Abstract
PURPOSE: The long-term impact of bariatric surgery on the remission of type 2 diabetes (T2DM) remains to be clarified through large nationally representative cohorts. The objectives were to determine the incidence of T2DM remission and relapse after bariatric surgery, to determine the factors associated with remission and to establish a profile for patients at risk for relapse. MATERIALS AND METHODS: We conducted a population-based cohort study using data from the French national health insurance database (Systeme national des données de santé [SNDS]). We had access to exhaustive regional data between 2013 and 2017 and to a national representative sample of the French population (EGB) from 2008 to 2018. Patients were included if they were adults and diabetics with incidental bariatric surgery. RESULTS: This study shows that 50% of patients are in remission from diabetes after bariatric surgery within a median of 2 to 4 months. Diabetes relapse was observed in 13-20% within 10 years. The factors favouring remission already described were noted (non-insulin-dependent diabetes) and original factors were also identified, in particular the advantage of bypass surgery over sleeve gastrectomy, with more remissions and fewer relapses. CONCLUSION: This study highlights a 50% prevalence of remission and a low prevalence of relapse. There are non-modifiable risk factors for remission and relapse (characteristics of diabetes, age, lipid-lowering therapy) and modifiable factors (type of surgery). Identifying these factors is essential for optimal management of patients. Additional data are essential to confirm the results of our analysis of the factors associated with relapse.
