Surgery results in greater improvement in weight loss outcomes and weight associated comorbidities compared with non-surgical interventions , regardless of the type of procedures used .
When compared with each other , certain procedures result ed in greater weight loss and improvements in comorbidities than others .
Outcomes were similar between RYGB and sleeve gastrectomy , and both of these procedures had better outcomes than adjustable gastric b and ing .
For people with very high BMI , biliopancreatic diversion with duodenal switch result ed in greater weight loss than RYGB .
Isolated sleeve gastrectomy led to better weight-loss outcomes than adjustable gastric b and ing after three years follow-up .
BACKGROUND Bariatric ( weight loss ) surgery for obesity is considered when other treatments have failed .
The effects of the available bariatric procedures compared with medical management and with each other are uncertain .

Maximal weight loss after banded and unbanded laparoscopic Roux-en-Y gastric bypass: a randomized controlled trial.
BACKGROUND Laparoscopic Roux-en-Y gastric bypass ( LRYGB )  leads to significant weight loss and correction of co-morbidities in most patients .  B and ed LRYGB was design ed to enhance weight loss and avoid weight regain . METHODS A r and omized controlled pilot trial was design ed to comparatively analyze the results and complications of  b and ed ( 6.5 cm ) and unb and ed LRYGB . The present study was an interim analysis focused on morbidity , mortality , and maximal weight loss . RESULTS The 60 patients were divided into 2 groups . Group 1 underwent unb and ed LRYGB ( n = 30 ) and group 2 underwent b and ed LRYGB ( n = 30 ) . No differences were found between the 2 groups in terms of age , gender , body mass index , or operative time . No significant differences were found in the percentage of excess weight loss and body mass index at 6 , 12 , and 24 months between the 2 groups . The frequency of complications was similar in both groups ; 1 patient required b and removal because of stenosis at the level of the mesh . CONCLUSION The weight loss pattern in both groups was similar at 1 and 2 years postoperatively . Proper assessment of weight maintenance and late weight regain will require longer follow-up
