Clinical presentation and outcomes of revisional Roux-en-Y gastric bypass after failed gastric banding: direct versus sleeve-assisted approach.
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
backgroundFollowing failed adjustable gastric banding (AGB), patients may undergo direct conversion to Roux-en-Y gastric bypass (RYGB) or progress through an intermediate sleeve gastrectomy (SG) prior to revisional bypass. The impact of these differing revisional pathways on clinical presentation and postoperative outcomes remains unclear.
methodsA retrospective cohort study was performed of adult patients undergoing revisional RYGB after prior AGB between 2013 and 2025 at a single academic center. Patients were categorized into direct AGB-RYGB and two-step AGB-SG-RYGB conversion groups. Clinical presentation, perioperative outcomes, postoperative complications, weight loss trajectories, and comorbidity resolution were compared.
resultsSeventy-eight patients underwent revisional RYGB after prior AGB, including 53 direct AGB-RYGB conversions and 25 AGB-SG-RYGB conversions. Patients undergoing direct conversion more commonly presented with weight regain symptoms (81.1 vs 16.0%, p < 0.01) and had higher preoperative BMI (43.1 ± 7.4 vs 36.1 ± 7.2 kg/m
conclusionsPatients undergoing revisional RYGB after failed AGB represent distinct clinical populations depending on revisional pathway. Despite differing symptom profiles and operative histories, perioperative outcomes were comparable. Greater early and intermediate weight loss was observed in the direct AGB-RYGB group, whereas the AGB-SG-RYGB pathway demonstrated greater GERD symptom resolution. These findings should be interpreted in the context of differences in baseline BMI and indications for revision between groups.
