In Brief:
In patients with type 2 diabetes (T2DM), laparoscopic Roux-en-Y gastric bypass resulted in 60% percent of excess body weight loss and 83% resolution of diabetes. Patients with T2DM < 5 years and mild disease had a much higher rate of resolution after surgery (95% and 97%, respectively) than patients with T2DM >10 years or severe disease (54% and 62%, respectively).
