Robotic hand-sewn vs. laparoscopic linear-stapled Roux-en-Y gastric bypass: a propensity score-matched analysis of primary and conversion cases.

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
Background: Roux-en-Y gastric bypass (RYGB) is performed as a primary procedure or as a conversion from sleeve gastrectomy for complications such as gastroesophageal reflux disease (GERD) or weight regain. Robotic hand-sewn gastrojejunostomy may improve precision compared with laparoscopic linear stapling, but comparative evidence remains limited. This study compared robotic hand-sewn and laparoscopic linear-stapled RYGB using propensity score matching (PSM). Methods: This retrospective cohort study included 67 patients undergoing primary or conversion RYGB at a Saudi tertiary center (2016-2024). After PSM, 26 robotic cases (11 primary, 15 conversion) were matched with 26 laparoscopic cases based on demographic and clinical variables. Outcomes included operative time, length of stay (LOS), postoperative pain, narcotic use, complications, costs, body mass index (BMI) reduction, and comorbidity improvement. Statistical significance was set at Results: Matched groups were comparable (mean age 46 ± 8 years; BMI 41 ± 6 kg/m²). Robotic procedures had longer operative times (178 ± 25 vs. 158 ± 22 min, Conclusion: Robotic and laparoscopic RYGB show comparable efficacy and safety. The robotic approach reduces pain and narcotic use, with a trend toward shorter hospital stay, but increases operative time and costs, supporting selective use in complex cases.
