Impact of vertical banded gastroplasty on body weight, insulin resistance, adipocytokine, inflammation and metabolic syndrome markers in morbidly obese patients.

INTRODUCTION: Diet, exercise, and pharmacological therapy have been shown to be unsatisfactory treatments for severe obesity in the long term. Bariatric surgery is the most effective means to achieve weight loss in morbidly obese subjects. The aim of this study was to evaluate the action of a number of adipocytokines, as well as the metabolic syndrome parameters of obese patients, before and after vertical banded gastroplasty (VBG).
MATERIAL AND METHODS: The test subjects comprised eight males and 20 females (total 28 patients) aged from 20 to 59 years (43.7 ± 10.0) with simple obesity and the presence of metabolic syndrome, both before and 3, 6, 12, and 24 months after bariatric surgery (six patients were also checked after 36 and 48 months).
RESULTS: After surgical treatment (at 24 months), the values of body weight, BMI, waist circumference, blood pressure (RR-S, RR-D), HOMA-IR and blood concentrations of CRP, TG, IRI, AUC-IRI, and AUC-GLU gradually decreased. We did not observe any significant differences of fasting glucose, leptin, total cholesterol and LDL-cholesterol concentrations before or after surgery. The blood levels of HDL, adiponectin, resistin, and ghrelin gradually increased after treatment.
CONCLUSIONS: The significant decrease of body weight after vertical banded gastroplasty, as well as improvement of the main metabolic syndrome parameters and some adipocytokine blood levels, indicate the use of bariatric surgery as a valuable method of treating morbidly obese patients.
