Roux-en-Y Gastric Bypass and Sleeve Gastrectomy Risk-Adjusted Safety Profiles after Previous Fundoplication: A 499-Patient MBSAQIP Analysis.
Article in Obesity 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
backgroundObesity and gastroesophageal reflux disease (GERD) frequently coexist and may necessitate surgical intervention when conservative management fails. While fundoplication is effective for GERD, many patients ultimately require metabolic and bariatric surgery (MBS) for obesity. The safety and prevalence of sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) after prior fundoplication remains poorly characterized.
objectivesTo assess the prevalence and 30-day serious complication rates of SG and RYGB following fundoplication, and to identify independent predictors of adverse outcomes.
methodsA retrospective analysis of the 2022–2023 MBSAQIP database identified 499 patients undergoing primary SG or RYGB after fundoplication. Outcomes assessed included leak, bleeding, reoperation, reintervention, cardiac events, pneumonia, kidney injury, thromboembolism, infection, or sepsis. Multivariable logistic regression was used to adjust for baseline differences.
resultsOf 499 patients, 126 (25.3%) underwent SG (F-SG) and 373 (74.7%) underwent RYGB (F-RYGB). Concomitant paraesophageal hernia repair was more common in the F-RYGB group (54.2% vs. 26.2%, p < 0.001). Mean BMI was higher in F-SG (42.4 vs. 40.1 kg/m², p < 0.001). Weight gain and GERD were the leading indications for revisional bariatric surgery. F-RYGB was associated with longer operative times, hospital stay, and higher rates of reoperation, readmission, bowel obstruction, and serious complications (9.6% vs. 4.0%, p = 0.045). Rates of anastomotic leak, postoperative bleeding, and composite wound complications were low but numerically higher in F-RYGB, without statistical significance. In multivariate analysis, procedure type was not significantly associated with serious complications (OR 2.03, 95% CI 0.68–6.09, p = 0.207).
conclusionsBoth SG and RYGB appear to be safe and effective revisional options, and a history of fundoplication should not be considered a contraindication. Although RYGB was associated with longer operative times and higher early complication rates, multivariable analysis showed no significant difference in serious complications between the two procedures.
