Predictive Value of Nutritional and Inflammatory Indices for Postoperative Complications After Bariatric Surgery
Sponsor: G.Gennimatas General Hospital
Summary
Bariatric surgery is an effective treatment for severe obesity, but postoperative complications remain an important cause of morbidity. Several nutritional and inflammatory biomarkers derived from routine preoperative blood tests have been proposed as predictors of postoperative outcomes; however, their comparative value in bariatric surgery has not been fully established. This single-center retrospective cohort study will evaluate the ability of preoperative nutritional and inflammatory indices, including the Prognostic Nutritional Index (PNI), Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR), Systemic Immune-Inflammation Index (SII), Systemic Inflammation Response Index (SIRI), and C-reactive Protein-to-Albumin Ratio (CAR), to predict 30-day postoperative complications following bariatric surgery. The study aims to identify the most clinically useful biomarker for preoperative risk stratification and optimization of perioperative care.
