Clinical significance of hiatus hernia on Barrett's oesophagus: a scoping review.
Article in Langenbeck's archives of surgery, 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
backgroundHiatal hernia (HH) is commonly observed in patients with Barrett’s oesophagus (BO), a premalignant condition that may progress to oesophageal adenocarcinoma (OAC). While HH has been implicated in BO pathogenesis, it is not formally recognised as a major risk factor in leading international clinical guidelines. This systematic scoping review aimed to evaluate the role of HH in the development, progression, and treatment outcomes of BO.
methodsA systematic scoping review was conducted, searching through databases (PubMed, Medline, Embase, Scopus).
resultsA total of sixty-six articles were included with majority comprised of observational studies. HH was strongly associated with BO development, particularly in cases with larger hernia size (> 2–4 cm) and long-segment BO. While inconsistent, there could BO a trend towards dysplastic and malignant progression of BO in HH. HH may impair the efficacy of radiofrequency ablation, with larger hernias requiring more treatment sessions.
conclusionCurrent evidence supports HH as a significant risk factor for BO onset. Its role in progression and management warrants further investigation. Surgical repair may be beneficial in selected asymptomatic patients, especially those with hernias ≥ 4 cm and established BO, to restore the gastro-oesophageal anatomy and eliminate reflux-prone micro-environment.
