Clinical Evaluation of the Medium-Term Efficacy of Laparoscopic Sleeve Gastrectomy against Obstructive Sleep Apnea-Hypopnea Syndrome in Obese Patients

Abstract

Objective. This study was designed to evaluate the efficacy of laparoscopic sleeve gastrectomy (LSG) for obstructive sleep apnea-hypopnea syndrome (OSAHS) in obese individuals and identify the related factors affecting its efficacy. Methods. The clinical and follow-up data of 37 obese patients with OSAHS who underwent LSG in the Laparoscopic Surgery Department of Zibo Central Hospital from January 2017 to July 2018 were analyzed retrospectively. The effect of this operation on patients' weight and OSAHS was studied, and the factors affecting weight and OSAHS were examined through univariate and multivariate logistic regression analysis. Results. Over 12 months of regular postoperative follow-up with the 37 patients, their body mass index (BMI) decreased, and the percentage of excess weight loss (EWL%) reached 73.2%. Additionally, the rate of successful OSAHS treatment reached 91.89%, and the apnea-hypopnea index (AHI) and lowest arterial oxygen saturation (LSaO2) increased significantly. Univariate logistic regression analysis showed that gender, weight, EWL%, and smoking affected the efficacy of LSG against OSAHS (P<0.05). EWL% and smoking were independent factors that helped determine the efficacy of LSG against morbid obesity (P<0.05). Conclusion. LSG can effectively help obese patients lose weight and show medium-term efficacy against OSAHS in obese people. Smoking and EWL% were found to be the factors determining the efficacy of LSG.
