BACKGROUND
Although Roux-en-Y gastric bypass (RYGBP) is one of the preferred bariatric procedures in obese individuals, the efficacy of this procedure in the setting of super-obesity [body mass index (BMI) >/=50] is unclear. The aim of this study was to compare the efficacy of laparoscopic (L) RYGBP to reverse metabolic syndrome, inflammation, and insulin resistance in super-obese women compared to morbidly obese women.
METHODS
Seventy-three consecutive women were enrolled in this prospective study. Anthropometric, metabolic, and inflammatory biological parameters were assessed in 18 super-obese and 55 morbidly obese women before LRYGBP and 1 year after surgery. Metabolic syndrome was diagnosed according to the International Diabetes Federation definition.
RESULTS
Before surgery, super-obese women had a higher BMI, fat mass, blood insulin, and HOMA1-IR than morbidly obese women. Both groups had similar serum levels of C-reactive protein and orosomucoid. The incidence of metabolic syndrome, type 2 diabetes, and increased liver enzymes was comparable in the two groups. One year after LRYGBP, metabolic syndrome, type 2 diabetes, metabolic and inflammatory biological parameters were improved in the whole study population. A similar degree of improvement was observed in super-obese and morbidly obese women, although BMI and fat mass were persistently higher in super-obese patients.
CONCLUSIONS
One year after surgery, LRYGBP was equally effective at reversing metabolic syndrome, inflammation, and insulin resistance in morbidly obese and super-obese women.
