We aimed to assess, over a 7-year period, the late adverse events after gastric bypass and sleeve gastrectomy compared with matched control groups.MethodsIn this nationwide, observational, population-based, cohort study, we used data extracted from the French National Health Insurance (Système National des Données de Santé) database. All patients undergoing gastric bypass or sleeve gastrectomy in France in 2009, except those who had undergone bariatric surgery in the previous 4 years before inclusion, were matched with control patients with obesity in terms of age, sex, BMI category, baseline antidiabetic therapy, and baseline insulin therapy. Exclusion criteria for the control group included cancer, pregnancy, chronic infectious disease, serious acute or chronic disease in 2008–09, or previous (2005–09) or forthcoming (2010–11) bariatric surgery. The incidence rate was calculated for each type of adverse event leading to inpatient hospital admission over a 7-year period; incidence rate ratios (with 95% CIs) were computed to compare the rate of complications among the bariatric surgery and control groups.
