Validation of an endoscopic part-task training box as a skill assessment tool

This study investigated whether the use of a simulator for endoscopic surgery training improves the performance of actual operations. For the study, 16 medical students were divided into three groups: a virtual reality (VR) simulator group (n = 6), a training box (TB) group (n = 6), and a control group (n = 4). The VR and TB groups received 2 h of training per day for 5 days, after which they were requested to perform intestinal dissection, to close a gastric perforation, and to perform cholecystectomy in pigs. Performance was assessed on the basis of the operating time and the error score. Although there were no differences between the three groups in terms of the total operating time or error score, the VR and TB groups required less time for closure of the gastric perforation than the control group. In addition, the operating time decreased as actual operating experience increased in the VR group. In the TB group, the time for closure of a gastric perforation was shorter when the supervisor had seen the operation before training. These findings demonstrated that a simulator is useful for acquiring psychomotor skills, but does not immediately enable clinical performance of an operation. More actual experience and good supervision are essential for increasing the effectiveness of training with the VR and TB simulators, respectively.

How To Maximize Trainee Education During the Coronavirus Disease-2019 Pandemic: Perspectives From Around the World

New advances in endoscopic surgery make it imperative that future gastrointestinal surgeons obtain adequate endoscopy skills. An evaluation of the 2001-02 general surgery residency endoscopy experience at the University of Missouri revealed that chief residents were graduating with an average of 43 endoscopic cases. This met American Board of Surgery (ABS) and Accreditation Council for Graduate Medical Education (ACGME) requirements but is inadequate preparation for carrying out advanced endoscopic surgery. Our aim was to determine if endoscopy volume could be improved by dedicating specific staff surgeon time to a gastrointestinal diagnostic center at an affiliated Veterans Administration Hospital. During the academic years 2002-05, two general surgeons who routinely perform endoscopy staffed the gastrointestinal endoscopy center at the Harry S. Truman Hospital two days per week. A minimum of one categorical surgical resident participated during these endoscopy training days while on the Veterans Hospital surgical service. A retrospective observational review of ACGME surgery resident case logs from 2001 to 2005 was conducted to document the changes in resident endoscopy experience. The cases were compiled by postgraduate year (PGY). Resident endoscopy case volume increased 850% from 2001 to 2005. Graduating residents completed an average of 161 endoscopies. Endoscopic experience was attained at all levels of training: 26, 21, 34, 23, and 26 mean endoscopies/year for PGY-1 to PGY-5, respectively. Having specific endoscopy training days at a VA Hospital under the guidance of a dedicated staff surgeon is a successful method to improve surgical resident endoscopy case volume. An integrated endoscopy training curriculum results in early skills acquisition, continued proficiency throughout residency, and is an efficient way to obtain endoscopic skills. In addition, the foundation of flexible endoscopic skill and experience has allowed early integration of surgery residents into research efforts in natural orifice transluminal endoscopic surgery.

Recently the Endoscopic Reference Score (EREFS) for endoscopic assessment of eosinophilic esophagitis was introduced, with good interobserver agreement for most signs. The EREFS has not yet been evaluated by other investigators and intraobserver agreement has not been assessed. The aim of this study was to further validate the EREFS by assessing interobserver and intraobserver agreement of endoscopic signs in patients with eosinophilic esophagitis. High-quality endoscopic images were made of the esophagus of 30 patients with eosinophilic esophagitis (age 36 years, range 23 - 46 years; 5 female), 6 of whom were in remission. At least three depersonalized images per patient were incorporated into a slideshow. Images were scored by four expert and four trainee endoscopists who were blinded to the patients' conditions. Interobserver agreement was assessed. After 4 weeks, the images were rescored in a different order to assess intraobserver agreement. Interobserver agreement was substantial for rings (κ 0.70), white exudates (κ 0.63), and crepe paper esophagus (κ 0.62), moderate for furrows (κ 0.49) and strictures (κ 0.54), and slight for edema (κ 0.12). Intraobserver agreement was substantial for rings (median κ 0.64, IQR 0.46 - 0.70), furrows (median κ 0.69, IQR 0.50 - 0.89), and crepe paper esophagus (median κ 0.69, IQR 0.62 - 0.83), moderate for white exudates (median κ 0.58, IQR 0.54 - 0.71) and strictures (median κ 0.54, IQR 0.33 - 0.70), and less than chance for edema (median κ 0.00, IQR 0.00 - 0.29). Inter- and intraobserver agreement was not substantially different between expert and trainee endoscopists. Using the EREFS, endoscopic signs of eosinophilic esophagitis were scored consistently by expert and trainee endoscopists.

ABSTRACTBackground and ObjectiveArtificial intelligence (AI) is reshaping gastrointestinal endoscopy, yet its role in training remains unexplored. This narrative review summarizes current evidence on AI‐assisted endoscopy training, addresses potential drawbacks, and envisions future directions.MethodsThis narrative review was performed via a systematic MEDLINE search (including articles from inception to January 2025), with search terms covering ‘AI’, ‘endoscopy,’ and ‘training.’ Studies were excluded if they were reviews, letters, editorials or comments; focused solely on model development; lacked a training component; or were limited to simple comparisons between the performance of endoscopists and AI systems. After screening 1443 records, 27 articles were included in this review.ResultsAI demonstrates potential in enhancing the training of various types of endoscopy (including luminal, hepatobiliary, capsule, and therapeutic endoscopy) by improving quality metrics, enhancing lesion detection, and guiding anatomical landmark recognition, yet the current applications are mainly task‐based. Future AI must evolve to provide comprehensive training and personalized performance tracking to endoscopists of different levels of experience. Further studies are needed to assess objective educational outcomes and cost‐effectiveness. Key concerns for AI adoption, including deskilling, over‐reliance, ethical considerations, and practicality, should be addressed through structured implementation, quality assurance, and regulatory framework.ConclusionIn conclusion, AI can augment endoscopy training by improving skill acquisition and procedural quality, yet significant gaps remain. More research is needed to support its widespread integration.

Su1091 State of Trainee Inflammatory Bowel Disease Education in the United States: A National Survey

BackgroundBox trainer systems have been developed that include advanced skills such as suturing. There is still a need for a portable, cheap training and testing system for basic laparoscopic techniques that can be used across different specialties before performing supervised surgery on patients. The aim of this study was to establish validity evidence for the Training and Assessment of Basic Laparoscopic Techniques (TABLT) test, a tablet‐based training system.MethodsLaparoscopic surgeons and trainees were recruited from departments of general surgery, gynaecology and urology. Participants included novice, intermediate and experienced surgeons. All participants performed the TABLT test. Performance scores were calculated based on time taken and errors made. Evidence of validity was explored using a contemporary framework of validity.ResultsSome 60 individuals participated. The TABLT was shown to be reliable, with an intraclass correlation coefficient of 0·99 (P < 0·001). ANOVA showed a difference between the groups with different level of experience (P < 0·001). The Bonferroni correction was used to confirm this finding. A Pearson's r value of 0·73 (P < 0·001) signified a good positive correlation between the level of laparoscopic experience and performance score. A reasonable pass–fail standard was established using contrasting groups methods.ConclusionTABLT can be used for the assessment of basic laparoscopic skills and can help novice surgical trainees in different specialties gain basic laparoscopic competencies.

The purpose of our study was to explore the effect of the physician's training level on the emergency management of common illnesses in the pediatric emergency department (ED). Our hypothesis was that physicians in training used more resources than attending physicians did in caring for pediatric patients in the ED. We retrospectively reviewed all records of patients younger than 18 years who presented to the pediatric section in ED of Taipei Veterans General Hospital between January 1, 2004, and December 31, 2005. The cohort study was composed of patients treated by a pediatric attending physician (group 1) or treated by a resident (group 2). We collected their demographic data, diagnoses, admission and revisiting rates, direct costs (including radiographic, laboratory, and medication costs per visit), and utilization data. Admission and 72-hour revisiting rates did not differ between groups. Lengths of ED stay and total, radiographic, and medication costs significantly increased with the residents (all P < 0.001). Residents ordered more radiographic (30.7% vs 23.8%, P < 0.001) and laboratory (37.2% vs 34.6%, P = 0.13) studies than attending physicians did, notably when patients had acute bronchitis and bronchiolitis or noninfectious gastroenteritis and colitis. Residents also ordered more laboratory studies in cases of pneumonia. Residents treating pediatric patients in the ED spent more time and used more medical resources than attending physicians did. An important educational objective is to improve physicians' diagnostic skills to reduce resource utilization and to improve outcomes.

Both the amount of information available to judges and their level of professional training have been identified as variables relevant to accurate personality predictions. This study represented an attempt to determine the optimal amount of Rorschach protocol information essential to accurate personality descriptions for judges at various levels of professional experience. Four groups of 25 judges (Fellows in the Society for Projective Techniques, recently graduated Ph.D.'s, Graduate and Undergraduate students) responded to sets of true-false personality statements which referred to a patient whose Rorschach protocol had been supplied to them. The results indicated that aside from occasional exceptions: 1. No significant improvement in predictive accuracy occurred as the level of training and/or experience increased. 2. Increases in the amount of protocol information did not significantly improve the judges' understanding of the patient, as measured by the criterion. 3. The Rorschach appears best...

Interobserver Analysis of Standard Foot and Ankle Radiographic Angles

Competency in endoscopy has traditionally been based on number of procedures performed. With movement towards milestone-based accreditation, new standards of establishing competency are required. The Thompson Endoscopic Skills Trainer (TEST) is a training device previously shown to differentiate between novice and expert endoscopists. This study aims to correlate TEST scores to other markers of performance in endoscopy. Trainees of a gastroenterology fellowship program were guided through the TEST. Their scores and sub-scores were correlated to their endoscopic metrics of performance, including adenoma detection rate, cecal intubation rate, cecal intubation time, withdrawal time, fentanyl usage, midazolam usage, pain score, overall procedure time, and performance on the ASGE Assessment of Competency in Endoscopy Tool (ACE Tool). The Overall Score positively correlated with the ACE Tool Total Score (r = 0.707, p = 0.010) and sub-scores (Cognitive Skills Score: r = 0.624, p = 0.030; Motor Skills Score: r = 0.756, p = 0.004), and negatively correlated with cecal intubation time (r = -0.591, p = 0.043). The Gross Motor Score positively correlated with cecal intubation rate (r = 0.593, p = 0.042), ACE Tool Total Score (r = 0.594, p = 0.042) and Motor Skills Score (r = 0.623, p = 0.031), and negatively correlated with cecal intubation time (r = -0.695, p = 0.012). The Fine Motor Score positively correlated with the ACE Tool Polypectomy Score (r = 0.601, p = 0.039), and negatively correlated with procedure time (r = -0.640, p = 0.025), cecal intubation time (r = -0.645, p = 0.024), and withdrawal time (r = -0.629, p = 0.028). This study demonstrates that performance on the TEST correlate to endoscopic measures. Given these results, the TEST may be used in conjunction with existing assessment tools for demonstrating competency in endoscopy.

Single Center Neurosurgical Outcomes and Trends in Endoscopic Endonasal Resection of 297 Sellar/Suprasellar Tumors Stratified by Duration of Neurosurgical Career

When comparing a single-stroke dissection maneuver among surgeons with differing experience levels, there are major differences in the force applied to the instrument tip. It is difficult to explain to surgeons in training the appropriate force and for the surgeons to ascertain the force intuitively. We quantified the force pattern during single-stroke laparoscopic dissection maneuvers to reveal the factors related to expertise. We recorded the force pattern of a single maneuver and measured the magnitude of vertical (VF) and horizontal forces (HF) on the instrument tip using a box trainer (ex vivo). We compared VF and HF among surgeons: experts (n = 10), intermediates (n = 10), and novices (n = 10). The dissection time of a single stroke (T), magnitude of the VF and HF, and the timing of the peak vertical force (TPV) and horizontal force (TPH) were evaluated as performance parameters. The dissection time of a single stroke (T) was shortest in the expert group (p < 0.05). The average maximum magnitude of VF and HF was smallest in the expert group. TPV occurred significantly earlier than TPH in all three groups (p < 0.05). TPV in the expert group occurred earlier than in the intermediate and novice groups (p < 0.05). With increasing experience, TPV occurred earlier. Expert surgeons apply the most efficient vertical forces to make an initial dissection point and then change to the horizontal direction to separate surrounding tissues from the target organ. Measuring instrument tip force could help in understanding and improving the safety margin in laparoscopic surgical dissection.
