Changes in use and hospital outcomes of bariatric surgery in Spain (2016–2022): analysis of the role of type 2 diabetes using propensity score matching
Authors' conclusion
Between 2016 and 2022, bariatric surgery procedures performed in Spain increased in patients with and without T2DM. More interventions were performed on patients with T2DM than on patients without T2DM. RYGB was the most common procedure in patients with T2DM. The presence of T2DM was associated with more severity after SG.

- Incidence of RYGB and SG increased significantly between 2016 and 2022
- P < 0.001
- RYGBs in patients with T2DM
- 31.57%
- SG patients with T2DM
- 25.53%
