RESUMEN

BACKGROUND: There is a potential benefit on long-term outcomes following complete mesocolic excision (CME) for right-sided colon cancer when compared to conventional colectomy. This study aims to analyze the learning curve and short-term outcomes of laparoscopic CME with intracorporeal anastomosis (ICA) for right-sided colon cancer in the hands of experienced colorectal surgeons. METHODS: A two-center cohort study of consecutive patients undergoing right-sided colectomy from September 2021 to May 2022 at two tertiary colorectal centers in Denmark. Learning curves of surgical time were estimated using a cumulative sum analysis (CUSUM). RESULTS: A total of 61 patients were included. According to the CUSUM analysis, 32 cases were needed to obtain a peak in operative time, resulting in a decrease in time consumption (group 1/learning phase: 217.2 min [SD 53.6] and group 2/plateau phase 191.6 min [SD 45.1], p = 0.05). There was a nonsignificant reduction in the rates of severe surgical complications (Clavien-Dindo > 3) (13% vs. 7%, p = 0.67) between the two groups, while the length of hospital stay remained constant (median 3.0 days, interquartile range, IQR [2.0; 4.0]). CONCLUSION: The learning curve of laparoscopic CME with ICA for right-sided colon cancer demonstrated that 32 cases were needed to obtain a plateau phase expressed by operative time.

RESUMEN

BACKGROUND: Robot-assisted surgery is today well-implemented in many surgical specialties, but requires another skill set than laparoscopy. Most often, robot-assisted surgery is considered add-on to laparoscopic skills but very little is known about the transfer of skills. The aim of the study was to examine to what extent surgical skills are transferable between laparoscopic and robot-assisted surgery. METHODS: A systematic search was conducted in three databases (Ovid Medline, Embase, and Web of Science). Studies investigating transfer of skills between laparoscopy and robot-assisted surgery in either a phantom-based, simulation-based, animal model, or clinical setting were eligible for inclusion. Quality assessment was done using the Medical education research study quality instrument and educational New Ottawa Scale. RESULTS: Of 15,610 studies identified, 89 studies continued to full-text reading, and 37 studies were included. Four studies were found non-comparable and were left out of the results for the primary outcome. All 33 studies explored transfer from laparoscopy to robot-assisted surgery and 17 found a positive transfer whereas 15 did not. Only 11 studies explored transfer from robot-assisted surgery to laparoscopy, of which only three found a positive transfer. CONCLUSION: An almost equal number of publications found a positive transfer and no transfer from laparoscopic to robot-assisted surgery. Fewer studies explored the transfer from robot-assisted surgery to laparoscopy. Very little evidence supports that surgeons trained solely in robot-assisted surgery can perform laparoscopy. This must be considered in future training programs as robot-assisted surgery is expected to become the first-in-line modality for many future surgeons.

RESUMEN

BACKGROUND: Basic thoracic ultrasound is being used more frequently by clinicians in several settings due to its high diagnostic accuracy for many common causes of respiratory failure and dyspnoea. However, ultrasound examinations are operator-dependent, and sufficient competences are needed to obtain high sensitivity and specificity of examinations. Additionally, it is crucial for ultrasound operators to perceive the competence to interpret the images and integrate them into the patient history and other examinations. This study aims to explore and gather validity evidence for an objective structured clinical examination test of basic thoracic ultrasound competences and establish a pass/fail score. METHODS: An expert panel created the test which included two theoretical and five practical stations representing cases with different diagnoses that cause respiratory symptoms and which are possible to establish by basic thoracic ultrasound. Twenty-five participants with different levels of experience in basic thoracic ultrasound completed the test. Data of the test scores were used for item analysis, and exploring validity evidence was done according to Messick's framework which is recommended. The contrasting groups' standard setting method was used to establish a pass/fail score. RESULTS: The summarised internal consistency reliability was high with a Cronbach's alpha of 0.87. The novice group (n = 4) had a mean test score of 42 ± 10.1 points, the intermediate group (n = 8) scored 79.1 ± 8.1 points, and the experienced group (n = 13) 89.0 ± 6.2 points (one-way ANOVA, p < 0.001). A pass/fail score of 71 points was thus derived (maximum test score = 105 points). CONCLUSION: We developed a test for the assessment of clinical competences in basic thoracic ultrasound with solid validity evidence, and a pass/fail standard with no false positives or false negatives.

RESUMEN

OBJECTIVE: This systematic review aims to examine the use of standard-setting methods in the context of simulation-based training of surgical procedures. SUMMARY OF BACKGROUND: Simulation-based training is increasingly used in surgical education. However, it is important to determine which level of competency trainees must reach during simulation-based training before operating on patients. Therefore, pass/fail standards must be established using systematic, transparent, and valid methods. METHODS: Systematic literature search was done in 4 databases (Ovid MEDLINE, Embase, Web of Science, and Cochrane Library). Original studies investigating simulation-based assessment of surgical procedures with the application of a standard setting were included. Quality of evidence was appraised using GRADE. RESULTS: Of 24,299 studies identified by searches, 232 studies met the inclusion criteria. Publications using already established standard settings were excluded (N = 70), resulting in 162 original studies included in the final analyses. Most studies described how the standard setting was determined (N = 147, 91%) and most used the mean or median performance score of experienced surgeons (n = 65, 40%) for standard setting. We found considerable differences across most of the studies regarding study design, setup, and expert level classification. The studies were appraised as having low and moderate evidence. CONCLUSION: Surgical education is shifting toward competency-based education, and simulation-based training is increasingly used for acquiring skills and assessment. Most studies consider and describe how standard settings are established using more or less structured methods but for current and future educational programs, a critical approach is needed so that the learners receive a fair, valid, and reliable assessment.

RESUMEN

INTRODUCTION: Contrast-enhanced ultrasound is utilized in an increasing array of medical fields, including thoracic medicine. However, the technique is still relatively new and only sporadically mentioned in current guidelines and recommendations. The aim of this systematic review is to provide a literature overview and to critically appraise the current clinical applications of contrast-enhanced thoracic ultrasound (CETUS). MATERIALS AND METHODS: A systematic literature search using major electronic databases and in accordance with PRISMA guidelines was performed. Studies with a primary focus on CETUS of thoracic disorders compared to a standard reference test were included. The QUADAS-2 tool was used for quality assessment of the studies. RESULTS: The search identified 43 articles: 1 randomized controlled study, 6 non-randomized controlled studies, 16 non-randomized non-controlled studies, 5 case series, 10 single case reports, and 5 animal studies. The overall risk of bias was judged to be high. Diagnostic accuracy measurements of noninvasive applications of CETUS were only reported in a few studies and they were too dissimilar for meta-analysis. Six studies compared CETUS-guided versus ultrasound-guided transthoracic needle biopsy of thoracic masses. They individually reported a significant increase in diagnostic accuracy in favor of CETUS guidance but were too heterogeneous for meta-analysis. CONCLUSION: The current literature on CETUS is overall heterogeneous with a few high evidence level studies, small study populations and a high risk of bias. CETUS-guided biopsy is the most frequent clinical application and increases diagnostic accuracy compared to ultrasound guidance by an average of 14.6 percentage points.

RESUMEN

Thoracic ultrasound is increasingly considered to be an essential tool for the pulmonologist. It is used in diverse clinical scenarios, including as an adjunct to clinical decision making for diagnosis, a real-time guide to procedures and a predictor or measurement of treatment response. The aim of this European Respiratory Society task force was to produce a statement on thoracic ultrasound for pulmonologists using thoracic ultrasound within the field of respiratory medicine. The multidisciplinary panel performed a review of the literature, addressing major areas of thoracic ultrasound practice and application. The selected major areas include equipment and technique, assessment of the chest wall, parietal pleura, pleural effusion, pneumothorax, interstitial syndrome, lung consolidation, diaphragm assessment, intervention guidance, training and the patient perspective. Despite the growing evidence supporting the use of thoracic ultrasound, the published literature still contains a paucity of data in some important fields. Key research questions for each of the major areas were identified, which serve to facilitate future multicentre collaborations and research to further consolidate an evidence-based use of thoracic ultrasound, for the benefit of the many patients being exposed to clinicians using thoracic ultrasound.

RESUMEN

INTRODUCTION: As ultrasound becomes more accessible, the use of point-of-care ultrasound examinations performed by clinicians has increased. Sufficient theoretical and practical skills are prerequisites to integrate thoracic ultrasound into a clinical setting and to use it as supplement in the clinical decision-making. Recommendations on how to educate and train clinicians for these ultrasound examinations are debated, and simulation-based training may improve clinical performance. OBJECTIVES: The aim of this study was to explore the effect of simulation-based training in thoracic ultrasound compared to training on healthy volunteers. METHOD: A total of 66 physicians with no previous experience in thoracic ultrasound completed a training program and assessment of competences from November 2018 to May 2019. After a theoretical session in ultrasound physics, sonoanatomy, and thoracic ultrasound, the physicians were randomized into one of three groups for practical training: (1) simulation-based training, (2) training on a healthy volunteer, or (3) no training (control group). Primary outcome was difference in the clinical performance score after the training period. RESULTS: Using a multiple comparison, ANOVA with Bonferroni correction for multiplicity, there was no statistical significant difference between the two trained groups' performance score: 45.1 points versus 41.9 points (minimum 17 points, maximum 68 points; p = 0.38). The simulation-based training group scored significantly higher than the control group without hands-on training, 36.7 points (p = 0.009). CONCLUSIONS: The use of simulation-based training in thoracic ultrasound does not improve the clinical performance score compared to conventional training on healthy volunteers. As focused, thoracic ultrasound is a relatively uncomplicated practical procedure when taught; focus should mainly be on the theoretical part and the supervised clinical training in a curriculum. However, simulation can be used instead or as an add-on to training on simulated patients.

RESUMEN

BACKGROUND: Clinical lung ultrasound (LUS) is a fast bedside diagnostic tool which can assist clinicians in decisions regarding the treatment and monitoring of patients with respiratory symptoms. LUS training and education differ widely, and is often done in a clinical setting, with potential risks for patients if decisions are made based on the wrong interpretations. No clear guidelines or recommendations for objective and standardized assessment of LUS skills exist, and those that do are often based on a fixed time-frame or an arbitrary number of examinations performed; this does not ensure adequate competencies. OBJECTIVES: The study aimed to develop and gather validity evidence for a practical, simulation-based test in LUS. METHODS: Nine cases were developed in collaboration with 3D Systems Healthcare, Littleton, CO, USA, representing the most common diagnosis and sonographic findings in patients with respiratory symptoms. Thirty-six participants with different levels of competence in LUS, completed the test. The participants were divided into groups, i.e., novices, intermediates, and experienced, according to their experience with LUS, the number of examinations they had performed, and any research they had conducted. Their answers were used for item analyses. RESULTS: The intraclass correlation coefficient, Cronbachs' α, was 0.69 summarized, and there was a statistically significant difference (p < 0.001) between the novices and the trained participants (intermediates and experienced). A pass/fail score of 16 points was calculated according to the contrasting-groups method. CONCLUSION: We developed a test for the assessment of clinical competencies in LUS. The test proved solid validity evidence, and a pass/fail standard without any false-negatives, and only 2 explained false-positives.

RESUMEN

BACKGROUND: Thoracic ultrasound (TUS) has a high diagnostic accuracy for many common pulmonary diseases, but theoretic knowledge in sonographic physics, thoracic anatomy and physiology, and sonopathologic patterns is required to develop competence. OBJECTIVES: The aims of the study were to develop and gather validity evidence for a theoretical test in TUS and to establish a pass/fail standard. METHODS: Content was provided based on expert interviews, leading to the creation of 113 initial multiple-choice question (MCQ) items. Consensus was reached on 92 proceeding items through a Delphi process, and items were presented to physicians with different knowledge and experience in TUS. Answers were used for item statistics in order to select the items with the most optimal item discrimination and difficulty (i.e., level I items) to be included in the final test. Mean scores of the novice, intermediate and experienced groups were compared, and a pass/fail score was established using the contrasting groups' standard setting method. RESULTS: Item statistics revealed 38 level I items, of which 30 were selected to be included in the final test. The internal consistency was high (Cronbach's alpha = 0.88). Differences in mean scores were 8.6 points (p < 0.001), 6.3 points (p = 0.01), and 14.9 points (p < 0.001) between novices and intermediates, intermediates and experienced, and novices and experienced, respectively. A pass/fail standard of 20 points was established. CONCLUSION: The established MCQ test can distinguish between physicians with different levels of competence in TUS and enables an objective, evidence-based approach for assessing the theoretical knowledge of trainees undergoing an educational programme in TUS.

RESUMEN

BACKGROUND: The use of simulators in a training programme for technically challenging procedures has the advantages of lowering the risk of patient complications while helping the trainees with the initial part of their learning curve. OBJECTIVES: The aim of this study was to perform a systematic review of simulation-based training in flexible bronchoscopy and endobronchial ultrasound (EBUS). METHODS: We identified 1,006 publications in the PubMed database and included publications on flexible bronchoscopy below the carina and EBUS involving hands-on simulation-based training. Publications were excluded if they were written in languages other than English, if paediatric airways were involved or if they were not journal articles. The screening process was performed by 2 individuals, and a third reviewer made the final decision in case of disagreement. RESULTS: We included 30 publications. The studies included participants of varying experience and most commonly used a virtual reality simulator as a training modality. Assessment of the participants' skills was based on simulator metrics or on an assessment tool. Some studies included performance on patients for assessment of the operator after training on a simulator. CONCLUSIONS: Simulation-based training was demonstrated to be more efficient than the traditional apprenticeship model. Physical models and virtual reality simulators complement each other. Simulation-based education should be based on a mastery learning approach and structured as directed self-regulated learning in a distributed training programme.

RESUMEN

OBJECTIVE: Operator skills are essential for thoracic ultrasound (TUS) to ensure diagnostic accuracy. Immersive virtual reality (IVR) has shown potential within medical education but never for assessment of TUS skills. This study was aimed at developing an IVR test for assessing TUS skills, gathering validity evidence and establishing a pass/fail score. METHODS: An expert panel developed a test based on the TUS protocol by the European Respiratory Society (ERS), including a tutorial and two clinical cases (pleural effusion and interstitial syndrome), using an IVR platform (VitaSim, Odense, Denmark). Four anterior, four lateral and six posterior zones were available for examination and decision of diagnosis. Each correct examination equaled one point. The contrasting groups' method was used to set a pass/fail score. RESULTS: Data were collected during the 2022 ERS Congress. We included 13 novices (N, experience: 0 TUS), 22 intermediates (I, 1-50 TUS) and 11 experienced clinicians (E, >50 TUS). Cronbach's α was 0.86. The total mean point scores in case 1 (C1) were (N) 5.0 ± 2.7, (I) 7.3 ± 2.4 and (E) 8.7 ± 1.3, and the scores in case 2 (C2) were (N) 4.5 ± 1.8, (I) 6.7 ± 2.3 and (E) 8.5 ± 2.1. Significant differences were found between N and I for C1 (p = 0.007) and C2 (p = 0.02), I and E for C1 (p = 0.04) and C2 (p = 0.019) and N and E for C1 (p < 0.001) and C2 (p < 0.001). The pass/fail score was 7 points in each case. CONCLUSION: We established an IVR test that can distinguish between operators with different TUS skills. This enables a standardized, objective and evidence-based approach to assessment of TUS skills.

RESUMEN

PURPOSE: Endophytic renal cancer treatment is a challenge. Due to difficulties in endophytic tumor visualization during surgical extirpation, image-guided percutaneous cryoablation (PCA) is an attractive alternative. The minimally invasive nature of PCA makes it favorable for comorbid patients as well as patients in which surgery is contraindicated. Oncological outcomes and complications after PCA of endophytic biopsy-proven renal cell carcinoma (RCC) were reviewed in this study. MATERIALS AND METHODS: Patients were included after a multidisciplinary team conference from January 2015 to November 2021. Inclusion criteria were endophytic biopsy-proven T1 RCC treated with PCA with one year of follow-up. Complications were reported according to the Cardiovascular and Interventional Radiological Society of Europe (CIRSE) classification system and the Clavien-Dindo classification (CDC) system. Major complications were defined as a grade ≥ 3 according to the CDC. RESULTS: Fifty-six patients were included with a total of 56 endophytic tumors treated during 61 PCA sessions. The median RENAL nephrometry score was 9 (IQR 2), and the mean tumor size was 25.7 mm (SD ± 8.9 mm). Mean hospitalization time was 0.39 (SD ± 1.1) days. At a mean follow-up of 996 days (SD ± 559), 86% of tumors were recurrence free after one PCA. No patients progressed to metastatic disease. According to the CIRSE classification, 10.7% (n = 6) had grade 3 complications, and 5.4% (n = 3) had CDC major complications. CONCLUSION: This study demonstrates that PCA of endophytic biopsy-proven T1 RCC is safe with few major complications and excellent local tumor control rates at almost three-year mean follow-up. LEVEL OF EVIDENCE 3: Retrospective cohort study.

RESUMEN

The Clinical Techniques, Imaging and Endoscopy Assembly is involved in the diagnosis and treatment of several pulmonary diseases, as demonstrated at the 2023 European Respiratory Society (ERS) International Congress in Milan, Italy. From interventional pulmonology, the congress included several exciting results for the use of bronchoscopy in lung cancer, including augmented fluoroscopy, robotic-assisted bronchoscopy and cryobiopsies. In obstructive lung disease, the latest results on bronchoscopic treatment of emphysema with hyperinflation and chronic bronchitis were presented. Research on using cryobiopsies to diagnose interstitial lung disease was further explored, with the aims of elevating diagnostic yield and minimising risk. For imaging, the latest updates in using artificial intelligence to overcome the increased workload of radiologists were of great interest. Novel imaging in sarcoidosis explored the use of magnetic resonance imaging, photon-counting computed tomography and positron emission tomography/computed tomography in the diagnostic work-up. Lung cancer screening is still a hot topic and new results were presented regarding incorporation of biomarkers, identifying knowledge gaps and improving screening programmes. The use of ultrasound in respiratory medicine is an expanding field, which was demonstrated by the large variety in studies presented at the 2023 ERS Congress. Ultrasound of the diaphragm in patients with amyotrophic lateral sclerosis and myasthenia gravis was used to assess movements and predict respiratory fatigue. Furthermore, studies using ultrasound to diagnose or monitor pulmonary disease were presented. The congress also included studies regarding the training and assessment of competencies as an important part of implementing ultrasound in clinical practice.

RESUMEN

This case presents CT-guided percutaneous cryoablation as a treatment option in a patient with oligometastatic breast cancer who previously had received standard-of-care treatment for metastatic breast cancer. Before cryoablation, the patient received two systemic lines of therapy, several surgeries and radiotherapy for oligometastatic disease. The cryoablation was performed in a single 7 mm subpleural oligometastatic lesion 42 months after diagnosis of metastatic breast cancer. It was performed without complications, and the patient experienced no complaints or discomfort after the procedure. A 3-month, 6-month, 9-month and 12-month follow-up fluorodeoxyglucose-positron emission tomography/CT scans showed no sign of disease progression.

RESUMEN

The case is presented of a woman in her 60s with renal cell carcinoma in a solitary kidney with normal renal function. Because of the solitary kidney status, the management strategy described in acknowledged guidelines was not possible. The patient was treated with standard first-line tyrosine kinase inhibitor followed by percutaneous CT-guided cryoablation. Before and after the procedure the patient had normal kidney function. The treatment resulted in local cancer control, but a bone metastasis developed in the thoracic part of the spine.

RESUMEN

Objectives: Using virtual reality (VR), students of radiography can practice acquisition and positioning of musculoskeletal radiographs and get immediate feedback on their performance within the simulator. The purpose of this study was to assess usability of a newly developed VR simulator and to explore self-perceived clinical readiness (SPCR) of radiography students before and after training acquisition of wrist radiographs in the VR simulator. Material and Methods: A prospective methodology was applied where the students (n = 10) estimated their own SPCR in regard to acquisition of wrist radiographs pre- and post-VR training. A questionnaire on usability, realism, and educational value of the simulator was answered post-VR training. Usability and SPCR scores were calculated. The student's paired t-test was applied to explore the impact of VR training on SPCR. Results: The students (90%) reported that the simulator was realistic and they thought that it could contribute to learning. The pre- and post-SPCR scores were 75 (95% confidence interval [CI]: 54-96) and 77 (95% CI: 59-95), respectively. There was no significant difference (P = 0.4574) between the pre- and post-SPCR scores. Conclusion: Results indicated that the concept of training acquisition and positioning of wrist radiographs in a VR simulator is feasible with positive feedback from the students. The SPCR scores improved slightly, although not statistically significant, after completion of the training session.

RESUMEN

Objectives: In the last decade, the incidence of renal cell carcinoma (RCC) has been rising, with the greatest increase observed for solid tumors. Magnetic resonance imaging (MRI) protocols and algorithms have recently been available for classifying RCC subtypes and benign subtypes. The objective of this study was to prospectively validate the MRI algorithm presented by Cornelis et al. for RCC classification. Material and Methods: Over a 7-month period, 38 patients with 44 renal tumors were prospectively included in the study and received an MRI examination in addition to the conventional investigation program. The MRI sequences were: T2-weighted, dual chemical shift MRI, diffusion-weighted imaging (DWI), and dynamic contrast-enhanced T1-weighted in wash-in and wash-out phases. The images were evaluated according to the algorithm by two experienced, blinded radiologists, and the histopathological diagnosis served as the gold standard. Results: Of 44 tumors in 38 patients, only 8 tumors (18.2%) received the same MRI diagnosis according to the algorithm as the histopathological diagnosis. MRI diagnosed 16 angiomyolipoma, 14 clear cell RCC (ccRCC), 12 chromophobe RCC (chRCC), and two papillary RCC (pRCC), while histopathological examination diagnosed 24 ccRCC, four pRCC, one chRCC, and one mixed tumor of both pRCC and chRCC. Malignant tumors were statistically significantly larger than the benign (3.16 ± 1.34 cm vs. 2.00 ± 1.04 cm, P = 0.006). Conclusion: This prospective study could not reproduce Cornelis et al.'s results and does not support differentiating renal masses using multiparametric MRI without percutaneous biopsy in the future. The MRI algorithm showed few promising results to categorize renal tumors, indicating histopathology for clinical decisions and follow-up regimes of renal masses are still required.

RESUMEN

Thoracic ultrasound has become a well-implemented diagnostic tool for assessment and monitoring of patients with respiratory symptoms or disease. However, ultrasound examinations are user dependent and sufficient competencies are needed. The European Respiratory Society (ERS) hosts a structured and evidence-based training programme in thoracic ultrasound. This study aimed to explore and discuss the self-reported activity and self-reported competency of the participants during the ERS course. Online surveys were sent to the training programme participants before the second part of the course (practical part of the course), and before and 3 months after the third part of the course (final certification exam). A total of 77 participants completed the surveys. The self-reported frequency of thoracic ultrasound examinations increased during the course, and in the final survey more than 90% of the participants used thoracic ultrasound on weekly basis. The self-reported competency (on technical execution of the thoracic ultrasound examination and overall competency) also increased. The ERS thoracic ultrasound training programme forms the basis of broad theoretical knowledge and sufficient practical skills that seem to lead to behavioural changes, whereby a large proportion of the participants implemented ultrasound in their clinical practice.
