Abstract

El propósito del presente estudio fue comprobar si el autotrasplante de células mesoteliales peritoneales en heridas de espesor total en ratas acelera y modifica el proceso de cicatrización cutánea normal, basándonos en la teoría de que las células mesoteliales provenientes de tejidos como el peritoneo, pleura o pericardio, son responsables de uno de los procesos de cicatrización más rápidos y sintetizan varios factores estimulantes y quimiotácticos de la cicatrización (causantes de las adherencias intraabdominales), además de que poseen la capacidad de diferenciarse en otras series celulares (plasticidad). Diseñamos un estudio experimental, analítico, longitudinal, prospectivo y comparativo, en el Laboratorio de Cirugía Experimental del Centro Médico ABC Observatorio, México D.F. (México). Se emplearon 15 ratas cepa Wistar, divididas en 2 grupos: Grupo I (n=5) en el que previa anestesia general, se extirparon 3 mm. de diámetro de piel de la región dorsal mediante técnica microquirúrgica y cierre por segunda intención; y Grupo II (n=10) en el que se realizó minilaparotomía con escisión de peritoneo parietal, cierre primario de la misma, escisión de piel de espesor total en región dorsal de 3 mm. de diámetro y colocación del autoinjerto peritoneal en la herida dorsal. En el análisis histológico se revisaron 6 variables: colágeno, fibroblastos, número de vasos, macrófagos, células inflamatorias y grado de retracción, para puntualizar integralmente el tipo y características de la cicatrización en ambos grupos. El análisis estadístico de datos se elaboró con Statistical Package of Social Sciences 17.0. Se realizó estadística descriptiva por medio de medidas de frecuencia, de tendencia central y de dispersión. Los resultados mostraron que los individuos del Grupo I presentaron mayor inflamación, fibrosis y retracción, datos compatibles con una fase proliferaría de cicatrización. En el Grupo II se encontró menor inflamación y fibrosis, mayor colágeno y datos compatibles con una fase de remodelación. En conclusión, el autotrasplante de células mesoteliales peritoneales en heridas de espesor total acelera el proceso de cicatrización cutánea normal en ratas ya que disminuye la inflamación, la fibrosis y aumenta el colágeno.The purpose of this study was to verify if the autologous peritoneal mesothelial cells in full thickness wounds on rats, speed up and adjust the normal skin healing process. Based on the theory that mesothelial cells from tissues such as peritoneum, pleura or pericardium, are responsible for one of the faster healing process and synthesize stimulating wound healing and chemotactical factors (hence the genesis of surgical adhesions), besides possessing the ability to differentiate into other cell series (plasticity). We designed a pilot, analytical, longitudinal, prospective and comparative study in the Laboratory of Experimental Surgery at The American British Cowdray Medical Center, Mexico City (México). Were used 15 Wistar rats which were divided into 2 groups: Group I (n = 5) where after general anesthesia, skin removed 3 mm in diameter with microsurgical technique in the back and was close by secondary intention; and Group II or experimental group (n = 10) where laparotomy was performed with excision of the parietal peritoneum and primary closure, excision of full thickness skin on the dorsal surface of 3mm diameter and peritoneal autograft placement on the dorsal wound. In histological analysis, were reviewed 6 variables: collagen, fibroblasts, number of vessels, macrophages, inflammatory cells and retraction, to point out fully the nature and characteristics of healing in both groups. For the statistical analysis we used Statistical Package for Social Sciences 17.0. The descriptive statistics was made using frequency measures of central tendency and dispersion. The results showed that the Group I rats, had increased inflammation, fibrosis and retraction, data support a proliferative phase of healing. In the Group II or experimental were found less inflammation and fibrosis, increased collagen and data consistent with a remodeling phase. In conclusion, we found that autologous peritoneal mesothelial cells in full thickness wounds accelerates the normal skin healing in rats by decreasing inflammation, fibrosis and increased collagen.

Abstract

El propósito del presente estudio fue comprobar si el autotrasplante de células mesoteliales peritoneales en heridas de espesor total en ratas acelera y modifica el proceso de cicatrización cutánea normal, basándonos en la teoría de que las células mesoteliales provenientes de tejidos como el peritoneo, pleura o pericardio, son responsables de uno de los procesos de cicatrización más rápidos y sintetizan varios factores estimulantes y quimiotácticos de la cicatrización (causantes de las adherencias intraabdominales), además de que poseen la capacidad de diferenciarse en otras series celulares (plasticidad). Diseñamos un estudio experimental, analítico, longitudinal, prospectivo y comparativo, en el Laboratorio de Cirugía Experimental del Centro Médico ABC Observatorio, México D.F. (México). Se emplearon 15 ratas cepa Wistar, divididas en 2 grupos: Grupo I (n=5) en el que previa anestesia general, se extirparon 3 mm. de diámetro de piel de la región dorsal mediante técnica microquirúrgica y cierre por segunda intención; y Grupo II (n=10) en el que se realizó minilaparotomía con escisión de peritoneo parietal, cierre primario de la misma, escisión de piel de espesor total en región dorsal de 3 mm. de diámetro y colocación del autoinjerto peritoneal en la herida dorsal. En el análisis histológico se revisaron 6 variables: colágeno, fibroblastos, número de vasos, macrófagos, células inflamatorias y grado de retracción, para puntualizar integralmente el tipo y características de la cicatrización en ambos grupos. El análisis estadístico de datos se elaboró con Statistical Package of Social Sciences 17.0. Se realizó estadística descriptiva por medio de medidas de frecuencia, de tendencia central y de dispersión. Los resultados mostraron que los individuos del Grupo I presentaron mayor inflamación, fibrosis y retracción, datos compatibles con una fase proliferaría de cicatrización. En el Grupo II se encontró menor inflamación y fibrosis, mayor colágeno y datos compatibles con una fase de remodelación. En conclusión, el autotrasplante de células mesoteliales peritoneales en heridas de espesor total acelera el proceso de cicatrización cutánea normal en ratas ya que disminuye la inflamación, la fibrosis y aumenta el colágeno.

Abstract

Continuous professional development (CPD) is crucial for physicians to maintain and enhance their skills. In response to the changing context of CPD and health care, this study applied a design thinking approach to transform and modernise the Royal College of Physicians and Surgeons of Canada's Maintenance of Certification (MOC) Program. A member-wide survey and co-design sessions with physicians, CPD leaders, and patient representatives were conducted, emphasising the importance of their insights and experiences. The data revealed key themes for the programme such as fostering meaningful learning, addressing barriers to CPD, supporting collaboration, and responding to the need for modern, flexible CPD delivery methods. Using "empathy", "define", "ideate", "prototype", and "test" phases, we continuously refined the MOC framework of CPD activities based on comprehensive user experiences and needs insights. The revised framework was iteratively prototyped and validated to ensure it was user-friendly and aligned with professional and regulatory requirements. The findings underscore the effectiveness of the design thinking approach in creating a dynamic, responsive MOC framework that supports CPD and meets the evolving needs of medical professionals. This approach not only demonstrates the effectiveness of design thinking but also the importance of engaging users in the development process, making them feel valued and integral to the transformation of the MOC Program., Competing Interests: All the authors disclose they were full-time staff or contractors with the Royal College of Physicians and Surgeons of Canada when this process occurred. No external funding was used for this process., (© 2024 Royal college of physicians and surgeons of Canada. Published by Informa UK Limited, trading as Taylor & Francis Group.)

Abstract

Background: Emerging technologies are being incorporated in surgical education. The use of such technology should be supported by evidence that the technology neither distracts nor overloads the learner and is easy to use. To teach chest tube insertion, we developed an e-learning module, as part of a blended learning program delivered prior to in-person hands-on simulation. This pilot study was aimed to assess learning effectiveness of this blended learning, and cognitive load and the usability of e-learning., Methods: The interactive e-learning module with multimedia content was created following learning design principles. In advance of the standard simulation, 13 first-year surgical residents were randomized into two groups: 7 received the e-learning module and online reading materials (e-learning group); 6 received only the online reading materials (controls). Knowledge was evaluated by pre-and post-tests; technical performance was assessed using a Global Rating Scale by blinded assessors. Cognitive load and usability were evaluated using rating scales., Results: The e-learning group showed significant improvement from baseline in knowledge ( P = .047), while controls did not ( P = .500). For technical skill, 100% of residents in the e-learning group reached a predetermined proficiency level vs 60% of controls ( P = .06). The addition of e-learning was associated with lower extrinsic and greater germane cognitive load ( P = .04, .03, respectively). Usability was evaluated highly by all participants in e-learning group., Conclusion: Interactive e-learning added to hands-on simulation led to improved learning and desired cognitive load and usability. This approach should be evaluated in teaching of other procedural skills., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Abstract

Abstract: Efforts to optimize continuing professional development (CPD) are ongoing and include advocacy for the use of clinician performance data. Several educational and quality-based frameworks support the use of performance data to achieve intended improvement outcomes. Although intuitively appealing, the role of performance data for CPD has been uncertain and its utility mainly assumed. In this Scholarly Perspective, the authors briefly review and trace arguments that have led to the conclusion that performance data are essential for CPD. In addition, they summarize and synthesize a recent and ongoing research program exploring the relationship physicians have with performance data. They draw on Collins, Onwuegbuzie, and Johnson's legitimacy model and Dixon-Woods' integrative approach to generate inferences and ways of moving forward. This interpretive approach encourages questioning or raising of assumptions about related concepts and draws on the perspectives (i.e., interpretive work) of the research team to identify the most salient points to guide future work. The authors identify 6 stimuli for future programs of research intended to support broader and better integration of performance data for CPD. Their aims are to contribute to the discourse on data advocacy for CPD by linking conceptual, methodologic, and analytic processes and to stimulate discussion on how to proceed on the issue of performance data for CPD purposes. They hope to move the field from a discussion on the utility of data for CPD to deeper integration of relevant conceptual frameworks., (Copyright © 2023 the Association of American Medical Colleges.)

Abstract

Background: Laparoscopic suturing (LS) is an essential technique required for a wide range of procedures, and it is one of the most challenging for surgical trainees to master. We designed and collected validity evidence for advanced LS tasks using an automated suturing device and evaluated the perceived educational value of the tasks., Methods: This project was a multicentre prospective study involving McGill University, University of Toronto (UofT), and Louisiana State University (LSU) Health New Orleans. Novice (NS) and experienced (ES) surgeons performed suturing under tension (UT) and continuous suturing (CS) tasks. ES performed the tasks twice to establish proficiency benchmarks, and they were interviewed to develop formative feedback tools (FFT). Participants were assessed on completion time, error, Global Operative Assessment of Laparoscopic Skills (GOALS), and FFT. Data were analyzed using descriptive and inferential statistical methods., Results: Twenty-seven participants (13 ES, 14 NS, median age 34 years; 85% male) completed the study. Eight were attending surgeons, 7 fellows, 4 PGY5, 5 PGY4, and 3 PGY3 (18 from McGill, 5 UofT, and 4 LSU). Comparing ES and NS, for UT task, ES had significantly greater task scores (570 [563-648] vs 323 [130-464], p value 0.00036) and GOALS scores (14 [13-16] vs 10 [8-12], p value 0.0038). Similarly, for CS, ES had significantly greater task scores (976 [959-1010] vs 785 [626-856], p value 0.00009) and GOALS scores (16 [12-17] vs 12.5 [8.25-15], p value 0.028). After FFTs were developed, comparing ES and NS, for both UT and CS tasks, ES had significantly greater FFT scores (UT 25 [24-26] vs 17 [14-20], p value 0.0016 and CS 30 [27-32] vs 22[17.2-25.8], p value 0.00061)., Conclusion: In conclusion, preliminary validity evidence was provided for the tasks. Once further validity evidence is established, incorporating the tasks into the training curricula could improve trainee skills and help to meet the need for better advanced suturing models., (© 2022.

Abstract

Background: Peer coaching has been associated with much higher rates of practice changes and new skill implementation compared to common used modalities but bilateral peer coaching structures where seniority is not a requirement to coach have not been studied. The purpose of this study was to implement and evaluate a reciprocal peer coaching pilot program for practicing surgeons to inform future coaching program design., Methods: A multicenter reciprocal peer surgical coaching program was designed according to the framework developed from previous studies by our group. The coach-coachee matching process was voluntary and autonomous. All participants received basic coaching skills training. Pairs were instructed to complete two coaching sessions, alternating between the coach or coachee role for each session. Data were collected through questionnaires and structured interviews., Results: Twenty-two participants enrolled in the pilot study and completed the coach training (88% enrollment rate). During the first wave of COVID-19, 12 participants withdrew. Of the five pairs that completed the program, three pairs were composed of general surgeons, one of orthopedic surgeons, and one ophthalmologic surgeon. Three sessions were conducted live in the OR, five virtually, and one involved an in-person discussion. Overall satisfaction with the program was high and all participants expectations were met. Participants were significantly more likely to predict "routinely" asking for feedback from their partner after study completion (6, 66%) compared to pre-intervention (p = 0.02)., Conclusion: This pilot study supports the feasibility of a peer coaching model for surgeons in practice that emphasized reciprocity and participant autonomy. These key elements should be considered when designing future coaching programs., (© 2022. The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.)

Abstract

Background: Telesimulation helps overcome limitations in time and local expertise by eliminating the need for the learner and educator to be physically co-located, especially important during COVID-19. We investigated whether teaching advanced laparoscopic suturing (ALS) through telesimulation is feasible, effective, and leads to improved suturing in the operating room (OR)., Methods: In this prospective feasibility study, three previously developed 3D-printed ALS tasks were used: needle handling (NH), suturing under tension (UT), and continuous suturing (CS). General surgery residents (PGY4-5) underwent 1-month of telesimulation training, during which an expert educator at one site remotely trained residents at the other site over 2-3 teaching sessions. Trainees were assessed in the three tasks and in the OR at three time points: baseline(A1), control period(A2), and post-intervention(A3) and completed questionnaires regarding educational value and usability of telesimulation. Paired t-test was used to compare scores between the three assessment points., Results: Six residents were included. Scores for UT improved significantly post-intervention A3(568 ± 60) when compared to baseline A1(416 ± 133) (p < 0.019). Similarly, scores for CS improved significantly post-intervention A3(756 ± 113) vs. baseline A1(539 ± 211) (p < 0.02). For intraoperative assessments, scores improved significantly post-intervention A3(21 ± 3) when compared to both A1(17 ± 4) (p < 0.018) and A2(18 ± 4) (p < 0.0008). All residents agreed that tasks were relevant to practice, helped improve technical competence, and adequately measured suturing skill. All residents found telesimulation easy to use, had strong educational value, and want the system to be incorporated into their training., Conclusion: The use of telesimulation for remotely training residents using ALS tasks was feasible and effective. Residents found value in training using the tasks and telesimulation system, and improved ALS skills in the OR. As the pandemic has caused a major structural shift in resident education, telesimulation can be an effective alternative to on-site simulation programs. Future research should focus on how telesimulation can be effectively incorporated into training programs., (© 2021.

Abstract

Background: Surgical peer coaching has been associated with high rates of practice change but remains largely unutilized. The purpose of this study was to survey surgeons internationally to investigate attitudes regarding peer coaching and to identify any international differences to inform the design of future coaching programs., Methods: Practicing surgeons in general surgery or related subspecialties were eligible to participate. Invitations to complete the survey were distributed through 13 surgical associations, social media, and personal e-mail invitations. Responses were obtained between June 1st and August 31st, 2020., Results: A total of 521 surveys were collected. The majority of participants practiced in North America (263; 50%) with remaining respondents from Asia (81; 16%), Europe (34;7%), South America (21; 4%), Africa (17; 3%), and Oceania (6; 1%). Duration of practice was equally distributed across 4 intervals (0-5 years; 6-15 years; 16-25 years; > 25 years). Respondents most frequently identified as general surgeons (290; 67%) and 325 (75%) were male. Awareness of peer coaching was reported by 275 (53%) respondents, with 197 (44%) never seeking formal feedback from peers. The majority of respondents (372; 84%) would be willing to participate in a peer coaching program, with monthly interactions the most desirable frequency reported (193; 51%). Coaching in the operating room was preferred by most participants (360; 86%). Few respondents (67; 14%) would accept coaching from someone unknown to them. Participants identified key coaching program elements as: feedback kept private and confidential (267; 63%); opportunity to provide feedback to the coach (247; 59%); personalized goal setting (244; 58%); and the option to choose one's own coach (205; 49%). The most commonly cited potential barrier to participation was logistical constraints (334; 79%)., Conclusion: This international survey of practicing surgeons demonstrated that peer feedback is rarely used in practice, but there is high interest and acceptance of the peer coaching model for continuous professional development. Findings regarding preferred program structure may be useful to inform the design of future peer coaching programs., (© 2021.

Abstract

Background: Continuous advancement of surgical skills is of utmost importance to surgeons in practice, but traditional learning activities without personalized feedback often do not translate into practice changes in the operating room. Peer coaching has been shown to lead to very high rates of practice changes and utilization of new skills. The purpose of this study was to explore the opinions of practicing surgeons regarding the characteristics of peer coaching programs, in order to better inform future peer coaching program design., Methods: Using a convenience sample, practicing general surgeons were invited to participate in focus group interviews. Allocation into groups was according to years in practice. The interviews were conducted using open-ended questions by trained facilitators. Audio recordings were transcribed and coded into themes by two independent reviewers using a grounded theory approach., Results: Of 52 invitations, 27 surgeons participated: 74% male; years in practice: < 5 years: 33%; 5-15 years: 26%; > 15 years: 41%. Three main themes emerged during coding: ideal program structure, motivations for participation, and barriers to implementation. For the ideal structure of a peer coaching program all groups agreed coaching programs should be voluntary, involve bidirectional learning, and provide CME credits. Live, in situ coaching was preferred. Motivations for coaching participation included: desire to learn new techniques (48%), remaining up to date with the evolution of surgical practice (30%) and improvement of patient outcomes (18%). Barriers to program implementation were categorized as: surgical culture (42%), perceived lack of need (26%), logistical constraints (23%) and issues of coach-coachee dynamics (9%)., Conclusion: Peer coaching to refine or acquire new skills addresses many shortcomings of traditional, didactic learning modalities. This study revealed key aspects of optimal program structure, motivations and barriers to coaching which can be used to inform the design of successful peer coaching programs in the future.

Abstract

Background: Simulation is widely used to teach and assess fundamental laparoscopic skills; however, program directors have reported that current simulation programs do not meet the needs for trainees and surgeons learning advanced laparoscopic procedures (ALP). The purpose of our study was to identify the key skills required to perform ALP, to serve as the basis to establish an advanced laparoscopic skills training program., Methods: Semi-structured interviews were conducted with attending surgeons, fellows, and senior residents in general surgery, gynaecology, and urology. The questions were developed through an iterative process using relevant literature, expert opinions, and in consultation with a qualitative researcher. Interviews were conducted in person, over the phone, or by videoconference, and inductive thematic analysis was performed., Results: 25 interviews were conducted with 16 attending surgeons and 9 fellows/residents from 9 institutions in Canada and USA. Twenty-one skills were identified to be important when performing ALP. The skills most commonly described by faculty were the following : (a) suturing, (b) dissection, (c) procedural expertise, (d) retraction and exposure, and (e) familiarity with relevant anatomy as viewed through the laparoscope. The skills most commonly described by trainees were the following: (a) suturing, (b) dissection, (c) procedural expertise, (d) trocar positioning, and (e) patient factors. There was a large difference between the importance the faculty attributed to the 'Retraction and Exposure' skill compared to the trainees., Conclusion: This study identified key skills that are important when performing ALP. In order to address the current needs of trainees/surgeons learning ALP, this work provides the building blocks for the development of an advanced laparoscopic surgery simulation program.

Abstract

Introduction: Despite recent changes to medical education, surgical training remains largely based on the apprenticeship model. However, after completing training, there are few structured learning opportunities available for surgeons in practice to refine their skills or acquire new skills. Personalized observation with feedback is rarely a feature of traditional continuing medical education learning. Coaching has recently been proposed as a modality to meet these educational gaps; however, data are limited, and few coaching programs presently exist. The purpose of this study is to summarize the characteristics of coaching programs for surgeons in practice including participant satisfaction, program outcomes, and barriers to implementation, in the published literature., Methods: A mixed studies systematic review was conducted according to PRISMA guidelines to identify all original studies describing or investigating coaching for practicing surgeons up to 06/2019. Quantitative analysis was used to summarize numerical data, and qualitative analysis using grounded theory methodology for descriptive data was used to summarize the results into themes across studies., Results: After identification of articles, 27 were included in the final synthesis. Twenty-six articles described execution of a coaching program. Programs varied widely with 18/26 focusing on teaching new skills, and the remainder on refinement of skills. Thematic analysis identified 2 major data categories that guided deeper analysis: outcomes of and barriers to coaching. Of the 16 (62%) programs that reported outcomes of coaching, 42% to 100% of participants reported changes in clinical practice directly associated with coaching. Positive satisfaction after completion of a program was reported by 82% to 100% of participants. Reported barriers to participating in a coaching program emerged along 3 main themes: logistical constraints, surgical culture, and perceived lack of need., Conclusions: Coaching for surgeons in practice is highly rated by participants and often results in clinical practice changes, while cultural and logistical issues were identified as barriers to implementation. A better understanding of these factors is required to guide coaching program development and implementation., (Copyright © 2020 Association of Program Directors in Surgery.

Abstract

Background: Excessive opioid prescribing after surgery has been recognised as a contributor to the current crisis of opioid addiction and overdose. Clinicians may potentially tackle this crisis by using opioid-free postoperative analgesia; however, the scientific literature addressing this approach is sparse and heterogeneous, thereby limiting robust conclusions. A scoping review was conducted to systematically map the extent, range, and nature of the literature addressing postoperative opioid-free analgesia., Methods: Eight bibliographic databases were searched for studies addressing opioid-free analgesia after a major surgery. We extracted the study characteristics, including design, country, year, surgical procedure(s), and interventions. Results were organised thematically according to surgical specialty and targeted phase of recovery: in hospital (early recovery, ≤24 h after operation; intermediate recovery, >24 h) and post-discharge (late recovery). Reporting was according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement for scoping reviews., Results: We identified 424 studies addressing postoperative opioid-free analgesia. The number of studies conducted in countries where the opioid crisis is primarily focused was remarkably low (USA, n=11 [3%]; Canada, n=5 [1%]). Many RCTs compared opioid-free vs opioid analgesia during hospital stay (n=117), but few targeted analgesia post-discharge (n=8). Studies were predominantly focused on procedures in orthopaedic, general, and gynaecological/obstetric surgery. Limited attention has been directed towards non-pharmacological pain interventions. We did not identify knowledge synthesis studies (i.e. systematic reviews and meta-analyses) focused on the comparative effectiveness of opioid-free vs opioid analgesia., Conclusions: Opioids remain a mainstay analgesic for managing pain after surgery, but alternative analgesia strategies should not be overlooked. This scoping review indicates numerous opportunities for future research targeting opioid-free postoperative analgesia.

Abstract

Background: Primary hyperparathyroidism is a disease characterised by the autonomous production of parathyroid hormone. The most common cause is an adenoma, followed by hyperplasia, and rarely carcinoma., Clinical Cases: Three cases are presented. The first case is associated with a brown tumour that was diagnosed as hyperplasia after study and surgery. The second case was related to pathological fractures, and a lower right adenoma 236 times bigger than a normal parathyroid was excised. The last case presented with abdominal pain and heartburn. Histopathology reported a carcinoma, which was removed using surgery en bloc. All patients have improved., Conclusion: Hyperparathyroidism symptoms are very difficult to identify and diagnose, thus a detailed and broad approach is needed when hyperparathyroidism is suspected., (Copyright © 2016 Academia Mexicana de Cirugía A.C.
