Abstract:
Objective To explore the clinical factors that can be used to predict the early weight loss after laparoscopic sleeve gastrectomy(LSG).Methods The clinical data of 64 obese patients undergoing LSG in Peking Union Medical College Hospital from August 2015 to January 2018 were retrospectively analyzed.We analyzed the relationship between different clinical factors and early weight loss,determined the independent predictors based on models,and estimated their test power by using the receiver operating characteristic(ROC)curves.Results Correlation analysis indicated that preoperative body mass index(=0.000,=0.000,=0.000),waist circumference(WC)(=0.000,=0.000,=0.000),whole body fat volume(=0.000,=0.006,=0.003),homeostatic model assessment for insulin resistance(HOMA-IR)(=0.000,=0.000,=0.002),and hypersensitive C-reactive protein(hsCRP)(=0.004,=0.002,=0.025)were negatively correlated with excess weight loss percentage(EWL %) after 3,6 and 12 months.Also,hsCRP after 6 months showed negative correlation with EWL % after 1 year(=0.029).Binary Logistic regression analysis showed that WC was an independent predictor of early weight loss(=0.018).ROC analysis showed that when the optimal cutoff value is 142.5 cm for WC, index was highest,with a sensitivity of 80% and a specificity of 87%.Patients were further divided into low WC group and high WC group based on this optimal cutoff value.The low WC group had significantly higher EWL% than the high WC group 3 months(=6.677,=0.000),6 months(=6.157,=0.000),and 1 year(=4.006,=0.000)after surgery.The low WC group also had significantly lower hsCRP than high WC group 6 months after surgery(=-3.510,=0.000).HOMA-IR showed no significant difference between these two groups(=-0.821,=0.412).Conclusions WC is an independent predictor of weight loss early after LSG.The patients with low WC have better weight loss effectiveness.
