Real-time AI assistance improves adherence to standardized biliopancreatic EUS examination: a real-world comparative study.
Article in Gastroenterology report, 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
Background: Biliopancreatic endoscopic ultrasound (EUS) is highly operator-dependent, and adherence to standardized examination pathways may vary in routine practice. Evidence on whether real-time artificial intelligence (AI) assistance improves adherence to standardized biliopancreatic EUS examination in real-world settings remains limited. Methods: We conducted a retrospective comparative cohort study at a tertiary referral center to evaluate the real-world implementation of a real-time AI assistance system during biliopancreatic EUS. Examinations from the pre-AI period were compared with those from the post-AI period after a washout interval. Propensity score matching and interrupted time-series analysis were used to reduce baseline imbalance and assess temporal changes. The primary outcome was adherence to the standardized examination protocol, operationalized as total documentation completeness across eight predefined anatomical stations. Secondary outcomes included station-level adherence and lesion detection, with prespecified evaluation of pancreatic masses smaller than 2 cm. Results: Among 1,465 eligible examinations, 854 matched examinations (427 per group) were analyzed. Adherence to the standardized eight-station examination was higher in the post-AI group, reflected by greater total documentation completeness (89.93% vs 81.29%, adjusted absolute difference 8.65%, 95% confidence interval [CI] 6.58-10.71, Conclusions: In this real-world comparative study, real-time AI assistance was associated with greater adherence to a standardized biliopancreatic EUS examination protocol and a higher observed detection rate of pancreatic masses smaller than 2 cm. These findings suggest that real-time AI assistance may facilitate more standardized biliopancreatic EUS examination in routine practice.
