Diagnostic performance of ultrasound for gastric volvulus in pediatric patients.
Article in Journal of ultrasound, 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
purposeIn this study, we aimed to evaluate the diagnostic performance of ultrasound for gastric volvulus. The characteristics of patients with gastric volvulus were also evaluated.
methodsThirty-seven pediatric patients with gastric volvulus, diagnosed based on an upper gastrointestinal series, were classified into two groups: organoaxial and mesenteroaxial. The diagnostic performance of ultrasound for gastric volvulus and its usefulness in the management of these patients were also examined. Age, symptom onset, and presence/absence of diaphragmatic elevation/hernia, scoliosis, and wandering spleen of the two groups were compared using Fisher's exact and the Mann-Whitney U test.
resultsAmong the 37 eligible patients, 28/9 had organoaxial/ mesenteroaxial gastric volvulus, respectively. Seven of these patients (18.9%) were correctly diagnosed using ultrasound. In 31/37 patients, ultrasound ruled out other disease-related symptoms indicative of gastric volvulus. Significant inter-group differences were observed for age (age (years) with organoaxial vs. mesenteroaxial gastric volvlulus = 2.24 ± 4.22 [0.01-14.98] vs.5.77 ± 4.45 [0.23-15.87], P = 0.010), acute/chronic onset of symptom (acute/chronic onset of symptom with organoaxial vs. mesentaroaxial gastric volvlulus = 5/23 vs. 5/4, P = 0.041), wandering spleen (present/absent of those with organoaxial vs. mesenteroaxial gastric volvulus = 0/28 vs. 6/3, P = 0.001), and scoliosis (present/absent of those with organoaxial vs, mesenteroaxial gastric volvulus = 1/27 vs. 3/6, P = 0.038).
conclusionTo our knowledge, this study is the first to demonstrate the diagnostic performance of ultrasound for gastric volvulus. Although small number of cases of gastric volvulus were diagnosed using ultrasound, its diagnostic performance was unreliable. However, ultrasound was useful in differentiating gastric volvulus from other diseases with similar symptoms.
