Item Assessment of Carotid Artery Distensibility and Elasticity After Laparoscopic Sleeve Gastrectomy: a Prospective Study(2020) Gunesli, Aylin; Yilmaz, Mustafa; Altin, Cihan; Gezmis, Esin; Yabanoglu, Hakan; Erol, Varlik; 0000-0002-2557-9579; 0000-0002-8337-6905; 0000-0002-1161-3369; 0000-0002-1001-6028; 0000-0003-0268-8999; 32813160; S-6973-2016; AAK-3065-2021; AAJ-7865-2021; AAE-8301-2021; AAK-2011-2021Purpose Although it is well known that obesity increases the risk of atherosclerosis in carotid arteries, it is not clear whether this risk changes after obesity surgery. The aim of this study was to investigate whether weight reduction with a laparoscopic sleeve gastrectomy (LSG) has any effect on distensibility and elasticity which show subclinical atherosclerosis in the carotid arteries of obese individuals. Materials and Methods This prospective study included 130 patients (body mass index (BMI) 48.21 +/- 6.97 kg/m(2)) who underwent LSG. The patients were followed up for 1 year. Comparisons were made of the distensibiliy and elasticity values calculated preoperatively and at 1, 3, 6, and 12 months, postoperatively. Results There was a statistically significant increase in distensibility and elasticity values from baseline to 1, 3, 6, and 12 months postoperatively (p < 0.001 for both comparisons). The multiple linear regression analysis was used to find the variables affecting both distensibility and elasticity. According to the results, the presence of BMI decreases distensibility percentage change level by 0.38 units (beta= - 0.38, 95% CI - 0.51;- 0.25,p < 0.001). The presence of fasting plasma glucose decreases elasticity percentage change level by 0.20 units. (beta= - 0.20, 95% CI - 0.39; - 0.01,p = 0.037). Conclusion Carotid artery distensibility and elasticity values increase after LSG, and this change could be caused by the change in metabolic parameters and heart geometry. These results may indirectly suggest that subclinical atherosclerosis in carotid arteries has decreased after obesity surgery.Item Change of respiratory functions, the STOP-Bang questionnaire, and Epworth sleepiness scale after bariatric surgery(2020) Kara, Sibel; Habesoglu, Mehmet Ali; Yabanoglu, Hakan; 33055387INTRODUCTION AND OBJECTIVE: Obesity is a highly morbid and fatal syndrome that reduces respiratory function. Obstructive sleep apnea syndrome (OSAS) is a common sleep disorder in morbid obesity. Herein, we aimed to determine how respiratory function tests changed over time after bariatric surgery and to assess non-PSG (polysomnography) tests, namely STOP-Bang questionnaire and Epworth sleepiness tests, for predicting OSAS risk. METHOD: This retrospectively conducted study enrolled 35 patients who underwent bariatric surgery. Patients were divided into three groups formed on the basis of time passed after surgery (1, 2, or 3 years). Preoperative and postoperative respiratory function test parameters assessed by spirometry, body mass index (BMI), STOP-Bang questionnaire, and Epworth sleepiness test scores were recorded. RESULTS: Twenty-four (68.6%) patients were female, 11 (31.4%) male. The mean age was 36.5 +/- 10.5 years. Postoperative weight loss of the study groups was 26% p=0.001, 23.6% p=0.002 and 25.9% p=0.005. Reductions in BMI were 32 kg/m(2) p=0.001, 34.5 kg/m(2) p=0.002, 35.8 kg/m(2) p=0.005 respectively. Postoperative FVC (440 ml, 390 ml, 430 ml p = 0.005) and FEV1 (220 ml p = 0.005, 250 ml p = 0.004, 214 ml p = 0.005) increased in all three groups. STOP-Bang questionnaire and Epworth sleepiness scale scores significantly decreased after weight loss compared to preoperative period in all the study groups. CONCLUSION: We showed that FVC and FEV1 increased in the short and long term after weight loss by bariatric surgery; we also found that STOP-Bang questionnaire and Epworth sleepiness scale scores decreased postoperatively. These tests may be helpful to assess OSAS risk before and after surgery.
