Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective observational study enrolling adults with BMI ≥35 who are scheduled for elective laparoscopic sleeve gastrectomy at Istinye University in Istanbul. Investigators will collect preoperative laboratory data to calculate PNI, HALP score, NLR, and CRP and then track early postoperative outcomes including time to oral intake, mobilization, complications, and length of hospital stay. Key exclusions include severe hepatic or renal dysfunction, active infection, history of immunosuppressive therapy or hematologic malignancy, perioperative albumin or blood product use, and need for ICU admission within the first 72 hours. Associations between preoperative marker levels and early clinical outcomes will be analyzed using regression models and predictive performance metrics.
