Interventions

OTHERNutritional and Inflammatory Marker Evaluation

This is a prospective observational cohort study evaluating whether preoperative immune-nutritional markers-including Prognostic Nutritional Index (PNI), HALP score, Neutrophil-to-Lymphocyte Ratio (NLR), and C-Reactive Protein (CRP)-can predict early postoperative clinical outcomes (complication development, time to oral intake, mobilization, and length of hospital stay) in patients undergoing elective laparoscopic sleeve gastrectomy. No intervention or treatment is administered as part of this study. All data are collected from routine preoperative laboratory tests and standard postoperative clinical follow-up.
