Abstract

Bariatric surgery is an effective and safe option for treating obesity and associated comorbidities, with a complication rate ranging from 0.2% to 10%. This cross-sectional study evaluated 116 patients with a BMI over 40 who underwent bariatric surgery between May 2012 and December 2017, aiming to correlate preoperative spirometric parameters (FEV1, FVE, FEV1/FVC) with the development of postoperative complications. Among patients without complications, the median FVC was 88.21%, FEV was 86.43%, and FEV1/FVC was 98.94%. In patients with complications, the FVC was 78.56%, FEV1 was 75.53%, and FEV1/FVC was 96.95%. This study concluded that a reduction in FEV1 and FVC levels below 80% before bariatric surgery increased the risk of postoperative complications.
