    Effects of significant weight loss following bariatric surgery on red cell distribution width and mean platelet volume
    (2018) Altın, C.; Erol, V.; Yılmaz, M.; Bozkuş, Y.; Müderrisoğlu, H.
    Aim: Elevated red blood cell distribution width (RDW) and mean platelet volume (MPV) levels which are closely associated with chronic inflammation and platelet aggregation are suggested as independent predictors of obesity and cardiovascular diseases. However influence of significant weight loss following bariatric surgery on these parameters is unknown. Therefore we aimed to find out the effect of significant weight loss following laparoscopic sleeve gastrectomy (LSG) on RDW and MPV levels. Methods: The medical data of 98 morbid obese subjects (25 male, 73 female) who were operated between February 2015 and June 2017 according to indications of bariatric surgery in current guidelines including body mass index (BMI) >40 kg/m 2 or BMI= 35-40 kg/ m 2 with additional comorbidities were recorded. The difference between baseline and values at one year was expressed as a delta (Δ). Results: The mean age of our study population was 41.89±11.99 years and mean weight loss in one year after LSG was 45.41±13.13 kg (36.5%). BMI decreased from 46.60±7.11 kg/m 2 to 29.58±4.63 kg/m 2 . Compared to the baseline, significant decreases in RDW (14.61±1.69 % vs. 13.71±2.10 %; p<0.01) and MPV (8.63±1.45 vs. 7.92±1.24 fL, p<0.001) levels were found in the postoperative one-year values. In addition; ΔVKI was positively correlated with ΔRDW (r=0.343, p<0.01) and ΔMPV (r=0.322, p<0.01). Conclusion: We found that morbid obese subjects have significantly decreased RDW and MPV levels which are correlated to their weight loss in one-year follow-up after LSG. If we think that several factors may affect these parameters, conduction of further prospective large-scale studies are needed. © 2018, Logos Medical Publishing. All rights reserved.

    Retrospective Evaluation of Patients who Underwent Laparoscopic Bariatric Surgery
    (2018) Tuncali, Bahattin; Pekcan, Yonca Ozvardar; Ayhan, Asude; Erol, Varlik; Yilmaz, Tugba Han; Kayhan, Zeynep; 30140537
    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.
