Patients with a BMI of 40-45 kg/m2 undergoing laparoscopic sleeve gastrectomy showed significantly greater improvements in postoperative FEV1 (100.3% vs 95.7%, p=0.021) compared to those with a BMI of 45-50 kg/m2.

Does laparoscopic sleeve gastrectomy improve pulmonary functions and comorbidities differently in morbidly obese (BMI 40-45) compared to super obese (BMI 45-50) patients?

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.
Yormaz et al. (Mon,) conducted a cohort in Morbid obesity and super obesity (n=124). BMI 40-45 kg/m2 vs. BMI 45-50 kg/m2 was evaluated on Postoperative FEV1 (%) at 6 months (p=0.021). Patients with a BMI of 40-45 kg/m2 undergoing laparoscopic sleeve gastrectomy showed significantly greater improvements in postoperative FEV1 (100.3% vs 95.7%, p=0.021) compared to those with a BMI of 45-50 kg/m2.
