Modeling the Adoption of 5760 Clinical Studies Into Practice Across 5 Surgical Specialties.

INTRODUCTION: No studies exist that explore the factors that influence the process of synthesizing new knowledge into perioperative standards of care and the operating room. We sought to model the adoption of clinical research into surgical practice and identify modifiable factors influencing the latency of this translation. METHODS: We created a data set comprised of all UpToDate articles between 2011 and 2020, sampled at 3-mo intervals, to explore how research is incorporated at the point-of-care (POC)-studying 5760 new references from 204 journals across five surgical specialties, compared to all uncited articles published during the same interval. UpToDate authors serve as specialty curators of the vast surgical literature, with an audience of more than a million clinicians in over 180 countries across 3200 institutions. Unlike society guidelines, UpToDate also provides the necessary granularity to quantify the time in bringing research to the bedside. Our main outcomes are citation rates and time-to-citation, split by specialty, journal, article type, and topics. We also model the influence of impact factor, geography, and funding and, finally, propose new impact indices to help with prioritizing surgical literature. RESULTS: We highlight variation in adoption of clinical research by specialty. We show, despite representing a lower quality of evidence, surgical case reports are one of the most cited article types. Furthermore, most clinical trials (94%-100%) in surgical journals are never incorporated into POC reference lists. While few, pragmatic trials were the most likely to be cited of any article type in any surgical specialty (40%). Journal impact factor did not correlate with time-to-citation or proportion of articles cited in three of five surgical specialties, suggesting differences in how specialties synthesize/value research from specialty journals. Our two metrics, the Clinical Relevancy and Immediacy Indices, were defined to capture this impact/relevance to surgical practice. Of the five surgical subspecialties, gynecology references were >5-fold more likely to get cited, had a larger fraction of higher quality evidence incorporated, and demonstrated more success with POC adoption of practice guidelines. We also quantified the cost of translating research to surgical practice per specialty and generated maps that highlight institutions successful in translating research to the POC. The higher expenditure of National Institutes of Health funding in gynecology may reflect the cost of higher quality research per citation. CONCLUSIONS: Understanding translational latency is the first step to exposing blocks that slow the adoption of research into everyday surgical practice and to understanding why increasing research funding has not yielded comparative gains in surgical outcomes. Our approach reveals new methods to monitoring the efficiency of research investments and evaluating the efficacy of policies influencing the translation of research to surgical practice.

Preoperative Depression Status and 5 Year Metabolic and Bariatric Surgery Outcomes in the PCORnet Bariatric Study Cohort.

OBJECTIVE: To examine whether depression status before metabolic and bariatric surgery (MBS) influenced 5-year weight loss, diabetes, and safety/utilization outcomes in the PCORnet Bariatric Study. SUMMARY OF BACKGROUND DATA: Research on the impact of depression on MBS outcomes is inconsistent with few large, long-term studies. METHODS: Data were extracted from 23 health systems on 36,871 patients who underwent sleeve gastrectomy (SG; n=16,158) or gastric bypass (RYGB; n=20,713) from 2005-2015. Patients with and without a depression diagnosis in the year before MBS were evaluated for % total weight loss (%TWL), diabetes outcomes, and postsurgical safety/utilization (reoperations, revisions, endoscopy, hospitalizations, mortality) at 1, 3, and 5 years after MBS. RESULTS: 27.1% of SG and 33.0% of RYGB patients had preoperative depression, and they had more medical and psychiatric comorbidities than those without depression. At 5 years of follow-up, those with depression, versus those without depression, had slightly less %TWL after RYGB, but not after SG (between group difference = 0.42%TWL, P = 0.04). However, patients with depression had slightly larger HbA1c improvements after RYGB but not after SG (between group difference = - 0.19, P = 0.04). Baseline depression did not moderate diabetes remission or relapse, reoperations, revision, or mortality across operations; however, baseline depression did moderate the risk of endoscopy and repeat hospitalization across RYGB versus SG. CONCLUSIONS: Patients with depression undergoing RYGB and SG had similar weight loss, diabetes, and safety/utilization outcomes to those without depression. The effects of depression were clinically small compared to the choice of operation.

Gamification of robotic simulation to train general surgery residents.

BACKGROUND: Gamification applies game design elements to non-game contexts in order to engage participation and increase learner motivation. Robotic surgery is gaining popularity in general surgery but requires specialized technical skills. We sought to determine whether gamification of robotic simulation training could increase robotic simulator utilization among general surgery residents. METHODS: General surgery residents were recruited and sent weekly progress on simulator performance including leaderboards for 4 weeks during the intervention periods. There were also two control periods setup in an ABAB study design. Usage time and mean scores were compared between the control periods and intervention periods. A post-study qualitative assessment interview using semi-structured interviews determined barriers and motivational components of simulator usage. RESULTS: Fifteen general surgery residents enrolled in the study (n = 15). Intervention increased total simulator usage time 9.7-fold from 153 to 1485 min. Total simulator days increased threefold from 9 to 27 days. Resident participation increased from 33 to 53%. Median average scores were higher during the intervention periods (58.8 and 81.9 vs 44.0). During the first intervention period, median individual-level simulator usage time increased 17 min (P = 0.03). However, there was no individual-level increase in median usage minutes or days during the second intervention period. Qualitative assessment determined barriers to be limited time due to clinical duties, and simulator availability while motivational factors included competitive factors such as leaderboards and gaming aspects. Potential improvements were increasing attending visibility of scores to increase recognition of progress by the residents and creating dedicated time for training. CONCLUSION: Gamification of robotic simulation training increased general surgery resident participation, usage time and scores. Impact was not durable. Instituting dedicated practice time and more attending engagement may increase trainee motivation and performance.

Decision regret up to 6 years after sleeve gastrectomy.

BACKGROUND: Sleeve gastrectomy (SG) is one of the most popular types of weight loss surgery today but is neither risk-free nor universally effective. We previously demonstrated that 5% of Roux-en-Y gastric bypass (RYGB) patients and up to 20% of gastric banding patients report overall regret 4 years after surgery. This study explores patients' attitudes toward their decision to have SG and decision regret rates up to 6 years postoperatively. METHODS: We surveyed 185 patients who were at least 6 months post-SG (response rate 30%). We used a modified version of the Decision Regret Scale developed by Brehaut et al. We converted responses to a 0-100 scale so that higher scores (> 50) reflect greater regret. We characterized patients who expressed having overall decision regret (score > 50) vs. those who did not (≤ 50). Demographic and preoperative clinical information was extracted from the online medical records. RESULTS: Of 185 SG patients, only 13 (7%) reported regret scores > 50 (i.e. high decision regret). Mean time from SG to survey completion was 41 months (range 6-76 months). Unadjusted comparisons between the two groups revealed that patients with high regret scores had lower mean weight loss (32.1% vs. 48.9% EBMIL), and reported less improvement in quality-of-life (QoL), such as physical health (46.2% vs. 93.5% "somewhat" or "significantly" improved). The two groups were similar in short-term complications, but those reporting overall regret were more likely to report GI complaints such as bloating (61.5% vs. 30.4%). Finally, patients with regret scores > 50 were more likely to be further out from SG (median time since surgery 61.8 vs. 41.1 months). CONCLUSION: In our study, very few patients reported regret (7%) up to 6 years postoperatively, in line with prior reports after RYGB. Those with regret reported poorer QoL.

Distractions in the operating room: a survey of the healthcare team.

BACKGROUND: Distractions during surgical procedures are associated with team inefficiency and medical error. Little is published about the healthcare provider's perception of distraction and its adverse impact in the operating room. We aim to explore the perception of the operating room team on multiple distractions during surgical procedures. METHODS: A 26-question survey was administered to surgeons, anesthesia team members, nurses, and scrub technicians at our institution. Respondents were asked to identify and rank multiple distractions and indicate how each distraction might affect the flow of surgery. RESULTS: There was 160 responders for a response rate of 19.18% (160/834), of which 71 (44.1%) male and 82 (50.9%) female, 48 (29.8%) surgeons, 59 (36.6%) anesthesiologists, Certified Registered Nurse Anesthetists (CRNA), and 53 (32.9%) OR nurses and scrub technicians. Responders were classified into a junior group (< 10 years of experience) and a senior group (≥ 10 years). Auditory distraction followed by equipment were the most distracting factors in the operating room. All potential auditory distractions in this survey were associated with higher percentage of certain level of negative impact on the flow of surgery except for music. The top 5 distractors belonged to equipment and environment categories. Phone calls/ pagers/ beepers and case relevant communications were consistently among the top 5 most common distractors. Case relevant communications, music, teaching, and consultation were the top 4 most perceived positive impact on the flow of surgery. Distractors with higher levels of "bothersome" rating appeared to associate with a higher level of perceived negative impact on the flow of surgery. Vision was the least distracting factor and appeared to cause minimal positive impact on the flow of surgery. CONCLUSIONS: To our knowledge, this is the first survey studying perception of surgery, anesthesia, and OR staff on various distractions in the operating room. Fewer unnecessary distractions might improve the flow of surgery, improve OR teamwork, and potentially improve patient outcomes.

Ecological momentary assessment of changes in eating behaviors, appetite, and other aspects of eating regulation in Roux-en-Y gastric bypass and sleeve gastrectomy patients.

Bariatric surgery can have profound impacts on eating behaviors and experiences, yet most prior research studying these changes has relied on retrospective self-report measures with limited precision and susceptibility to bias. This study used smartphone-based ecological momentary assessment (EMA) to evaluate the trajectory of change in eating behaviors, appetite, and other aspects of eating regulation in 71 Roux-en-Y gastric bypass and sleeve gastrectomy patients assessed preoperatively and at 3, 6, and 12-months postoperative. For some outcomes, results showed a consistent and similar pattern for SG and RYGB where consumption of sweet and high-fat foods and hunger, desire to eat, ability to eat right now, and satisfaction with amount eaten all improved from pre-to 6-months post-surgery with some degree of deterioration at 12-months post-surgery. By contrast, other variables, largely related to hedonic hunger and craving and desire for specific foods, showed less consistent patterns that differed by surgery type. While the findings suggest an overall pattern of improvement in eating patterns following bariatric surgery, they also highlight how a return to preoperative habits may begin as early as 6 months after surgery. Additional research is needed to understand mechanisms that promote changes in eating behavior after surgery, and how best to intervene to preserve beneficial effects.

Laparoscopic adjustable gastric band remains a safe, effective, and durable option for surgical weight loss.

BACKGROUND: Despite many patients doing well after laparoscopic adjustable gastric band (LAGB) several studies caution offering this procedure for weight loss. The aim of our study was to review our long-term results over a decade. METHODS: Following IRB approval, the Metabolic and Bariatric Surgery Quality Improvement Program (MBSAQIP) Data Registry was used to identify LAGB placement between 2007 and 2013 by a single surgeon. We sought to determine complications of initial operation, weight loss and resolution of comorbidities over time, the indications for reoperation including removal, revision or conversion to another weight loss surgery. Chi-square test was used to analysis. RESULTS: From 403 LAGB performed between January 2007 and December 2013, 75 patients required reoperation with total 79 procedures, including band revision and/or conversion. Mean follow-up time was 5.78 years (73.67 months). The rate of reoperation was at least 18.61%. There were 60 band removals, 10 band revisions, 9 conversions to either sleeve or gastric bypass. Only 16 patients (20.25%) required reoperation due to inadequate weight loss. Band slippage/prolapse remained the most common non weight-related indication for reoperation (23, 29.11%). Reoperation associated with longer length of stay compared to index procedures (2.12 days vs 1.63 days, p < 0.0001) but no statistical difference in 30_days_complication. Of those who did not require reoperation, BMI at 10th year follow-up was 37.50 from initial BMI of 42.23 with EWL of 39.22%. CONCLUSIONS: Lap band is effective for most patients with long-term durability. Over time approximately one fifth will need additional surgery. Only one fifth of reoperation relates to inadequate weight loss.

Safer operating room teams: rationale for the fundamental use of surgical energy (FUSE) hospital compliance module.

BACKGROUND: The Fundamental Use of Surgical Energy (FUSE) program was developed by The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) to promote the safe use of surgical energy. A curriculum that could be used in hospital educational programs was needed to expand access. The goal of this project was to develop a short, inexpensive, online module that emphasizes key FUSE learning objectives. The accompanying survey assessed perceived relevancy. METHODS: The SAGES FUSE Committee developed the Hospital Compliance Module. The target audience included all OR personnel. The Module was piloted at Beth Israel Deaconess Medical Center. The data were analyzed using Chi-square with Yates' correction two-tailed test. RESULTS: Three-hundred-eighty individuals completed the survey: 198 (52%) surgeons, 139 (37%) nurses, 28 (7%) surgical technicians, and 15 (4%) house staff. For "…the Module taught me valuable information" 155 (41%) responded extremely and 350 (92%) responded at least somewhat. For "As a result of [the Module] how likely are you to change how you set up or use energy devices…?" 103 (27%) responded extremely and 305 (80%) responded at least somewhat. For "How likely are you to recommend this compliance module…?" 143 (38%) responded extremely and 333 (88%) responded at least somewhat. CONCLUSION: The FUSE Hospital Compliance Module is effective and efficient. It should be considered for widespread distribution by hospitals to enhance staff education.

Does your team know how to respond safely to an operating room fire? Outcomes of a virtual reality, AI-enhanced simulation training.

BACKGROUND: Operating room (OR) fires are rare but devastating events requiring immediate and effective response. Virtual Reality (VR) simulation training can provide a safe environment for practice of skills in such highly stressful situation. This study assessed interprofessional participants' ability to respond to VR-simulated OR fire scenarios, attitudes, numbers of attempt of the VR simulation do participants need to successfully respond to OR fires and does prior experience, confidence level, or professional role predict the number of attempts needed to demonstrate safety and pass the simulation. METHODS: 180 surgical team members volunteered to participate in this study at Beth Israel Deaconess Medical Center, Boston, MA. Each participant completed five VR OR simulation trials; the final two trials incorporated AI assistance. Primary outcomes were performance scores, number of attempts needed to pass, and pre- and post-survey results describing participant confidence and experiences. Differences across professional or training role were assessed using chi-square tests and analyses of variance. Differences in pass rates over time were assessed using repeated measures logistic regression. RESULTS: One hundred eighty participants completed simulation testing; 170 (94.4%) completed surveys. Participants included surgeons (17.2%), anesthesiologists (10.0%), allied health professionals (41.7%), and medical trainees (31.1%). Prior to training, 45.4% of participants reported feeling moderately or very confident in their ability to respond to an OR fire. Eight participants (4.4%) responded safely on the first simulation attempt. Forty-three participants (23.9%) passed by the third attempt (VR only); an additional 97 participants (53.9%) passed within the 4-5th attempt (VR with AI assistance). CONCLUSIONS: Providers are unprepared to respond to OR fires. VR-based simulation training provides a practical platform for individuals to improve their knowledge and performance in the management of OR fires with a 79% pass rate in our study. A VR AI approach to teaching this essential skill is innovative, feasible, and effective.

International Delphi Expert Consensus on Safe Return to Surgical and Endoscopic Practice: From the Coronavirus Global Surgical Collaborative.

OBJECTIVE: The aim of this work is to formulate recommendations based on global expert consensus to guide the surgical community on the safe resumption of surgical and endoscopic activities. BACKGROUND: The COVID-19 pandemic has caused marked disruptions in the delivery of surgical care worldwide. A thoughtful, structured approach to resuming surgical services is necessary as the impact of COVID-19 becomes better controlled. The Coronavirus Global Surgical Collaborative sought to formulate, through rigorous scientific methodology, consensus-based recommendations in collaboration with a multidisciplinary group of international experts and policymakers. METHODS: Recommendations were developed following a Delphi process. Domain topics were formulated and subsequently subdivided into questions pertinent to different aspects of surgical care in the COVID-19 crisis. Forty-four experts from 15 countries across 4 continents drafted statements based on the specific questions. Anonymous Delphi voting on the statements was performed in 2 rounds, as well as in a telepresence meeting. RESULTS: One hundred statements were formulated across 10 domains. The statements addressed terminology, impact on procedural services, patient/staff safety, managing a backlog of surgeries, methods to restart and sustain surgical services, education, and research. Eighty-three of the statements were approved during the first round of Delphi voting, and 11 during the second round. A final telepresence meeting and discussion yielded acceptance of 5 other statements. CONCLUSIONS: The Delphi process resulted in 99 recommendations. These consensus statements provide expert guidance, based on scientific methodology, for the safe resumption of surgical activities during the COVID-19 pandemic.

Team training and surgical crisis management.

Team training and crisis management derive their roots from fundamental learning theory and the culture of safety that burgeoned forth from the industrial revolution through the rise of nuclear energy and aviation. The integral nature of telemedicine to many simulation-based activities, whether to bridge distances out of convenience or necessity, continues to be a common theme moving into the next era of surgical safety as newer, more robust technologies become available.

Virtual reality operating room with AI guidance: design and validation of a fire scenario.

BACKGROUND: Operating room (OR) fires are uncommon but disastrous events. Inappropriate handling of OR fires can result in injuries, even death. Aiming to simulate OR fire emergencies and effectively train clinicians to react appropriately, we have developed an artificial intelligence (AI)-based OR fire virtual trainer based on the principle of the "fire triangle" and SAGES FUSE curriculum. The simulator can predict the user's actions in the virtual OR and provide them with timely feedback to assist with training. We conducted a study investigating the validity of the AI-assisted OR fire trainer at the 2019 SAGES Learning Center. METHODS: Fifty-three participants with varying medical experience were voluntarily recruited to participate in our Institutional Review Board approved study. All participants were asked to contain a fire within the virtual OR. Participants were then asked to fill out a 7-point Likert questionnaire consisting of ten questions regarding the face validation of the AI-assisted OR fire simulator. Shapiro-Wilk tests were conducted to test normality of the scores for each trial. A Friedman's ANOVA with post hoc tests was used to evaluate the effect of multiple trials on performance. RESULTS: On a 7-point scale, eight of the ten questions were rated a mean of 6 or greater (72.73%), especially those relating to the usefulness of the simulator for OR fire-containing training. 79.25% of the participants rated the degree of usefulness of AI guidance over 6 out of 7. The performance of individuals improved significantly over the five trials, χ2(4) = 119.89, p < .001, and there was a significant linear trend of performance r = .97, p = 0.006. A pairwise analysis showed that only after the introduction of AI did performance improve significantly. CONCLUSIONS: The AI-guided OR fire trainer offers the potential to assess OR personnel and teach the proper response to an iatrogenic fire scenario in a safe, repeatable, immersive environment.

Use of Fundamentals of Laparoscopic Surgery Testing to Assess Gynecologic Surgeons: A Retrospective Cohort Study of 10-Years Experience.

STUDY OBJECTIVE: To compare the Fundamentals of Laparoscopic Surgery (FLS) exam scores between obstetrics and gynecology (OBGYN) and general surgery (GS) providers. DESIGN: This is a retrospective cohort study at a single institution from July 2007 to May 2018. Categorical and continuous variables were analyzed with χ2 test, t test, and Wilcoxon rank sum test. SETTING: Beth Israel Deaconess Medical Center (BIDMC), Boston, MA, a tertiary care academic medical center. PATIENTS: All providers who took the FLS exam at the Carl J. Shapiro Simulation and Skills Center at BIDMC. INTERVENTIONS: FLS certification. MEASUREMENTS AND MAIN RESULTS: A total of 205 BIDMC trainees and faculty took the FLS exam between July 2007 and May 2018, of which 176 were identified to be OBGYN or GS providers. The FLS certification pass rate was high for both specialties (97.0% OBGYN vs 96.1% sGS, p = .76). When comparing all providers, no significant difference was found in the mean manual skill test scores between surgical specialties (594.9 OBGYN vs 601.0 GS, p = .59); whereas, a significant difference was noted in the mean cognitive scores, with GS providers scoring higher than OBGYN providers (533.8 OBGYN vs 583.4 GS, p <.001). However, when adjusting for several variables in a multivariate linear regression model, surgical specialty was not a predictor for cognitive scores. In the multivariate analysis, age, sex, and test year were predictors for cognitive scores, with higher scores associated with younger age, male sex, and advancing calendar year. None of the variables were significant predictors of manual scores. CONCLUSION: Both OBGYN and GS providers had extremely high FLS pass rates. In the multivariate analysis, surgical specialty was not a predictor for higher FLS test scores for either manual or cognitive test scores. Although OBGYN residency programs offer fewer years of training, OBGYN trainees demonstrate the capacity to perform well on the FLS exam.

Surgeons With Five or More Actual Cricothyrotomies Perform Significantly Better on a Virtual Reality Simulator.

BACKGROUND: Discriminating performance of learners with varying experience is essential to developing and validating a surgical simulator. For rare and emergent procedures such as cricothyrotomy (CCT), the criteria to establish such groups are unclear. This study is to investigate the impact of surgeons' actual CCT experience on their virtual reality simulator performance and to determine the minimum number of actual CCTs that significantly discriminates simulator scores. Our hypothesis is that surgeons who performed more actual CCT cases would perform better on a virtual reality CCT simulator. METHODS: 47 clinicians were recruited to participate in this study at the 2018 annual conference of the Society of American Gastrointestinal and Endoscopic Surgeons. We established groups based on three different experience thresholds, that is, the minimal number of CCT cases performed (1, 5, and 10), and compared simulator performance between these groups. RESULTS: Participants who had performed more clinical cases manifested higher mean scores in completing CCT simulation tasks, and those reporting at least 5 actual CCTs had significantly higher (P = 0.014) simulator scores than those who had performed fewer cases. Another interesting finding was that classifying participants based on experience level, that is, attendings, fellows, and residents, did not yield statistically significant differences in skills related to CCT. CONCLUSIONS: The simulator was sensitive to prior experience at a threshold of 5 actual CCTs performed.

Less pain and earlier discharge after implementation of a multidisciplinary enhanced recovery after surgery (ERAS) protocol for laparoscopic sleeve gastrectomy.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) may be complicated by postoperative pain, nausea, and vomiting, with consequent increases in length of stay (LOS), decreased patient satisfaction, and higher costs. While enhanced recovery after surgery (ERAS) protocols have been in circulation for many years, there is no standard ERAS protocol for bariatric surgery. METHODS: Data were collected prospectively and compared to a historical control. All patients undergoing LSG, ages 18 to 75, were included in the pathway; those with preoperative chronic opioid use were excluded from our results. Statistical analysis was performed using t-statistics and chi-squared test. Ninety patients undergoing LSG, performed by a single surgeon, were included in our ERAS group from November 26, 2018, to April 30, 2019, and were compared to a historical control of 570 patients who underwent LSG over the previous 5 years (pre-ERAS). Measured outcomes included discharge opioid prescriptions issued, hospital length of stay, 30-day readmissions, reoperations, morbidity, and mortality. RESULTS: Ten (11%) ERAS patients vs 100% of pre-ERAS patients received opioid prescriptions upon, or after, discharge (p < 0.001). The ERAS group LOS decreased to 1.36 days vs 2.40 days in the pre-ERAS group (p < 0.001). 30-day readmission rates were 0% for ERAS patients vs 3.09% for pre-ERAS patients (p = 0.149). 30-day reoperation rates were 0% for ERAS patients vs 0.54% for pre-ERAS patients (p = 1). Thirty-day morbidity rates were 3.33% (3) for ERAS patients vs 3.27% for pre-ERAS patients (p = 1); there was no 30-day mortality in either group. CONCLUSION: ERAS for LSG results in a clinical and statistically significant reduction in postoperative opioid use and LOS, without increasing 30-day readmissions, reoperations, morbidity, or mortality.

Endoscopic submucosal dissection: a cognitive task analysis framework toward training design.

BACKGROUND: One of the major impediments to the proliferation of endoscopic submucosal dissection (ESD) training in Western countries is the lack of sufficient experts as instructors. One way to address this gap is to develop didactic systems, such as surgical simulators, to support the role of trainers. Cognitive task analysis (CTA) has been used in healthcare for the design and improvement of surgical training programs, and therefore can potentially be used for design of similar systems for ESD. OBJECTIVE: The aim of the study was to apply a CTA-based approach to identify the cognitive aspects of performing ESD, and to generate qualitative insights for training. MATERIALS AND METHODS: Semi-structured interviews were designed based on the CTA framework to elicit knowledge of ESD practitioners relating to the various tasks involved in the procedure. Three observations were conducted of expert ESD trainers either while they performed actual ESD procedures or at a training workshop. Interviews were either conducted over the phone or in person. Interview participants included four experts and four novices. The observation notes and interviews were analyzed for emergent qualitative themes and relationships. RESULTS: The qualitative analysis yielded thematic insights related to four main cognition-related categories: learning goals/principles, challenges/concerns, strategies, and decision-making. The specific insights under each of these categories were systematically mapped to the various tasks inherent to the ESD procedure. CONCLUSIONS: The CTA approach was applied to identify cognitive themes related to ESD procedural tasks. Insights developed based on the qualitative analysis of interviews and observations of ESD practitioners can be used to inform the design of ESD training systems, such as virtual reality-based simulators.

SAGES masters program: determining the seminal articles for each pathway.

BACKGROUND: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) has recently developed and announced its Masters Program that aims to address existing needs of practicing surgeons for lifelong learning and consists of eight clinical pathways each containing three anchoring procedures. The objective of this study was to select the seminal articles for each anchoring procedure of these pathways using a systematic methodology. METHODS: A systematic literature search of Web of Science was conducted for the most cited articles for each of the anchoring procedures of the SAGES Masters pathways. The most relevant identified articles were then reviewed by expert members of the relevant SAGES pathway committees and task forces and the seminal articles chosen for each anchoring procedure using expert consensus. RESULTS: 578 highly cited articles were identified by the original search of the literature and the seminal articles were selected for each anchoring procedure after expert review and consensus. Articles address procedural outcomes, disease pathophysiology, and surgical technique and are presented in this paper. CONCLUSIONS: We have identified seminal articles for each anchoring procedure of the SAGES Masters program pathways using a systematic methodology. These articles provide surgeon participants of this program with a great resource to improve their procedure-specific knowledge and may further benefit the larger surgical community by focusing its attention to must-read impactful work that may inform best practices.

A task and performance analysis of endoscopic submucosal dissection (ESD) surgery.

BACKGROUND: ESD is an endoscopic technique for en bloc resection of gastrointestinal lesions. ESD is a widely-used in Japan and throughout Asia, but not as prevalent in Europe or the US. The procedure is technically challenging and has higher adverse events (bleeding, perforation) compared to endoscopic mucosal resection. Inadequate training platforms and lack of established training curricula have restricted its wide acceptance in the US. Thus, we aim to develop a Virtual Endoluminal Surgery Simulator (VESS) for objective ESD training and assessment. In this work, we performed task and performance analysis of ESD surgeries. METHODS: We performed a detailed colorectal ESD task analysis and identified the critical ESD steps for lesion identification, marking, injection, circumferential cutting, dissection, intraprocedural complication management, and post-procedure examination. We constructed a hierarchical task tree that elaborates the order of tasks in these steps. Furthermore, we developed quantitative ESD performance metrics. We measured task times and scores of 16 ESD surgeries performed by four different endoscopic surgeons. RESULTS: The average time of the marking, injection, and circumferential cutting phases are 203.4 (σ: 205.46), 83.5 (σ: 49.92), 908.4 s. (σ: 584.53), respectively. Cutting the submucosal layer takes most of the time of overall ESD procedure time with an average of 1394.7 s (σ: 908.43). We also performed correlation analysis (Pearson's test) among the performance scores of the tasks. There is a moderate positive correlation (R = 0.528, p = 0.0355) between marking scores and total scores, a strong positive correlation (R = 0.7879, p = 0.0003) between circumferential cutting and submucosal dissection and total scores. Similarly, we noted a strong positive correlation (R = 0.7095, p = 0.0021) between circumferential cutting and submucosal dissection and marking scores. CONCLUSIONS: We elaborated ESD tasks and developed quantitative performance metrics used in analysis of actual surgery performance. These ESD metrics will be used in future validation studies of our VESS simulator.

Cardiovascular and Ventilatory Consequences of Laparoscopic Surgery.

Although laparoscopic surgery accounts for >2 million surgical procedures every year, the current preoperative risk scores and guidelines do not adequately assess the risks of laparoscopy. In general, laparoscopic procedures have a lower risk of morbidity and mortality compared with operations requiring a midline laparotomy. During laparoscopic surgery, carbon dioxide insufflation may produce significant hemodynamic and ventilatory consequences such as increased intraabdominal pressure and hypercarbia. Hemodynamic insults secondary to increased intraabdominal pressure include increased afterload and preload and decreased cardiac output, whereas ventilatory consequences include increased airway pressures, hypercarbia, and decreased pulmonary compliance. Hemodynamic effects are accentuated in patients with cardiovascular disease such as congestive heart failure, ischemic heart disease, valvular heart disease, pulmonary hypertension, and congenital heart disease. Prevention of cardiovascular complications may be accomplished through a sound understanding of the hemodynamic and physiological consequences of laparoscopic surgery as well as a defined operative plan generated by a multidisciplinary team involving the preoperative consultant, anesthesiologist, and surgeon.

Barriers to implementation of the FUSE program.

INTRODUCTION: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) developed The Fundamental Use of Surgical Energy (FUSE) Program to promote safe use of energy devices in the operating room and endoscopy suite. Utilization of the program has been slower than anticipated. This study aims to determine the barriers to implementing FUSE. METHODS: An anonymous survey was distributed to a surgery department at an academic teaching hospital (n = 256). Participants indicated their level of training. Answers were measured using a 5-point Likert scale. RESULTS: There were 94 (36.7%) respondents to the survey from September 7 to 20, 2016. Fifteen surveys were incomplete, leaving 79 responses for analysis. Most respondents were at the faculty level (45/79, 57.0%). The majority had heard of FUSE (62/79, 78.5%), but only 19 had completed the certification (19/62, 32.3%). There was no difference in the completion rate between faculty and trainees (26.7 vs. 20.6%, OR 1.4, 95% CI 0.49-4.06, p = 0.53). The most common reasons for not taking the exam were lack of time to study (26/43, 60.5%) and lack of time to take the exam (28/43, 62.1%); however, cost was not a barrier (12/43, 27.9%). The majority identified a personal learning gap regarding the safe use of surgical energy (30/43, 69.7%). Of the 19 FUSE-certified respondents, reasons cited for completing the exam included wanting to prevent adverse events to patients and in the operating room (17/19, 89.5% and 17/19, 89.5%), and the belief that the course would make them a safer surgeon (16/19, 84.2%). CONCLUSIONS: FUSE teaches the proper use of radiofrequency energy, how to prevent unnecessary injury, and promotes safe practice. Close to three out of every four surgeons self-identified a personal knowledge gap regarding the safe use of surgical energy. Time restraints were cited most commonly as the barrier to starting and completing FUSE. Integrating the FUSE program into resident educational conferences, faculty grand rounds, or national conferences may help improve participation and drive adoption of FUSE certification.
