    Purpose 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.

    Objective: In the present study, we aimed to retrospectively evaluate the preoperative characteristics, intraoperative and postoperative results of patients who underwent laparoscopic obesity surgeries. Methods: After obtaining the approval of the Ethics Committee, records of patients who underwent laparoscopic obesity surgery from January 2013 to December 2016 were reviewed. Demographic characteristics, medications used in anaesthesia and analgesia, the duration of recovery unit/hospital stay, intensive care unit/mechanical ventilation requirements and complications were recorded. Results: A total of 329 ASA II-III patients over a 3-year period were operated. Thiopental and propofol were administered at induction, sevoflurane, isoflurane and desflurane were administered for the maintenance, and vecuronium and rocuronium were administered to aid in neuromuscular blockage. The mean durations of recovery unit and hospital stays were 30.80 +/- 6.01 minutes and 4.27 +/- 1.68 days, respectively. The hypnotic agent, muscle relaxant or inhalation anaesthetics used did not have a significant effect on the duration of recovery unit and hospital stay. Mask ventilation and intubation were noted to be difficult in 5.5% and 8.5% of the cases, respectively. The presence of obstructive sleep apnoea syndrome and high body mass index and Mallampati scores significantly increased difficult mask ventilation and difficult intubation rates. Four patients were transferred to intensive care unit for close monitoring. Two patients were re-operated on, two patients had rhabdomyolysis, one patient had Wernicke's encephalopathy and two patients had peripheral neuropathy. Perioperative mortality did not occur in any patient. Conclusion: We believe that appropriate patient selection, the use of well-designed anaesthesia and surgical protocols play important roles in increasing the success rate of patient outcomes and early and late complications in laparoscopic obesity surgery.
