Robotic Assistance and Early Small Bowel Obstruction after Roux-en-Y Gastric Bypass: a Rare Event 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
backgroundRobotics has gained increasing adoption for roux-en-y gastric bypass, offering improved visualization and precision. However, unique anatomic configurations, such as the "Brazilian technique," may predispose to early small bowel obstruction (eSBO).
methodsWe performed a retrospective cohort study using the 2023 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database to evaluate adults undergoing gastric bypass. The primary exposure was robotic assistance. eSBO within 30 days was identified from main and ancillary files. Associations were analyzed using rare-event logistic regression, adjusting for demographic, comorbid, and procedural covariates.
resultsAmong 20,162 roux-en-y gastric bypasses (38.4% robotic), eSBO occurred in 1.74% overall, with higher incidence after robotic versus laparoscopic procedures (2.11% vs. 1.50%, p < 0.01). Robotic assistance independently predicted eSBO (OR 1.24, 95% CI 1.00-1.55, p = 0.04). The association remained consistent in patients with and without prior foregut surgery, primary, revision and conversion procedures. Overall, gastric bypass patients with eSBO experienced a readmission rate of 74.57%, reoperation rate of 36.29%, and needing other interventions in 22.86%.
conclusionsRobotic assistance independently increases the risk of eSBO following roux-en-y gastric bypass. Technical differences inherent to the robotic approach may contribute and warrant further investigation.
