Bariatric Surgery seems essential higher effectiveness than standard care to reduce weight in heavily overweight adults according to a review published in the August issue of obesity rates.
Raj Padwal, m.d., from the University of Alberta in Edmonton, Canada, and colleagues reviewed available literature until February 2009 assess the clinical efficacy and safety of bariatric surgery. A total of 31 long-term randomised controlled trials (RCTs) bariatric operations and/or standard care compare and involving mass index (BMI) between 42 and 58 kg / m 2,619 patients with an average age of 30 to 48 years and medium-sized body m² were included in the analysis. Change in BMI was the primary outcome measure and evidence-based parts with risk potential bias have been assessed.
The investigators found that when compared to standard care, BMI distinguished levels baseline up to one year in 15 trials with 1,103 participants. Mean that differences in the BMI for predominantly diversion procedures, including Jejunoileal bypass (-11. 4 kg / m m²), mini gastric bypass (-11. 3 kg / m m²), Biliopancreatic redirection (-11. 2 kg / m m²), the highest were and sleeve Gastrectomy (Celsius. 1 kg / m m²). An intermediate BMI change of -9. 0 kg/m square was seen for Roux-en-Y gastric bypass. Purely restrictive procedures, including gastroplasty horizontal, vertical banded gastroplasty, adjustable gastric band showing the least BMI differences. Adjustable gastric band had less serious adverse events as Roux-en-Y gastric bypass.
"We found that although long-term, adequately powered RCTs are lacking data from large, bariatric surgery much more effective than standard treatment for the treatment of severe obesity in adults seems", the authors write.
