The comparison of pulmonary functions After the bariatric surgery In Morbid obeses Versus Super Obeses

Abstract

INTRODUCTION: Nowadays, the incidence of morbid obesity is one of the most common health problems in the world. Bariatric surgery is a procedure that lose excess weight, to heal comorbidities and to improve pulmonary functions in obeses. Laparoscopic sleeve gastrectomy is a bariatric procedure with succeed positive results for bariatric patients. Our aim was to compare postoperative respiratory outcomes in morbidly obese patients who have underwent Laparoscopic sleeve gastrectomy. METHODS: Consecutive 124 morbid obese patients who were underwent Laparoscopic sleeve gastrectomy were evaluated between the years of march 2014 to july 2016. Patients were divided into two groups A and B. Group A patients who have BMI between 40-45kg/m2 and group B patients who have BMI between 45-50kg/m2. FEV1, FVC, FEV1/FVC, MSV, DV/VO2, DV/VCO2, VO2peak results, body mass index, postoperative oxygen saturation and comorbidites, were compared between both groups. Student's t test,chi-square test was used for the variables and homogeneity in the patient group. RESULTS: The mean age values, respiratory function values in both groups were similar in preoperatively. In our postoperative results, there was a significant difference in the FEV1, FVC, FEV1/FVC, MSV, DV/VO2, DV/VCO2, VO2 peak ratios and also identified significant difference in resolution and improvement of comorbidities. DISCUSSION AND CONCLUSION: The results of the patients who underwent bariatric surgery and whose body mass index (BMI) was 40-45kg / m2 were statistically significant compared to other group. The improvement in pulmonary functions and the effect of correction of comorbidities are higher in the morbidly obese group with laparoscopic sleeve gastrectomy.
