Abstract: Summary This study aims to give a comprehensive overview of the one anastomosis gastric bypass (OAGB) and Roux‐en‐Y gastric bypass (RYGB) during 5 years of follow‐up in terms of weight loss, the remission of obesity‐associated diseases and complications. We performed a retrospective cohort study, with a 1:1 propensity‐score matched (PSM) comparison between all adult patients who underwent a primary OAGB or RYGB in 2016. Patients with a body mass index (BMI) ≥50 kg/m 2 were excluded. In total, 372 patients underwent OAGB and 113 patients RYGB. After performing a 1:1 PSM, we obtained two nearly identical cohorts of 113 patients. After OAGB, the percentage of total weight loss (%TWL) was significantly higher during 5 years of follow‐up. Also, more patients after OAGB had a successful weight loss (TWL > 20%) after 5 years (86% vs. 72%; p = .019). The remission of obesity‐associated diseases and short‐term complications did not differ between both procedures. Persistent reflux was the reason for conversion to RYGB in 11.3% of the patients after OAGB. More internal herniations were seen after RYGB (10.4% vs. 1.9%; p = .010). Overall, the proportion of patients with major mid‐term complications did not differ between both procedures. In conclusion, OAGB resulted in more weight reduction and especially fewer patients with insufficient weight loss during 5 years of follow‐up, while remission of obesity‐associated diseases remained the same.
