Training with the compactEASIE biologic endoscopy simulator significantly improves hemostatic technical skill of gastroenterology fellows: a randomized controlled comparison with clinical endoscopy training alone

BACKGROUND: The Erlangen Active Simulator for Interventional Endoscopy (EASIE) was introduced in 1997 for interventional endoscopy training. compactEASIE developed in 1998 is a modified, light-weight version of the original model. Objective evidence of the benefits of training with these models is limited. A randomized controlled study, therefore, was conducted to compare the effects of intensive 7-month, hands-on training in hemostatic techniques by using the compactEASIE model (in addition to clinical endoscopic training) vs. pure clinical training in endoscopic hemostatic methods. METHODS: Thirty-seven fellows in gastroenterology in New York City area training programs were enrolled. Baseline skills were assessed on the simulator for the following techniques: manual skills, injection and electrocoagulation, hemoclip application, and variceal ligation. Twenty-eight fellows were then randomized into two comparable groups. Those randomized to Group A received purely clinical training in endoscopic hemostatic techniques at their hospitals. Those in Group B, in addition, were trained by experienced tutors in 3 full-day hemostasis workshops over 7 months. Both groups underwent a final evaluation on the compactEASIE simulator conducted by their tutors and additional evaluators who were blinded to the method of training. Initial and final evaluation scores were compared for each group and between groups. Outcomes of actual clinical hemostatic procedures performed during the study period also were analyzed. RESULTS: Ten of 14 fellows randomized to Group A (standard training) and 13 of 14 in Group B (intensive training) returned for the final evaluation. For Group B, scores for all techniques were significantly improved. In Group A, a significant improvement was noted for variceal ligation alone. CONCLUSIONS: compactEASIE simulator training (3 sessions over 7 months), together with clinical endoscopic training resulted in objective improvement in the performance by fellows of all 4 endoscopic hemostatic techniques, whereas significant improvement was noted for variceal ligation alone for fellows who had standard clinical training. In clinical practice, fellows who had intensive simulator/clinical training had a significantly higher success rate and a nonsignificant reduction in the frequency of occurrence of complications.     

Efficacy and costs of a one-day hands-on EASIE endoscopy simulator train-the-trainer workshop

BACKGROUND: The efficacy of an intensive hands-on training in endoscopic hemostasis on the compactEASIE simulator has been previously demonstrated in a randomized prospective trial. In the current study, we evaluated how quickly and effectively new tutors, without simulator training experience, are able to acquire teaching skills in endoscopic hemostasis. METHODS: Five tutors with prior Erlangen Active Simulator for Interventional Endoscopy (EASIE) teaching experience instructed 7 endoscopists without prior EASIE experience on how to teach when using the model. These new tutors then independently conducted a workshop for 8 fellows in 4 hemostasis techniques. Results were compared with a historical control trained similarly by experienced tutors. Two one-day workshops in endoscopic hemostasis on the compactEASIE ex vivo endoscopy simulator were conducted in a category A hospital in New York City, New York. Skill scores at the end of training were compared with baseline skills assessments, and qualitative ratings of the new tutors were obtained from both the trainees and the experienced tutors. RESULTS: Significant improvement was achieved by the fellows in all 4 skills areas. Both the expert tutors and the trainees consistently rated the teaching skill of the new tutors highly. Fellows' skill acquisition using new tutors was of similar magnitude to that achieved in the prior EASIE trial using experienced trainers teaching the fellows. CONCLUSIONS: It is feasible to conduct an effective EASIE train-the-trainer course in one day. Tutors trained in this manner are able to provide a similar educational experience with objective improvement in trainee skill to experts who have conducted many hands-on workshops.     

The compactEASIE is a feasible training model for endoscopic novices: A prospective randomised trial

BACKGROUND: The objective benefit of a training using the compact Erlangen Active Simulator for Interventional Endoscopy-simulator was demonstrated in two prospective educational trials (New York, France). The present study analysed whether endoscopic novices are able to reach a comparable level of endoscopic skills as in the above-described projects. METHODS: Twenty-seven endoscopic novices (medical students, first year residents) were enrolled in this prospective, randomised trial. The compact Erlangen Active Simulator for Interventional Endoscopy-simulator with an upper GI-organ package and blood perfusion system was used as a training tool. Basic evaluation of endoscopic skills was performed after a practical and theoretical course in diagnostic upper GI endoscopy followed by a stratified randomisation according to the rating in endoscopic skills into intensive (n=14) and control group (n=13). The intensive group was trained 12 times every second week over 7 months in 4 endoscopic disciplines (manual skills, injection therapy, haemoclip, band ligation) by skilled endoscopist (three trainees/simulator). Assessment was performed (single steps/overall) using an analogue scale from 1 to 10 (1=worst, 10=optimal performance) by expert tutors. The control group was not trained. Blinded final evaluation of all participants was performed in January 2003. RESULTS: We observed in all techniques applied a significant improvement of endoscopic skills and of the performance time in the intensive group compared to the control group (p<0.001). The comparison with the previous projects showed that the intensively trained novices achieved comparable levels of performance to the GI fellows in the New York and France Project (at least 80% of the median score in three out of four techniques). CONCLUSION: Endoscopic novices acquired notable skills in interventional endoscopy in the simulator by an intensive, periodical training using the compactEASIE.     

Validation of computer simulation training for esophagogastroduodenoscopy: Pilot study

BACKGROUND: Little is known regarding the value of esophagogastroduodenoscopy (EGD) simulators in education. The purpose of the present paper was to validate the use of computer simulation in novice EGD training. METHODS: In phase 1, expert endoscopists evaluated various aspects of simulation fidelity as compared to live endoscopy. Additionally, computer-recorded performance metrics were assessed by comparing the recorded scores from users of three different experience levels. In phase 2, the transfer of simulation-acquired skills to the clinical setting was assessed in a two-group, randomized pilot study. The setting was a large gastroenterology (GI) Fellowship training program; in phase 1, 21 subjects (seven expert, intermediate and novice endoscopist), made up the three experience groups. In phase 2, eight novice GI fellows were involved in the two-group, randomized portion of the study examining the transfer of simulation skills to the clinical setting. During the initial validation phase, each of the 21 subjects completed two standardized EDG scenarios on a computer simulator and their performance scores were recorded for seven parameters. Following this, staff participants completed a questionnaire evaluating various aspects of the simulator's fidelity. Finally, four novice GI fellows were randomly assigned to receive 6 h of simulator-augmented training (SAT group) in EGD prior to beginning 1 month of patient-based EGD training. The remaining fellows experienced 1 month of patient-based training alone (PBT group). Results of the seven measured performance parameters were compared between three groups of varying experience using a Wilcoxon ranked sum test. The staffs' simulator fidelity survey used a 7-point Likert scale (1, very unrealistic; 4, neutral; 7, very realistic) for each of the parameters examined. During the second phase of this study, supervising staff rated both SAT and PBT fellows' patient-based performance daily. Scoring in each skill was completed using a 7-point Likert scale (1, strongly disagree; 4, neutral; 7, strongly agree). Median scores were compared between groups using the Wilcoxon ranked sum test. RESULTS: Staff evaluations of fidelity found that only two of the parameters examined (anatomy and scope maneuverability) had a significant degree of realism. The remaining areas were felt to be limited in their fidelity. Of the computer-recorded performance scores, only the novice group could be reliably identified from the other two experience groups. In the clinical application phase, the median Patient Discomfort ratings were superior in the PBT group (6; interquartile range [IQR], 5-6) as compared to the SAT group (5; IQR, 4-6; P = 0.015). PBT fellows' ratings were also superior in Sedation, Patient Discomfort, Independence and Competence during various phases of the evaluation. At no point were SAT fellows rated higher than the PBT group in any of the parameters examined. CONCLUSION: This EGD simulator has limitations to the degree of fidelity and can differentiate only novice endoscopists from other levels of experience. Finally, skills learned during EGD simulation training do not appear to translate well into patient-based endoscopy skills. These findings suggest against a key element of validity for the use of this computer simulator in novice EGD training.

Assessment of a bronchoscopy simulator.

The study objective was to validate a flexible bronchoscopy simulator by determining if it could differentiate between expert and novice bronchoscopists. A subsequent evaluation phase was then done to determine whether use of the simulator would improve the rate of bronchoscopy skill acquisition for new pulmonary fellows. A multicenter prospective cohort study was performed using a bronchoscopy simulator. Three cohorts were evaluated based on the number of bronchoscopies previously performed: "experts" (> 500, n = 9), "intermediates" (25 to 500, n = 8), and "novices" (none, n = 11). Each participant performed two simulated cases with performance measures being recorded by the simulator. Performance measures that distinguished between groups were then used to evaluate the learning curve for new fellows training on the simulator. A randomized-controlled trial was then conducted comparing the quality of bronchoscopy performance for new pulmonary fellows who were trained either with conventional methods or with the simulator. Expert bronchoscopists performed better on the simulator than intermediates who performed better than novices in terms of procedure time, percentage of segments visualized, time in red-out, and wall collisions. Training of new fellows demonstrated that after performing 20 bronchoscopic simulations, the skill level acquired with the simulator significantly improved in terms of speed, percentage of segments visualized, time in red-out, and collisions. Fellows trained on the simulator performed better than fellows trained using conventional methods during their first actual bronchoscopies as assessed by procedure time (815 versus 1,168 s, p = 0.001), a bronchoscopy nurse's subjective quality assessment score (7.7 +/- 0.3 versus 3.7 +/- 2.5, p = 0.05), and by a quantitative bronchoscopy quality score (percentage of segments correctly identified/procedure time, 0.119 +/- 0.015 versus 0.046 +/- 034, p = 0.03). In conclusion, the bronchoscopy simulator was able to accurately assess bronchoscopy experience level. Training new fellows on the bronchoscopy simulator leads to more rapid acquisition of bronchoscopy expertise compared with conventional training methods. This technology has the potential to facilitate bronchoscopy training and to improve objective evaluations of bronchoscopy skills.     

Assessment and learning curve evaluation of endobronchial ultrasound skills following simulation and clinical training

Background and objective: Endobronchial ultrasound is a revolutionary diagnostic pulmonary procedure. The use of a computer endobronchial ultrasound simulator could improve trainee procedural skills before attempting to perform procedures on patients. This study aims to compare endobronchial ultrasound performance following training with simulation versus conventional training using patients. Methods: A prospective study of pulmonary medicine and thoracic surgery trainees. Two cohorts of trainees were evaluated using simulated cases with performance metrics measured by the simulator. Group 1 received endobronchial ultrasound training by performing 15 cases on an endobronchial ultrasound simulator (n = 4). Group 2 received endobronchial ultrasound training by doing 15–25 cases on patients (n = 9). Results: Total procedure time was significantly shorter in group 1 than group 2 (15.15 (±1.34) vs 20.00 (±3.25) min, P < 0.05). The percentage of lymph nodes successfully identified was significantly better in group 1 than group 2 (89.8 (±5.4) vs 68.1 (±5.2), P < 0.05). There was no difference between group 1 and group 2 in the percentage of successful biopsies (100.0 (±0.0) vs 90.4 (±11.5), P = 0.13). The learning curves for simulation trained fellows did not show an obvious plateau after 19 simulated cases. Conclusions: Using an endobronchial ultrasound simulator leads to more rapid acquisition of skill in endobronchial ultrasound compared with conventional training methods, as assessed by an endobronchial ultrasound simulator. Endobronchial ultrasound simulators show promise for training with the advantage of minimizing the burden of procedural learning on patients.     

Multicenter, randomized, controlled trial of virtual-reality simulator training in acquisition of competency in colonoscopy

BACKGROUND: The GI Mentor is a virtual reality simulator that uses force feedback technology to create a realistic training experience. OBJECTIVE: To define the benefit of training on the GI Mentor on competency acquisition in colonoscopy. DESIGN: Randomized, controlled, blinded, multicenter trial. SETTING: Academic medical centers with accredited gastroenterology training programs. PATIENTS: First-year GI fellows. INTERVENTIONS: Subjects were randomized to receive 10 hours of unsupervised training on the GI Mentor or no simulator experience during the first 8 weeks of fellowship. After this period, both groups began performing real colonoscopies. The first 200 colonoscopies performed by each fellow were graded by proctors to measure technical and cognitive success, and patient comfort level during the procedure. MAIN OUTCOME MEASUREMENTS: A mixed-effects model comparison between the 2 groups of objective and subjective competency scores and patient discomfort in the performance of real colonoscopies over time. RESULTS: Forty-five fellows were randomized from 16 hospitals over 2 years. Fellows in the simulator group had significantly higher objective competency rates during the first 100 cases. A mixed-effects model demonstrated a higher objective competence overall in the simulator group (P < .0001), with the difference between groups being significantly greater during the first 80 cases performed. The median number of cases needed to reach 90% competency was 160 in both groups. The patient comfort level was similar. CONCLUSIONS: Fellows who underwent GI Mentor training performed significantly better during the early phase of real colonoscopy training.     

Prospective randomized study on the use of a computer-based endoscopic simulator for training in esophagogastroduodenoscopy

Background and Aim:  Computer-based endoscopic simulators have been developed in recent years, and their usefulness has been reported. However, there is no blinded prospective randomized controlled study on esophagogastroduodenoscopy (EGD) training using virtual reality simulators. The present study aimed to assess the effectiveness of a computer-based simulator for basic training in EGD.
Methods:  The GI-Mentor II simulator was used. The subjects were 20 hospital medical residents. After receiving an explanation regarding the fundamentals of endoscopy, 10 trainees were each randomized into a simulator group and a non-simulator group. The simulator group received 5 h of training with the GI-Mentor II plus bedside training, while the non-simulator group received bedside training. Subsequently, each subject performed endoscopy twice for assessment. Performance was evaluated according to a five-grade scale for a total of 11 items.
Results:  The score was significantly higher in the skills required for insertion into the esophagus, passing from the esophagogastric junction (EGJ) to the antrum, passing through the pylorus, and examination of the duodenal bulb and the fornix.
Conclusions:  The performance of endoscopy was improved by 5 h of simulator training. The simulator was more effective with regard to the items related to manipulation skills. Computer-based simulator training in EGD is useful for beginners.     

Efficacy of communication skills training for giving bad news and discussing transitions to palliative care

BACKGROUND: Few studies have assessed the efficacy of communication skills training for postgraduate physician trainees at the level of behaviors. We designed a residential communication skills workshop (Oncotalk) for medical oncology fellows. The intervention design built on existing successful models by teaching specific communication tasks linked to the patient's trajectory of illness. This study evaluated the efficacy of Oncotalk in changing observable communication behaviors. METHODS: Oncotalk was a 4-day residential workshop emphasizing skills practice in small groups. This preintervention and postintervention cohort study involved 115 medical oncology fellows from 62 different institutions during a 3-year study. The primary outcomes were observable participant communication skills measured during standardized patient encounters before and after the workshop in giving bad news and discussing transitions to palliative care. The standardized patient encounters were audiorecorded and assessed by blinded coders using a validated coding system. Before-after comparisons were made using each participant as his or her own control. RESULTS: Compared with preworkshop standardized patient encounters, postworkshop encounters showed that participants acquired a mean of 5.4 bad news skills (P<.001) and a mean of 4.4 transitions skills (P<.001). Most changes in individual skills were substantial; for example, in the bad news encounter, 16% of participants used the word "cancer" when giving bad news before the workshop, and 54% used it after the workshop (P<.001). Also in the bad news encounter, blinded coders were able to identify whether a standardized patient encounter occurred before or after the workshop in 91% of the audiorecordings. CONCLUSION: Oncotalk represents a successful teaching model for improving communication skills for postgraduate medical trainees.     

Geritalk: communication skills training for geriatric and palliative medicine fellows

Expert communication is essential to high‐quality care for older patients with serious illness. Although the importance of communication skills is widely recognized, formal curricula for teaching communication skills to geriatric and palliative medicine fellows is often inadequate or unavailable. The current study drew upon the educational principles and format of an evidence‐based, interactive teaching method to develop an intensive communication skills training course designed specifically to address the common communication challenges that geriatric and palliative medicine fellows face. The 2‐day retreat, held away from the hospital environment, included large‐group overview presentations, small‐group communication skills practice, and development of future skills practice commitment. Faculty received in‐depth training in small‐group facilitation techniques before the course. Geriatric and palliative medicine fellows were recruited to participate in the course and 100% (n = 18) enrolled. Overall satisfaction with the course was very high (mean 4.8 on a 5‐point scale). After the course, fellows reported an increase in self‐assessed preparedness for specific communication challenges (mean increase 1.4 on 5‐point scale, P < .001). Two months after the course, fellows reported a high level of sustained skills practice (mean 4.3 on 5‐point scale). In sum, the intensive communication skills program, customized for the specific needs of geriatric and palliative medicine fellows, improved fellows’ self‐assessed preparedness for challenging communication tasks and provided a model for ongoing deliberate practice of communication skills.     

Does Simulation‐Based Training Improve Procedural Skills of Beginners in Interventional Cardiology?—A Stratified Randomized Study

Objective

To assess whether mentored simulation‐based‐training can improve the procedural skills of beginners in coronary interventional procedures.

Background

Simulation based‐catheter training is a valuable tool to practice interventional procedures. Whether this type of training enhances the procedural skills of fellows learning percutaneous coronary interventions has never been studied.

Methods

Eighteen cardiology fellows were randomized either into the simulation‐based training (n = 9) or the control group (n = 9). The simulation group received 7.5 hours of virtual reality (VR) simulation training, whereas the control group attended 4.5 hours of lectures. Each participant had to perform a simple (pre‐evaluation) and a more complex (post‐evaluation) catheter intervention on a pulsatile coronary flow model in a catheterization laboratory. All procedures were videotaped, analyzed, and rated by 3 expert interventionalists, who were blinded to the randomization. To assess the individual performance level, a “skills score” was determined, comprising 14 performance characteristics (5‐level Likert scale, maximum score of 70 points).

Results

The “skills score” increased by 5.8 ± 6.1 points in the VR simulation group and decreased by 6.7 ± 8.4 in the control group (P = 0.003) from the simple stenosis at pre‐ to the more complex lesion at post‐evaluation demonstrating the effectiveness of simulation‐based training.

Conclusion

This pilot study suggests that curriculum‐based mentored VR simulation training improves the performance level of cardiology fellows in coronary interventions. Further investigation to evaluate the effect on clinical outcomes is warranted. (J Interven Cardiol 2016;29:75–82)

Performance of Temporary Hemodialysis Catheter Insertion by Nephrology Fellows and Attending Nephrologists

Background and objectives

Concerns have been raised about nephrology fellows’ skills in inserting temporary hemodialysis catheters. Less is known about temporary hemodialysis catheter insertion skills of attending nephrologists supervising these procedures. The aim of this study was to compare baseline temporary hemodialysis catheter insertion skills of attending nephrologists with the skills of nephrology fellows before and after a simulation-based mastery learning (SBML) intervention.

Design, setting, participants, & measurements

This pre- post-intervention study with a pretest-only comparison group was conducted at the University of Toronto in September of 2014. Participants were nephrology fellows and attending nephrologists from three university-affiliated academic hospitals who underwent baseline assessment of internal jugular temporary hemodialysis catheter insertion skills using a central venous catheter simulator. Fellows subsequently completed an SBML intervention, including deliberate practice with the central venous catheter simulator. Fellows were expected to meet or exceed a minimum passing score at post-test. Fellows who did not meet the minimum passing score completed additional deliberate practice. Attending nephrologist and fellow baseline performance on the temporary hemodialysis catheter skills assessment was compared. Fellows’ pre- and post-test temporary hemodialysis catheter insertion performance was compared to assess the effectiveness of SBML. The skills assessment was scored using a previously published 28-item checklist. The minimum passing score was set at 79% of checklist items correct.

Results

In total, 19 attending nephrologists and 20 nephrology fellows participated in the study. Mean attending nephrologist checklist scores (46.1%; SD=29.5%) were similar to baseline scores of fellows (41.1% items correct; SD=21.4%; P=0.55). Only two of 19 attending nephrologists (11%) met the minimum passing score at baseline. After SBML, fellows’ mean post-test score improved to 91.3% (SD=6.9%; P<0.001). Median time between pre- and post-test was 24 hours.

Conclusions

Attending nephrologists’ baseline temporary hemodialysis catheter insertion skills were highly variable and similar to nephrology fellows’ skills, with only a small minority able to competently insert a temporary hemodialysis catheter. SBML was extremely effective for training fellows and should be considered for attending nephrologists who supervise temporary hemodialysis catheter insertions.     

Combined simulation training: a new concept and workshop is useful for crisis management in gastrointestinal endoscopy

INTRODUCTION: Crisis management as well as realistic emergency situations can be trained in the new developed simulation workshop "Gastrointestinal Endoscopy and Crisis Resource Management" by combining a full-scale simulator and the Erlanger Endoscopy Trainer. The aim of the current study was to evaluate the efficiency of the newly developed simulation workshop. METHODS: Endoscopists with more than 12 months experience can train their endoscopic skills and crisis resource management with the help of different simulators. In addition, two different scenarios (GI bleeding with significant blood loss and sedation overdoses) embedded in a realistic surrounding (emergency room) have to be managed by the participants. Vital parameters, endoscopic skills, as well as personal interactions were recorded and graded. RESULTS: 100 participants took part in the newly developed workshop (between June and December 2003). The participants showed a significantly better endoscopic performance and a significantly better crisis management after the standardized training program. CONCLUSIONS: Simulation training plays an essential role in aviation and minimizes the risk for human errors. In the current study it is clearly shown that simulation training is also useful in gastrointestinal endoscopy. The newly developed workshop may thus be of crucial importance to improve personal crisis management. Simulation also leads to an improvement of endoscopic and emergency skills. Accordingly, simulation training should be recommended or offered as an education option in gastrointestinal endoscopy.     

Endoscopic training during fellowship: A nationwide French study: Impact of theoretical courses and simulation-based training during fellowship

BackgroundIn France, it is mandatory that gastroenterology fellows have mastered the basic level of endoscopy by the end of training. The aim of this study was to assess improvement in the quality of fellows’ endoscopy training in France during the last four years.MethodsAll fellows in France in training were eligible for participation. A 21-item questionnaire was sent out. The primary outcome was the completion by fourth year fellows of all the number of procedures recommended. Results were compared with those of a 2016 survey.ResultsTwo-hundred-and-sixty-five fellows responded to the survey. The participation rate was 47.0%. The mean age was 27.3 ± 1.0 years and 56.4% were female. Access to theoretical courses (63.7% vs. 30.6%, p < 0.001) and simulation-based training (virtual reality simulator: 58.4% vs. 28.2%, p < 0.001, animal models: 29.4% vs. 17.2%, p < 0.001) was significantly higher in 2020. Although the number of procedures did not increase, significantly higher perception of skill acquisition in colonoscopy as well as diminished pressure to advance procedures were noted.ConclusionAccess to theoretical courses and simulation-based training and perceived acquisition of numerous skills has gotten better. However, the quality of training in endoscopy still needs improvement.     

Use of a continuing medical education course to improve fellows' knowledge and skills in esophageal disorders

Advanced esophageal endoscopic procedures such as stricture dilation, hemostasis tools, and stent placement as well as high‐resolution manometry (HRM) interpretation are necessary skills for gastroenterology fellows to obtain during their training. Becoming proficient in these skills may be challenging in light of higher complication rates compared with diagnostic procedures and infrequent opportunities to practice these skills. Our aim was to determine if intensive training during a continuing medical education (CME) course boosts the knowledge and skills of gastroenterology fellows in esophageal diagnostic test interpretation and performance of therapeutic procedures. This was a pretest–posttest design without a control group of a simulation‐based, educational intervention in esophageal stricture balloon dilation and HRM interpretation. The participants were 24 gastroenterology fellows from 21 accredited US training programs. This was an intensive CME course held in Las Vegas, Nevada from August 7 to August 9, 2009. The research procedure had two phases. First, the subjects were measured at baseline (pretest) for their knowledge and procedural skill. Second, the fellows received 6 hours of education sessions featuring didactic content, instruction in HRM indications and interpretation, and deliberate practice using an esophageal stricture dilation model. After the intervention, all of the fellows were retested (posttest). A 17‐item checklist was developed for the esophageal balloon dilation procedure using relevant sources, expert opinion, and rigorous step‐by‐step procedures. Nineteen representative HRM swallow studies were obtained from Northwestern's motility lab and formed the pretest and posttest in HRM interpretation. Mean scores on the dilation checklist improved 81% from 39.4% (standard deviation [SD]= 33.4%) at pretest to 71.3% (SD = 29.5%) after simulation training (P < 0.001). HRM mean examination scores increased from 27.2% (SD = 16.4%) to 46.5% (SD = 15.8%), representing a 71% improvement (P < 0.001). Pearson's correlations indicated there was no correlation between pretest performance, medical knowledge measured by United States Medical Licensing Examination examinations, prior clinical experience, or procedural self‐confidence and posttest performance of esophageal dilation or HRM interpretation. The education program was rated highly. This study demonstrated that a CME course significantly enhanced the technical skills and knowledge of gastroenterology fellows in esophageal balloon dilation and HRM interpretation. CME courses such as this may be a valuable adjunct to standard fellowship training in gastroenterology.     

How many procedures are necessary to achieve competency in colonoscopy?

BACKGROUND: Competency for colonoscopy implies technical and cognitive skills. The American Society for Gastrointestinal Endoscopy has suggested 100 supervised procedures might be necessary. There are no specific recommendations in Brazil. AIM: To evaluate technical progress of trainees during a regular colonoscopy training program. MATERIALS AND METHOD: Two gastrointestinal fellows at Federal University of S?o Paulo, SP, Brazil, were prospectively evaluated during first year training. The frequency and time of reaching the cecum, total procedure duration, ability to identify lesions and patient discomfort were recorded. RESULTS: Two hundred and seventy one colonoscopies were preformed by both fellows (fellow A: 186 and B: 85). Twenty-seven cases were excluded of obstructive lesions or previous surgery, leading 171 and 72 exams, respectively. The mean success rate of reaching the cecum was 82.5% and 56.9%, respectively. For the first 72 exams it was 72.2% and 56.9%. Fellow A reached the cecum in 76% of first 100 colonoscopies, improving to 91.5% after the 101 st. Mean time for trainees to complete the procedure was 17.7 and 23.5 minutes to fellows A and B. Trainee A took 19.8 and 14.7 minutes before and after the 100th colonoscopy. DISCUSSION: Success rate and time taken to reach the cecum progressively improved over the number of procedures with statistical significance. However, because of individual differences, 100 colonoscopies may be insufficient to acquisition of technical skills. CONCLUSION: Although analyzing the learning curve of two fellows only, we could notice a statistically significant improve in reaching the cecum with experience over time. However, depending on individual skills more than 100 procedures may be necessary during training.     

The fellows stitch: large caliber venous hemostasis in pediatric practice

Objective : To analyze safety and efficiency of a subcutaneous figure of eight suture for hemostasis after large caliber venous sheath access in children. Background : Vascular complications remain a significant cause of morbidity after pediatric cardiac catheterization. In an attempt to reduce such complications and yet improve lab efficiency and decrease length of stay, various techniques have been applied to improve time to hemostasis. Methods : Prospectively recorded were vascular complications and hemostasis times in children where hemostasis was attempted using a figure of eight subcutaneous suture following large caliber venous cannulation. These were compared to a matched group achieving hemostasis using standard manual pressure techniques. Vascular ultrasound assessments were performed within 24 hr of hemostasis in both groups. Results : Thirty‐two subcutaneous sutures were placed in 26 children, mean weights 31.9 kg [median (range): 29.4 (8.4 to 96) kg], with a mean sheath French size of 9.2 [ 8 ; (6 to 22)], 11 >10 French, compared to 33 sheaths in 30 cases using manual compression, mean sheath French size 9.1 (9; (6 to 13), with 10 cases ≥10 French. The mean and median times to hemostasis were shorter in the suture group: 13.6 min (P < 0.05) and 10 min (P < 0.05), respectively. Vascular complication rate was also lower in the suture group (n = 0) compared with the control group (n = 2) but did not achieve statistical significance. Conclusions : A subcutaneous figure of eight suture hemostasis strategy can provide a safe and efficient method for large caliber venous hemostasis in a pediatric practice with improved hemostasis times and no additional morbidity. © 2011 Wiley Periodicals, Inc.
