Impact de l’âge sur les résultats de la chirurgie bariatrique : étude rétrospective d’une cohorte de patients opérés sur l’Hôpital d’Instruction des Armées Robert Picqué

Abstract : Background : Obesity is a chronic disease associated with an increase in morbidity and mortality that affects 15% of the French population. Bariatric surgery is part of the treatment of obesity, recommended by the HAS in second intention. The purpose of our work was to evaluate the impact of the age of the patients at the time of their intervention on the mediumterm outcomes of bariatric surgery. Methods : We retrospectively analyzed the data of obese patients operated on a bariatric surgery on HIA Robert PICQUÉ between 2009 and 2015. These patients were divided into 4 different age groups: <30 years old, 30 to 40 yo, 40 to 50 yo and ≥ 50 yo. For the entire study population and for each of the four subgroups of patients, we assessed the weight outcomes (excess weight loss and body mass index), comorbidities (hypertension, diabetes and sleep disorders) and morbidity for comparison purposes over a period of 1 year after the intervention. Results : 140 patients aged 20 to 69 years were included in our study. The demographic analysis of the 4 subgroups of patients did not show any significant differences in preoperative BMI, sex ratio or operative technique. The EWL at 1 year was significantly different between the four groups, more important for patients aged 30 to 40 (97.6%) than for those over 50 (78.2%). The results in groups 1 and 3 were intermediate. Regarding comorbidities or postoperative morbidity and mortality, we did not show a significant difference between the 4 groups. Conclusion : Age is a factor influencing the weight results of bariatric surgery. Patients over 50 years of age have significantly lower weight results than patients aged 30 to 40 years. On the other hand, age has no influence on the evolution of the associated comorbidities or postoperative morbidity and mortality.
