Bariatric surgeries in the Brazilian public health system from 2012 to 2022: descriptive study of hospitalizations in the state of Paraná

HIGHLIGHTS

  • Obesity is most prevalent among women, aged between 30 and 49 years old, and of white ethnicity.
  • Between 2012 and 2022, the number of bariatric surgeries performed in Paraná increased significantly, with 97.6% of all surgeries utilizing primarily the Roux-Y technique.
  • Surgical approaches for the treatment of obesity and its related conditions, such as type II diabetes, yield significantly better rates of remission.

 

ABSTRACT – Background –

Obesity is a chronic health condition with a multifactorial etiology, resulting from the interplay of genetic, environmental, and behavioral factors leading to an energy imbalance. Objective – To characterize hospitalizations for bariatric surgeries through the Brazilian Unified Health System (SUS) in the state of Paraná from 2012 to 2022. Methods – This is a descriptive and retrospective study, utilizing a time series design, based on secondary data. Public data from the SUS Hospital Information System for the period from 2012 to 2022 were consulted, focusing on the population of obese patients undergoing bariatric surgery. Results – In Paraná, concerning SUS procedures data from 2012 to 2022, 39,793 hospitalizations for bariatric surgeries were observed. Among the five modalities, Roux-en-Y gastric bypass predominated with 38,849 hospitalizations (97.6%), showing a lower mortality rate. Conclusion – The research highlights a notable variation in costs, emphasizing the importance of economic evaluation. The correlation between obesity and diabetes underscores the complexity of the situation, justifying the superiority of surgical treatment in comorbidity remission. The study reveals a decline in bariatric surgeries in 2020, coinciding with the pandemic, and alerts to the increased vulnerability of obese patients to SARS-CoV-2.
