RESUMEN

BACKGROUND: After the fusion of the fields of orthopedics and trauma surgery in 2006 the educational content significantly increased. The acquisition of non-surgical diagnostic and treatment skills seems to fall behind in the classical operatively focused residency programs. This study presents a status quo of the non-surgical education and knowledge in the field of orthopedics and traumatology in Germany. METHODS: An online-based voluntary and anonymous questionnaire was conducted between June and August 2023. The questionnaire was distributed through the email lists of the German Society for Orthopedics and Traumatology (DGOU) and the German Professional Association for Orthopedics and Traumatology (BVOU). RESULTS: A total of 486 German orthopedic and trauma surgeons answered the online questionnaire (77.9% male; mean age 50.2 ± 11.8 years) and 11.5% were residents. Only 27.1% spent part of the residency training in the outpatient sector. In total 84.2% wish for an increased focus on non-operative treatment options during further education, 81.1% agreed that they have a good general understanding of non-operative treatment options and 81.0% felt confident to apply them in the daily clinical routine (residents 35.4% and 41.7%, respectively). The highest self-assessed competences were knowledge on the application of splints and casts and physiotherapy, ergotherapy and sports therapy, the lowest were knowledge on acupuncture, magnetic field therapy and nutritional aspects after trauma. In total, 77.7% stated non-surgical research projects are not supported at their institution. CONCLUSION: Orthopedic and trauma surgeons in Germany subjectively have solid knowledge on treatment options while resident physicians still need to strengthen their skills. Rotation into the outpatient sector and rehabilitation facilities as well as supporting research in the field could further improve the non-surgical skills.

RESUMEN

OBJECTIVE: Concerns exist about clinical and operative skill decay in surgery residents when they dedicate time away from clinical training to pursue research. However, it remains undetermined how to best prevent these negative impacts. Our study evaluated the perspectives of surgical research residents on interventions to improve their reentry into clinical training. DESIGN, SETTING, AND PARTICIPANTS: An anonymous web-based survey was distributed between 5/01/2023 and 6/01/2023 to 102 current and former (within the previous 3 years) general surgery research residents from 4 academic medical centers in Boston, MA. RESULTS: Survey response rate was 35.3% (36/102 residents). About 22 of 36 residents (61.1%) felt that their clinical aptitude decreased during the research years, whereas 33 of 36 (91.7%) reported reduced surgical skills. When reflecting on their re-entry to residency, former research residents reported feeling anxious and less confident (3.84/5 on a 1-5 Likert scale) as well as being below the expected level of clinical performance (3.42/5). Most of them (12 of 17; 70.6%) reported that it took up to 6 months, whereas 5 of them (29.4%) up to 12 months to feel at the expected level. When compared to nonmoonlighting residents, those who moonlighted often and operated during moonlighting, denied a decrease in clinical and surgical skills, and reported less anxiety, higher confidence, and a quicker return to the expected level of performance. Interventions proposed for improving their clinical re-entry included individualized development plans for 3 months before returning to clinical training, established curriculum for clinical work throughout the research years, clinical preceptorships throughout the research years, and simulation curriculum throughout the research years. CONCLUSIONS: General surgery residents feel that their clinical and surgical skills decreased during the research years, leading to anxiety and lack of confidence when returning to residency. Therefore, comprehensive interventions are needed to improve the reentry of the research residents into clinical training.

RESUMEN

Background: The spatial accuracy of microsurgical manipulations is one of the critical factors in successful surgical interventions. The purpose of this study was to create a low-cost, high-fidelity, and easy-to-use simulator for microsurgical skills training, which can be made by residents themselves at home. Methods: In response to the COVID-19 pandemic, we created a device for spatial accuracy microsurgical skills training and implemented it in our resident's training program. We propose a design for basic and advanced models. The simulator consisted of commonly available products. Results: A low-cost, durable, and high-fidelity basic model has been developed at a total cost of <10 dollars per unit. The model allows trainees to practice the critical microsurgical skills of tool targeting in a home-based setting. Conclusion: The developed device can be assembled at an affordable price using commercially available materials. Such simulation models can provide valuable training opportunities for microsurgery residents.

RESUMEN

Background: Burn care has long been an integral part of the scope of plastic surgery, but the time allocated to exposure for plastic surgery residents is under threat due to the range of sub-specialities competing for their time. As part of the Competence by Design approach to plastic surgical training, residents are provided with a list of 52 "Entrustable professional activities' (EPA's) to ensure that core skills and knowledge are acquired. Methods: This survey, distributed via email using a link to Survey MonkeyTM, sought to determine which EPA's were available for completion by plastic surgeons in training during the burn rotation at a major academic burn centre in Canada. Via investigator consensus, 26 of the 52 EPA's were included for assessment; the remaining 26 were not regarded as relevant to the burn centre rotation and therefore better acquired elsewhere. Results: Thirty two residents who underwent a burn rotation between 1 January 2015 and 31 December 2021 completed the anonymous survey. Seventeen of the 26 EPA's evaluated were judged by more than 75% of respondents as being readily amenable to completion during the burn rotation. Most of these EPA's relate to the comprehensive care of patients with acute burn injuries, the management of an in-patient plastic surgery service, and associated quality improvement processes. Residents who completed rotations less than three months in duration had less opportunity to complete a further 8 EPA's in comparison to those who had longer rotations, especially with respect to the care of patients undergoing complex wound care and burn reconstruction. Conclusions: In addition to threatening seamless service delivery at burn centres, reduced resident exposure to the burn rotation may compromise the delivery of burn care in the community. The results of this survey refute any argument that the burn service is a "low yield" rotation from an EPA acquisition perspective.

Historique: Les soins aux grands brûlés font partie intégrante de la chirurgie plastique depuis longtemps, mais le temps alloué à y exposer les résidents en chirurgie plastique est menacé en raison de l'éventail de surspécialités. Dans le cadre de l'approche de compétence par conception à la formation en chirurgie plastique, les résultats reçoivent une liste de 52 « activités professionnelles confiables ¼ (APC) pour assurer qu'ils acquièrent les compétences et le savoir de base. Méthodologie : Ce sondage, distribué par courriel grâce à un lien vers la plateforme Survey MonkeyMD, visait à déterminer quelles APC étaient offertes aux chirurgiens plastiques en formation pendant leur rotation dans un grand centre universitaire pour grands brûlés du Canada. Par consensus des chercheurs, 26 des 52 APC ont été incluses dans l'évaluation. Les 26 autres n'ont pas été considérées comme pertinentes pour la rotation au centre pour grands brûlés, mais mieux à même d'être acquises ailleurs. Résultats:  Au total, 32 résidents qui ont participé à une rotation auprès des grands brûlés entre le 1er janvier 2015 et le 31 décembre 2021 ont rempli le sondage anonyme. Selon plus de 75% d'entre eux, 17 des 26 APC évaluées peuvent facilement être effectuées pendant la rotation auprès des grands brûlés. La plupart de ces APC portent sur les soins complets aux patients atteints de brûlures aiguës, la gestion d'un service de chirurgie plastique aux patients hospitalisés et les processus d'amélioration de la qualité qui s'y associent. Les résidents qui ont effectué leur rotation en moins de trois mois avaient moins l'occasion d'effectuer huit APC de plus par rapport à ceux qui avaient vécu des rotations plus longues, particulièrement à l'égard des soins des plaies complexes aux patients et de la reconstruction après leurs brûlures. Conclusions : En plus de menacer la prestation harmonieuse des services dans les centres pour grands brûlés, la moins grande exposition des résidents à la rotation des grands brûlés peut compromettre la prestation des soins aux grands brûlés dans la communauté. Les résultats de ce sondage réfutent toute prétention selon laquelle les services aux grands brûlés est une rotation « à faible rendement ¼ selon le point de vue de l'acquisition des APC.

RESUMEN

BACKGROUND: Assessment of orthopaedic surgery trainees is traditionally based on subjective evaluation by faculty. The recent push for value-based health care has placed a premium on improving patient outcomes. As a result, surgical training evaluations for orthopaedic trainees are evolving to include more objective measures to evaluate competency. PURPOSE: To develop and subsequently demonstrate the efficacy of a novel surgical skills assessment for orthopaedic sports medicine fellows. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A team of 14 fellowship-trained orthopaedic sports medicine surgeons developed objective scoring rubrics for anterior cruciate ligament reconstruction (ACLR) and rotator cuff repair (RCR) using a modified Delphi process. Rubrics were designed based on 10 surgical steps with a grading scale (1-5) based on core competencies with a maximum summative score of 50. Fourteen orthopaedic fellows across a regionally diverse group of sports medicine-accredited fellowship programs were invited to complete both an ACLR and RCR in a surgical skills laboratory at the beginning and end of their fellowship year. Individual surgical steps, overall performance, and total procedure time were evaluated by a single sports medicine surgeon for both sessions. RESULTS: Thirteen of 14 fellows completed both pre- and post-fellowship assessments. For the ACLR procedure, the pre-fellowship mean summative score was 25.4 (SD, 4.4) and the post-fellowship mean summative score was 38.6 (SD, 4.1), which was a statistically significant improvement (P < .001). For the RCR procedure, the pre-fellowship mean summative score was 26.6 (SD, 5.4) and the post-fellowship mean summative score was 38.8 (SD, 4.3), which was also a statistically significant improvement (P < .001). The mean time to completion for the ACLR procedure was 82.3 minutes (SD, 4.3 minutes) pre-fellowship, which improved to 69.7 minutes (SD, 11.6 minutes) post-fellowship (P = .002). The mean time to completion for the RCR procedure was 85.5 minutes (SD, 5.0 minutes) pre-fellowship, which improved to 76.4 minutes (SD, 7.0 minutes) post-fellowship (P < .001). CONCLUSION: This surgical skills program represents the first standardized and reproducible instrument for the evaluation of 2 arthroscopic sports medicine procedures in the United States. Orthopaedic sports medicine fellows improved significantly in aggregate over their fellowship year with regard to the ACLR and RCR. The described program has the potential to serve as both a training tool and formal orthopaedic sports medicine fellow assessment.

RESUMEN

BACKGROUND: The purpose of this study was to examine the association between video gaming experience, spatial cognition, and laparoscopic surgical skills in a cohort of 50 medical students. METHOD: Participants were assessed for video gaming experience, spatial cognition, and laparoscopic skills. The number of hours played per week was also recorded. Structural equation modeling was used to determine the relationship between these variables. RESULTS: Our findings revealed that video gaming experience and spatial cognition exerted a positive influence on laparoscopic skills. Interestingly, students who excessively indulged in video games without concomitant improvements in spatial cognition experienced a negative impact on their laparoscopic skills. CONCLUSIONS: These findings underscore the potential of video gaming as a tool for improving surgical skills, but also highlight the potential downsides of excessive gaming. The positive correlation between gaming and surgical skills suggests that video games could be integrated into surgical education. Future research should focus on identifying specific video games that effectively promote visuospatial skills as well as determining the optimal balance between gaming and traditional surgical training.

RESUMEN

CONTEXT: Health simulation is a recognized educational method for teaching and validating surgical procedural skills. The latter requires the development of adapted assessment tools, reaching different validity criteria. The aim of this study was to validate a multimodal assessment tool for a complex skin suturing exercise, combining a manual knot, an intradermal linear suturing and a needle holder tied knot. METHODOLOGY: The suturing exercise was realized on a synthetic skin model by voluntary participants after having obtained their written consent, including 9 postgraduate medical students, 40 surgical residents of different levels of experience, and a group of 9 senior surgeons. The multimodal assessment tool (MAT) combined a checklist, a speed score and a global rating scale. Each exercise was scored by two evaluators. Medical students' performances were filmed anonymously so that they could be scored iteratively. Content validity was tested through a satisfaction questionnaire randomly completed by participants. RESULTS: The MAT was considered relevant or very relevant by 98% of the participants, with a better appreciation for the checklist than for the global rating scale. Internal consistency was strong with a Cronbach α coefficient at 0.78, and a good correlation between the results of the checklist and the global rating scale (r=0.79, P<0.0001). The MAT showed continuous improvement in mean scores from 34.4±3.6 for novices to 47.4±2.5/50 points for experts, passing through three intermediate levels groups, and allowed for significant discrimination between groups. The MAT was reliable, with a coefficient of correlation set at 0.88 for intra-observer reliability, and 0.72 for inter-observer reliability. On sub score analysis, the global rating scale and the speed score better discriminated between groups than the checklist, the latter moreover showing slightly lower reliability than the global rating scale. CONCLUSION: Despite its banality in any surgeon's practice and the fact that it is taught from the 2nd cycle of medical studies, suturing and its technical components have rarely been the subject of publications dedicated to the validation of specific assessment tools. Hence, this work on the MAT and its sub scores made it possible to validate them on many validity and reliability criteria. They can therefore be proposed to surgical teachers for evaluating a complex suturing exercise, with a checklist that is easier to use even for novices and a global rating scale showing better discrimination capacity.

RESUMEN

The objective of this study is to compare automated performance metrics (APM) and surgical gestures for technical skills assessment during simulated robot-assisted radical prostatectomy (RARP). Ten novices and six experienced RARP surgeons performed simulated RARPs on the RobotiX Mentor (Surgical Science, Sweden). Simulator APM were automatically recorded, and surgical videos were manually annotated with five types of surgical gestures. The consequences of the pass/fail levels, which were based on contrasting groups' methods, were compared for APM and surgical gestures. Intra-class correlation coefficient (ICC) analysis and a Bland-Altman plot were used to explore the correlation between APM and surgical gestures. Pass/fail levels for both APM and surgical gesture could fully distinguish between the skill levels of the surgeons with a specificity and sensitivity of 100%. The overall ICC (one-way, random) was 0.70 (95% CI: 0.34-0.88), showing moderate agreement between the methods. The Bland-Altman plot showed a high agreement between the two methods for assessing experienced surgeons but disagreed on the novice surgeons' skill level. APM and surgical gestures could both fully distinguish between novices and experienced surgeons in a simulated setting. Both methods of analyzing technical skills have their advantages and disadvantages and, as of now, those are only to a limited extent available in the clinical setting. The development of assessment methods in a simulated setting enables testing before implementing it in a clinical setting.

RESUMEN

BACKGROUND: Simulation and video-based assessment (VBA) offer residents the opportunity to develop operative skills while ensuring patient safety. This study aims to determine whether simulation training can predict residents' operative performance, focusing on the gastrojejunal (GJ) anastomosis during robotic pancreatoduodenectomy. METHODS: Twenty-seven general surgery residents completed simulated robotic GJ drills and subsequently performed GJs in the operating room (OR). Both simulated and intraoperative performances were video recorded and retrospectively assessed by two blinded graders using the Objective Structural Assessment of Technical Skills (OSATS) scale, time to completion, and occurrence of errors. Intraoperative GJ OSATS scores were compared in cases with and without Clinically Relevant Delayed Gastric Emptying (CRDGE). Statistical analysis was performed using Spearman's rho, Chi-square, and Kruskal-Wallis tests. RESULTS: For simulated GJs, the median OSATS score was 29 (IQR 27-33), time to completion was 30 min (IQR 27-35), and 11 cases had at least one error. Intraoperative GJs had a median OSATS of 30 (IQR 27-31), time to completion of 41 min (IQR 36-51), and errors occurred in nine cases. The OSATS score on the simulated GJs demonstrated a significant positive correlation to the OSATS score on the operative GJs (r = 0.74; p < 0.001) and less time to completion (r = - 0.68; p < 0.001). A shorter simulated GJ completion time significantly correlated with a higher intraoperative OSATS score (r = - 0.52; p < 0.01). Residents with at least one error in the simulated GJs had lower OSATS scores and higher times intraoperatively. Those cases with CRDGE had significantly lower intraoperative OSATS scores than those without CRDGE. CONCLUSION: Performance on a simulated robotic GJ environment is a robust predictor of OR GJ performance, demonstrating predictive validity. VBA of residents' operative GJ performance is associated with the presentation of CRDGE. Simulation-based training may be crucial to optimizing surgical outcomes before operating on patients.

RESUMEN

PURPOSE: To increase the number of medical students or residents who want to become surgeons, we must evaluate our program that recruits new young surgeons. METHODS: We planned surgical training programs for medical students and residents that we named the MANGOU (Miyazaki Advanced New General surgery Of University) training project in the Department of Surgery, Miyazaki University, Japan. From January 2016 through December 2022, we asked trainees who attended this training to complete questionnaires to evaluate their interest in surgery, confidence in surgical skills, and training. Scoring of the questionnaire responses was based on a 5-point Likert scale, and we evaluated this training prospectively. RESULTS: Among the 109 trainees participating in this training, 61 answered the questionnaires. Two participants found the training boring, but 59 (96.7%) enjoyed it. All of them answered "Yes" to wanting to participate in the next training. Respective pre- and post-training scores were as follows: confidence in surgical skills, 2.2 ± 1.0 and 3.0 ± 1.0 (p < 0.0001); interest in surgery, 4.2 ± 0.8 and 4.4 ± 0.5 (p = 0.0011); and willingness to become surgeons, 3.9 ± 0.7 and 4.1 ± 0.6 (p = 0.0011). All scores rose after MANGOU training. CONCLUSION: We planned MANGOU surgical wet lab training for medical students and residents that aimed to educate and recruit new surgeons. After joining the MANGOU training, the trainees' anxiety about surgery was reduced, their confidence in performing surgical procedures improved, they showed more interest in surgery, and they increased their motivation to become surgeons.

RESUMEN

Background: Few studies have studied the efficacy of using immersive virtual reality (iVR) to teach surgical skills, especially by using real-world iVR recordings rather than simulations. This study aimed to investigate whether viewing 360° iVR instructional recordings produces greater improvements in basic suturing skills of students without prior medical training, beyond traditional methods like reading written manuals or watching 2D instructional videos. Materials and methods: This was a partially blinded randomized cohort study. 44 pre-university students (aged 17) were randomized equally to either the written instruction manual, 2D instructional video, or iVR recordings. All students first watched a silent 2D demonstration video of the suturing task, before attempting to place three simple interrupted sutures on a piece of meat as a baseline. The time taken for the first attempt was recorded. Students were then given an hour to train using their allocated modality. They attempted the suturing task again, and timings were re-recorded. Four blinded surgically-trained judges independently assessed the quality of the stitches placed both pre and post-intervention. One-way analysis of variance tests (ANOVAs) and independent two-sample t-tests were used to determine the effect of training modality on improvements in suturing scores and time taken to complete suturing from pre to post-training. Results: For suturing scores, the iVR group showed significantly larger score improvements than the Written Manual group (p = 0.031, Cohen's D = 0.92), while this iVR advantage was less pronounced when compared with the 2D Video group (p = 0.16, Cohen's D = 0.65). Similarly for time taken to complete suturing, the iVR group had significantly larger time improvements than the Written Manual group (p = 0.045), although this difference was less robust compared to the 2D Instructional Video group (p = 0.34). Conclusion: This study demonstrates that iVR training using real-world 360° instructional recordings produced significantly greater training gains in suturing scores and efficiency compared to reading written text. iVR training also led to larger training gains in both outcome measures than viewing 2D instructional videos, although the differences between them did not reach statistical significance.

RESUMEN

INTRODUCTION: Since the integration of the intern year into urology residencies, programs are mandated to introduce fundamental skills to junior residents. Our goal was to assess the impact of one such program: the 2023 New York Section of the AUA (NYS-AUA) EMPIRE (Educational Multi-institutional Program for Instructing REsidents) Boot Camp. METHODS: Junior urology residents from all 10 NYS-AUA institutions attended a free EMPIRE Boot Camp on June 9, 2023. The seminar covered procedural skills including urethral catheterization, cystoscopy, renal and bladder ultrasound, transrectal prostate ultrasound with biopsy, and an introduction to robotics/laparoscopy. Sessions focused on urologic emergencies and postoperative scenarios. Participants completed questionnaires before, immediately after, and 6 months post course, assessing comfort with procedures and overall program quality using a 5-point Likert scale and free text responses. t Tests compared pre and immediate/6-month post scores. RESULTS: Forty junior residents, along with faculty and resident instructors from all 10 NYS-AUA programs, participated. Of the 40 trainees, 35 (87.5%) completed pre- and immediate post-boot camp surveys, while 23 (57.5%) responded to the 6-month follow-up survey. Ratings showed significant improvement in comfort with basic urologic technical skills for 13 out of 14 domains (93%) immediately after the course and at the 6-month mark. Attendees reported notably higher comfort levels in managing obstructive pyelonephritis (P = .003) and postoperative complications (P = .001) following didactic sessions. CONCLUSIONS: A skills-based, free collaborative urology boot camp for junior residents is feasible and can be effective. Trainees reported improved comfort performing certain technical skills and managing urologic emergencies both immediately after the course and at 6 months of follow-up.

RESUMEN

BACKGROUND: This study investigated the perceptions and performance of medical students regarding their engagement and learning of a knot-tying skill presented in an online demonstration format due to the emergency remote measures that accompanied COVID-19 restrictions. METHODS: Final-year undergraduate medical students were invited to view an online demonstration of a one-handed knot-tying skill and practice the skill using common household items. They recorded their attempts and uploaded them onto the Flipgrid application. Completed attempts were scored using an adapted Objective Structured Assessment of Technical Skill (OSATS) validated tool. We used a mixed-methods sequential explanatory design; data regarding students' engagement was gathered via a short questionnaire, and a Focus Group Discussion (FGD) was conducted to understand their learning experiences better. Descriptive statistics such as proportions and percentages were used to summarize categorical variables and median for continuous variables. Each video attempt was scored independently by two surgeons; reliability was determined using intraclass correlation; statistical tests were conducted at a 5% level of significance. Responses to open-ended survey questions and qualitative data from the FGDs were analysed using thematic analysis. RESULTS: Seventy-one students participated in the exercise. Most students (91.5%) expressed confidence in their ability to perform the skill and were able to follow the steps in the video demonstration (83.1%). Median number of times needed to practice before video submission was 7.0 (Interquartile range [IQR] 5.0-10.0). Using the adapted OSATS tool; median scores on student attempts were 19.0 out of 21 (IQR: 17.0-20.0) for Assessor 1 and 18.0 out of 21 (IQR: 17.0-20.0) for Assessor 2, and overall scores showed good reliability between assessors based on intraclass correlation (0.86, 95% CI 0.79-0.90, p < 0.001). Qualitative insights from the students' experiences in learning the skill were generally positive; it was a practical, experiential learning process and they valued the social aspects of learning via Flipgrid. Challenges expressed related to the need for in-person training and formal feedback on how to improve their technique. Suggestions to improve their learning included a request for an interactive session with immediate feedback on attempts, and being able to practice with a friend who would assist with videoing. CONCLUSION: Basic knot-tying can be taught with acceptable efficiency and student satisfaction using online methods with items available at home.

RESUMEN

BACKGROUND: Because the cases are quite scarce, we aimed to review cases of foreign body impaction penetrating the neck through the esophagus to analyze the characteristics of these cases. The open surgery skills of the surgeon, the treatment procedure and the surgeons' experience in the rare diseases were analyzed. METHODS: We collected and analyzed all cases from 2015-2020 in our hospital. Surgical skills and procedures for fasting and anti-infection treatment were reviewed retrospectively. Follow-up was telephone communication. RESULTS: Our series included 15 cases. Tenderness in the pre-cervical site was a physical sign for screening. Thirteen cases underwent a lateral neck open surgery with the incision including the left side of neck and only two cases were incised from the right side of the neck. Pus was found 3 days after the impaction in one case, the shortest time observed in our series. The esophageal laceration was only sutured primarily in 5 cases (33.33%) among all fifteen cases. After sufficient drainage (average more than 9 days), antibiotic treatment and fasting (normally 2-3 weeks), patients gradually began to switch to solid foods from fluids after complete blood counts and confirmations from esophageal radiography result. No severe complications occurred, and all the patients have no swallowing dis-function and recovered well. CONCLUSION: Surgery should be performed as soon as possible after impaction. Lateral neck approach surgery and the therapeutic procedure described in this article are safe and effective treatments.

RESUMEN

Robot-Assisted Minimally Invasive Surgery (RAMIS) marks a paradigm shift in surgical procedures, enhancing precision and ergonomics. Concurrently it introduces complex stress dynamics and ergonomic challenges regarding the human-robot interface and interaction. This study explores the stress-related aspects of RAMIS, using the da Vinci XI Surgical System and the Sea Spikes model as a standard skill training phantom to establish a link between technological advancement and human factors in RAMIS environments. By employing different physiological and kinematic sensors for heart rate variability, hand movement tracking, and posture analysis, this research aims to develop a framework for quantifying the stress and ergonomic loads applied to surgeons. Preliminary findings reveal significant correlations between stress levels and several of the skill-related metrics measured by external sensors or the SURG-TLX questionnaire. Furthermore, early analysis of this preliminary dataset suggests the potential benefits of applying machine learning for surgeon skill classification and stress analysis. This paper presents the initial findings, identified correlations, and the lessons learned from the clinical setup, aiming to lay down the cornerstones for wider studies in the fields of clinical situation awareness and attention computing.

RESUMEN

OBJECTIVE: Three-dimensional (3D) endoscopy has been developed to provide depth perception to allow for improved visualisation during otolaryngology surgery. We conducted a systematic review to determine the surgical safety and efficacy of 3D endoscopy in comparison to two-dimensional (2D) endoscopy in performing otolaryngology procedures, and the role of 3D endoscopy as a training tool for novice otolaryngology surgeons. METHODS: Primary studies were identified through MEDLINE, Embase and Web of Science databases, which were searched for articles published through June 2022 that compared the outcomes of 2D and 3D endoscopy in otolaryngology surgical procedures or otolaryngology-relevant simulations. Candidate articles were independently reviewed by two authors. RESULTS: A total of 18 full-text articles met inclusion criteria for this study. In clinical trials (n = 8 studies, 362 subjects), there were no significant differences in performance time, intraoperative or postoperative complications with 3D endoscopes when compared to 2D. In simulation studies (n = 10 studies, 336 participants), 3D endoscopes demonstrated a decreased error rate (n = 5 studies) and shorter performance time (n = 3 studies). Studies also reported improved depth perception (n = 14 studies) and visualisation preference (n = 5 studies) with 3D over 2D systems. The 3D systems were found to have a shorter learning curve and better manoeuvrability among novice surgeons. CONCLUSION: 3D endoscopy showed equivalent safety and efficacy compared to 2D endoscopy in otolaryngology surgery. The improved depth perception and performance for novices using 3D endoscopes suggests the technology may be superior to 2D endoscopes as a training tool for otolaryngology surgeons.

RESUMEN

Background: Replantation represents a treatment option for patients with severed finger pulps. However, in some cases, replantation is a challenging task. Case presentation: We report a successful case of finger pulp reconstruction of the ring finger using free flaps from a nonreplantable index finger in a spare-parts procedure. A 43-year-old worker accidentally injured the index, middle and ring fingers of his left hand on a machine turntable. The severed index and middle fingers and the distal pulp of the ring finger could not be replanted in situ due to extensive contusion of blood vessels and soft tissues. After vascular and nerve anastomosis, a free skin flap isolated from the nonreplantable index finger was transplanted to the wound of the distal pulpal defect of the ring finger. The flap survived completely postoperatively. Six months after the operation, only a slight deformity of the ring finger was observed. Moreover, sensation of the digit recovered well. Conclusions: Spare-part surgery is a surgical approach that effectively saves and utilizes tissue that would otherwise be discarded in cases of severe limb trauma. This idea may be applied to treatment of severe injuries to multiple fingers. Additionally, in the process of tissue transplantation and repair, attention should be given to protecting the tissue in the recipient area to avoid damage to the original undamaged tissue structure, which can adversely affect healing and recovery of the tissue.

RESUMEN

Much surgery in sub-Saharan Africa is provided by non-specialists who lack postgraduate surgical training. These can benefit from simulation-based learning (SBL) for essential surgery. Whilst SBL in high-income contexts, and for training surgical specialists, has been explored, SBL for surgical training during undergraduate medical education needs to be better defined. From 26 studies, we identify gaps in application of simulation to African undergraduate surgical education, including lack of published SBL for most (65%) World Bank-defined essential operations. Most SBL is recent (2017-2021), unsustained, occurs in Eastern Africa (78%), and can be enriched by improving content, participant spread, and collaborations.
