Bariatric surgery leads to marked and long-lasting weight reduction .
A large proportion of patients undergoing bariatric surgery have DM2 .
Glycemic control improves in the months after laparoscopic adjustable gastric b and ing , but it improves more rapidly and completely after laparoscopic Roux-en-Y gastric bypass surgery .
Thus , both types of surgery are capable of improving or even curing DM2 , but the mechanisms may differ

Early Results of Laparoscopic Biliopancreatic Diversion with Duodenal Switch: A Case Series of 40 Consecutive Patients
Background : Biliopancreatic diversion with duodenal switch ( BPD-DS ) is an operation which provides one of the greatest maintained weight losses of any bariatric procedure . We looked at the safety and efficacy of laparoscopic BPD-DS for morbid obesity . Methods : A 150 - 200 ml sleeve gastrectomy was created and anastomosed to the distal 250 cm of divided ileum . The median length of the common channel was 100 cm . All patients were prospect ively followed up to 12 months . Results : 40 consecutive patients underwent laparoscopic BPD-DS as a primary procedure for morbid obesity . Median patient body mass index ( BMI ) was 60 kg/m2 ( range 42 - 85 kg/m2 ) . Mean age was 43 ± 1 years ( ± SEM ) , with 12 males and 28 females . One patient was converted to  open laparotomy ( 2.5 % ) . Median operative time was 210 ± 9 minutes ( range 110 - 360 minutes ) with a significant correlation between BMI and operative time ( p = 0.04 ) . Median length of stay was 4 days ( range 3- 210 days ) . There was one 30-day mortality ( 2.5 % ) . Major morbidities occurred in 6 patients ( 15 % ) , including 1 anastomotic leak ( 2.5 % ) , 1 venous thrombosis ( 2.5 % ) , 4 staple-line hemorrhages ( 10 % ) and 1 subphrenic abscess ( 2.5 % ) . Median follow-up at 6 months ( range 1 - 12 months ) result ed in 46 % ± 2 % excess weight loss ( EWL ) and at 9 months 58 % ± 3 % EWL . Conclusion : Laparoscopic BPD-DS is a complex , yet feasible , procedure result ing in effective weight loss with an acceptable morbidity . A BMI > 65 was associated with increased morbidity and mortality . A long-term study is needed to confirm efficacy and proper patient selection
