Post Roux-en-Y Gastric Bypass Challenges: Gastrogastric Fistula After Marginal Ulcer Development.
Article in Obesity surgery, 2025. 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
backgroundGastrogastric fistula (GGF) is a rare complication following Roux-en-Y gastric bypass (RYGB). Various causative factors, including marginal ulcer (MU), can predispose to GGF development. Currently, no studies address surgical management of GGF after MU diagnosis. This study aims to report our experience in such cases.
methodsA retrospective analysis of patients who underwent revisional surgery for GGF after MU diagnosis from 2016 and 2024. Patient demographics were collected, and peri- and postoperative outcomes were evaluated, including weight loss, complications, reinterventions, and MU recurrence.
resultsA total of 20 patients underwent revisional bariatric surgery (RBS) for resolution of GGF, with 13 (65%) treated under a robotic-assisted approach. The mean body mass index (BMI) at revision was 32.9 kg/m
conclusionsGGF is a rare complication following RYGB and MU development. Given the high recurrence rate associated with medical and endoscopic treatments, surgical resolution is a feasible option to effectively address this complication. However, MU recurrence can still occur in approximately 25% of cases.
