Intraoperative teamwork and occupational stress during robot-assisted surgery: An observational study.

Robot-assisted surgery (RAS) differs from traditional OR set-ups in several ways such as operation of technology and obstructed team communication that potentially affect surgical staff's stress experiences. The current study investigates the effects of key intraoperative job demands and resources on mental workload and perceived stress in RAS. We focused on the role of intraoperative teamwork as a resource that potentially reduces occupational stress. Combining standardized expert observations in the OR with healthcare providers' self-reports, the study involved two types of robot-assisted, urological interventions. The sample consisted of 73 observed surgeries and included 242 post-operative surveys on perceived stress and mental workload from surgeons and surgical nurses. Multilevel regression analyses reveal differential effects for stress and workload. Importantly, whereas better surgical teamwork was associated with lower stress, it was unrelated to workload. Our findings provide a nuanced picture of occupational stress in RAS, particularly regarding the role of intraoperative teamwork.

Knowledge, attitude, and perception of robotic-assisted surgery among the general population in Saudi Arabia: a cross-sectional study.

Minimally invasive surgery (MIS) has revolutionized surgical practices, with robotic-assisted surgery (RAS) significantly advancing. However, the understanding and acceptance of RAS vary, impacting its widespread adoption. This study aims to assess Saudi Arabians' attitudes and comprehension of RAS, which is crucial for promoting its integration into surgical procedures. A cross-sectional study was conducted in various Saudi Arabian cities. A total of 1449 participants were included, while participants with cognitive issues were excluded. Demographic information, knowledge, technology experience, attitudes, and perceptions about RAS were collected using an online self-administered questionnaire. Data were analyzed using descriptive and inferential statistics. Of the participants, 51.1% demonstrated awareness of RAS, mainly through social media (36.9%). Factors influencing awareness included gender, education, income, occupation, computer literacy, and technology comfort. Gender disparities were evident in attitudes and perceptions toward RAS. Concerns about RAS included robot malfunction (62.0%), surgical errors (45.4%), and surgeon competency (44.7%). 36.4% of the participants believe RAS is faster, 29.9% believe RAS is less painful, and 25.3% believe RAS has fewer complications. Positive perceptions encompassed the belief that robot-using surgeons are more skilled (44.5%) and hospitals offering RAS are better (54.3%). Notably, 47.7% expressed willingness to consider RAS as a treatment option. The study underscores the significance of promoting awareness and informed decisions to ensure the successful integration of RAS in surgical practices. Addressing concerns and misconceptions and enhancing public comprehension are pivotal for facilitating informed decision-making and fostering RAS acceptance within Saudi Arabia's surgical landscape.

Utilizing deep neural networks and electroencephalogram for objective evaluation of surgeon's distraction during robot-assisted surgery.

OBJECTIVE: To develop an algorithm for objective evaluation of distraction of surgeons during robot-assisted surgery (RAS). MATERIALS AND METHODS: Electroencephalogram (EEG) of 22 medical students was recorded while performing five key tasks on the robotic surgical simulator: Instrument Control, Ball Placement, Spatial Control II, Fourth Arm Tissue Retraction, and Hands-on Surgical Training Tasks. All students completed the Surgery Task Load Index (SURG-TLX), which includes one domain for subjective assessment of distraction (scale: 1-20). Scores were divided into low (score 1-6, subjective label: 1), intermediate (score 7-12, subjective label: 2), and high distraction (score 13-20, subjective label: 3). These cut-off values were arbitrarily considered based on a verbal assessment of participants and experienced surgeons. A Deep Convolutional Neural Network (CNN) algorithm was trained utilizing EEG recordings from the medical students and used to classify their distraction levels. The accuracy of our method was determined by comparing the subjective distraction scores on SURG-TLX and the results from the proposed classification algorithm. Also, Pearson correlation was utilized to assess the relationship between performance scores (generated by the simulator) and distraction (Subjective assessment scores). RESULTS: The proposed end-to-end model classified distraction into low, intermediate, and high with 94%, 89%, and 95% accuracy, respectively. We found a significant negative correlation (r = -0.21; p = 0.003) between performance and SURG-TLX distraction scores. CONCLUSIONS: Herein we report, to our knowledge, the first objective method to assess and quantify distraction while performing robotic surgical tasks on the robotic simulator, which may improve patient safety. Validation in the clinical setting is required.

Building a predictive model of U.S. patient willingness to undergo robotic surgery.

Prior research regarding robotic surgery (RS) has largely focused on the engineering or medical aspects of these tools. A few studies have examined consumer opinions toward, or willingness to use, robotic surgeons; however, no study to date has examined what type of person would be willing to undergo RS. Across two studies, the current research fills this gap by building both a descriptive and predictive regression model used to predict what type of user would be willing to undergo RS. To build the descriptive model, 1324 potential patients were asked a series of questions about demographics, attitudes, opinions, and personalities. Results indicate that perceived value, familiarity, wariness of new technologies, fear of surgery, openness, anger, fear, and happiness are all significant predictors of willingness to undergo RS. A regression equation was developed and then used to predict scores in a second study with 1335 potential patients. The scores from both studies were compared for model fit. Several methods were used to validate the regression model, including correlational analyses, a t test, and calculation of the cross-validity coefficient. All three stringent tests showed strong model fit, explaining 62% of the variance in the model. These findings have both practical and theoretical values to the field and can be used to identify early adopters of this advanced medical technology.

Patient Satisfaction and Regret After Robot-assisted Radical Prostatectomy: A Decision Regret Analysis.

OBJECTIVE: To assess treatment satisfaction and decision regret post robot-assisted radical prostatectomy (RARP) and correlate these with clinical, demographic and quality of life indicators. Our study took place at a high-volume United Kingdom center and patients were assessed at a minimum of 18 months postsurgery. METHODS: Patients who underwent RARP between June 2011 and May 2016 were invited to participate through mailed questionnaires. A total of 207 patients formed our cohort. The questionnaires included European Organization for Research and Treatment of Cancer Quality of Life of Cancer patients 30 and PR25 modules, sexual health inventory in men and Likert decisional regret scale. A Decisional Regret Scale score of >15 was used to define an outcome of high decision regret. RESULTS: The mean patient age was 63 years and the mean duration of follow up was 36 months. Of the 106 responders, 51 (48%) were fully satisfied with the decision to undergo RARP and 32 (30%) recorded high regret. The mean Decisional Regret Scale score was 11.3. High decision regret associated with the length of time from RARP to questionnaire administration, higher prostate specific quality of life symptom scores and lower sexual and erectile function scores. CONCLUSION: Our study represents the first contemporary United Kingdom series assessing decision regret following the management of localised prostate cancer with RARP. Higher regret was seen in one third of patients and was associated with worse disease-specific quality of life, sexual and erectile function measures. To minimize regret, collaborative and detailed discussion should take place pre-operatively when counselling patients about RARP. The potential longevity and impact on quality of life of these side effects should be made clear.

Evaluation of quality of life, body image and surgical outcomes of robotic total laparoscopic hysterectomy and sentinel lymph node mapping in low-risk endometrial cancer patients - A Robotic Gyne Club study.

INTRODUCTION: The aims of the study were to evaluate quality of life, cosmetic results and surgical outcomes of robotic single-site and robotic multiport total laparoscopic hysterectomy with sentinel lymph node mapping in women treated for low-risk endometrial cancer. MATERIAL AND METHODS: The study is a prospective, multicenter, case-control study conducted at Ospedale Santa Chiara in Trento and Novara and Pavia University Hospitals. Seventy-six consecutive patients with a biopsy-confirmed diagnosis of low-risk endometrial cancer or atypical endometrial hyperplasia who between January 2017 and January 2019 had undergone robotic total laparoscopic hysterectomy and sentinel lymph node mapping were included. Data on surgical outcomes, quality of life and cosmetic results were prospectively collected and analyzed based on the surgical approach with robotic single-site vs robotic multiport assistance. Patients' clinical characteristics, intra-operative parameters, sentinel lymph node mapping results and postoperative findings were prospectively recorded. Clinical follow up was performed 4 weeks and 6 and 12 months after surgery. Fifty-one patients underwent a robotic multiport procedure and 25 patients a robotic single-site surgery. RESULTS: There was one significant difference between the two groups in terms of patient characteristics: mean body mass index (BMI) in the multiport group was 29 kg/m2 vs 24.8 kg/m2 in the single-site group (P value <.001). After univariate and multivariate analysis on intraoperative and postoperative findings, a shorter surgical time was observed in the single-site cohort than in the multiport group (148.7 vs 158.2 minutes, P value .0182). BMI also had a significant effect on surgical time (P = .022). No differences were seen in terms of sentinel lymph node detection: the bilateral detection rate was 96.1% for multiport (66.7% bilateral, 29.4% monolateral) and 96% for single-site (76% bilateral, 20% monolateral) procedures. No differences between the two approaches were identified with regard to postoperative complications, pain, cosmetic results or quality of life comparisons. CONCLUSIONS: For the treatment of low-risk endometrial cancer and atypical endometrial hyperplasia with total hysterectomy and sentinel lymph node mapping, the robotic single-port approach is comparable to the multiport procedure in terms of intraoperative and postoperative findings, and has an advantage in terms of shorter surgical times. Further studies are required to identify possible differences in quality of life and cosmetic results.

A cross-sectional study of current work ability after radical prostatectomy.

BACKGROUND: Work ability represents a person's subjective assessment of current ability to work compared to his lifetime best. Since many men with prostate cancer are retired, work ability represents a more relevant work measure than employment status. The primary aim was to examine the prevalence of men who had high versus moderate/poor current work ability compared to their lifetime best work ability at a mean of 3.0 years after robot-assisted laparoscopic prostatectomy. The secondary aim was to study variables associated with moderate/poor work ability at survey. METHODS: This is a questionnaire-based study of men who had robot-assisted laparoscopic prostatectomy at Oslo University Hospital, Radiumhospitalet between January 2005 and August 2010. Among them 777 responded (79%), 730 reported on current work ability, socio-demographic data, somatic and mental health, and typical adverse effects (the EPIC-26) after prostatectomy. High versus moderate/poor work ability was the primary outcome. Descriptive statistics and logistic regression analyses were applied. RESULTS: The mean age of the sample at survey was 65.5 years (SD 5.9). At survey 42% of the sample reported moderate/poor current work ability and 58% reported high work ability. In multivariable analysis older age at survey, low basic education, comorbidity, poor self-rated health, presence of depression and low EPIC-26 hormonal domain score remained significantly associated with moderate/poor work ability. CONCLUSIONS: Current work ability is a useful measure for the working capacity particularly of retired men. Socio-demographic, cancer-related, health, psychological and typical adverse effect variables were significantly associated with moderate/poor current work ability after robot-assisted laparoscopic prostatectomy, and several health and psychological variables are amenable to identification and treatment by health care providers.

Surgeon-Team Separation in Robotic Theaters: A Qualitative Observational and Interview Study.

BACKGROUND: The rapid uptake of robotic surgery has largely been driven by the improved technical aspects of minimally invasive surgery including improved ergonomics, wristed instruments, and 3-dimensional vision. However, little attention has been given to the effect of physical separation of the surgeon from the rest of the operating team. PURPOSE: The aim of this study was to examine in depth how this separation affected team dynamics and staff emotions. METHODS: Robotic procedures were observed in 2 tertiary hospitals, and laparoscopic/open procedures were added for comparison; field notes were taken instantaneously. One-to-one interviews with theater team members were audio recorded and transcribed verbatim. Qualitative analysis was conducted via grounded theory approach using NVIVO11. RESULTS: Twenty-nine participants (26 interviewed) were recruited to the study (11 females) and 134 (109 robotic) hours of observation were completed across gynecology, urology, and colorectal surgery.The following 3 main themes emerged with compounding factors identified: (a) communication challenge, (b) immersion versus distraction, and (c) emotional impact. Compounding factors included the following: individual and team experience, staffing levels, and the physical theater environment. CONCLUSIONS: Our emergent theory is that "surgeon-team separation in robotic theaters poses communication challenges which impacts on situational awareness and staff emotions." These can be ameliorated by staff training, increased experience, and team/procedure consistency.

Discovering the barriers to efficient robotic operating room turnover time: perceptions vs. reality.

Turnover time (TOT) has remained the subject of numerous research articles and operating room (OR) committee discussions. Inefficiencies associated with TOT are multiplied when complex technology, such as surgical robots, is involved. Using a human factors approach, this study investigated impediments to efficient robotic TOT and team members' perceptions surrounding this topic. Researchers observed 20 robotic turnovers over 2 months at a tertiary hospital. TOT, cleaning time, number of staff present, bed set-up time, instrument set-up time and any major delays were recorded. Additionally, 79 OR team members completed a questionnaire regarding perceptions of OR turnover. Average TOT was 72 min (s, 24 min). Overall, cleaning required the most time (average of 27.4 min, 37.96% of TOT), followed by instrument set-up (15.4 min, 21.34% of TOT) and RN retrieval of the patient from pre-op (12 min, 17.72% of TOT). OR team members estimated that turnovers require 60.36 min. Physicians believed the greatest contributor to TOT was "time to set up the OR", while OR staff rated "instrument availability" as the greatest issue, both of which were inaccurate. OR team members' perceptions of robotic TOT and contributing factors were different from reality based on observed contributors. Data demonstrated several areas of opportunity for process improvement. These data can be used to guide the implementation of targeted interventions to improve TOT efficiency.

Surgical decision-making for rectal prolapse: one size does not fit all.

BACKGROUND: Surgery remains the only known treatment option for rectal prolapse. Although over 100 abdominal and perineal procedures are available, there is no consensus as to which intervention is best suited for an individual. This retrospective cohort study describes the patient- and disease-related factors involved in making surgical recommendations around rectal prolapse in a single surgeon experience. METHODS: 91 consecutive patients ≥18 years old diagnosed with external and/or high-grade internal rectal prolapse were assessed and were prospectively entered into an IRB approved registry. Information on patient symptoms, comorbidities, exam findings, surgeon judgment, and patient preference was collected. Treatment recommendations (abdominal, perineal, or no operation) were analyzed and compared. RESULTS: Surgical intervention was recommended to 93% of patients. Of those, 66% were recommended robotic abdominal procedures: 75%, robotic ventral mesh rectopexies; 16%, resection rectopexies; and 9%, suture rectopexies. On univariate analysis, patients with older age, higher ASA scores, presence of cardiopulmonary morbidity, pain as a primary rectal prolapse symptom, rectal prolapse always descended, and surgeon concern for frailty and general anesthesia were associated with recommendations for perineal operations (p < 0.05 for all). However, on multivariate analysis, only age and concern over prolonged anesthesia remained correlated with a recommendation for perineal surgery. Of patients >80 years of age, 15% were recommended an abdominal approach. CONCLUSIONS: With multiple options available for the treatment of rectal prolapse, treatment recommendations remain surgeon-dependent and may be influenced by many factors. In our practice, robotic ventral mesh rectopexy was the most commonly recommended operation and was offered to carefully selected patients of advanced age. Although robotic surgery and ventral mesh rectopexy may not be accessible to all patients and surgeons, this represents a single surgeon's practice bias. This study reinforces the importance of perineal procedures for higher-risk individuals.

Impact of robotic assistance on mental workload and cognitive performance of surgical trainees performing a complex minimally invasive suturing task.

BACKGROUND: Few studies have investigated the potential impact of robotic assistance on cognitive ergonomics during advanced minimally invasive surgery. The purpose of this study was to assess the impact of robotic assistance on mental workload and downstream cognitive performance in surgical trainees. METHODS: Robot-naïve trainees from general surgery, urology and gynaecology, stratified by specialty and level of training, were randomised to either laparoscopic surgery (LS) or robotic-assisted laparoscopic surgery (RALS) and performed a time-limited, complex laparoscopic suturing task after watching a 5-min instructional video. The RALS group received an additional 5-min orientation to the robotic console. Subjective mental workload was measured using NASA Task Load Index. Concentration and executive cognitive function were assessed using Psychomotor Vigilance Task (PVT) and Wisconsin Card Sorting Test (WCST), respectively. A p value of 0.05 was considered significant. RESULTS: Sixteen senior residents (SR; ≥ PGY3) and 14 junior residents (JR; PGY1-2) completed the study. There was no difference in mental workload between LS and RALS. Within JR there was no difference in task completion time comparing LS versus RALS; however, LS was associated with impaired concentration post-task versus pre-task (PVT reaction time 306 versus 324 ms, p = 0.03), which was not observed for RALS. In contrast, amongst SR, RALS took significantly longer than LS (10.3 vs. 14.5 min, p = 0.02) and was associated with significantly worse performance on WCST (p < 0.01). CONCLUSIONS: Robotic assistance, in this setting, did not provide a technical performance advantage nor impact subjective mental workload with novice users regardless of level of surgery training. We observed a protective effect on cognitive performance offered by RALS to junior trainees with limited LS experience, yet a detrimental effect on senior trainees with greater LS ability and inadequate pre-study robotic training, suggesting that robotic consoles may be mentally taxing for robotic novices and consideration should be given to formal console training prior to initial clinical exposure.

Operative results and patient satisfaction after robotic pancreaticoduodenectomy.

BACKGROUND/OBJECTIVE: There are no reports available on patient satisfaction and quality-of-life after robotic pancreaticoduodenectomy (RPD). This study aimed to evaluate not only surgical outcomes but also patient satisfaction after RPD. METHODS: Prospectively collected data for RPD were analyzed for surgical outcomes. Questionnaires were sent to patients to assess patient satisfaction regarding RPD. RESULTS: The study included 105 patients who underwent RPD, with 44 (41.9%) patients presenting with associated surgical complications. There were no significant differences between the without and with complication groups in median console time (390 min. Vs. 373 min.), blood loss (100 mL vs. 100 mL), and harvested lymph node number (14 vs. 15). There was no surgical mortality in this study. Major complications ≥ Clavien-Dindo III occurred in 7.6% of the total 105 RPD patients. The most common complication was chyle leakage (18.1%), followed by postoperative pancreatic fistula (5.7%), intra-abdominal abscess (4.8%), delayed gastric emptying (3.8%), and post pancreatectomy hemorrhage (3.8%). Almost all of the patients responded to this RPD-related survey with "fair" to "excellent" grades for all items, except 1 (<1%) poor grade for operation service and 2 (1.9%) "not good" grades for diet tolerance. CONCLUSIONS: RPD is a feasible procedure with acceptable surgical outcomes. This patient survey with high patient satisfaction rates indicates that RPD provides acceptable satisfaction results, and the robotic approach for a major operation such as RPD has probably a higher priority than cost concerns. RPD could be recommended not only to surgeons but also to patients in terms of surgical outcomes and patient satisfaction.

Short-term quality of life after myomectomy for uterine fibroids from the COMPARE-UF Fibroid Registry.

BACKGROUND: Uterine fibroids may decrease quality of life in a significant proportion of affected women. Myomectomy offers a uterine-sparing treatment option for patients with uterine fibroids that can be performed abdominally, laparoscopically (with or without robotic assistance), and hysteroscopically. Quality of life information using validated measures for different myomectomy routes, especially hysteroscopic myomectomy, is limited. OBJECTIVE: To compare women's perception of their short-term health-related quality of life measures and reported time to return to usual activities and return to work for different routes of myomectomy. MATERIALS AND METHODS: Comparing Options for Management: Patient-centered Results for Uterine Fibroids (COMPARE-UF) is a prospective nationwide fibroid registry that enrolled premenopausal women seeking treatment for uterine fibroids at 8 clinical sites. For this analysis, we included women undergoing hysteroscopic, abdominal, or laparoscopic myomectomy who completed the postprocedure questionnaire scheduled between 6 and 12 weeks after surgery. Health-related quality of life outcomes, such as pain, anxiety, and return to usual activitie, were assessed for each route. The hysteroscopic myomectomy group had large differences in demographics, fibroid number, and uterine size compared to the other groups; thus, a direct comparison of quality of life measures was performed only for abdominal and laparoscopic approaches after propensity weighting. Propensity weighting was done using 24 variables that included demographics, quality of life baseline measures, and fibroid and uterine measurements. RESULTS: A total of 1206 women from 8 COMPARE-UF sites underwent myomectomy (338 hysteroscopic, 519 laparoscopic, and 349 abdominal). All women had substantial improvement in short-term health-related quality of life and symptom severity scores, which was not different among groups. Average symptom severity scores decreased about 30 points in each group. Return to usual activities averaged 0 days (interquartile range, 0-14 days) for hysteroscopic myomectomy, 21 days (interquartile range, 14-28 days) for laparoscopic myomectomy, and 28 days (interquartile range, 14-35 days) for abdominal myomectomy. After propensity adjustment, quality of life outcomes in the laparoscopic and abdominal myomectomy groups were similar except for more anxiety in the laparoscopic myomectomy group and slightly more pain in the abdominal myomectomy group. After propensity weighting, return to usual activities favored laparoscopic compared to abdominal procedures; median time was the same at 21 days, but the highest quartile of women in the abdominal group needed an additional week of recovery (interquartile range,14.0-28.0 for laparoscopic versus 14.0-35.0 for abdominal, P < .01). Time to return to work was also longer in the abdominal arm (median, 22 days; interquartile range, 14-40 days, versus median, 42; interquartile range, 27-56). CONCLUSION: Women who underwent myomectomy had substantial improvement in health-related quality of life, regardless of route of myomectomy. After propensity weighting, abdominal myomectomy was associated with a nearly 2-week longer time to return to work than laparoscopic myomectomy.

General surgery training in the era of robotic surgery: a qualitative analysis of perceptions from resident and attending surgeons.

BACKGROUND: The use of the surgical robot has increased annually since its introduction, especially in general surgery. Despite the tremendous increase in utilization, there are currently no validated curricula to train residents in robotic surgery, and the effects of robotic surgery on general surgery residency training are not well defined. In this study, we aim to explore the perceptions of resident and attending surgeons toward robotic surgery education in general surgery residency training. METHODS: We performed a qualitative thematic analysis of in-person, one-on-one, semi-structured interviews with general surgery residents and attending surgeons at a large academic health system. Convenient and purposeful sampling was performed in order to ensure diverse demographics, experiences, and opinions were represented. Data were analyzed continuously, and interviews were conducted until thematic saturation was reached, which occurred after 20 residents and seven attendings. RESULTS: All interviewees agreed that dual consoles are necessary to maximize the teaching potential of the robotic platform, and the importance of simulation and simulators in robotic surgery education is paramount. However, further work to ensure proper access to simulation resources for residents is necessary. While most recognize that bedside-assist skills are essential, most think its educational value plateaus quickly. Lastly, residents believe that earlier exposure to robotic surgery is necessary and that almost every case has a portion that is level-appropriate for residents to perform on the robot. CONCLUSIONS: As robotic surgery transitions from novelty to ubiquity, the importance of effective general surgery robotic surgery training during residency is paramount. Through in-depth interviews, this study provides examples of effective educational tools and techniques, highlights the importance of simulation, and explores opinions regarding the role of the resident in robotic surgery education. We hope the insights gained from this study can be used to develop and/or refine robotic surgery curricula.

Gender differences in understanding and acceptance of robot-assisted surgery.

Robot-assisted surgery has numerous patient benefits compared to open surgery including smaller incisions, lower risk of infection, less post-operative pain, shorter hospital stays and a quicker return to the workforce. As such, it has become the first-choice surgical modality for several surgical procedures with the most common being prostatectomy and hysterectomy. However, research has identified that the perceptions of robot-assisted surgery among surgical patients and medical staff often do not accurately reflect the real-world situation. This study aimed to understand male and female perceptions of robot-assisted surgery with the objective of identifying the factors that might inhibit or facilitate the acceptance of robotic surgery. Semi-structured interviews were undertaken with 25 men/women from diverse social/ethnic backgrounds. The interviews were transcribed and analysed using thematic analysis. The majority of female participants expressed concerns in relation to the safety and perception of new technology in surgery, whereas many male participants appeared to be unfazed by the notion of robotic surgery. There were clear differences in how males and females understood and conceptualised the robot-assisted surgical process. Whilst male participants tended to humanise the process, female participants saw it as de-humanising. There is still a discrepancy between the public perceptions of robotic surgery and the clinical reality perceived by healthcare professionals. The findings will educate medical staff and support the development of current informative techniques given to patients prior to surgery.

Anesthesia Professionals' Perspectives of Teamwork During Robotic-Assisted Surgery.

Robotic-assisted surgery (RAS) presents unique teamwork challenges for perioperative team members, including anesthesia professionals. The purpose of this study was to explore anesthesiologists' and nurse anesthetists' teamwork experiences during RAS using an exploratory qualitative study design involving individual semistructured interviews. Study participants expressed that teamwork during RAS is both positive and challenging, and the start-up phase is the most demanding phase of RAS in terms of teamwork. Anesthesia professionals believe that both technical and nontechnical skills are necessary to provide excellent patient care and maintain patient safety during RAS. Furthermore, they believe that a more concentrated focus on nontechnical skills than is traditional is an essential component of teamwork.

Hybrid Robotics for Endoscopic Skull Base Surgery: Preclinical Evaluation and Surgeon First Impression.

BACKGROUND: A robotic endoscope holder should theoretically provide various advantages in transnasal endoscopic skull base surgery, but only recently has a robotic system become commercially available. The objective of this study was to provide a preclinical evaluation of potential advantages and surgeon first impression of this robotic hybrid solution. METHODS: Thirty skull base surgeons, attending the Joint European Diploma of Endoscopic Skull Base Surgery 2018-2019 in Paris, France, were enrolled. A questionnaire, mainly concerning personal surgical experience and habits, was administered. The test phase consisted of 2 different dry-lab tasks, performed with and without EndoscopeRobot, according to randomization and on 2 different days. A modified NASA Task Load Index test was subsequently administered via e-mail to all participants. Completion times and modified Global Evaluative Assessment of Robotic Skills in Endoscopy scores of the videotaped tasks were recorded. RESULTS: Nineteen otorhinolaryngologic surgeons and 11 neurosurgeons, with different surgical habits and endoscopic experience, were enrolled. No one appeared unfavorable a priori to robotic endoscopic surgery. Although the robot did not provide an advantage in the simple grasping task 1, a trend toward better completion times and efficacy was evident in the bimanual task 2, when performed with the robot and bimanually. According to the modified NASA Task Load Index test, surgeons felt more successful with the robot in task 2, finding it less stressful and mentally demanding. CONCLUSIONS: Endoscopic skull base surgeons seem to view a hybrid robotic solution positively. EndoscopeRobot seems to provide a benefit to the single surgeon with experience in bimanual endoscopic surgery. Further preclinical and clinical evaluation of this technology is necessary.

Patient Perceptions of New Robotic Technologies in Clinical Restorative Dentistry.

Patient perception research has failed to focus on burgeoning technology within the dental field. Specifically, researchers have yet to focus on developing robotic technologies which are being utilized by dentists to help perform certain procedures with added precision and route mapping. The current study attempts to fill the gap created by a lack of intersection between dental technology research, consumer perceptions research, and automation research. The current research takes a two-study approach, with study 1 investigating if gender or price of the procedure affects willingness to undergo a robotic dental procedure. Study 2 further investigates this phenomenon, identifying ten separate types of dental procedures (ranging from minimally invasive to extremely invasive) to further understand consumer perceptions. Results indicate that females are less willing to undergo a robotic dental procedure, and that participants in general are more willing to undergo a procedure if it is half price than if it full price. Willingness is influenced by gender and the type of procedure being performed - participants were less willing to undergo invasive procedures such as gum surgery than noninvasive procedures such as teeth whitening. These results, and their theoretical and practical significance are discussed.

Factors Associated With Treatment Satisfaction After Robot-assisted Radical Prostatectomy.

BACKGROUND/AIM: To evaluate the chronological changes in health-related quality of life and treatment satisfaction after robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS: A total of 196 patients were included, and treatment satisfaction was evaluated using the Expanded Prostate Cancer Index Composite (EPIC) score before and at 1, 3, 6, and 12 months after RARP. RESULTS: At 12 months after RARP, 64.8% of patients were satisfied. On the contrary, 4.6% of patients were dissatisfied at 12 months after RARP. In a multivariate analysis, only urinary bother of EPIC was significantly associated with satisfaction at 12 months after RARP (p=0.025, odds ratio=1.029). CONCLUSION: Treatment satisfaction with RARP was generally acceptable from 1 to 12 months after surgery and did not change over time. Urinary bother was associated with satisfaction at 12 months after RARP. Compared with the objective 24-hour pad test, questionnaires answered subjectively were more associated with satisfaction.

Quality of life in patients who undergo conventional or robotic-assisted total laparoscopic hysterectomy: Protocol for a systematic review of randomized controlled trials.

BACKGROUND: Hysterectomy for benign gynecologic diseases, especially dysfunctional uterine bleeding, is one of the most common gynecologic interventions. The uterus can be removed using abdominal, vaginal, laparoscopic, or robotic-assisted laparoscopic hysterectomy. In a robotic-assisted procedure, the surgeon directs the robot while seated at a console in the operating room. This differs from laparoscopic hysterectomy because a "robot" performs the operation, while the surgeon watches a monitor. This systematic review will compare quality of life (QOL) in patients who undergo total robotic-assisted laparoscopic hysterectomy for benign indications and those who undergo conventional laparoscopic surgery. METHODS: We will perform a systematic review according to the Cochrane Methodology for randomized controlled trials. The review will include studies reporting use of QOL metrics to assess patients who undergo total hysterectomy for benign indications using robotic-assisted technique or conventional laparoscopic surgery. QOL will be the primary outcome and will be measured using validated instruments. An overall search strategy will be developed and adapted for Embase, MEDLINE, LILACS, and CENTRAL databases. Two reviewers will independently select the eligible studies, assess the risk of bias, and extract the data from included studies. Similar outcomes measured in at least 2 trials will be plotted in the meta-analysis using Review Manager 5.3. The quality of evidence will be determined using the GRADE approach. RESULTS: This systematic review is designed to provide high quality evidence on QOL in patients undergoing total hysterectomy for benign indications using either robotic-assisted or conventional laparoscopic surgery. CONCLUSION: It is expected that high-quality evidence on QOL can be used to guide decision-making by institutions and clinicians to improve health care; the evidence can also be used in future studies.
