ObjectiveTo investigate whether HALP score [hemoglobin, albumin, lymphocyte (LY), platelet] can predict weight loss in patients undergoing sleeve gastrectomy.Study DesignA cohort study.Place And Duration Of StudyDepartment of General Surgery, Balıkesir University, Turkey from July 2019 to July 2020.MethodologyOne-year data of 64 patients, who underwent sleeve gastrectomy due to obesity were included for the analysis. The cut-off value of HALP score was calculated to be 41.2971. Those below the cut-off value were classified into Group 1 (low HALP score) and those above it were classified into Group 2 (high HALP score). Preoperative and postoperative body mass index (BMI), hemotologic parameters, platelet/LY ratios (PLR), and neutrophil/LY ratios (NLR), were compared. According to the percentage of excess BMI loss, patients were divided into 3 groups: Group A (≤40%), Group B (40%-60%), Group C (≥60%).ResultsThe decrease in postoperative BMI was significantly high in Group 2 (p<0.001). There was a significant difference between the groups in terms of percentage change of hemoglobin (p=0.012). The increase in postoperative LY value and decrease in postoperative PLR value were significantly high in Group 1 (p=0.019, p=0.003). Furthermore, patient distribution was significantly different among groups A, B, and C (p <0.001). Comparison of groups showed a significant difference between groups A and B and between groups A and C, but not between groups B and C (p=0.006, p<0.001, and p=0.192, respectively).ConclusionIn patients with high HALP scores, the rate of weight loss was higher, and most of their laboratory parameters were improved compared to those patients with low HALP scores. Key Words: Body mass index, Sleeve gastrectomy, obesity, Weight loss, HAIP score.
