Abstract    One anastomosis gastric bypass (OAGB) has achieved a good balance between effectiveness and safety and has shown a vigorous growth trend in recent years. Bile reflux and theoretical potential cancer risk after OAGB are ongoing controversies in its past, present, and future. The most common cause of revision after OAGB is severe malnutrition, which needs to be taken attention to by bariatric and metabolic surgeons. Strictly following the surgical indications of the guidelines and evaluating the suitability of recommending OAGB according to the specific situation of the patient, while avoiding the misconception of excessively aggressive bypass small intestine length, are the effective strategy to safely perform OAGB in clinical practice at this stage.
