Using mean data from the validation study , the trend and directionality in risk was similar in the Roux-en-Y group .
In conclusion , bariatric surgery predicts long-term decreases in CV risk in obese patients
Obese patients have an increased prevalence of  cardiovascular ( CV ) risk factors , which improve with bariatric surgery , but whether bariatric surgery reduces long-term CV events remains ill defined .
Laparoscopic Roux-en-Y Gastric Bypass for Morbid Obesity: Results of our Learning Curve in 100 Consecutive Patients
Background : Morbid obesity requires life-long treatment , and bariatric surgery provides the best results . Among the bariatric procedures , laparoscopic Roux-en-Y gastric bypass ( LRYGBP ) has been considered to be superior . However , it requires advanced laparoscopic skills and a learning curve . We analyzed our results in an initial series of 100 patients . Methods : Data of 100 consecutive patients who underwent LRYGBP for morbid obesity in a 2.5-year period were prospect ively collected and analyzed with emphasis on results and complications . Results : Mean age was 31±5 years . There were 63 woman and 37 men . Preoperative BMI was 50±9 kg/m2 . 33 patients were considered super-obese ( BMI > 50 )  . Mean operative time was 3.8 ± 0.7 hours . Two patients required conversion to open surgery . Mean hospital stay was 6 days . Complications occurred in 10 patients . Mortality rate was 2 % . Excess body weight loss was as follows : 33 ± 8 % at 3 months ( n=92 ) , 47 ± 2 % at 6 months ( n=82 ) , 62 ± 4 % at 1 year ( n= 70 ) , 66 ± 5 % at 18 months ( n= 63 ) and 67 ± 8 % at 2 years ( n= 35 ) . There was significant improvement in several co-morbid conditions , such as diabetes and hypertension . Conclusion : LRYGBP is a reproducible technique . It requires the combination of bariatric and laparoscopic expertise
Using mean data from the validation study , the trend and directionality in risk was similar in the Roux-en-Y group .
