One anastomosis gastric bypass in children and adolescents: An international expert survey

Despite the growing popularity of one anastomosis gastric bypass (OAGB) as the third most commonly performed metabolic and bariatric surgery (MBS) procedure worldwide, concerns remain among MBS surgeons about performing OAGB in children and adolescents. This international expert survey was conducted to assess the perspectives of experts regarding the different aspects of OAGB specific to these patient groups. A total of 102 expert MBS surgeons from 41 countries were invited to participate in this survey, which took place between 24 May 2024, and 11 June 2024. The participating surgeons provided their responses through a 30-question online survey, employing a multiple-choice format. Approximately 6.85% of participants believe there should be no minimum age limit for OAGB and 26.5% of experts perform OAGB only in patients 18 years old and above. The experts define adherence to postoperative diet, patient cooperation, and managing family expectations as the main challenges encountered when performing OAGB in this population. About 92.2% of experts believe that consultation and follow-up by a paediatrician, as part of a multidisciplinary team (MDT), are essential before surgery. Also, 76.5% of experts believe that bone age should be determined in these age groups before OAGB. Despite the absence of strong evidence refuting the safety and efficacy of OAGB in children and adolescents, this survey revealed that there are still some concerns about the long-term safety and efficacy of OAGB in children and adolescents.
