RESUMEN
BACKGROUND: The role of simulation in teaching technical skills to medical students is not yet well defined. Strategies for its use may be especially relevant where teachers, time, and resources are limited, especially in low-middle-income countries. METHODS: Sixty-seven third-year and 67 fifth-year medical students at the University of Botswana were taught surgical skills by a trained peer medical student, a medical officer with no specialty training or a staff surgeon. Pre- and post-intervention performance of two basic tasks (simple interrupted suture (SIS) and laparoscopic peg transfer (LPT)) and one complex task (laparoscopic intracorporeal suture (LIS)) were assessed. Subjective measures of self-perceived performance, preparedness for internship, and interest in surgery were also measured. RESULTS: The simulation program decreased the time to complete the two basic tasks and improved the objective score for the complex task. Performance of the basic skills improved regardless of the seniority of the instructor while performance of the advanced skill improved more when taught by a staff surgeon. All students had similar improvements in their self-reported confidence to perform the skills, preparedness to assist in an operation and preparedness for internship, regardless of the seniority of their instructor. Students taught by a staff surgeon felt better prepared to assist in laparoscopic procedures. CONCLUSION: Simulation-based teaching of defined surgical skills can be effectively conducted by peers and near-peers. The implications are widespread and may be most relevant where time and resources are limited, and where experienced teachers are scarce.

BACKGROUND: Metrics of sustainability and frank descriptions of the unique challenges, successes, failures, and lessons learned from a longitudinal laparoscopic program in resource-limited environments are lacking. We set out to evaluate the safety and sustainability of the laparoscopic cholecystectomy program at Princess Marina Hospital, the largest tertiary and teaching hospital in Botswana. METHODS: We assessed the clinical outcomes of patients who underwent laparoscopic cholecystectomy, comparing them with patients who underwent open cholecystectomy from January 2013 to December 2018. Technical independence and sustainability factors were measured and discussed. RESULTS: Two hundred and twenty-six laparoscopic cholecystectomies (LC) and 39 open cholecystectomies (OC) were performed. Four surgeons who trained as part of the inaugural laparoscopic program performed 48.2% of LC. Eleven surgeons who trained elsewhere performed the remainder. Overall, 94.2% of LC were performed without expatriate surgeons. The conversion rate was 25/226 (11.1%). There were 3 bile duct injuries in the LC group (3/226, 1.3%) and none in the OC group. There was one mortality in the OC group (1/39, 2.6%) and none in the LC group. Fostering a trusting relationship among all stakeholder was identified as the major key to success, while the development of a system-based strategy was identified as the most significant ongoing challenge. CONCLUSION: The laparoscopic cholecystectomy program in Botswana initially established between 2006 and 2012 has moved into its sustainability phase, characterized by increased usage of laparoscopy and greater independent operating by local surgeons, all while maintaining patient safety. Sustaining a laparoscopic program in resource-limited environments has particular challenges which may differ from country to country.

BACKGROUND: To compare the presentation, management, and outcome of HIV-positive patients with appendicitis to those of HIV-negative patients with appendicitis. SUMMARY BACKGROUND DATA: The literature is limited regarding the impact of HIV infection on patients with appendicitis. METHODS: A retrospective review of patients with appendicitis and known HIV status admitted to Princess Marina Hospital, Gaborone, Botswana, aged 13 years and greater was performed from January 2013 to December 2015. Data on patient demographics, presentation, laboratory findings, management, and outcomes were analyzed. RESULTS: A total of 295 patients with appendicitis and known HIV status were identified, of which 119 (40.3%) were HIV positive. The median [IQR] ages for HIV-positive and HIV-negative patients were 34 [29-42] and 26 [20-33] years, respectively. The male-to-female ratio for the same two groups was 0.8:1 and 1.4:1, respectively. Presenting symptoms, signs, and white blood cell count were similar in both groups. HIV-positive patients had significantly higher overall (4.2 vs. 0.0%, p = 0.010) and postoperative (4.4 vs. 0.0%, p = 0.024) mortality rates. There was no significant difference in the total complication rate between HIV-positive and HIV-negative patients (13.2 vs. 7.9%, p = 0.192). Compared to HIV-positive patients with a CD4 count ≥200, patients with a CD4 count <200 have a significantly higher postoperative mortality rate (17.6 vs. 1.4%, p = 0.023) and a trend toward a higher total postoperative complication rate (31.3 vs. 10.8%, p = 0.054). CONCLUSION: Within our setting, HIV infection, particularly with a CD4 <200, was correlated with significantly higher mortality in patients with acute appendicitis.

BACKGROUND: Previous investigators have shown that novices are able to assess surgical skills as reliably as expert surgeons. The purpose of this study was to determine how novices and experts arrive at these graded scores when assessing laparoscopic skills and the potential implications this may have for surgical education. METHODS: Four novices and four general laparoscopic surgeons evaluated 59 videos of a suturing task using a 5-point scale. Average novice and expert evaluator scores for each video and the average number of times that scores were changed were compared. Intraclass correlation coefficients were used to determine inter-rater and test-retest reliability. Evaluators were asked to define the number of videos they needed to watch before they could confidently grade and to describe how they were able to distinguish between different levels of expertise. RESULTS: There were no significant differences in mean scores assigned by the two evaluator groups. Novices changed their scores more frequently compared to experts, but this did not reach statistical significance. There was excellent inter-rater reliability between the two groups (ICC = 0.91, CI 0.85-0.95) and good test-retest reliability (ICC > 0.83). On average, novices and experts reported that they needed to watch 13.8 ± 2.4 and 8.5 ± 2.5 videos, respectively, before they could confidently grade. Both groups also identified similar qualitative indicators (e.g., instrument control). CONCLUSION: Evaluators with varying levels of expertise can reliably grade performance of an intracorporeal suturing task. While novices were less confident in their grading, both groups were able to assign comparable scores and identify similar elements of a suturing skill as being important in terms of assessment.

BACKGROUND: This study analyzes instrument motion for segments of a defined intra-corporeal suturing task in a laparoscopic simulator. We describe a system providing real-time velocity and acceleration assessment in the performance of this task. Analysis of the deconstructed task segments allows targeted assessment and teaching. METHODS: A traditional box trainer was fitted with a custom-built motion-tracking system. Participants were stratified into novice, intermediate and expert groups. They performed a defined intra-corporeal suturing task. Real-time data were collected in four degrees of freedom (DOFs) (Roll, Surge, Pitch, Yaw). The task was then deconstructed into four segments: loading needle/pull-through, double-throw knot, first single-throw knot, and second single-throw knot. Motion analysis parameters (MAPs) were studied for each DOF. RESULTS: Sixty-four participants were tested (14 novices, 19 intermediates, 31 experts). The largest difference in MAPs was seen in the 'double-throw knot' segment. MAPs for the 'loading needle/pull-through' segment revealed differences between novices and experts in Roll and Pitch DOFs only. For the 'first single knot' segment, similar MAP trends were noted across all DOFs, with significant differences between novices versus experts and intermediates versus experts. For the 'second single knot' segment, the difference in MAPs was preserved only for novices versus experts. CONCLUSIONS: By analyzing motion for a defined suturing task in a laparoscopic simulator, we can gain insight into the specific hand motions distinguishing experts from non-experts. Such information may allow teaching in a more focused, effective and efficient manner.

SUMMARY: While initiatives exist to address the worldwide need for surgeons, none involve a student-driven solution from low- and middle-income countries (LMICs). In response to falling surgical residency enrolment in South Africa, the students at the University of Cape Town (UCT) founded the UCT Surgical Society and were subsequently instrumental in creating the International Association of Student Surgical Societies (IASSS). The IASSS currently includes 25 societies in 15 countries. Its primary objectives are building sustainable networks for mutually beneficial exchanges, supporting student-driven projects, understanding issues impacting student interest in surgery, promoting global fellowship, creating an elective database and providing assistance to student surgical societies. The IASSS is a unique student-led initiative trying to improve surgical care in LMICs.
RESUMEN
OBJECTIVE: Differences in opinion exist as to the feasibility of establishing sustainable laparoscopic programs in resource-restricted environments. At the request of local surgeons and the Ministry of Health in Botswana, a training program was established to assist local colleagues with laparoscopic surgery. We reviewed our multifaceted and evolving international collaboration and highlighted those factors that have helped or hindered this program. METHODS: From 2006 to 2012, a training program consisting of didactic teaching, telesimulation, Fundamentals of Laparoscopic Surgery certification, yearly workshops, and ongoing mentorship was established. We assessed the clinical outcomes of patients who underwent laparoscopic cholecystectomy, comparing them with patients who underwent open cholecystectomy, and measured the indicators of technical independence and program sustainability. RESULTS: Twelve surgeons participated in the training program and performed 270 of 288 laparoscopic cholecystectomies. Ninety-six open cases were performed by these and 5 additional surgeons. Fifteen laparoscopic cases were converted (5.2%). The median postoperative length of hospital stay was significantly shorter in the laparoscopic group than in the open group (1 day vs 7 days, P < 0.001). As the training program progressed, the proportion of laparoscopic cases completed without an expatriate surgeon present increased significantly (P = 0.001). CONCLUSIONS: A contextually appropriate long-term partnership may assist with laparoscopic upskilling of colleagues in low- and middle-income countries. This type of collaboration promotes local ownership and may translate into better patient outcomes associated with laparoscopic surgery. In resource-restricted environments, the factors threatening sustainability may differ from those in high-income countries and should be identified and addressed.

BACKGROUND: Laparoscopic models for ex vivo up-skilling are becoming increasingly important components of surgical education. This study aims to establish the construct validity and possible educational role of a new laparoscopic box trainer equipped with a motion-tracking device. METHODS: A structured questionnaire was used to assign participants into novice, intermediate, or expert categories according to level of experience in minimal access surgery (MAS). Participants carried out a well-defined intracorporeal suturing task. Three specific motion analysis parameters (MAPs)-velocity, acceleration, and range-were measured and analyzed as movements in the four degrees of freedom available in traditional MAS using tracking sensors at the trocar insertion sites. RESULTS: The number of extreme velocity and acceleration events in all four degrees of freedom proved capable of differentiating between participants in the three categories of surgical experience using an ANOVA test (p < 0.001). Post hoc analysis confirmed these differences in the number of extreme velocity and acceleration events between all groups tested except for the velocity of the roll between the intermediates and experts. CONCLUSION: These findings confirm construct validity for this new laparoscopic box trainer system, which employs a novel analysis based on motion parameters. Motion parameters provide information regarding the overall smoothness of the operator's instrument handling, an important aspect of a surgeon's technique. This preliminary data will be used to design a simulator with real-time motion feedback to enhance its educational value.

OBJECTIVE: To examine how a mass-gathering event (the Federation Internationale de Football Association World Cup, 2010, South Africa) impacts trauma and mortality in the pediatric (≤ 18 years) population. STUDY DESIGN: We investigated pediatric emergency visits at Cape Town's 3 largest public trauma centers and 3 private hospital groups, as well as deaths investigated by the 3 city mortuaries. We compared the 31 days of World Cup with equivalent periods from 2007-2009, and with the 2 weeks before and after the event. We also looked at the World Cup period in isolation and compared days with and without games in Cape Town. RESULTS: There was significantly decreased pediatric trauma volume during the World Cup, approximately 2/100,000 (37%) fewer injuries per day, compared with 2009 and to both pre- and post-World Cup control periods (P < .001). This decrease occurred within a majority of injury subtypes, but did not change mortality. There were temporal fluctuations in emergency visits corresponding with local match start time, with fewer all-cause emergency visits during the 5 hours surrounding this time (-16.4%, P = .01), followed by a subsequent spike (+26.2%, P = .02). There was an increase in trauma 12 hours following matches (+15.6%, P = .06). CONCLUSIONS: In Cape Town, during the 2010 Federation Internationale de Football Association World Cup, there were fewer emergency department visits for traumatic injury. Furthermore, there were fewer all-cause pediatric emergency department visits during hometown matches. These results will assist in planning for future mass-gathering events.

BACKGROUND: The global burden of surgical disease and severe shortage of trained surgeons around the world are now widely recognized. The greatest challenge in improving access to surgical care lies in sub-Saharan Africa, where the number of surgeons per population is lowest. One part of the solution may be to create programs to train surgeons locally. We present our experience with an approach to designing a contextually appropriate surgical curriculum in Botswana. METHODS: Surgical logbooks from the largest tertiary care center in Botswana, dating from 2004 through 2010, were analyzed to yield total case numbers within clearly defined categories. Case numbers and local surgical opinion were combined to design a contextually relevant curriculum, with the Surgical Council on Resident Education curriculum as a template. RESULTS: Logbook analysis revealed that general surgeons in Botswana manage burns and perform a large number of skin grafts and extremity amputations. However, they perform few colonoscopies and complex laparoscopic procedures. The new curriculum included greater emphasis on surgical subspecialty procedures and surgical management of locally relevant conditions, such as the complications of infectious diseases. Less emphasis was placed on management of uncommon conditions such as inflammatory bowel disease. CONCLUSIONS: There are important differences in the scope of general surgery and the knowledge and skills required by general surgeons in Botswana compared with their North American counterparts. We present a simple and inexpensive approach that could serve as a potential model for designing contextually relevant surgical training programs in other low-resource settings.

OBJECTIVE: Recently, there has been an explosion of interest in global surgery (GS) among students, residents and surgeons. However, little information exists regarding the ethical landscape of GS in general surgery residencies. Using an American College of Physicians position paper on the ethical obligations of global health experiences as a reference, this study provides a preliminary discussion of how GS experiences in Canadian residencies compare to the American College of Physicians-proposed ethical standards. DESIGN: The Program Director (PD) at each Canadian general surgery residency program was invited to a complete an online survey. RESULTS: All 17 PDs participated. Relative to the position paper, very few PDs included underserved settings in high income countries in their definitions of GS. Only 7 of 15 programs offer predeparture training for residents. Similarly, funding was available at less than half of all institutions. There is a need for the development of frameworks to assess the ethics of GS programs. Similarly, mechanisms on how to build relationships that are maximally beneficial for the stakeholders in resource-limited environments are not yet well established. CONCLUSIONS: This is the first study to look at the ethical GS landscape in general surgery residencies across Canada. This study may assist other residencies in the development and tailoring of ethical GS programs. These results show the need for further characterization of the training, development and monitoring of GS programs.

OBJECTIVE: Using a laparoscopic box trainer fitted with motion analysis trackers and software, we aim to identify differences between junior and senior residents performing the peg transfer task, and the impact of a distracting secondary task on performance. DESIGN: General surgery residents were asked to perform the laparoscopic peg transfer task on a trainer equipped with a motion tracker. They were also asked to perform the laparoscopic task while completing a secondary task. Extreme velocity and acceleration events of instrument movement in the 3 rotational degrees of freedom were measured during task completion. The number of extreme events, defined as velocity or acceleration exceeding 1 SD above or below their own mean, were tabulated. The performance of junior residents was compared to senior residents. SETTING: Simulation learning institute, Beaumont Hospital, Royal Oak, Michigan. PARTICIPANTS: Thirty-seven general surgery residents from Beaumont Hospital, Royal Oak. RESULTS: When completing the primary task alone, senior residents executed significantly fewer extreme motion events specific to acceleration in pitch (16.63 vs. 20.69, pâ¯=â¯0.04), and executed more extreme motion events specific to velocity in roll (16.14 vs. 15.11, pâ¯=â¯0.038), when compared to junior residents. With addition of a secondary task, senior residents had fewer extreme acceleration events specific to pitch, (14.69 vs. 22.22, p < 0.001). CONCLUSIONS: While junior and senior residents completed the peg transfer task with similar times, motion analysis identified differences in extreme motion events between the groups, even when a secondary task was added. Motion analysis may prove useful for real-time feedback during laparoscopic skill acquisition.

BACKGROUND: Several challenges exist with laparoscopic skills training in resource-restricted countries, including long travel distances required by mentors for onsite teaching. Telesimulation (TS) is a novel concept that uses the internet to link simulators between an instructor and a trainee in different locations. The purpose of this study was to determine the effectiveness of telesimulation for teaching the Fundamentals of Laparoscopic Surgery (FLS) to surgeons in Botswana, Africa. METHODS: A total of 16 surgeons from two centers in Botswana participated in this 8-week study. FLS TS was set up using two simulators, computers, webcams, and Skype software for eight surgeons in the TS group. A standard FLS simulator was available for the eight surgeons in the self-practice (SP) group. Participants in the TS group had one remote training session per week with an FLS proctor at the University of Toronto who provided feedback and demonstrated proper technique. Participants in the SP group had access to the FLS DVD and were instructed to train on FLS at least once per week. FLS post-test scores were obtained in Botswana by a trained FLS proctor at the conclusion of the study. RESULTS: Participants in the TS group had significantly higher post-test FLS scores than those in the SP group (440 +/- 56 vs. 272 +/- 95, p = 0.001). All trainees in the TS group achieved an FLS simulator certification passing score, whereas only 38% in the SP group did so (p = 0.03). CONCLUSION: Remote telesimulation is an effective method for teaching the Fundamentals of Laparoscopic Surgery in Africa, achieving a 100% FLS skills pass rate. This training platform provides a cost-effective method of teaching in resource-restricted countries and could be used to teach laparoscopic skills anywhere in the world with internet access.

The global disparities in both surgical disease burden and access to delivery of surgical care are gaining prominence in the medical literature and media. Concurrently, there is an unprecedented groundswell in idealism and interest in global health among North American medical students and trainees in anesthesia and surgical disciplines. Many academic medical centers (AMCs) are seeking to respond by creating partnerships with teaching hospitals overseas. In this article we describe six such partnerships, as follows: (1) University of California San Francisco (UCSF) with the Bellagio Essential Surgery Group; (2) USCF with Makerere University, Uganda; (3) Vanderbilt with Baptist Medical Center, Ogbomoso, Nigeria; (4) Vanderbilt with Kijabe Hospital, Kenya; (5) University of Toronto, Hospital for Sick Children with the Ministry of Health in Botswana; and (6) Harvard (Brigham and Women's Hospital and Children's Hospital Boston) with Partners in Health in Haiti and Rwanda. Reflection on these experiences offers valuable lessons, and we make recommendations of critical components leading to success. These include the importance of relationships, emphasis on mutual learning, the need for "champions," affirming that local training needs to supersede expatriate training needs, the value of collaboration in research, adapting the mission to locally expressed needs, the need for a multidisciplinary approach, and the need to measure outcomes. We conclude that this is an era of cautious optimism and that AMCs have a critical opportunity to both shape future leaders in global surgery and address the current global disparities.

Pediatric surgical education has traditionally focused on the hard cognitive and psychomotor (technical) skills. While more and more attention is being paid to softer skills such as communication, collaboration, leadership, health advocacy, professionalism and scholarship, the bulk of curricula remain focused on the hard skills. An intricate part of education is the assessment of performance. This article reviews the current literature on the assessment of cognitive and psychomotor skills, focusing particularly on the assessment of technical skills in the realm of simulation.

OBJECTIVE: In recent years, there has been an explosion of interest in global surgery (GS) among students, residents, and surgeons. However, little information regarding the landscape of GS in general surgery residencies exists. This study was therefore designed to explore the opportunities and the framework for global surgery in Canadian general surgery training programs. DESIGN: The Program Director (PD) at each Canadian general surgery residency program was invited to complete an online survey. RESULTS: All 17 PDs participated. Only 3 institutions have a formal curriculum in GS, while 9 have an Office of GS. Seven residencies mention GS on their department website. Ten of 17 residencies have had trainees participate in GS experiences in the last academic year. Funding or pre-experience training is available at less than half of all institutions. Only one residency ranked GS exposure as being "very important" to their program. Across all programs, the average ranking of GS experiences was 2.3 out of 5, which translates descriptively to being of "little importance". Despite this, 10 PDs identified GS as attractive to applicants, and 5 stated their plans to expand GS opportunities at their institution. CONCLUSIONS: This is the first study to look at the GS landscape in general surgery residencies across Canada. These results may inform graduating medical students and residents about the current status of GS in Canadian residencies. This study may also assist other residencies in the development and tailoring of GS programs.

INTRODUCTION: The use of laparoscopy in resource-restricted countries has increased in recent years. Although simulation is now considered an important adjunct to operating-room-based training for learning laparoscopic skills, there is very little literature assessing the use of simulation in resource-restricted countries. The purpose of this study was to determine the feasibility and impact of a 3-day Fundamentals of Laparoscopic Surgery (FLS) course in Botswana, Africa. METHODS: A total of 20 surgeons and trainees participated in a 3-day FLS course. A pretest FLS score was obtained for each subject, followed by 2 days of practice with feedback. A final FLS posttest score was then obtained. Participants also watched the FLS instructional CD-ROM and took the written test on day 3. RESULTS: Mean posttest scores were significantly higher than pretest scores for each FLS task and for the total normalized FLS simulator score (285 +/- 94 versus 132 +/- 92, p < 0.001). The mean score on the written test was 242 (116). In total, only two surgeons achieved a passing score on both the cognitive and skills assessment required to obtain FLS certification. CONCLUSION: To our knowledge, this is the first time the FLS program has been taught in Africa. We have shown that giving the FLS course in a resource-restricted country is feasible and resulted in a significant improvement in FLS technical skills after 3 days. Most surgeons, however, still did not reach FLS passing scores, indicating that more than 3 days will be required in future courses to help surgeons obtain FLS certification.

BACKGROUND: Traditional stratification of expertise in laparoscopic simulation assigns participants to novice, intermediate, or expert groups based on case numbers. We hypothesized that expert video assessment might refine this discrimination of psychomotor expertise, especially in light of new measurable parameters. MATERIALS AND METHODS: One hundred five participants performed a defined intracorporeal suturing task in the pediatric laparoscopic surgery simulator armed with force-sensing capabilities. Participants were stratified into novice, intermediate, and expert groups via three classification schemes: (1) number of complex laparoscopic cases, (2) self-declared level of expertise, and (3) average expert rating of participants' videos. Precision, time to task completion, and force analysis parameters (FAP = total, maximum and mean forces in three axes) were compared using one-way analysis of variance tests. P < .05 was considered significant. RESULTS: Participants stratified on the basis of case numbers and on the basis of self-declared level of expertise had statistically significant differences in time to task completion, but no significant difference in FAP. When participants were restratified according to expert assessment of their video performance, time to task completion as well as total and mean forces in X, Y, and Z axes allowed discrimination between novices, intermediates, and experts, thus establishing construct validity for the latter. Precision did not allow discrimination in any stratification scheme. CONCLUSION: Compared with traditional stratification, video assessment allows refined discrimination of psychomotor expertise within a simulator. Assessment of FAP may become a relevant tool for teaching and assessing laparoscopic skills.
