Hepatic Energy Fluxes in NASH and NAS Patients

Vertical Sleeve gastrectomy will be performed using five laparoscopic ports using a 40 French Bougie as a template. If a hiatal hernia is identified it will be repaired. This practice has greatly reduced postoperative reflux disease (see human subjects protection). As VSG for patients with a BMI 30.0-34.9 kg/m2 is not covered by insurance the University hospital will cover costs for up to 24 patients.
