Abstract
The Children's Hospital Working Group has developed an ethical framework to guide patient care and research for prenatally diagnosed severe renal anomalies. It identifies ethical challenges in communication, timing of decisions and scarce resources. Key elements include shared decision-making, establishing a trusting relationship, and managing disagreement. The ethical framework will be used to develop a clinical pathway that operationalizes the key values of trust, honesty, transparency, beneficence, nonmaleficence, respecting parental authority, professional integrity, and justice.

Abstract
BACKGROUND It is common for doctors to engage in clinical innovation-i.e. to use novel interventions that differ from standard practice, and that have not yet been shown to be safe or effective according to the usual standards of evidence-based medicine-in the belief that this will benefit their patients. Clinical innovation is currently poorly defined and lacks cohesive oversight mechanisms. METHODS A systematic narrative review, with the aim of identifying areas of similarity and divergence in innovation ethics frameworks developed across different medical specialties. RESULTS 47 articles were included in the review. Few ethical issues raised by the ethics frameworks appear to be unique to distinct areas of practice. While variations exist in the oversight mechanisms suggested, these are again not specific to areas of practice, but rather reflect either cautious or more permissive attitudes towards clinical innovation. CONCLUSIONS There is considerable overlap amongst ethics frameworks developed for use in diverse areas of practice. This reflects a tendency to treat innovative interventions in each area of practice as "exceptional" and a failure to develop "higher order" frameworks such as those that have been developed for research. Those involved in the oversight of clinical innovation need to aim for a balance between exceptionalism and harmonisation.

Editorial Commentary: Adoption of New Medical Technology Requires Replication of Consistent Results Across Multiple Studies: Biologic Injections for Knee Osteoarthritis. Arthroscopy 2023; 39:79-81. [PMID: 36543426 DOI: 10.1016/j.arthro.2022.08.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 08/05/2022] [Indexed: 12/23/2022]
Abstract
Determining when to adopt new treatment methods in a clinical practice is a challenging undertaking. Uncertain outcomes of emerging technology can undermine the impartial assessment of risk and benefit. "Optimism bias" can lead to premature adoption of technology. An additional risk is that influential colleagues often persuade clinicians to innovate. "Replicability" or obtaining consistent results across studies aimed at answering the same scientific question must be a goal prior to adoption of innovative devices and treatments. The ability to replicate the results by a separate research group in a similar population with different input data is critical to gaining acceptance from providers without a personal stake in the development of technology.

Abstract
BACKGROUND The initial phases of robotic surgical skills acquisition are associated with poor technical performance, such as low knot-tensile strength (KTS). Transcranial direct-current stimulation (tDCS) can improve force and accuracy in motor tasks but research in surgery is limited to open and laparoscopic tasks in students. More recently, robotic surgery has gained traction and is now the most common approach for certain procedures (e.g. prostatectomy). Early-phase robotic suturing performance is dependent on prefrontal cortex (PFC) activation, and this study aimed to determine whether performance can be improved with prefrontal tDCS. METHODS Fifteen surgical residents were randomized to either active then sham tDCS or sham then active tDCS, in two counterbalanced sessions in a double-blind crossover study. Within each session, participants performed a robotic suturing task repeated in three blocks: pre-, intra- and post-tDCS. During the intra-tDCS block, participants were randomized to either active tDCS (2 mA for 15 min) to the PFC or sham tDCS. Primary outcome measures of technical quality included KTS and error scores. RESULTS Significantly faster completion times were observed longitudinally, regardless of active (p < 0.001) or sham stimulation (p < 0.001). KTS was greater following active compared to sham stimulation (median: active = 44.35 N vs. sham = 27.12 N, p < 0.001). A significant reduction in error scores from "pre-" to "post-" (p = 0.029) were only observed in the active group. CONCLUSION tDCS could reduce error and enhance KTS during robotic suturing and warrants further exploration as an adjunct to robotic surgical training.

Abstract
BACKGROUND The world is in the midst of the "digital" revolution characterized by the ascendency of computerization, information systems and artificial intelligence with an emphasis on innovation and creativity. This revolution has affected current medical practice and promises to significantly impact it in the future. This requires physician's understanding and participation in adopting such technology. This study aimed to explore the role technology plays in the future career plans of medical students. METHODS A questionnaire examining selection criteria for medical specialty choice, criteria for choosing a post-residency job and demographic data was completed by a convenience sample of 5th-year Israeli medical students. RESULTS Two-hundred forty-two students (51 % men) completed the questionnaire, an 84 % response rate. Only a third (35 %) rated the specialty selection criterion "provides mechanical/ technological challenges" as important, while only 7% considered as important that a specialty requires skills in computer science. Few students were interested in post-residency positions requiring much technological knowledge (25 %) and requiring much skill with computerized information systems (13 %). Male students were significantly more interested than females in such positions and these students more often reported that they were considering careers in surgery and its subspecialties. This surgical bent was confirmed by the 42 % of students interested in post-residency positions that include time in the operating room having more interest in positions requiring much technological knowledge than the students not interested in operating room time. CONCLUSIONS This preliminary study demonstrated that as a group the students' expressed relatively little interest in medical specialties and post-residency positions involving technological challenges and knowledge of information (computer) science. Yet, the sub-group interested in the surgical specialties had such interests. These findings were perplexing since the students belong to Generations Y and Z who are steeped in the use of smartphones and social media. Therefore, we failed to support our hypothesis that Generation Y and Z students would be attracted to specialties and positions that provide them with technological challenges. Furthermore, medical educators need to explore this apparent lack of interest in technology in order to insure that the future physician workforce is ready to face future "digital" challenges.

Three-dimensional Printing in Plastic Surgery: Current Applications, Future Directions, and Ethical Implications. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2021; 9:e3465. [PMID: 33968548 PMCID: PMC8099403 DOI: 10.1097/gox.0000000000003465] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2020] [Accepted: 01/13/2021] [Indexed: 11/26/2022]
Abstract
Background Three-dimensional printing (3DP) is a rapidly advancing tool that has revolutionized plastic surgery. With ongoing research and development of new technology, surgeons can use 3DP for surgical planning, medical education, biological implants, and more. This literature review aims to summarize the currently published literature on 3DP's impact on plastic surgery. Methods A literature review was performed using Pubmed and MEDLINE from 2016 to 2020 by 2 independent authors. Keywords used for literature search included 3-dimensional (3D), three-dimensional printing (3DP), printing, plastic, surgery, applications, prostheses, implants, medical education, bioprinting, and preoperative planning. All studies from the database queries were eligible for inclusion. Studies not in English, not pertaining to plastic surgery and 3DP, or focused on animal data were excluded. Results In total, 373 articles were identified. Sixteen articles satisfied all inclusion and exclusion criteria, and were further analyzed by the authors. Most studies were either retrospective cohort studies, case reports, or case series and with 1 study being prospective in design. Conclusions 3DP has consistently shown to be useful in the field of plastic surgery with improvements on multiple aspects, including the delivery of safe, effective methods of treating patients while improving patient satisfaction. Although the current technology may limit the ability of true bioprinting, research has shown safe and effective ways to incorporate biological material into the 3D printed scaffolds or implants. With an overwhelmingly positive outlook on 3DP and potential for more applications with updated technology, 3DP shall remain as an effective tool for the field of plastic surgery.

Abstract
AIM Essential Skills in the Management of Surgical Cases (ESMSC Marathon Course™) Integrated Generation 4 (iG4) is the first reported multifaceted undergraduate surgical course aiming to provide holistic surgical teaching. In this prospective observational study, we explored students' views on the iG4 curriculum, and identified how it can potentially address modern challenges in surgical training. MATERIAL AND METHODS Medical students were invited to apply to the course online and were screened against pre-defined criteria. A multi-national structured questionnaire incorporating five domains related to the course curriculum and our dedicated research network, was designed and distributed to participants after successful completion of the course. RESULTS Forty-one students from European and Asian medical schools completed the course and filled in the survey. The median overall evaluation score of the course was 4.73 out of 5 (interquartile range=4.21-4.72) and all students found that iG4 served the vision of holistic surgical education. ESMSC had a positive motivational effect towards following a career in surgery (p=0.012) and 92.7% of students declared that it should be an essential part of a future medical school curriculum. There was no statistically significant difference (p>0.05) in results between participants of different countries of study, year of studies or age group. CONCLUSION The ESMSC Marathon Course™ is perceived as a unique course model, with an established educational value and a positive motivational effect towards surgery. It might potentially be implemented in future medical school curricula as an essential element of undergraduate surgical education. The iG4 curriculum has opened a new exciting horizon of opportunities for advancing undergraduate holistic surgical education.

Abstract
BACKGROUND Minimal data exist on clinical decision-making in VAD implantation in pediatrics. This study aims to identify areas of consensus/variability among pediatric VAD physicians in determining eligibility and factors that guide decision-making. METHODS An 88-item survey with clinical vignettes was sent to 132 pediatric HT cardiologists and surgeons at 37 centers. Summary statistics are presented for the variables assessed. RESULTS Total respondents were 65 (72% cardiologists, 28% surgeons) whose centers implanted 1-5 (34%), 6-10 (40%), or >10 (26%) VADs in the past year. Consensus varied by patients' age, diagnosis, and Pedimacs profile. Highest agreement to offer VAD (97%) was a mechanically ventilated teenager with dilated cardiomyopathy. Patients stable on inotropes were less likely offered VAD (11%-25%). SV infant with Pedimacs profile 2 had the most varied responses: 37% offered VAD; estimated survival ranged from 15% to 90%. Variables considered for VAD eligibility included mild developmental delays (100% offered VAD), moderate-severe behavioral concerns (46%), cancer in remission >2 years (100%), active malignancy with good prognosis (68%) or uncertain prognosis (36%), and BMI >35 (74%) or <15 (69%). Most respondents (91%) would consider destination therapy VADs in pediatrics, though not currently feasible at 1/3 of centers. Factors with greatest influence on decision-making included HT candidacy, families' goals of care, and risks of complications. CONCLUSIONS Significant variation exists among pediatric VAD physicians when determining VAD eligibility and estimating survival, which can lead to differences in access to emerging technologies across institutions. Further work is needed to understand and mitigate these differences.

Abstract
Improving surgical interventions is key to improving outcomes. Ensuring the safe and transparent translation of such improvements is essential. Evaluation and governance initiatives, including the IDEAL framework and the Macquarie Surgical Innovation Identification Tool have begun to address this. Yet without a definition of innovation that allows non-surgeons to identify when it is occurring, these initiatives are of limited value. A definition seems elusive, so we undertook a conceptual study of surgical innovation. This indicated common conceptual areas in discussions of (surgical) innovation, that we categorised alliteratively under the themes of "purpose" (about drivers of innovation), "place" (about contexts of innovation), "process" (about differentiating innovation), "product" (about tangible and intangible results of innovation) and "person" (about personal factors and viewpoint). These conceptual areas are used in varying-sometimes contradictory-ways in different discussions. Highlighting these conceptual areas of surgical innovation may be useful in clarifying what should be reported in registries of innovation. However our wider conclusion was that the term "innovation" carries too much conceptual baggage to inform normative inquiry about surgical practice. Instead, we propose elimination of the term "innovation" from serious discourse aimed at evaluation and regulation of surgery. In our view researchers, philosophers and policy-makers should consider what it is about surgical activity that needs attention and develop robust definitions to identify these areas: for our own focus on transparency and safety, this means finding criteria that can objectively identify certain risk profiles during the development of surgery.

Abstract
BACKGROUND Sometimes the development of new surgical procedures takes place during patient treatment in clinical practice but can result in undesirable outcomes and social concerns. This study aims to reveal how university hospitals in Japan supervise the implementation of new surgical procedures and what difficulties they confront. METHODS Self-administered questionnaire surveys were conducted, targeting all university-affiliated hospitals in Japan. RESULTS It was found that most university hospitals in Japan supervised new surgical procedures internally, but they considered it difficult and burdensome to review and monitor them, both technically and practically, owing to several factors. CONCLUSION It is advisable to set up more effective and efficient organizational collaborations and implement standard processes of supervision, in both domestic and international clinical settings.

Abstract
Purpose. To investigate the knowledge, attitude, and practice of surgeons toward introducing novel surgical techniques in Egypt, Palestine, and Vietnam. Summary Background Data. Despite the recent advances in modern surgical care and its role in advancing the quality and the length of lives, surgery in the developing world has stagnated or even regressed. Methods. A survey was undertaken among the surgeons in 9 hospitals belonging to the 3 countries. Questions were categorized into knowledge, attitude, and practice questions. Meta-analyses were performed to estimate the event rate and compare between knowledge and practice, senior and junior surgeons. Results. A total of 244 responses, with a response rate of 79.7%, were included in the analysis. Regarding knowledge and attitude, the results were satisfactory except that only 55.8% of surgeons appraised their level of education and 43.3% wanted to earn money from the novel procedure. There was a significant difference between knowledge and practice regarding getting informed consent from the patients (P = .024), discussing the novelty of the procedure (P < .001), discussing the alternative procedures (P < .001), discussing the surgeons' experience and level of skills (P < .001), discussing the risk of the new procedure (P < .001), and monitoring the outcomes after the new procedure (P < .001). Conclusions. Most surgeons have sufficient knowledge and are motivated regarding adopting novel surgical techniques in order to provide the best care for the patients. However, there was a gap between knowledge and practice. Training programs and evidence-based guidelines regarding the introduction of novel surgical techniques are needed to overcome these challenges.

Abstract
This article investigates qualitatively the value profile of the da Vinci® surgical robot after almost two decades of extensive clinical use and research. We aimed to understand whether the swiftly growing body of published studies on robotic prostate surgery can now, that is, beyond an early stage, guide decisions on the acquisition, procurement, and public provision of this innovation. We explored both published studies and the perspectives of diverse stakeholders in the Netherlands. Both arenas represent conflicting, often polarised arguments on the (added) value of da Vinci surgery. What was unclear a decade ago due to lack of evidence is now unclear because of controversies about evidence. The article outlines controversial value issues and indicates the unlikelihood that awaiting more research - amid the mantra "further studies are needed" - will resolve the controversy. The study underscores multi-stakeholder deliberation to resolve controversies regarding the value of advanced medical innovations.

Defining Innovation in Neurosurgery: Results from an International Survey. World Neurosurg 2018; 114:e1038-e1048. [PMID: 29604357 DOI: 10.1016/j.wneu.2018.03.142] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2017] [Revised: 03/20/2018] [Accepted: 03/20/2018] [Indexed: 11/21/2022]
Abstract
BACKGROUND Innovation is a part of the daily practice of neurosurgery. However, a clear definition of what constitutes innovation is lacking and opinions vary from continent to continent, from hospital to hospital, and from surgeon to surgeon. METHODS In this study, we distributed an online survey to neurosurgeons from multiple countries to investigate what neurosurgeons consider innovative, by gathering opinions on several hypothetical cases. The anonymous survey consisted of 52 questions and took approximately 10 minutes to complete. RESULTS A total of 355 neurosurgeons across all continents excluding Antarctica completed the survey. Neurosurgeons achieved consensus (>75%) in considering specific cases to be innovative, including laser resection of meningioma, focused ultrasonography for tumor, oncolytic virus, deep brain stimulation for addiction, and photodynamic therapy for tumor. Although the new dura substitute case was not considered innovative, there was consensus among neurosurgeons indicating that institutional review board approval was still necessary to maintain ethical standards. Furthermore, although 90% of neurosurgeons considered an oncolytic virus for glioblastoma multiforme to be innovative, only 78% believed that institutional review board approval was necessary before treatment. CONCLUSIONS Our results indicate that innovation is a heterogeneous concept among neurosurgeons that necessitates standardization to ensure appropriate patient safety without stifling progress. We discuss both the ethical drawbacks of not having a clear definition of innovation and the challenges in achieving a unified understanding of innovation in neurosurgery and offer suggestions for uniting the field.

Abstract
ECMO has proven to be a life-saving intervention for a variety of disease entities with a high rate of survival in the neonatal population. However, ECMO requires clinical teams to engage in many ethical considerations. Even with ongoing improvements in technology and expertise, some patients will not survive a course of ECMO. An unsuccessful course of ECMO can be difficult to accept and cause a great deal of angst. These questions can result in real conflict both within the care team, and between the care team and the family. Herein we explore a range of ethical considerations that may be encountered when caring for a patient on ECMO, with a particular focus on those courses where it appears likely that the patient will not survive. We then consider how a palliative care approach may provide a tool set to help engage the team and family in confronting the difficult decision to discontinue ECMO.

Abstract
INTRODUCTION Worldwide, more than 20 million patients undergo groin hernia repair annually. The many different approaches, treatment indications and a significant array of techniques for groin hernia repair warrant guidelines to standardize care, minimize complications, and improve results. The main goal of these guidelines is to improve patient outcomes, specifically to decrease recurrence rates and reduce chronic pain, the most frequent problems following groin hernia repair. They have been endorsed by all five continental hernia societies, the International Endo Hernia Society and the European Association for Endoscopic Surgery. METHODS An expert group of international surgeons (the HerniaSurge Group) and one anesthesiologist pain expert was formed. The group consisted of members from all continents with specific experience in hernia-related research. Care was taken to include surgeons who perform different types of repair and had preferably performed research on groin hernia surgery. During the Group's first meeting, evidence-based medicine (EBM) training occurred and 166 key questions (KQ) were formulated. EBM rules were followed in complete literature searches (including a complete search by The Dutch Cochrane database) to January 1, 2015 and to July 1, 2015 for level 1 publications. The articles were scored by teams of two or three according to Oxford, SIGN and Grade methodologies. During five 2-day meetings, results were discussed with the working group members leading to 136 statements and 88 recommendations. Recommendations were graded as "strong" (recommendations) or "weak" (suggestions) and by consensus in some cases upgraded. In the Results and summary section below, the term "should" refers to a recommendation. The AGREE II instrument was used to validate the guidelines. An external review was performed by three international experts. They recommended the guidelines with high scores. The risk factors for inguinal hernia (IH) include: family history, previous contra-lateral hernia, male gender, age, abnormal collagen metabolism, prostatectomy, and low body mass index. Peri-operative risk factors for recurrence include poor surgical techniques, low surgical volumes, surgical inexperience and local anesthesia. These should be considered when treating IH patients. IH diagnosis can be confirmed by physical examination alone in the vast majority of patients with appropriate signs and symptoms. Rarely, ultrasound is necessary. Less commonly still, a dynamic MRI or CT scan or herniography may be needed. The EHS classification system is suggested to stratify IH patients for tailored treatment, research and audit. Symptomatic groin hernias should be treated surgically. Asymptomatic or minimally symptomatic male IH patients may be managed with "watchful waiting" since their risk of hernia-related emergencies is low. The majority of these individuals will eventually require surgery; therefore, surgical risks and the watchful waiting strategy should be discussed with patients. Surgical treatment should be tailored to the surgeon's expertise, patient- and hernia-related characteristics and local/national resources. Furthermore, patient health-related, life style and social factors should all influence the shared decision-making process leading up to hernia management. Mesh repair is recommended as first choice, either by an open procedure or a laparo-endoscopic repair technique. One standard repair technique for all groin hernias does not exist. It is recommended that surgeons/surgical services provide both anterior and posterior approach options. Lichtenstein and laparo-endoscopic repair are best evaluated. Many other techniques need further evaluation. Provided that resources and expertise are available, laparo-endoscopic techniques have faster recovery times, lower chronic pain risk and are cost effective. There is discussion concerning laparo-endoscopic management of potential bilateral hernias (occult hernia issue). After patient consent, during TAPP, the contra-lateral side should be inspected. This is not suggested during unilateral TEP repair. After appropriate discussions with patients concerning results tissue repair (first choice is the Shouldice technique) can be offered. Day surgery is recommended for the majority of groin hernia repair provided aftercare is organized. Surgeons should be aware of the intrinsic characteristics of the meshes they use. Use of so-called low-weight mesh may have slight short-term benefits like reduced postoperative pain and shorter convalescence, but are not associated with better longer-term outcomes like recurrence and chronic pain. Mesh selection on weight alone is not recommended. The incidence of erosion seems higher with plug versus flat mesh. It is suggested not to use plug repair techniques. The use of other implants to replace the standard flat mesh in the Lichtenstein technique is currently not recommended. In almost all cases, mesh fixation in TEP is unnecessary. In both TEP and TAPP it is recommended to fix mesh in M3 hernias (large medial) to reduce recurrence risk. Antibiotic prophylaxis in average-risk patients in low-risk environments is not recommended in open surgery. In laparo-endoscopic repair it is never recommended. Local anesthesia in open repair has many advantages, and its use is recommended provided the surgeon is experienced in this technique. General anesthesia is suggested over regional in patients aged 65 and older as it might be associated with fewer complications like myocardial infarction, pneumonia and thromboembolism. Perioperative field blocks and/or subfascial/subcutaneous infiltrations are recommended in all cases of open repair. Patients are recommended to resume normal activities without restrictions as soon as they feel comfortable. Provided expertise is available, it is suggested that women with groin hernias undergo laparo-endoscopic repair in order to decrease the risk of chronic pain and avoid missing a femoral hernia. Watchful waiting is suggested in pregnant women as groin swelling most often consists of self-limited round ligament varicosities. Timely mesh repair by a laparo-endoscopic approach is suggested for femoral hernias provided expertise is available. All complications of groin hernia management are discussed in an extensive chapter on the topic. Overall, the incidence of clinically significant chronic pain is in the 10-12% range, decreasing over time. Debilitating chronic pain affecting normal daily activities or work ranges from 0.5 to 6%. Chronic postoperative inguinal pain (CPIP) is defined as bothersome moderate pain impacting daily activities lasting at least 3 months postoperatively and decreasing over time. CPIP risk factors include: young age, female gender, high preoperative pain, early high postoperative pain, recurrent hernia and open repair. For CPIP the focus should be on nerve recognition in open surgery and, in selected cases, prophylactic pragmatic nerve resection (planned resection is not suggested). It is suggested that CPIP management be performed by multi-disciplinary teams. It is also suggested that CPIP be managed by a combination of pharmacological and interventional measures and, if this is unsuccessful, followed by, in selected cases (triple) neurectomy and (in selected cases) mesh removal. For recurrent hernia after anterior repair, posterior repair is recommended. If recurrence occurs after a posterior repair, an anterior repair is recommended. After a failed anterior and posterior approach, management by a specialist hernia surgeon is recommended. Risk factors for hernia incarceration/strangulation include: female gender, femoral hernia and a history of hospitalization related to groin hernia. It is suggested that treatment of emergencies be tailored according to patient- and hernia-related factors, local expertise and resources. Learning curves vary between different techniques. Probably about 100 supervised laparo-endoscopic repairs are needed to achieve the same results as open mesh surgery like Lichtenstein. It is suggested that case load per surgeon is more important than center volume. It is recommended that minimum requirements be developed to certify individuals as expert hernia surgeon. The same is true for the designation "Hernia Center". From a cost-effectiveness perspective, day-case laparoscopic IH repair with minimal use of disposables is recommended. The development and implementation of national groin hernia registries in every country (or region, in the case of small country populations) is suggested. They should include patient follow-up data and account for local healthcare structures. A dissemination and implementation plan of the guidelines will be developed by global (HerniaSurge), regional (international societies) and local (national chapters) initiatives through internet websites, social media and smartphone apps. An overarching plan to improve access to safe IH surgery in low-resource settings (LRSs) is needed. It is suggested that this plan contains simple guidelines and a sustainability strategy, independent of international aid. It is suggested that in LRSs the focus be on performing high-volume Lichtenstein repair under local anesthesia using low-cost mesh. Three chapters discuss future research, guidelines for general practitioners and guidelines for patients. CONCLUSIONS The HerniaSurge Group has developed these extensive and inclusive guidelines for the management of adult groin hernia patients. It is hoped that they will lead to better outcomes for groin hernia patients wherever they live. More knowledge, better training, national audit and specialization in groin hernia management will standardize care for these patients, lead to more effective and efficient healthcare and provide direction for future research.

Abstract
BACKGROUND Single-site laparoscopy is increasingly popular for straightforward operations like appendectomy. Due to limited triangulation and maneuverability, single-site cholecystectomy is riskier and more difficult. Robotics offer to make it easier and safer. METHODS Twenty children and adolescents underwent robotic-assisted single-site cholecystectomy at a large academic children's hospital. Patients were not randomized; patients were offered the option of robotic-assisted single-site (SSR) or standard four-incision laparoscopic (LAP) cholecystectomy. Demographics and perioperative details were compared with those of a comparable cohort who underwent LAP during the same period. RESULTS The two groups were similar in physical characteristics and indications for operation. The robotic operations took longer but both groups received similar PRN doses of parenteral opiates. Patients in the SSR group were all discharged on the first postoperative day. There were no major complications in either group but a slightly higher incidence of minor wound complications in the SSR group. CONCLUSION Robotic-assisted single-site cholecystectomy appears to be a safe alternative to standard laparoscopy with a similar postoperative pain profile, short postoperative lengths of stay, and, for some, a superior cosmetic result. Nevertheless, it comes with longer set-up and operative times, a higher incidence of minor wound complications, an unknown but possibly higher risk of incisional hernia, and higher costs.

Abstract
Robotic surgery has undergone exponential growth since the last two decades. Employment of new technologies in surgery creates many ethical challenges concerning the advantages and disadvantages different from conventional surgery, ensuring safety of the new technology, giving permission to surgeons for using new technology, the way of informing patients before undergoing a new technology or technique, and the responsibilities of surgeons, firms and hospitals to the patients etc. In this review, robotic surgery was discussed from malpractice perspective.

Abstract
Surgical innovation typically falls under the purview of neither conventional clinical ethics nor research ethics. Due to a lack of oversight for surgical innovation-combined with a potential for significant risk-a wide range of arguments has been advanced in the literature to support or undermine various oversight mechanisms. To scrutinize the argumentation surrounding oversight options, we conducted a systematic review of published arguments. We found that the arguments are typically grounded in common sense and speculation instead of evidence. Presently, the justification or superiority for any single oversight mechanism for surgical innovation cannot be established convincingly. We suggest ways to improve the argument-based literature and discuss the value of systematic reviews of arguments and reasons.

Abstract
Robotic surgery (RS) technology has undergone rapid growth in the surgical field since its approval. In clinical practice, failure of robotic procedures mainly results from a surgeon's inability or to a device malfunction. We reviewed the literature to estimate the impact of this second circumstance in RS and its consequent legal implications. According to data from the literature, device malfunction is rare. We believe it is necessary to complement surgical training with a technical understanding of RS devices.
