Inflammatory and metabolic markers and comorbidities remission following sleeve gastrectomy: A single center one-year cohort study

Abstract

Background and aimObesity is a global concern with several health-related complications. Bariatric surgeries are major treatment options in patients with obesity and other comorbidities. This study aims to investigate the effects of sleeve gastrectomy on metabolic indexes, hyperechogenic liver changes, inflammatory state, diabetes, and other obesity-related comorbidities remission after the sleeve gastrectomy. MethodsThis prospective study was conducted on patients with obesity candidates for laparoscopic sleeve gastrectomy. Patients were followed for one year after the surgery. Comorbidities, metabolic and inflammatory parameters were assessed before and one- year after the surgery. Results137 patients (16 males, 44 in the DM group) underwent sleeve gastrectomy. One year after the study, obesity-related comorbidities improved significantly; diabetes had complete remission in 22.7% and partial remission in 63.6% of patients. Hyper-cholesterolemia, hyper-triglyceridemia, and hyper-uricemia also improved in 45.6%, 91.2%, and 69% of the patients. Metabolic syndrome indexes improved in 17.5% of the patients. Also, the prevalence of hyperechogenic changes in the liver has declined from 21% before the surgery to 1.5% after that. Based on logistic regression analysis, increased levels of HbA1C reduced the chance of diabetes remission by 0.9%. In comparison, every unit of increased BMI before the surgery improved the case of diabetes remission by 16%. ConclusionLaparoscopic sleeve gastrectomy is a safe and effective treatment option in patients with obesity and diabetes. Laparoscopic sleeve gastrectomy alleviates BMI and insulin resistance and effectively improves other obesity-related comorbidities such as Hypercholesterolemia, hyper-triglyceridemia, hyper-uricemia, and hyperechogenic changes of the liver. HbA1C and BMI before the surgery are notable predictors of diabetes remission within the first year after the surgery.
