Conversion of One Anastomosis Gastric Bypass (OAGB) to Roux-en-Y Gastric Bypass (RYGB) for Biliary Reflux Resistant to Medical Treatment: Lessons Learned from a Retrospective Series of 2780 Consecutive Patients Undergoing OAGB.
Article in Obesity surgery, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 41 papers, 3 of them syntheses that pooled it.
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
backgroundBiliary reflux resistant to medical treatment has an incidence of 0.6-10% after one anastomosis gastric bypass (OAGB) and may be a reason for revisional surgery. The aim of this study is to report the results of a single-institution series of patients who underwent conversion from OAGB to Roux-en-Y gastric bypass (RYGB) for biliary reflux.
methodsData of OAGB patients converted to RYGB between May 2010 and December 2017 were prospectively collected and retrospectively analyzed. The afferent limb was sectioned proximally to the gastrojejunal anastomosis. A jejuno-jejunal latero-lateral anastomosis was performed between the biliary and alimentary limb. The final RYGB had an alimentary limb of 100 cm and a biliary limb of 150 cm.
resultsDuring the study period, 2780 patients underwent OAGB. A total of 32 patients (1.2%) underwent conversion from OAGB to RYGB for biliary reflux, at a mean of 30.3 months from OAGB. Mean weight before RYGB was 70.6 kg, and mean body mass index BMI was 26 kg/m
conclusionsBiliary reflux although rare can complicate OAGB. RYGB is a safe and feasible technique of revision in this case. A shorter length of the afferent limb during the initial operation facilitates the revision.
