A multi-modal training environment for colonoscopy with pressure feedback.
Article in Surgical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundColonoscopy is a complex procedure with a 3-5% failure rate even for experts. Mastering endoscopy skills and reducing complication rates extend well beyond the initial training phase for most endoscopists, and continues into their clinical experience. Thus, continuing efforts should focus on optimizing training methods to make them individualized with clear objective learning goals for trainees.
methodsA hybrid (physical and computer) colonoscopy training simulator was developed using a novel pressure-sensing sleeve covering the full length of a colonoscope, and a physical colon simulator (Kyoto Kagaku) along with custom-designed training software to visualize the color-mapped 3D pressure profile of the colonoscope during the simulated procedure and provide a visual and quantitative evaluation of the endoscopist's skills post-procedure. A system usability questionnaire and objective evaluation metrics were used to determine the model's effectiveness as a training tool.
resultsThirty-three participants were enrolled in the study, among which 8 were experts and 25 trainees. The interactive maximum and average pressures applied by the trainees were generally higher than those applied by experts, however, this difference was only statistically significant in the recto-sigmoid region. The mean average pressure applied in the rectum and the rectosigmoid region was 6.5 kPa for the experts compared to 13.7 kPa for the trainees, with a p-value of 0.011. Both groups agreed that the system is easy to understand and use, and would be helpful as a learning aid in training programs for colonoscopy skills.
conclusionsThe proposed system is expected to enhance the quality of colonoscopy procedures by enabling endoscopists to adopt safer and more efficient navigational skills. The evaluation metrics discussed in this research offer useful insights into the performance of endoscopists, and the ability of trainees to compare their performance against expert benchmarks will enable them to establish personalized objective training goals.
