Concomitant hiatal hernia repair during laparoscopic sleeve gastrectomy and 5-year endoscopic esophagitis: a retrospective cohort study of 400 patients.
Article in Surgical endoscopy, 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
backgroundReflux-related mucosal injury remains an important long-term concern after laparoscopic sleeve gastrectomy (LSG). Hiatal hernia (HH) is a potentially modifiable anatomical factor, but long-term endoscopic evidence on the effect of concomitant hiatal hernia repair (HHR) during LSG remains limited.
methodsThis single-center retrospective cohort study, reported in accordance with STROBE, included 400 consecutive patients who underwent primary LSG in 2019. Preoperative upper endoscopy was performed in all patients. HH was defined intraoperatively and selectively repaired by concomitant posterior cruroplasty. Five-year endoscopy was available in 356 patients (89.0%). The primary outcome was endoscopic esophagitis according to intraoperative HH status and concomitant HHR.
resultsHH was identified in 115/400 patients (28.8%) and repaired in 75 (65.2%). At 5 years, esophagitis was present in 36/356 patients (10.1%): 27 had LA-A and 9 LA-B esophagitis, with no LA-C or LA-D cases. Barrett's esophagus was identified in 4/356 patients (1.1%), and 88/356 (24.7%) were receiving proton-pump inhibitor therapy. Esophagitis occurred in 4/75 patients with repaired HH (5.3%), 9/40 with unrepaired HH (22.5%), and 23/241 without HH (9.5%) (overall p=0.013). Compared with unrepaired HH, concomitant HHR was associated with lower odds of esophagitis (OR 0.19, 95% CI 0.06-0.68; p=0.011), an association that persisted after stratification for baseline clinical-endoscopic status (Mantel-Haenszel common OR 0.14, 95% CI 0.04-0.57; p=0.003). No Barrett's esophagus was observed among patients undergoing HHR.
conclusionsEsophagitis was significantly less frequent after concomitant HHR during LSG than when an intraoperatively identified HH was left unrepaired. Although the observational design precludes causal inference, these findings provide long-term endoscopic evidence supporting concomitant HHR when technically feasible.
