Summary

This prospective observational study aims to evaluate whether preoperative immune-nutritional markers-specifically the Prognostic Nutritional Index (PNI), HALP score, Neutrophil-to-Lymphocyte Ratio (NLR), and C-Reactive Protein (CRP)-can predict early postoperative clinical outcomes such as time to oral intake, mobilization, complications, and length of hospital stay in patients undergoing elective laparoscopic sleeve gastrectomy.

Conditions

• Postoperative Complications
• Preoperative Nutritional Markers

Type	Name	Description
OTHER	Nutritional 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.
