Objetive: To determine the changes in controlled attenuation parameter (CAP) levels in patients undergoing bariatric surgery. Method: The records of patients with obesity who underwent CAP measurement using the elastography prior to bariatric surgery and 6 months after it were reviewed and included. The normality of the data was analyzed and compared with the paired Student’s t test or Wilcoxon test. The association of the degree of pre- and postsurgical steatosis was analyzed using the χ2 test, considering p < 0.05 a statistically significant value. Results: 33 female patients with a mean age of 45.76 years ± 10.1 years were included, 17 were treated by gastric bypass and 16 with gastric sleeve. A reduction of 11 kg/m2 (10-12.5 kg/m2) was observed. The preoperative CAP levels were 282 ± 52 dB/m, and 6 months after bariatric surgery were 238 ± dB/m (p = 0.0006). The degree of steatosis decreased in 20 patients (60.7%), unchanged in 9 (27.3%) and increasing in 4 (12%). Conclusions: Bariatric surgery was shown to have a positive impact on reducing CAP levels in patients with obesity and metabolic dysfunction associated steatotic liver disease.
