Fizz-computed tomography as a novel modality of objective esophageal hiatal assessment.
Article in Langenbeck's archives of surgery, 2025. 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
backgroundTraditional investigations of esophageal hiatal assessment for reflux disease and hiatal hernia (HH), such as endoscopy and barium swallow are subjective. High resolution manometry (HRM) limits hiatal hernia assessment to vertical length. We report a novel use of 3D volumetric Computed Tomography with effervescent oral contrast (Fizz-CT) as a means of preoperative HH diagnosis.
methodsA pilot series of 12 consecutive patients who underwent preoperative Fizz-CT assessment, as well as a combination of traditional investigations for HH (five primary, seven revisional HH).
resultsThe median age was 70years (IQR 57.5-76.8years) and median BMI 28.62 kg/m
conclusionFizz-CT imaging is a novel and accurate means of objective esophageal hiatal assessment in both primary and revisional HH patients. Vertical and radial measures of hiatal defects as well as hernia volumetry can be obtained. In post-surgical patients the relationship between the esophago-gastric junction and an infra- or supra-diaphragmatic fundoplication can also be assessed.
