Laparoscopic Reversal of Gastric Bypass: A Retrospective Review.
Article in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundGastric bypass can result in serious complications such as dumping syndrome, Malnutrition, and chronic abdominal pain refractory to symptomatic treatment and necessitate surgical intervention in the form of reversal to normal anatomy. Our study draws on a 5-year experience in the reversal of gastric bypass, addressing indications, operative techniques, and complications associated with this procedure.
methodsThis retrospective analysis pilot study included ten patients who underwent reversal of either Roux-en-Y gastric bypass (RYGB) or one-anastomosis gastric bypass (OAGB) and investigated their indications, complications, and outcomes.
resultsTen patients underwent gastric bypass reversal; 60% of them had a reversal of OAGB, while 40% had a reversal of RYGB. The main indications for bypass reversal were malnutrition (hypoalbuminemia) (33%), excessive loss of weight (29%), followed by chronic abdominal pain, chronic anemia, diarrhea, non-healing Marginal ulcer, and persistent reflux, representing 10% each. Follow-up was achieved in 90% of patients at 180 days (6 months), and the overall postoperative morbidity was 10%. Within the 6 months, there was a single mortality event (10%) attributed to preexisting liver cell failure. The mean BMI preoperatively and postoperatively were 26.2 kg/m
conclusionsLaparoscopic reversal of gastric bypass is a complex surgery requiring a specialized surgical center, and it should be a last resort for intractable chronic symptoms. Patient education about relatively high morbidity and the possibility of dissatisfaction is crucial.
