Patients were randomly allocated a simple or complex carbohydrate drink two hours before laparoscopic colectomy. Intra-operative insulin sensitivity was preserved equally in both groups. Similarly there was no difference in hepatic insulin resistance or fasting blood glucose in either group up to day three after surgery.
