Effectiveness of the Modified Hemoglobin, Albumin, Lymphocyte, and Platelet Score in Predicting Weight Loss After Laparoscopic Sleeve Gastrectomy.

The overexpression of proinflammatory cytokines in obesity has suggested an association between obesity and inflammation. In this study, we aimed to predict the success of weight loss at the end of the first year of patients who underwent laparoscopic sleeve gastrectomy (LSG) for morbid obesity using hemoglobin, albumin, lymphocyte, and platelet (HALP) score and modified HALP (m-HALP) score. Patients were divided into two groups according to the success of weight loss. The groups were compared in terms of HALP score, m-HALP score, demographic parameters, and preoperative laboratory tests. The diagnostic performance measurements of the m-HALP score were calculated. In addition, logistic regression analysis was performed for the factors affecting weight loss in the first year after LSG. Seventy-two patients were evaluated. The median m-HALP score of the patients with an excess weight loss percentage (EWL%) <60 threshold was 562 (416.6-891.9), the median m-HALP score of the patients with an EWL% above the 60 threshold was 394.3 (347.9-543), and the difference between the outcome groups was significant ( = .002).The accuracy of m-HALP score in identifying the patients whose EWL would be <60% 1 year after the surgery was 63.9 (95% confidence interval = 51.7-74.9). This study showed that the m-HALP score is effective in predicting weight loss after bariatric surgery.
