Early Outcomes and Nutritional Scores in Bariatric Patients

The Relationship Between Preoperative Nutritional and Inflammatory Markers and Early Postoperative Clinical Outcomes in Patients Undergoing Bariatric Surgery

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.

Inclusion Criteria:

• Age between 18 and 65 years
• Body mass index (BMI) ≥ 35 kg/m²
• Scheduled for elective laparoscopic sleeve gastrectomy
• Availability of complete preoperative laboratory test results
• Signed informed consent

Exclusion Criteria:

• Severe hepatic or renal dysfunction
• Presence of active infection
• History of immunosuppressive therapy or hematologic malignancy
• Need for intensive care unit (ICU) admission within the first 72 hours postoperatively
• Preoperative administration of albumin or blood products
