techniques. Further research is required to validate its use to establish reliability and create uniform practices.

The expansion of robotic surgery has led to developments in robotic-assisted breast reconstruction techniques. Specifically, robotic flap harvest is being evaluated to help maximize operative reliability and reduce donor site morbidity without compromising flap success. Many publications are feasibility studies or technical descriptions; few cohort analyses exist. This systematic review aims to characterize trends in robotic autologous breast reconstruction and provide a summative analysis of their results. A systematic review was conducted using PubMed, Medline, Scopus, and Web of Science to evaluate robot use in breast reconstruction. Studies dated from 2006 to 2022 were identified and analyzed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Full-text, peer-reviewed, English-language, and human subject studies were included. Non-breast reconstruction articles, commentary, expert opinion, editor\'s letter, and duplicate studies were excluded. A total of 17 full-text articles were analyzed. The two robotic breast procedures identified were the deep inferior epigastric perforator (DIEP) and the latissimus dorsi (LD) flap. Results showed comparable complication rates and increased operative times compared to NSQIP data on their corresponding open techniques. Additional findings reported in studies included patient reported outcomes, incision lengths, and downward trends in operative time with consecutive procedures. The available data in the literature confirms that robotic surgery is a promising alternative to traditional open methods of breast reconstruction following mastectomy.

BACKGROUND: Postoperative atrial fibrillation (POAF) is one of the most common complications following cardiac surgery and is associated with increased morbidity. Intraoperative topical amiodarone application on epicardial tissue has been shown to reduce systemic concentrations while maintaining therapeutic myocardial concentrations, thereby, lowering the risk of extracardiac adverse effects associated with oral and intravenous amiodarone therapy. However, the efficacy and safety of topical amiodarone in preventing POAF is unclear.
OBJECTIVE: This study summarizes the clinical studies to-date that have investigated the efficacy and safety of topical amiodarone administration in preventing POAF following cardiac surgery.
METHODS: A database search was conducted using Medline, Embase, and Cochrane Library to identify relevant studies. Abstracts were screened and data were extracted from relevant full-text articles that met the inclusion and exclusion criteria.
RESULTS: The search returned four studies with variable findings on the effect of topical amiodarone therapy on the incidence of POAF, cardiac effects, extracardiac effects, and hospital length of stay.
CONCLUSIONS: Prophylactic topical application of amiodarone may be effective and safe for preventing post-operative new-onset atrial fibrillation. Further investigation is required to evaluate the efficacy and safety of topical amiodadrone therapy before it can be widely integrated into current practice.

The embracing of new technology and surgical innovation has been one of the hallmarks of cardiothoracic surgery. The adoption of video-assisted thoracoscopic surgery was the paradigm-changing perspective shift that has enabled an entire culture of minimally invasive cardiothoracic surgery. From this foundation robotically assisted thoracic surgery has developed into mainstream practice. The aim of this review is to recount the technological and academic milestones of the past as well as describe future technological innovations that will shape the future of thoracic robotic surgery.

OBJECTIVE: The main objective of this review was to map how decision analytic models are used in surgical innovation (in which research phase, with what aim) and to understand how challenges related to the assessment of surgical interventions are incorporated.
METHODS: We systematically searched PubMed, Embase, and the Cochrane Library for studies published in 2018. We included original articles using a decision analytic model to compare surgical strategies. We included modeling studies of surgical innovations. General, innovation, and modeling characteristics were extracted, as were outcomes, recommendations, and handling of challenges related to the assessment of surgical interventions (learning curve, incremental innovation, dynamic pricing, quality variation, organizational impact).
RESULTS: We included 46 studies. The number of studies increased with each research phase, from 4% (n = 2) in the preclinical phase to 40% (n = 20) in phase 3 studies. Eighty-one studies were excluded because they investigated established surgical procedures, indicating that modeling is predominantly applied after the innovation process. Regardless of the research stage, the aim to determine cost-effectiveness was most frequently identified (n = 40, 87%), whereas exploratory aims (eg, exploring when a strategy becomes cost-effective) were less common (n = 9, 20%). Most challenges related to the assessment of surgical interventions were rarely incorporated in models (eg, learning curve [n = 1, 2%], organizational impact [n = 2, 4%], and incremental innovation [n = 1, 2%]), except for dynamic pricing (n = 10, 22%) and quality variation (n = 6, 13%).
CONCLUSIONS: In surgical innovation, modeling is predominantly used in later research stages to assess cost-effectiveness. The exploratory use of modeling seems still largely overlooked in surgery; therefore, the opportunity to inform research and development may not be optimally used.

Efficient adoption of clinically effective novel surgical innovations has great potential benefits for patients. Factors affecting the adoption of surgical innovation are not well understood and proposed models of adoption do not accurately correlate with historical evidence. This protocol is for a systematic review that aims to identify the qualitative evidence relating to surgeon views regarding the adoption of novel surgical innovation into clinical practice.
A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance will be performed. Two independent reviewers will search the following databases: MEDLINE, Embase, Science Direct, Scopus, Web of Science and the Cochrane Library of Systematic Reviews. Inclusion criteria are studies which report on the views of surgeons who adopt a novel surgical innovation into clinical practice. Each article will be screened for inclusion and assessed according to a Critical Appraisal Skills Programme tool. Data will be synthesised and analysed according to thematic analysis. Given the anticipated yield of a small heterogeneous body of evidence meeting the eligibility criteria for the review, a narrative-based summary is planned.
This review does not require formal ethical approval as it does not involve direct patient contact or patient-identifiable data. The results of this review will be published in a peer-reviewed journal and presented at relevant conferences. The results will also inform an empirical qualitative study exploring surgeon and other stakeholder views regarding the introduction of novel surgical technology and procedures into clinical practice.

Transoral robotic surgery (TORS) has been adopted in some parts of the world as an innovative approach to the resection of oropharyngeal tumours. The development, details and outcomes of early-to-later phase evaluation of this technique and the quality of evidence to support its adoption into practice have hitherto not been summarised. The aim of this review is to identify and summarise the early and later phase studies of, and evidence for, TORS and to understand how early phase studies report intervention development, governance procedures and selection and reporting of outcomes to optimise methods for using the Idea, Development, Exploration, Assessment, Long-term follow-up (IDEAL) framework for surgical innovation that informs evidence-based practice. The protocol has been written in line with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols checklist.
Electronic searches in OVID SP versions of Medline and EMBASE, the Cochrane Central Register of Controlled Trials and the Cochrane Database of Systematic Reviews from the start of indexing to 30 April 2017 will identify studies reporting TORS. At least two independent researchers will identify studies for inclusion. Two researchers will extract data from each paper. Studies will be categorised into IDEAL stages of study design from \'pre-IDEAL\' to randomised controlled trials (stage 3). Data will be collected about the (1) novel intervention and criteria for modification, (2) governance arrangements and patient information provision, (3) outcome domains selected and reported and (4) quality of study design, conduct and reporting. Descriptive statistics and a narrative synthesis will be presented.
The results of this systematic review will be presented at relevant conferences. The methods will be used to inform future reviews exploring other novel surgical innovations. The findings will be published in a peer-reviewed journal. This study does not require ethical approval.

Most aspects of surgical therapy for stress urinary incontinence (SUI) after radical prostatectomy (RP) are under debate or poorly studied. A systematic review was conducted and a literature search was carried out through PubMed database for articles on the surgical procedures for male SUI after RP published from Jan 2010 to Nov 2016. The efficacy results (pad count, 24 h pad test), complications, and quality of life (QoL) were reported. The included studies were categorized in accordance with the IDEAL framework of surgical innovation. Only Stage 0-2 IDEAL studies were revealed by systematic review of the literature. Randomized and long-term trials are missing. The current evidence on male SUI therapy is low. IDEAL-conform evaluation of new therapies should be applied in the future.
