Comparative endoscopic ultrasound assessment of the gastric pouch after FundoRing-OAGB and OAGB.
Trial report in BMC surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04834635 (The Total Wrapping of the Fundus of the Gastric Excluded Part), which is not on this 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.

Abstract
backgroundThe highly effective one-anastomosis gastric bypass (OAGB) is one of the most widely performed procedures in bariatric/metabolic surgery. However, concerns remain regarding the association of OAGB with bile reflux and long-term weight regain. The FundoRing modification of OAGB (FundoRing-OAGB) incorporates the excluded stomach in a primary fundoplication designed to limit reflux and weight regain by exerting an anti-dilatation effect on the gastric pouch. PATIENTS AND
methodsThis comparative prospective post-hoc sub-study included 50 patients (25 per group) randomly selected from participants in a precursor randomized controlled trial (RCT). The sub-study aimed to assess and compare the anatomical integrity and volumetric parameters of the gastric pouch at 1 and 3 years using endoscopic ultrasound (EUS) in patients who had undergone OAGB with, or without, the FundoRing modification. Measurements included pouch diameter, volume, and wall thickness.
resultsAt 3 years, patients in the FundoRing-OAGB group (n = 21) had significantly lower pouch diameters (2.8 ± 0.23 cm vs. 3.41 ± 0.4 cm, p = 0.014) and volumes (60.39 ± 10.04 mL vs. 87.93 ± 25.79 mL, p < 0.001) compared to the OAGB group (n = 20). In the FundoRing-OAGB group, at year 3, pouch volume had increased 36.25% vs. an increase of 74.33% in the OAGB group (p < 0.001). Wall thickness and pouch length did not differ significantly.
conclusionThe FundoRing-OAGB modification exerted a significant anti-dilatation effect on the gastric pouch, as confirmed reliably by EUS. This effect may potentially correlate with better long-term weight maintenance; however, these clinical outcomes were not assessed in the present study. Large studies with long-term follow-up are needed to validate these findings and assess their clinical impact.
