Efficacy of Gel Immersion Tumor Characterization for Colorectal Lesions: A Pilot Study.
Article in Digestive diseases and sciences, 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
backgroundGel immersion endoscopy is a novel method that uses gel to enhance the visual field. This study aimed to analyze the efficacy of magnified endoscopy under gel immersion for optimal visualization and characterization of colorectal tumors.
methodsWe retrospectively examined 107 lesions observed with blue-laser/light imaging (BLI) or narrow-band imaging (NBI) between June 2022 and July 2023 using the Japan NBI Expert Team classification. The lesions underwent magnified endoscopy first with CO
resultsAmong the 107 lesions, the mean tumor size was 22.7 ± 11.8 mm and 58 lesions were non-polypoid. Histopathology revealed 15 sessile serrated lesions, one sessile serrated lesion with dysplasia, 36 low-grade dysplasias, 37 high-grade dysplasias, 14 adenocarcinoma (≥ T1) cancers, and four others. Gel immersion resulted in significantly less halation compared to CO
conclusionsThe reduced halation, bubbles, and internal fluid with gel immersion provided excellent visualization. The diagnostic accuracy for colorectal lesions using the gel immersion method was comparable to that of CO₂ insufflation and underwater methods.
