Roux-en-Y gastric bypass: impact of surgical approach on short-term postoperative complications.
Article in Journal of robotic 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
objectiveTo compare 30-day postoperative complications after Roux-en-Y gastric bypass performed using a robot-assisted approach (RRYGB) versus a laparoscopic approach (LRYGB).
methodsWe conducted a retrospective single-center study including adult patients undergoing primary RYGB between February 2021 and November 2024. Early postoperative complications (≤ 30 days) were analyzed in the entire cohort and compared between surgical approaches, with propensity-score matching performed to reduce confounding. Complications occurring beyond 30 days were analyzed descriptively up to 1 year postoperatively, without matching, due to heterogeneous follow-up.
resultsAmong the 406 patients included (27.1% LRYGB, 72.9% RRYGB), 15.3% experienced at least one 30-day postoperative complication, with no significant difference between groups (LRYGB: 20.1% vs. RRYGB: 13.2%, p = 0.09). After matching, this difference remained non-significant (20.2% vs. 13.8%, p = 0.279). The severity of complications according to the Clavien-Dindo classification was comparable between groups. However, the reoperation rate was significantly higher in the LRYGB group (8.2% vs. 1.7%, p = 0.004). Operative time was shorter for laparoscopy (74.2 min vs. 83.5 min, p < 0.001). No significant difference was observed regarding complications beyond 30 days.
conclusionIn this high-volume bariatric center, robotic and laparoscopic RYGB demonstrated comparable short- and mid-term safety profiles. The robotic approach was not associated with increased early or late morbidity and was associated with a lower rate of early surgical reinterventions. These findings support robotic RYGB as a safe and reliable alternative to laparoscopy in experienced centers. Further studies with standardized long-term follow-up are needed to better define potential long-term benefits of robotic assistance.
