Semantic segmentation deep learning model boosts surgeons' organ recognition in minimally invasive hysterectomy - a prospective multi-center reader performance study using pre-selected video clips.

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
backgroundInjury to the ureter and bladder during minimally invasive hysterectomy remains a serious complication, often resulting from insufficient intraoperative organ recognition. Artificial intelligence (AI)-based support systems may improve anatomical recognition and reduce such risks. We aimed to evaluate whether an AI-based anatomical recognition system for the ureter and bladder improves surgeons' organ recognition abilities across different experience levels without compromising specificity. MATERIALS AND
methodsA deep learning model was trained on 13 934 ureter and 4940 bladder images sourced from 41 institutions. Model performance was evaluated using the Dice coefficient. The performance of 16 surgeons from eight facilities was evaluated for identifying the ureter and bladder in pre-recorded surgical videos with and without AI support. Sensitivity and specificity were compared between AI-assisted and non-assisted conditions, stratified by surgeon experience.
resultsThe AI model achieved a Dice coefficient of 0.66 for ureter segmentation and 0.62 for bladder segmentation. AI assistance significantly improved sensitivity for ureter detection (43.5-58.1%, P < 0.001) and bladder detection (54.2-70.0%, P < 0.001) without reducing specificity. The additive effect of AI was greater in less experienced surgeons, with sensitivity improvements of 27.3% for ureter and 26.8% for bladder recognition. Ureter recognition was stable across surgical phases, while bladder recognition demonstrated moderate variability.
conclusionsThe AI-based system enhanced surgeons' ability to recognize the ureter and bladder on surgical video, particularly among less experienced surgeons, without increasing the risk of misidentification. AI may help improve intraoperative anatomical identification and potentially contribute to safer, more standardized surgical performance.
