Introduction: Bariatric surgery has seen a sharp increase over the past decade in France. The objective of this study was to describe trends in the rates of bariatric surgery and the various surgical techniques used in France between 2008 and 2014. Methods: A retrospective cross-sectional study was conducted using data from the Medical Information Systems Program (PMSI). Patients who underwent bariatric surgery in metropolitan France and in the overseas departments and regions in 2008 and 2014 were included. Their sociodemographic and anthropometric characteristics, as well as the types of surgical techniques used (adjustable gastric band (AGA), sleeve gastrectomy (SG), gastric bypass (GBP), biliopancreatic diversion (BPD), and calibrated vertical gastroplasty (CVG)), were analyzed. Results: The rate of bariatric surgery increased 2.6-fold in France between 2008 and 2014. In 2014, 45,474 patients, 65.6% of whom had morbid obesity, underwent bariatric surgery, with a higher proportion of women undergoing surgery at a younger age than men (40.1±11.9 years vs. 42.6±11.8 years; p<0.0001) and a lower BMI than men (33.3% of women with a BMI <40 vs. 25.4% of men; p<0.0001). SG (60.6%) was the most commonly performed procedure, followed by BPG (30.0%) and AGA (9.2%). Between 2008 and 2014, the rate of AGA use decreased sharply (55.1% in 2008 vs. 9.2% in 2014) in favor of SG (16.9% in 2008 vs. 60.6% in 2014). AGA placement was performed in significantly younger patients (AGA: 36.7±12.1 years; SG: 40.2±11.9 years; BPG: 42.3±11.4 years; p<0.0001). The use of SG and BPG increased with BMI. The rates of use of the various surgical techniques varied widely by region. Conclusion: The use of bariatric surgery increased significantly between 2008 and 2014, and the surgical techniques performed underwent major changes, with a clear rise in SG in recent years. Regional disparities in the surgical techniques performed raise questions about the value of developing a consensus on treatment selection.
