Extended Versus Standard Pouch in Roux-en-Y Gastric Bypass: Five To Nine Year Follow-Up Results of a Randomized Controlled Trial.
Trial report 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
backgroundMetabolic bariatric surgery (MBS) such as the Roux-en-Y gastric bypass (RYGB) is effective in the treatment of obesity. However, not every patient achieves optimal clinical response and recurrent weight gain remains a concern. Hypothetically, a narrow longer pouch could lead to better results by preventing pouch dilatation and slowing down gastric emptying rates. The aim of this study is to evaluate the effect of an extended pouch gastric bypass (EP-RYGB) on weight loss and quality of life 5 to9years (median 109 months [104-116]) postoperatively.
methodsFollow-up study of a single-blinded RCT including 62 patients who underwent a standard Roux-en-Y gastric bypass (S-RYGB, n = 30) versus EP-RYGB (n = 32) between September 2014 and October 2015. Outcomes on weight loss, obesity related complications, health-related quality of life (HRQoL), and gastro-intestinal symptomswere compared between S-RYGB and EP-RYGB.
resultsMean total weight loss (%TWL) was higher in EP-RYGB compared to S-RYGB (26.1 ± 11.2%, versus 24.1 ± 10.1%) although not statistically significant. More patients in the S-RYGB group tended to experience recurrent weight gain compared to EP-RYGB (70% versus 47%, p = 0.07). HRQoL and gastro-intestinal symptoms were comparable between groups (p > 0.05 for all).
conclusionEP-RYGB results in slightly better weight loss outcomes and similar HrQoL compared to S-RYGB 5 to 9 years postoperatively. However, due to loss to follow up, the current study is underpowered and a definitive long term advantage of EP-RYGB cannot be concluded.
