Background: The satisfactory outcome in the surgical treatment of obesity must include, in addition to weight loss, a significant change in the pre-existing comorbidities and in the quality of life. Aim: To evaluate the quality of life in the late postoperative period in patients that underwent videolaparoscopic sleeve gastrectomy. Methods: It was applied the questionnaire "Bariatric Analysis and Reporting Outcome System" (BAROS) in patients that underwent videolaparoscopic sleeve gastrectomy. Results: A total of 47 patients between 21-60 years old were evaluated. The total mean of BMI before surgery was 43.06±5.87 kg/m². The average percentage of the reduction of excess weight after surgery was 85.46±23.6%. The score obtained by patients in the questionnaire about the improvement in the quality of life showed excellent (36.17%), very good (40.43%), good (21.28%) and reasonable (2.13%) results. There was clinical improvement after surgery in all comorbidities investigated. Conclusion: The weight loss was critical to improve the quality of life and offered the resolution or clinical improvement in all of the investigated comorbidities in patients submitted to sleeve gastrectomy.
