Automated overview of complete endoscopies with unsupervised learned descriptors.
Article in International journal of computer assisted radiology and surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeWe aim to automate the initial analysis of complete endoscopy videos, identifying the sparse relevant content. This facilitates long procedure recording understanding, reduces the clinicians' review time, and facilitates downstream tasks such as video summarization, event detection, and 3D reconstruction.
methodsOur approach extracts endoscopic video frame representations with a learned embedding model. These descriptors are clustered to find visual patterns in the procedure, identifying key scene types (surgery, clear visibility frames, etc.) and enabling segmentation into informative and non-informative video parts.
resultsEvaluation on complete colonoscopy videos presents good performance identifying surgery segments and different visibility conditions. The method produces structured overviews that separate useful segments from irrelevant ones. We illustrate its suitability and benefits as preprocessing for other downstream tasks, such as 3D reconstruction or video summarization.
conclusionOur approach enables automated endoscopy overview generation, helping the clinicians focus on the relevant video content such as good visibility sections and surgery actions. The presented work facilitates faster recording reviewing for clinicians and effective video preprocessing for downstream tasks.
