The short-term effect of laparoscopic sleeve gastrectomy with his angle reconstruction (LSG-His) on gastroesophageal reflux disease.
Observational study in BMC gastroenterology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveWhile laparoscopic sleeve gastrectomy (LSG) is an established bariatric procedure for obesity, postoperative gastroesophageal reflux disease (GERD) remains a significant complication. This study evaluates the short-term efficacy of a novel technique combining LSG with acute angle of His reconstruction (LSG-His) versus conventional LSG.
methodsThis is a single center retrospective observation cohort study. Among 83 patients undergoing bariatric surgery, 39 receiving conventional LSG and 44 undergoing LSG-His (with diaphragmatic fundopexy using 2-0 Prolene sutures) were analyzed. GERD symptoms were assessed using the Reflux Diagnostic Questionnaire (RD-Q) and GERD Questionnaire (GERD-Q) at baseline and at 3-, 6-, 12-, 24-month postoperatively. Weight loss outcomes included percentage of excess weight loss (%EWL) and total weight loss.
resultsPostoperative follow-up showed a sustained reduction in GERD symptoms for the LSG-His group across all time points using both scoring systems (all p<0.001 vs LSG). The results demonstrated that, when assessed using the GERD-Q at the 24-month follow-up, the prevalence of GERD symptoms was 14% (95% CI: 6.3% - 25.7%) among LSG-His patients versus 46% (95% CI: 32.1% - 60.7%) among LSG patients (p<0.001). As evaluated via the RD-Q at the same 24-month follow-up, GERD symptom prevalence was 7% (95% CI: 2.3%- 17.9%) in the LSG-His group compared with 41% (95% CI: 27.3% - 56.3%) in the LSG group (p<0.001).%EWL was higher in the LSG-His group at 3 months (54.7% vs 46.5%, p=0.033), 6 months (73.8% vs 64%, p=0.047), 12 months (82.9% vs 72.2%, p=0.042) and 24 months (84.1% vs 75.4%, p=0.038) follow-up compared to LSG group.
conclusionIn this retrospective observational study, LSG-His was associated with lower rates of GERD symptoms and higher %EWL compared to standard LSG, but with comparable %TWL in 24 month outcomes. However, these preliminary results are limited to short-term follow-up, and long-term prospective studies with objective reflux assessment are warranted.
