Roux-en-Y gastric bypass after successful weight loss with a laparoscopic adjustable gastric band: rationales and early outcomes in patients of body mass index<35 kg/m2

Morbidity resulting from conversion of LAGB to RYGB in patients with BMI <35 kg/m2 is similar to that seen in the BMI>35 kg/m2 population. The procedure is technically challenging and morbidity rates are higher than those reported for surgically 'naïve' patients. It is recommended that this procedure be undertaken by appropriately trained surgeons in high-volume bariatric centers to optimize safety and outcomes.
