In recent years, as the high burden of surgical disease and poor access to surgical care in low- and middle-income countries have gained recognition as major public health problems, interest in global health has surged among surgical trainees and faculty. Traditionally, clinical volunteerism was at the forefront of the high-income country response to the significant burden of surgical disease in low- and middle-income countries. However, sustainable strategies for providing surgical care in low- and middle-income countries increasingly depend on bilateral clinical, research, and education collaborations to ensure effective resource allocation and contextual relevance. Academic global surgery creates avenues for interested surgeons to combine scholarship and education with their clinical global surgery passions through incorporation of basic/translational, education, clinical outcomes, or health services research with global surgery. Training in global health, either within residency or through advanced degrees, can provide the necessary skills to develop and sustain such initiatives. We further propose that creating cross-continental, bidirectional collaborations can maximize funding opportunities. Academic institutions are uniquely positioned to lead longitudinal and, importantly, sustainable global surgery efforts. However, for the individual global surgeon, the career path forward may be unclear. This paper reviews the development of academic global surgery, delineates the framework and factors critical to training global surgeons, and proposes models for establishing an academic career in this field. Overall, with determination, the academic global surgeon will not only carve out a niche of expertise but will define this critical field for future generations.

Global surgery is an emerging academic discipline that is developing in tandem with numerous policy and advocacy initiatives. In this regard, academic global surgery will be crucial for measuring the progress toward improving surgical care worldwide. However, as a nascent academic discipline, there must be rigorous standards for the quality of work that emerges from this field. In this white paper, which reflects the opinion of the Global Academic Surgery Committee of the Society for University Surgeons, we discuss the importance of research in global surgery, the methodologies that can be used in such research, and the challenges and benefits associated with carrying out this research. In each of these topics, we draw on existing examples from the literature to demonstrate our points. We conclude with a call for continued, high-quality research that will strengthen the discipline's academic standing and help us move toward improved access to and quality of surgical care worldwide.

Surgeons are traditionally categorized as working either in academic or private/community practice, but some transition between the two environments. Here, we profile current academic cardiothoracic surgeons who began their attending careers in private or community practice. We hypothesized that research activity may distinguish cardiothoracic surgeons who started in non-academic versus academic practice.Publicly available data regarding professional history and research productivity were collected for 992 academic cardiothoracic surgeons on faculty at the 77 cardiothoracic surgery training programs in the United States in 2018. Data are presented as medians analyzed with the Mann-Whitney test or proportions analyzed with Fisher exact test or the χA total of 80 (8.1%) academic cardiothoracic surgery faculty started their careers in non-academic practice, and 912 (91.9%) started directly in academia. Those who started in non-academic practice spent a median 7.0 y in private/community practice and were more likely to be cardiac surgeons (68.8% vs 51.6%, P = .0132). They were equally likely to pursue a protected research fellowship (56.3% vs 57.0%, P = .9067) and publish research during training (92.5% vs 91.1%, P = .8374), but they published fewer total papers by the end of cardiothoracic surgery fellowship (3.0 vs 7.0, P = .0001) and fewer papers per year as an academic attending (0.8 vs 2.9, P.0001). Nevertheless, the majority of cardiothoracic surgery faculty who started in non-academic practice are currently active in research (68.8%), and 2 such surgeons received National Institutes of Health R01 funding.Transitioning from non-academic to academic practice is an uncommon but feasible pathway for interested cardiothoracic surgeons.

The risk of port-site metastasis after laparoscopic removal of incidental gallbladder cancer was previously estimated to be 14-30%. The present study was designed to determine the incidence of port-site metastasis in incidental gallbladder cancer in the modern era (2000-2014) versus the historic era (1991-1999). We also investigated the site of port-site metastasis.Using PRISMA, a systematic review was conducted to identify papers that addressed the development of port-site metastasis after laparoscopic resection of incidental gallbladder cancer. Studies that described cancer-specific outcomes in ≥5 patients were included. A validated quality appraisal tool was used, and a weighted estimate of the incidence of port-site metastasis was calculated.Based on data extracted from 27 papers that met inclusion criteria, the incidence of port-site metastasis in incidental gallbladder cancer has decreased from 18.6% prior to 2000 (95% confidence interval 15.3-21.9%, n = 7) to 10.3% since then (95% confidence interval 7.9-12.7%, n = 20) (P .001). The extraction site is at significantly higher risk than nonextraction sites.The incidence of port-site metastasis in incidental gallbladder cancer has decreased but remains high relative to other primary tumors. Any preoperative finding that raises the suspicion of gallbladder cancer should prompt further investigation and referral to a hepato-pancreato-biliary specialist.

Background The Surgeon General oversees the Commissioned Corps of the U.S. Public Health Service (USPHS) and is viewed as the “Nation’s Doctor,” responsible for providing the public with information on living healthier and safer lives. The Surgeon General’s influence is seen through public health initiatives such as warning labels on tobacco and alcohol products. The objectives of this paper are to describe the tradition of the Office of the Surgeon General as created by Dr John M. Woodworth and to describe the careers of Dr C. Everett Koop and Dr Richard H. Carmona—the only 2 surgeons by training to hold the role. Methods This is a historical literature review using a combination of primary and secondary sources. Results Dr Woodworth set the priorities and responsibilities of the Surgeon General’s Office: education, public service, sanitation, and public health. Dr Koop is widely regarded as the most influential Surgeon General of all time. He was both a pioneer in pediatric surgery and a highly influential public figure, issuing landmark reports on smoking, violence, and AIDS. Dr Carmona is a trauma surgeon by training and focused on the dangers of second-hand smoke as Surgeon General. Dr Carmona served in a more political role as Surgeon General, eventually running for Senate at the end of his term. Conclusion This brief review of the history of the Surgeon General’s Office highlights the contributions of the first Surgeon General and the only 2 surgeons who have held the position.

Background Subtotal cholecystectomy is recognized as a rescue procedure performed in grossly suboptimal circumstances that would deem a total cholecystectomy too risky to execute. An earlier systematic review based on 30 studies published between 1985 and 2013 concluded that subtotal cholecystectomy had a morbidity rate comparable to that of total cholecystectomy. This systematic review appraises 17 clinical outcomes in patients undergoing subtotal cholecystectomy. Methods The study protocol was registered with the International Prospective Register for Systematic Reviews (CRD42020172808). MEDLINE, Embase, Cochrane bibliographic databases, and Google Scholar were used to identify papers published between 1985 and June 2020. Data related to the surgical setting, approach, intervention on the hepatic wall of the gallbladder, type of completion of subtotal cholecystectomy, year of study, and study design were collected. Seventeen clinical outcomes were considered. Meta-analyses were performed using a random-effects model, and the effect size was presented as risk ratios with 95% confidence intervals. Results From 1,017 records, 85 eligible studies were identified and included. These included 3,645 patients who underwent subtotal cholecystectomy. Laparoscopic (80.1%, n = 2,918) and reconstituting (74.6%, n = 2,719) approaches represented the majority of all subtotal cholecystectomy cases. Seven (0.2%) cases of injury to the bile duct were reported. Bile leak was reported in 506 (13.9%) patients. Reconstituting subtotal cholecystectomy was associated with a lower risk for 11 clinical outcomes. Open subtotal cholecystectomy was associated with an increased rate of 30-day mortality and wound infections. Conclusion Subtotal cholecystectomy is associated with significant morbidity. Laparoscopic and reconstituting surgery may reduce the risks of some perioperative complications and long-term sequelae after subtotal cholecystectomy.

Background A minimally invasive step-up approach to necrotizing biliary pancreatitis often requires multiple interventions, delaying cholecystectomy. The risk of gallstone-related complications during this time interval is unknown, as is the feasibility and safety of cholecystectomy after minimally invasive step-up treatment. In this paper, we analyzed both. Methods Necrotizing pancreatitis patients treated with a minimally invasive step-up approach who underwent interval cholecystectomy at 2 tertiary care centers between 2014 and 2019 were included. Gallstone-related complications prior to cholecystectomy were examined, as were surgical approaches to cholecystectomy and complications. Necrotizing pancreatitis patients treated without mechanical intervention were also examined. Results Seven of 31 patients developed gallstone-related complications between minimally invasive step-up treatment initiation and cholecystectomy. One patient developed biliary colic. Six patients developed acute cholecystitis. Two of these patients also developed choledocholithiasis, and 1 developed cholangitis, all requiring endoscopic retrograde cholangiopancreatography. Cholecystectomy was performed laparoscopically in 27 of 31 patients. One patient required open conversion, and 3 patients underwent planned cholecystectomy during another open operation. Four patients developed postoperative complications. Two of 14 necrotizing pancreatitis patients treated without mechanical intervention developed recurrent pancreatitis while awaiting cholecystectomy. Conclusion Over 20% of necrotizing pancreatitis patients treated by a minimally invasive step-up approach developed gallstone-related complications while awaiting cholecystectomy. Laparoscopic cholecystectomy is feasible and safe in the great majority of necrotizing pancreatitis patients treated by a minimally invasive step-up approach.

Background Pancreatic neuroendocrine neoplasms are a heterogenous group of rare tumors whose natural history remains poorly defined. Accurate prognostication of pancreatic neuroendocrine neoplasms is essential for guiding clinical decisions. This paper aims to summarize all the commonly utilized and recently proposed prognostication systems for pancreatic neuroendocrine neoplasms published in the literature to date. Methods A systematic review of Pubmed, Scopus, and Embase databases, of the period from January 1, 2000–November 29, 2016, was conducted to identify all published articles reporting on prognostication systems of pancreatic neuroendocrine neoplasms. Results A total of 23 articles were included in our review, and a total of 25 classification systems were identified. There were 2 modifications of the World Health Organization 2004 criteria, 4 modifications of the World Health Organization 2010 criteria, 2 modifications of the American Joint Committee on Cancer 2010 staging system, 3 modifications of the European Neuroendocrine Tumor Society 2006 tumor, node, metastasis staging system, 7 novel categorial classification systems, and 2 novel proposed continuous classifications. The most commonly included variables included age, size of tumor, presence of distant and lymph node metastases, Ki-67 index, and mitotic count. Conclusion Numerous prognostication systems have been proposed for pancreatic neuroendocrine neoplasms, of which the most commonly used systems presently include the World Health Organization 2010 criteria and the two tumor, node, metastasis staging systems by the European Neuroendocrine Tumor Society and the American Joint Commission on Cancer. However, prognostication systems for pancreatic neuroendocrine neoplasms continue to evolve with time as more prognostication factors are identified. More validation and comparative studies are needed to identify the most effective prognostication system.

Portal venous system thrombosis can develop after bariatric surgery. A systematic review and meta-analysis was conducted to evaluate the incidence of portal venous system thrombosis after bariatric surgery and clarify the role of anticoagulation for the prevention of portal venous system thrombosis after bariatric surgery.PubMed, EMBASE, and Cochrane Library databases were searched. The incidence of portal venous system thrombosis after bariatric surgery was pooled by a random-effect model. Subgroup analyses were performed to explore the incidence of portal venous system thrombosis according to the average duration of prophylactic anticoagulation (extended versus short-term). Meta-regression and sensitivity analyses were performed to explore the source of heterogeneity.Among 2,714 papers initially screened, 68 studies were included. Among 100,964 patients undergoing bariatric surgery, 300 developed portal venous system thrombosis. The pooled overall incidence of portal venous system thrombosis after bariatric surgery was 0.419% (95% confidence interval: 0.341%-0.505%). The pooled incidence of portal venous system thrombosis after bariatric surgery was numerically lower in patients who received extended prophylactic anticoagulation protocol after bariatric surgery than those who received short-term prophylactic anticoagulation protocol (0.184% vs 0.459%). Meta-regression analyses demonstrated that sample size (P = .006), type of surgery (P.001), and average duration of prophylactic anticoagulation (P = .024) might be sources of heterogeneity, but not region, publication year, history of bariatric surgery, follow-up duration, or use of prophylactic anticoagulation. Sensitivity analyses could not identify any source of heterogeneity. The estimated mortality of portal venous system thrombosis after bariatric surgery was 1.33%.Portal venous system thrombosis after bariatric surgery is rare, but potentially lethal. Extended prophylactic anticoagulation protocol may be considered in patients at a high risk of developing portal venous system thrombosis after bariatric surgery.

Objective We aimed to investigate clinical symptom and epidemiological features of ESP-infected COVID-19 Summary Background Data Almost one million of 2019 novel coronavirus disease (COVID-19) patients were diagnosed in the world wide from December 2019 to now. Thousands of emergency operations were carried out in the interim. However no one focused on the clinical symptom of emergency surgery patients (ESP) with COVID-19 pneumonia. Methods Retrospective cohort study of 164 ESP with or without COVID-19 pneumonia in Zhongnan Hospital of Wuhan University in Wuhan, China, from January 1 to January 20, 2020. The final date of follow-up was February 5, 2020. The associated clinical, laboratory, epidemiological, demographic, radiological and outcome data were collected and analyzed. Results Of 164 ESP, the median age was 41 years old (interquartile range (IQR), 29-89) and 136 (82.9%) were women. Associated main clinical symptom including fever (93 [56.7%]), dry cough (56 [34.2%]), fatigue (86 [52.4%]), nausea (78 [47.6%]) and dizziness (77 [47%]). Of 54 ESP-infected COVID-19 patients, the median age was 46 (IQR: 25-89) and 45 (83.3%) were women. The pathological clinical symptoms including fever (54 [100%]), fatigue (48 [88.9%]), nausea (52 [96.3%]), dizziness (46 [85.2%]) and dry cough (44 [81.5%]) were investigated; the lymphopenia (0.37×109/L [IQR: 0.23-0.65]) and increased C-reactive protein (24.7×109/L [IQR: 13.57-38]) were observed. The preoperative fever and postoperative fever in ESP with or without COVID-19 pneumonia were analyzed in this study. Of 54 ESP with COVID-19 patients, 15 (27.8%) patients showed preoperative fever, 54 (100%) had the postoperative fever; Of 110 non-COVID-19 of ESP, 5 (4.5%) patients had preoperative fever, 31 (28.2%) patients had the postoperative fever. The fever in ESP with COVID-19 lasted more than 7 days, markedly exceeded the non-COVID-19 patients (lasted about 3 days). Furthermore, 43 health care workers were infected from exposed to ESP with COVID-19 pneumonia. Conclusion In our study, the clinical symptoms of ESP-infected COVID-19 displayed marked differences from those reported common COVID-19 pneumonia cases. Additionally, the health care workers were confirmed to expose great risk in ESP with COVID-19 pneumonia. Management guidelines of ESP were described in our paper., Highlights TOC Statement- 20200643 In our study, the clinical symptoms of ESP-infected COVID-19 displayed marked differences from those reported common COVID-19 pneumonia cases and the health care workers were confirmed to expose great risk in ESP with COVID-19 pneumonia. The importance of this findings is these will provide early warning for health care workers who take care of the ESP-infected COVID-19 patients on now and in the future.

Few details are known about open-access surgery journals that solicit manuscripts via E-mail. The objectives of this cross-sectional study are to compare solicitant surgery journals with established journals and to characterize the academic credentials and reasons for publication of their authorship.We identified publishers who contacted the senior author and compared their surgery journals with 10 top-tier surgical journals and open-access medical journals. We assessed the senior authorship of articles published January 2017-March 2017 and utilized a blinded survey to determine motivations for publication.Throughout a 6-week period, 110 E-mails were received from 29 publishers distributing 113 surgery journals. Compared with established journals, these journals offered lesser publication fees, but also had lesser PubMed indexing rates and impact factors (all P.002). Professors, division chiefs, and department chairs were the senior authors of nearly half of US-published papers and spent ≈$83,000 to publish 117 articles in journals with a median impact factor of 0.12 and a 33% PubMed indexing rate. Survey responses revealed a dichotomy as 43% and 57% of authors published in these journals with and without knowledge of their solicitant nature, respectively. The most commonly reported reasons for submission included waived publication fees (50%), invitation (38%), and difficulty publishing elsewhere (12%).Despite their sparse PubMed indexing and low impact factors, many senior academic faculty publish in solicitant surgery journals. This study highlights the importance for the academic surgical community to be cognizant of the quality of a journal when reviewing the literature for research and evidence-based practice.

Simulation has become an integral part of physician education, and abundant evidence confirms that simulation-based education improves learners' skills and behaviors and is associated with improved patient outcomes. The resources required to implement simulation-based education, however, have led some stakeholders to question the overall value proposition of simulation-based education. This paper summarizes the information from a special panel on this topic and defines research priorities for the field. Future work should focus on both outcomes and costs, with robust measurement of resource investments, provider performance (in both simulation and real settings), patient outcomes, and impact on the health care organization. Increased attention to training practicing clinicians and health care teams is also essential. Clarifying the value proposition of simulation-based education will require a major national effort with funding from multiple sponsors and active engagement of a variety of stakeholders.

Many Arab countries have undergone the epidemiologic transition of diseases with increasing economic development and a proportionately decreasing prevalence of communicable diseases. With this transition, injuries have emerged as a major cause of mortality and morbidity in the Gulf Cooperation Council countries in addition to diseases of affluence. Injuries are the number one cause of years of life lost and disability-adjusted life-years in the Sultanate of Oman. The burden of injuries, which affects mostly young Omani males, has a unique geographic distribution that is in contrast to the trauma care capabilities of the country. The concentration of health care resources in the northern part of the country makes it difficult for the majority of Omanis who live elsewhere to access high-quality and time-sensitive care. A broader multisectorial national injury prevention strategy should be evidence based and must strengthen human resources, service delivery, and information systems to improve care of the injured and loss of life. This paper provides a unique overview of the Omani health system with the goal of examining its trauma care capabilities and injury control policies.

Owing to increasing external pressures on both faculty and learners, the practice of bedside teaching is declining. The objective of this paper is to provide an overview of educational strategies to foster bedside teaching in the current clinical practice environment for surgical educators. General strategies include building a culture within the program that promotes the atmosphere of a learning community, and providing scaffolding for trainees that fosters gradual progression to autonomous practice. Specific techniques for bedside teaching include CAMEO, the "one-minute preceptor", and mini-presentations or peer-teaching. The intentional and proactive implementation of these strategies alongside others can assist educators in capturing the "redeemable moments" that occur in the course of routine clinical care at the patient's bedside.

Background Handover of patient care is a critical process in the transfer of information between clinical teams and clinicians during transitions in patient care. The handover process may take many forms and is often unstructured and unstandardized, potentially resulting in error and the potential for patient harm. The Joint Commission has implicated such errors in up to 80% of sentinel events and has published guidelines (using an acronym termed SHARE) for the development of intervention tools for handover. This study aims to review interventions to improve handovers in surgery and to assess compliance of described methodologies with the guidelines of the Joint Commission for design and implementation of handover improvement tools. Methods A systematic review was conducted in line with MOOSE guidelines. Electronic databases Medline, EMBASE, and PsyInfo were searched and interventions to improve surgical handover identified. Intervention types, development methods, and outcomes were compared between studies and assessed against SHARE criteria. Results Nineteen studies were included. These studies included paper and computerized checklists, proformas, and/or standardized operating protocols for handover. All reported some degree of improvement in handover. Description of development methods, staff training, and follow-up outcome data was poor. Only a single study was able to demonstrate compliance with all 5 domains guidelines of the of Joint Commission. Conclusion Improvements in information transfer may be achieved through checklist- or proforma-based interventions in surgical handover. Although initial data appear promising, future research must be backed by robust study design, relevant outcomes, and clinical implementation strategies to identify the most effective means to improve information transfer and optimize patient outcomes.

Background This study assessed the extent to which individuals with surgically operable cancer in Southeast Asia experience financially catastrophic out-of-pocket costs, discontinuation of treatment, or death. Methods The ACTION study is a prospective, 8-country, cohort study of adult patients recruited consecutively with an initial diagnosis of cancer from public and private hospitals. Participants were interviewed at baseline and 3 months. In this paper, we identified 4,584 participants in whom surgery was indicated in initial treatment plans and assessed the following competing outcomes: death, financial catastrophe (out-of-pocket costs of >30% of annual household income), treatment discontinuation, and hospitalization without financial catastrophe incurred. We then analyzed a range of predictors using a multinomial regression model. Results Of the participants, 72% were female and 44% had health insurance at baseline. At 3 months, 31% of participants incurred financial catastrophe, 8% had died, 23% had discontinued treatment, and 38% were hospitalized but avoided financial catastrophe. Health insurance status was found to be associated with lower odds of treatment discontinuation (odds ratio [OR], 0.60; 95% CI, 0.47-0.77) relative to hospitalization without financial catastrophe. Women had greater odds of financial catastrophe than men (OR, 1.35; 95% CI, 1.05-1.74), whereas lower socioeconomic status (range of indicators) was generally found to be associated with higher odds of death, treatment discontinuation, and financial catastrophe. Conclusion Priority should be given to measures such as programs to extend social health insurance to offset the out-of-pocket costs associated with surgery for cancer faced in particular by women, the uninsured, and individuals of low socioeconomic status in Southeast Asia.

Background We systematically reviewed the literature concerning simulation-based teaching and assessment of the Accreditation Council for Graduate Medical Education professionalism competencies to elucidate best practices and facilitate further research. Methods A systematic review of English literature for “professionalism” and “simulation(s)” yielded 697 abstracts. Two independent raters chose abstracts that (1) focused on graduate medical education, (2) described the simulation method, and (3) used simulation to train or assess professionalism. Fifty abstracts met the criteria, and seven were excluded for lack of relevant information. The raters, 6 professionals with medical education, simulation, and clinical experience, discussed 5 of these articles as a group; they calibrated coding and applied further refinements, resulting in a final, iteratively developed evaluation form. The raters then divided into 2 teams to read and assess the remaining articles. Overall, 15 articles were eliminated, and 28 articles underwent final analysis. Results Papers addressed a heterogeneous range of professionalism content via multiple methods. Common specialties represented were surgery (46.4%), pediatrics (17.9%), and emergency medicine (14.3%). Sixteen articles (57%) referenced a professionalism framework; 14 (50%) incorporated an assessment tool; and 17 (60.7%) reported debriefing participants, though in limited detail. Twenty-three (82.1%) articles evaluated programs, mostly using subjective trainee reports. Conclusion Despite early innovation, reporting of simulation-based professionalism training and assessment is nonstandardized in methods and terminology and lacks the details required for replication. We offer minimum standards for reporting of future professionalism-focused simulation training and assessment as well as a basic framework for better mapping proper simulation methods to the targeted domain of professionalism.

Background It is vital for clinicians to understand and interpret correctly medical statistics as used in clinical studies. In this review, we address current issues and focus on delivering a simple, yet comprehensive, explanation of common research methodology involving receiver operating characteristic (ROC) curves. ROC curves are used most commonly in medicine as a means of evaluating diagnostic tests. Methods Sample data from a plasma test for the diagnosis of colorectal cancer were used to generate a prediction model. These are actual, unpublished data that have been used to describe the calculation of sensitivity, specificity, positive predictive and negative predictive values, and accuracy. The ROC curves were generated to determine the accuracy of this plasma test. These curves are generated by plotting the sensitivity (true-positive rate) on the y axis and 1 - specificity (false-positive rate) on the x axis. Results Curves that approach closest to the coordinate (x = 0, y = 1) are more highly predictive, whereas ROC curves that lie close to the line of equality indicate that the result is no better than that obtained by chance. The optimum sensitivity and specificity can be determined from the graph as the point where the minimum distance line crosses the ROC curve. This point corresponds to the Youden index (J), a function of sensitivity and specificity used commonly to rate diagnostic tests. The area under the curve is used to quantify the overall ability of a test to discriminate between 2 outcomes. Conclusion By following these simple guidelines, interpretation of ROC curves will be less difficult and they can then be interpreted more reliably when writing, reviewing, or analyzing scientific papers.
