RESUMO
Objective To investigate the effect of laparoscopic vertical banding gastroplasty (LVBG) on hepatic steatosis and metabolic abnormalities in morbidly obese patients one year after surgery.Methods A total of 11 morbidly obese patients with CT diagnosis of liver steatosis were studied to compare the following data before and one year after LVBG,including weight,body mass index(BMI),waist circumference,fasting plasma glucose(FPG),fasting insulin(FINS),insulin resistance index (HOMA IR), total cholesterol(TC),triglyceride(TG) and liver enzymes.Results With the loss of weight,BMI,waist circumference,FINS,HOMA IR and TG were declined,while liver CT values increased significantly after LVBG.The change of waist circumference was correlated with the change of FINS and that of HOMA IR significantly (P
RESUMO
To evaluate the effects and safety of laparoscopic vertical banding gastroplasty (LVBG) in morbid obese subjects. The clinical data related to the metabolism of glucose, lipids and obesity in 26 obese Chinese patients with LVBG one year before and after the surgery were analyzed. The results showed that 1 year after LVBG, there was a reduction of 22.98?14.27kg in body weight, 9.31?5.13kg/m 2 in BMI, and a reduction of 47.19%?31.17% of body over-weight (EWL%) in these patients. BMI, waist, waist hip ratio, systolic blood pressure, fasting insulin, insulin resistance based on HOMA, triglyceride, cholesterol/HDL, ALT and blood creatine were decreased with reduction of body weight and BMI after LVBG. Changes in BMI and EWL% were significantly correlated with those of fasting insulin and insulin resistance. It is suggested that LVBG is effective and safe for reducing body weight and improving metabolism in the markedly obese patients.
