RESUMEN
Objective: To correlate the utility of the Fundamentals of Laparoscopic Surgery (FLS) manual skills program with the Objective Structured Assessment of Technical Skills (OSATS) global rating scale in evaluating operative performance. Methods: The Asian Urological Surgery Training and Educational Group (AUSTEG) Laparoscopic Upper Tract Surgery Course implemented and validated the FLS program for its usage in laparoscopic surgical training. Delegates' basic laparoscopic skills were assessed using three different training models (peg transfer, precision cutting, and intra-corporeal suturing). They also performed live porcine laparoscopic surgery at the same workshop. Live surgery skills were assessed by blinded faculty using the OSATS rating scale. Results: From March 2016 to March 2019, a total of 81 certified urologists participated in the course, with a median of 5 years of post-residency experience. Although differences in task time did not reach statistical significance, those with more surgical experience were visibly faster at completing the peg transfer and intra-corporeal suturing FLS tasks. However, they took longer to complete the precision cutting task than participants with less experience. Overall OSATS scores correlated weakly with all three FLS tasks (peg transfer time: r=-0.331, r 2=0.110; precision cutting time: r=-0.240, r 2=0.058; suturing with intra-corporeal knot time: r=-0.451, r 2=0.203). Conclusion: FLS task parameters did not correlate strongly with OSATS globing rating scale performance. Although FLS task models demonstrated strong validity, it is important to assimilate the inconsistencies when benchmarking technical proficiency against real-life operative competence, as evaluated by FLS and OSATS, respectively.
RESUMEN
OBJECTIVE: To compare characteristics of Urogynecology training and number of "Incontinence and Pelvic Floor" cases logged between OB/GYN residencies affiliated and those not affiliated with Urogynecology fellowships. DESIGN: A retrospective descriptive analysis was performed of OB/GYN residency programs, their Urogynecology training, and association with Urogynecology fellowship programs during the 2023-2024 academic year. Program websites for ACGME-accredited OB/GYN residency programs were reviewed to determine availability, timing, and length of Urogynecology training. ACGME data for "Incontinence and Pelvic Floor" cases were analyzed by training year and association with Urogynecology fellowship programs from the 2012-2013 to 2022-2023 academic year. Data was analyzed using SPSS. SETTING: This research was conducted at Harbor-UCLA Medical Center. PARTICIPANTS: None. INTERVENTIONS: None RESULTS: Information was obtained for 85.9% of programs. Nearly all (97.0%) had dedicated Urogynecology rotations, and 64.4% had rotations in > 1 year of training. Association with Urogynecology fellowship did not affect the availability of Urogynecology training overall nor the overall number of rotations. Urogynecology rotations occurred most often in the third (PGY3) year of residency, though 43.6% of programs had training for junior (PGY1, PGY2) residents. Residencies with associated Urogynecology fellowships were more likely to have a rotation for PGY2 residents and for junior residents overall. From 2012-2023, the number of "Incontinence and Pelvic Floor" cases declined by 36.3%, with trainees at residencies not affiliated with Urogynecology fellowships logging more cases than those at a fellowship-affiliated residency. CONCLUSION: While the majority of OB/GYN residencies have dedicated Urogynecology training, most rotations are for senior residents. Training programs associated with Urogynecology fellowships are more likely to expose junior residents to the field, but their trainees log fewer "Incontinence and Pelvic Floor" cases overall. Earlier exposure may enrich surgical training and help residents prepare for their career, whether in Urogynecology or as a generalist.
RESUMEN
We know of few studies in the international scientific literature that specifically address the evaluation of surgical and clinical progress among physicians undergoing specialist training in maxillofacial surgery. Identifying a reliable tool to accurately assess both theoretical knowledge and surgical skills of trainees is essential. The primary aim of this study therefore was to design a comprehensive assessment tool that is capable of evaluating both the theoretical and practical skills of physicians undergoing specialist training in maxillofacial surgery. The methodology employed aims to ensure fairness and effectiveness in skills development, thereby optimising training activities. To meet this need, an evaluation and self-assessment test was developed for maxillofacial surgery trainees at the Ospedali Riuniti of Ancona. Data collection involved digitally administered evaluations and self-assessment tests focused on maxillofacial traumatology, based on AO trauma surgery references. Data were processed into graphs which revealed a progressive learning trend following an initial adjustment phase, leading to optimal outcomes in both clinical and surgical domains. The evaluation and self-assessment test proved to be a valuable learning tool with which to gauge advancements in clinical and surgical skills among maxillofacial surgery residents.
RESUMEN
OBJECTIVES: To develop the use of Thiel soft embalmed human cadavers (TeC) in open radical cystectomy (ORC) training for the first time, to investigate the effect of cadaveric training on surgical trainees' technical skills/performance and to determine how trainees perceive the use of cadaveric workshops. METHODS: A 3-day hands-on workshop was organised. Ten trainees performed ORC on five TeC, supervised by five experts. Feedback from trainees and mentors was evaluated on a five-point Likert scale. All procedures were completed in a fully equipped surgical environment and complied with the principles outlined in the Declaration of Helsinki. RESULTS: The workshop participants evaluated the anatomical and manipulation characteristics of the TeC as similar to real-life conditions. The colour and consistency of the urethra and ureter differed little from those in live patients. The trainees stated that the TeC were beneficial for learning the stages of ORC and urinary diversion (UD), while their self-confidence increased. In terms of realism, all steps of radical cystectomy (RC) were rated 4 out of 5 or higher on the Likert scale by both trainees and faculty. CONCLUSIONS: The use of TeC for RC und UD was perceived as favourable by trainees and faculty. The TeC demonstrated a surprising ability to mimic real-life anatomy and represent a new and effective surgical training tool.
RESUMEN
BACKGROUND: The Royal Australasian College of Surgeons (RACS) recently instituted cultural safety and cultural competency as its 10th competency with formalized cultural safety training yet to be instituted. Wananga are Indigenous Maori teaching institutions that can be used contemporarily for cultural safety training. METHODS: In 2022, surgical registrars based at Taranaki Base Hospital (TBH) held in-hospital wananga ranging from 1 to 3 h focussed on cultural safety, professionalism and wellbeing. This study explores the perspectives of these registrars who attended wananga using a Kaupapa Maori aligned methodological stance and interpretive phenomenological analysis. RESULTS: Twenty-six wananga were held from March 22nd 2022 to January 30th 2023. Six registrars provided their perspectives with four major themes emerging from their stories including: cultural safety; unity; time, place and person; and a new era. Registrars valued the wananga which was scheduled for Friday afternoons after daily clinical duties. Wananga facilitated unity and understanding with registrars being able to reflect on the context within which they are practicing - describing it as a new era of surgical training. 'Time' was the biggest barrier to attend wananga however, the number of wananga held was testament to the commitment of the registrars. CONCLUSIONS: Regular wananga set up by, and for, surgical registrars cultural safety development is feasible and well subscribed in a rural or provincial NZ setting. We present one coalface method of regular cultural safety training and development for surgical registrars and trainees in NZ.
RESUMEN
BACKGROUND: Traditional surgical training and further education has historically involved long working hours and hands-on experience within the framework of a teacher-apprentice relationship; however, changes in regulatory policy in the USA and subsequently in Switzerland and the European Union from 2003, led to restrictions in the working hours of medical residents. As a result the traditional method of surgical training "see one, do one, teach one" has come under scrutiny, prompting a search for alternative training methods beyond the confines of the operating theater. OBJECTIVE: This publication highlights the possibilities and limitations associated with the use of virtual reality (VR) and gamification in surgical training and further education. It examines the ability of these technological resources to enhance the effectiveness and engagement of medical residents and the feasibility of incorporating them into the surgical training curriculum. MATERIAL AND METHODS: The study was based on a literature search for current developments in surgical training, VR and gamification. Furthermore, various studies and projects that investigated the use of VR and gamification in medical training and further education were analyzed. RESULTS AND DISCUSSION: In this investigation it could be shown that the use of VR reduces the perioperative risks and improves the training environment and learning. The use of gamification also increases the motivation and engagement of the medical residents. As a result the quality of medical education can be improved by the fusion of VR and gamification.
RESUMEN
The increasing complexity and difficulty of surgical procedures have led to a rise in medical errors within clinical settings in recent years. Gastrointestinal diseases, in particular, present significant medical challenges and impose substantial economic burdens, underscoring the urgent need for experiential, high-fidelity gastrointestinal surgical training tools. This study leverages patient-specific computed tomography (CT) and magnetic resonance imaging (MRI) data, combined with 3D printed manufacturing, to develop hydrogel organ models with tunable performance and tissue-mimicking softness. These properties are achieved by regulating the freeze-thaw cycles, cross-linking agents, and the concentration of incorporated antibacterial nanoparticles in DN hydrogels. Through the application of indirect 3D printing and the "sacrificial material method", we successfully fabricate organ tissues such as the stomach, intestines, and blood vessels with high precision. In ex vivo surgical training demonstrations, these tissue-like soft hydrogels provide an effective platform for preoperative simulation and surgical training in digestive surgery, accommodating various surgical procedures and accurately simulating intraoperative bleeding. The development of advanced bionic organ models with specific and tunable characteristics based on DN hydrogels is poised to significantly advance surgical training, medical device testing, and the reform of medical education.
RESUMEN
INTRODUCTION: Nonampullary duodenal adenocarcinoma (NDA) accounts for approximately 5% of all gastrointestinal cancers. Complete surgical resection (R0) with regional draining lymph node removal is mandatory as treatment to potentially cure nonampullary duodenal cancer or to achieve long-term survival. METHODS: According to existing literature, minimally invasive surgery has been reported to be safe and oncologically equivalent in pancreaticoduodenectomy for pancreatic and duodenal cancer. We describe a fully laparoscopic approach for the left-side adenocarcinoma of the duodenum "left-side" is defined with reference to the mesenteric vessels (III-IV segment). RESULTS: For the first time in literature, this multimedia paper describes a fully laparoscopic complete resection (R0) of the left side of the duodenum (III-IV segment) with locoregional lymph node resection. The main steps of the procedure are described using the concept of the critical view of safety. Reconstruction of intestinal continuity was ensured by full intracorporeal anastomosis. CONCLUSIONS: Through the tips and indications presented in this article, we supply a guide to the minimally invasive approach and increase operating surgeons' familiarity with such a complex procedure.
RESUMEN
Virtual reality (VR) integration into surgical education has gained immense traction by invigorating skill-building in ways that are unlike the traditional modes of training. This systematic review unites current literature relevant to VR in surgical education to showcase tool transferability, and subsequent impact on knowledge acquisition, skill development, and technological innovation. This review followed the PRISMA guidelines and included three databases. Among the 1926 studies that were screened, 31 studies met the inclusion criteria. ChatGPT assisted in generating variables for data extraction, and the authors reached unanimous consensus on 13 variables that provided a framework for assessing VR attributes. Surgical simulation was examined in 26 studies (83.9%). VR applications incorporated anatomy visualization (83.9%), procedure planning (67.7%), skills assessment (64.5%), continuous learning (41.9%), haptic feedback (41.9%), research and innovation (41.9%), case-based learning (22.6%), improved skill retention (19.4%), reduction of stress and anxiety (16.1%), and remote learning (12.9%). No instances of VR integration addressed patient communication or team-based training. Novice surgeons benefited the most from VR simulator experience, improving their confidence and accuracy in tackling complex procedural tasks, as well as decision-making efficiency. Enhanced dexterity compared to traditional modes of surgical training was also notable. VR confers significant potential as an adjunctive teaching method in plastic and reconstructive surgery (PRS). Studies demonstrate the utility of virtual simulation in knowledge acquisition and skill development, though they lack targeted approaches for augmenting training related to collaboration and patient communication. Given the underrepresentation of PRS among surgical disciplines regarding VR implementation in surgical education, longitudinal curriculum integration and PRS-specific technologies should be further investigated.
RESUMEN
BACKGROUND: The main barriers to the broad implementation of pediatric minimally invasive surgery (MIS) are technological, technical, and epistemological barriers, as well as the rarity of certain pathologies. These issues are presumed to be more significant in low- and middle-income countries. This study aimed to identify and analyze the factors limiting the diffusion and implementation of pediatric MIS in Brazil. METHODS: A nationwide cross-sectional survey was conducted via an online questionnaire in Brazil from January 2022 to July 2022. The sample was taken by convenience from the population of pediatric surgeons in Brazil. A total of 187 surgeons were included. The collected data were divided into three sections to evaluate technological, technical, and epistemological limitations to pediatric MIS implementation. RESULTS: Although 85% of the participants had previous training, a lack of adequate training was identified as a significant limiting factor, particularly among those who had taken only short courses (42.3% vs. 64.3%, p = 0.033). Only 14% of the participants reported performing MIS for major pediatric procedures. With respect to intracorporeal suturing, 38.1% of the surgeons with extensive training considered it a limiting factor compared with 60.7% (p = 0.029) of those without prior training. Among those without previous training, 61% cited a lack of financial support or encouragement from their department as the reason. Additionally, 65% of the surgeons considered the lack of basic instruments a limiting factor. Although 95% of the participants agreed that simulation training is indispensable, pediatric surgery fellowship programs in Brazil do not include a standardized curriculum or mandatory training in MIS, and only 47% reported providing training space for their current fellows. CONCLUSION: A combination of technological, technical, and epistemological barriers hinders the implementation of pediatric MIS. Despite its limitations, this study serves as a foundational guide for future analysis and overcoming the identified barriers.

Endoscopic submucosal dissection (ESD) requires skills that the vast majority of endoscopists do not possess. ESD be broken down into component skills and at least three of the necessary skill sets can be taught separately. In the United States most trainees initially participate in half- or full-day courses that utilize ex vivo and in vivo animal models and the great majority learn these advanced skills in the clinical setting. We describe a comprehensive training over a well-defined period using ex vivo porcine or bovine large bowel models. There are five components or modules that make up the training program: (1) bowel wall injections in ex vivo tissue, (2) inanimate figure tracing model to teach scope control, (3) ESD in plastic tube with window cutout over which square of ex vivo tissue is placed, (4) ESD in ex vivo porcine or bovine large bowel, and (5) mucosal wound closure. The authors are in the midst of training a group of residents, fellows, and young attendings using this approach. This approach has not been vetted yet; however, the preliminary results are promising.
RESUMEN
Introduction: While many studies have explored surgeons' personal and professional identities separately, our study is the first to examine intersecting female surgical identities. We explore intersecting surgical identities constructed by self and others (colleagues and patients) within two healthcare systems and their perceived impacts answering the research question: How do female surgeons' constructed identities intersect, and what influences do those intersections have on their surgical lives? Methods: We employed qualitative methodology drawing on semi-structured biographical narrative interviews underpinned by social constructionism. We employed intersectionality theory as an analytical lens. We adopted maximum variation sampling to identify diverse participants, including 38 surgeons (29 female; 9 male), 9 non-surgical colleagues (8 female, 1 male), and 13 patients of female surgeons (7 female, 6 male). Our 29 female surgeons also included six who had transitioned out of surgery. We analyzed the dataset using a five-step Framework Analysis approach. We captured talk about identities, as well as identity talk (constructions of identity through participants' talk). Findings: Multiple intersecting personal (not just gender) and professional identities were constructed and reported to have multiple impacts on female surgeons' lives (including their education, training, and success). We present intersecting identities and their impacts relating to gender through four primary intersections: (a) gender + ethnic identities; (b) gender + parenthood identities; (c) gender + age identities; and (d) gender + professional identities (namely carer, competent, mentor/mentee, role model and leader). Our findings particularly highlight the challenges experienced by female surgeons of color, who are mothers, who are younger and/or who are leaders, illustrating diversity in women's experiences beyond that of gender alone. Finally, we found unexpected insights into male surgeons and fatherhood. Discussion: Intersectionality theory offered a novel analytical lens to extend existing knowledge on female surgical identities. Further research is warranted exploring intersecting identities of female surgeons of color, younger female surgeons, and male surgeons who are fathers, as well as identities unexplored in this study (e.g., diverse sexualities). We need to raise awareness of intersecting identities and their impacts in surgery, as well as providing training, allyship, and policy revision that is sensitive to intersectionality.
RESUMEN
BACKGROUND: . Mitral transcatheter edge-to-edge repair (m-TEER) is a minimally invasive procedure for treating mitral regurgitation (MR). m-TEER is a highly technical procedure, and a steep learning curve needs to be overcome for operators to ensure optimal patient outcomes and minimise procedural complications. Training via online simulation and observation of procedures is not sufficient to establish operator confidence; thus, advanced hands-on training modalities need to be explored and developed. METHODS: . In this study, a novel anatomical simulator for m-TEER training was evaluated in comparison to a standard model. The proposed simulator resembled the anatomical features of the right and left atrium, left ventricle and mitral valve apparatus. Participants in the questionnaire (n = 18) were recruited across 4 centres in London with (n = 8) and without (n = 10) prior experience in m-TEER. Participants were asked to simulate procedures on both an idealised, routinely used simulator and the newly proposed anatomical model. The questionnaire was designed to assess (i) participants' confidence before and after training and (ii) the realism of the model in the context of the m-TEER procedure. The results of the questionnaires were collected, and statistical analysis (t-test) was performed. RESULTS: . Both models were equally beneficial in increasing operator confidence before and after the simulation of the intervention (P = 0.43). However, increased confidence after training with the anatomical model was recorded (P = 0.02). Participants with prior experience with m-TEER therapy were significantly more confident about the procedure after training with the anatomical model than participants who had no prior experience (P = 0.002). On average, all participants thought that the anatomical model was effective as a training simulator (P = 0.013) and should be integrated into routine training (P = 0.015)). Participants with experience thought that the anatomical model was more effective at reproducing the m-TEER procedure than the idealised model (P = 0.03). CONCLUSIONS: . This study showed how a more realistic simulator can be used to improve the effectiveness of m-TEER procedural training. Such pilot results suggest planning future and large investigations to evaluate improvements in clinical practice.
RESUMEN
Background A surgical fellowship allows both additional training as well as maintenance of surgical skills while searching for a steady job. As the presence of fellows usually does not results in a measurably higher productivity, fellowshipsmay be considered a form of disguised unemployment. The aim of this study is to evaluate the career flow of a surgical trainee to a staff position and to determine the number of surgeons working on temporary basis within the general surgery workforce in Flanders.Methods All surgeons graduated in Flanders between 2000 and 2022 were invited to fill out a web-based survey concerning their current and past employment. Reminders were sent out after 2 and 4 weeks. Statistical analysis was performed with SPSS version 27.0 (IBM Inc., Chicago, IL, USA.)Results Response rate was 64% (292/457) with 76% of respondents currently working as surgeons, 14% (38) as fellows and 10% working outside the surgical domain. Eighty-two percent of current fellows graduated in 2019 or later. Thirty-one percent of surgeons graduated in 2019 are still working as fellows. For surgeons graduated in 2020, 2021 and 2022 this is 45%, 80% and 90% respectively. Compared to staff surgeons the number of additional training years (2,8 ± 1,0 vs 2,2 ± 1,3; p = 0,009). and the number of applications (6,6 ± 5 vs 3,3 ± 3; p < 0,001) is significantly higher for current fellowsConclusion This study shows that disguised unemployment is present in the general surgical community in Flanders. The status of "fellow" should be incorporated in calculations concerning future needs of the surgical workforce in order to prevent open unemployment.
RESUMEN
Background: The optimal training program to transform a new resident into a competent and capable surgeon is constantly evolving. Competency-based evaluation represents a change in mindset from quantitative or chronologic metrics for graduate readiness. As surgery becomes more specialized, more dependent on technology, and more public, we must continue to improve our ability to pass on technical skills. Approaching surgery in a component-based fashion enables even the most complex operation to be broken down into smaller sets of steps that range the entire spectrum of complexity. Treating an operation through the lens of its components, emphasizing stepwise forward progression in a trainee's experience, may provide a way to train competent surgeons more efficiently. Current case-logging products do not provide adequate granularity to apply this methodology. Methods: Application design relied on the involvement of local surgeons from all specialties and subspecialties related to general surgical training. Individual interviews with multiple experts in each field were used to generate a list of most commonly performed operations. Once a consensus was reached, the same surgeons were queried on what they felt were the core steps that make up each operation. This information was utilized to create a novel mobile application which enables the user to record cases by date, attending surgeon, specific operation, and which portions of the operation they were able/allowed to perform. Conclusion: Component-based case logging through the Logix application may be a useful adjunct as we continue to implement competency-based surgical training. Future investigation will assess user experience and compare subjective and objective metrics of training progression between the Logix application and currently utilized products. The information provided by the application stands to benefit not just trainees, but educators, training programs, and regulatory bodies. Key message: Component-based case logging via a novel mobile application stands to increase the efficiency of surgical training and more effectively assess trainee competency.
RESUMEN
PURPOSE: The resection of lymph nodes/neck dissection is a typical part of the surgical treatment of head and neck malignancies. The aim of this study was to compare subcutaneous closure using single knotted, braided suture (VicrylTM, standard arm) with continuous self-locking, monofilament barbed suture (V-LocTM, experimental arm). METHODS: Neck Lock was a randomized clinical trial at a single tertiary referral center. It was conducted from 2016 till 2022 with a follow-up period of 3 months. Assessment of safety and aesthetic outcome was double-blinded. 68 patients were randomized after application of exclusion criteria. Subcutaneous wound closure was performed in an intrapatient randomized fashion for suture technique. The primary endpoint was the duration of subcutaneous sutures. Wound healing and scar formation were recorded at multiple postoperative intervals as secondary endpoints. RESULTS: The median age was 61 years, 89.7% were male. 92.6% suffered from a squamous cell carcinoma. There was a significant difference in median subcutaneous suture time (p = 0.024) between the experimental (6:11 ± 2:30 min) and standard (7:01 ± 2.42 min) arms. There was no significant difference in safety when assessing adverse events (AEs). At least one AE occurred in 14.7% vs. 5.9%, for barbed and smooth sutures respectively (p = 0.16). CONCLUSION: For neck dissection of head and neck malignancies, subcutaneous wound closure with self-locking sutures offers significant time savings over the single knot technique with similar safety and aesthetic results. TRIAL REGISTRATION INFORMATION: The trial was registered with WHO acknowledged primary registry "German Clinical Trials Register" under the ID DRKS00025831 ( https://drks.de/search/de/trial/DRKS00025831 ).
RESUMEN
BACKGROUND: Temporal bone dissection is overwide recognized as an ideal training method for otologic surgeons. The knowledge of temporal bone anatomy and especially of the course of infratemporal facial nerve is pivotal in practice. The 3D exoscope is an innovative and promising tool, that was recently introduced in ear surgery. METHODS: A high-definition 3D exoscope (3D VITOM®) mounted on the VERSACRANETM holding system (Karl Storz) was used to perform two temporal bone dissection, with the aim to study the anatomy of infratemporal facial nerve. The 3D endoscope (TIPCAM®1 S 3D ORL, Karl Storz) was used in combination to provide a close-up high-quality view and to provide a different angle of view on fine anatomical relationships. RESULTS: The high-definition 3D exoscope allowed to conduct the dissection with high quality visualization and to share the same surgical field with trainees. Moreover, it showed a high interchangeability with the 3D endoscope. CONCLUSIONS: 3D 4 K Exo-endoscopic temporal bone dissection seems to have benefits in terms of educational purpose, especially concerning anatomy understanding. The superiority in teaching value of this tool should be further investigated in cohort studies.
RESUMEN
Introduction: To highlight the importance of hands-on experiences and mentorship in shaping the future workforce of specialized medical professionals via a Neurosurgery Training Camp. Methods: Responses of the questionnaire regarding the Neurosurgery Training Camp organized by Bursa Uludag University's Faculty of Medicine and the Turkish Neurosurgery Academy were reviewed retrospectively. A one-day program was organized to introduce neurosurgery to medical students. During the camp, the students participated in interactive presentations delivered by faculty members, had lunch together, became acquainted with neurosurgical tools and technologies, and performed interventions. With pre and postworkshop questionnaire, student's expectations and thoughts about camp was evaluated. Results: Forty-one students from 10 medical schools, spanning every year of study, attended the camp. Approximately 39% of the attendees (n = 16) were women and 61% (n = 25) were men. The post-workshop survey results demonstrated that 73% of the students (n = 30) were inclined to pursue a career in neurosurgery after the camp, 21.9% (n = 9) remained undecided, and 4.8% (n = 2) chose not to pursue neurosurgery. Feedback from the post-workshop questionnaire highlighted that all students perceived the camp as beneficial in providing insights into their future careers and aiding in making a decision regarding their career paths. Discussion: The neurosurgical training camp effectively inspired and educated medical students about the discipline of neurosurgery. Furthermore, the camp effectively altered the career aspirations and perceptions of neurosurgery among the participating students.
RESUMEN
OBJECTIVE: This review surveys the literature on sensorimotor challenges impacting performance in laparoscopic minimally invasive surgery (MIS). BACKGROUND: Despite its well-known benefits for patients, achieving proficiency in MIS can be challenging for surgeons due to many factors including altered visual perspectives and fulcrum effects in instrument handling. Research on these and other sensorimotor challenges has been hindered by imprecise terminology and the lack of a unified theoretical framework to guide research questions in the field. METHOD: We conducted a systematic survey of the MIS literature, focusing on studies investigating sensorimotor challenges affecting laparoscopic performance. To provide a common foundation for cross-study comparisons, we propose a standardized taxonomy that distinguishes between different experimental paradigms used in the literature. We then show how the computational motor learning perspective provides a unifying theoretical framework for the field that can facilitate progress and motivate future research along clearer, hypothesis-driven lines. RESULTS: The survey identified diverse sensorimotor perturbations in MIS, which can be effectively categorized according to our proposed taxonomy. Studies investigating monitor-, camera-, and tool-based perturbations were systematically analyzed, elucidating their impact on surgical performance. We also show how the computational motor learning perspective provides deeper insights and potential strategies to mitigate challenges. CONCLUSION: Sensorimotor challenges significantly impact MIS, necessitating a systematic, empirically informed approach. Our proposed taxonomy and theoretical framework shed light on the complexities involved, paving the way for more structured research and targeted training approaches to enhance surgical proficiency. APPLICATION: Understanding the sensorimotor challenges inherent to MIS can guide the design of improved training curricula and inform the configuration of setups in the operating room to enhance surgeon performance and ultimately patient outcomes. This review offers key insights for surgeons, educators, and researchers in surgical performance and technology development.
RESUMEN
INTRODUCTION: The training box is an effective tool used by surgical trainees. Suturing training is the common method of practicing laparoscopic surgery; however, the cost of needles and threads for long-term practice remains a problem. In this study, we incorporated the original Japanese training for laparoscopic surgery by making an origami paper crane (laparoscopic origami training (LOT)) and evaluated its effect on the clinical results as a long-term practice. METHODS: LOT was performed using a single 7.5 × 7.5 cm origami paper in the training box of laparoscopic surgery. In the bench-top study, the total time required to make one paper crane was measured and evaluated, and a self-efficacy questionnaire was designed to analyze the efficacy of LOT. In clinical practice, we retrospectively compared two resident groups, one that had previously trained on LOT (trained group) and the other that did not (less-trained group), by analyzing the pneumoperitoneum time (PT) for 10 cases. RESULTS: After making paper cranes in approximately 100 cases, the making time was reduced to approximately 10 min. Long-term results analyzing up to 1500 cases revealed that in addition to shortening the time required to make a paper crane, the shape of the crane also improved. Consequently, the median PT was significantly shorter in the trained group than in the less-trained group (129.0 (62-287) versus 208.5 (127-343) min; p<0.001). CONCLUSION: LOT contributed to introducing safe laparoscopic surgery to residents and improved their laparoscopic outcomes. We believe that this is a useful practice methodology that can be recommended to general physicians who wish to practice laparoscopic surgeries.
