Purpose: To investigate the metabolic improvements in obese patients with different serum triglyceride (TG) levels after laparoscopic sleeve gastrectomy (LSG).

Methods: 118 severely obese patients [body mass index (BMI)>35kg/m2] underwent LSG with complete information of follow-up for 3 and 6 months were analyzed. Patients were divided into two groups based on their different baseline serum levels of TG.

Results: The metabolic parameters (BMI, NC, WC, HC, WHR, blood pressure, liver function, blood glucose, blood lipids, insulin resistance, HbA1c, and UA) of the normal and higher TG groups were significantly improved after surgery. Patients with normal TG had better improvement in BMI and WC compared with higher TG patients in both 3 and 6 months. After adjustment for age and gender, ΔWC positively correlated with ΔBMI (r=0.446, P<0.001), creatinine level (ΔCr, r=0.365, P=0.005) in the normal group in 3 months follow-up. In 6 months after LSG, ΔWC positively correlated with ΔBMI (r=0.657, P<0.001) and ΔCr (r=0.442, P=0.009) while ΔWC negatively correlated with the change in eGFR level (ΔeGFR, r=-0.374, P=0.009) in the normal group. In addition, multivariate linear regression analysis showed that decreased ΔWC levels significantly correlated with ΔBMI (β=1.333, R2 =0.259, P<0.001) and ΔCr (β=0.336, R2 =0.160, P=0.005) both in 3 months and 6 months after LSG.

Conclusion: LSG can effectively improve metabolic disorders. Moreover, there were differences in weight loss between the normal and high TG groups after LSG, indicating that the baseline TG level can be used to predict short-term weight loss after LSG.
