  • The investigators aim to determine the clinical and metabolic effects of sleeve gastrectomy with or without omentectomy in the treatment of morbid obesity.
  • The investigators hypothesize that the endocrine suppression of ghrelin (appetite hormone)and resistin (insulin antagonist) provided by sleeve gastrectomy and omentectomy (omentum or intra-abdominal fat removal) will provide clinical and metabolic benefits for morbidly obese patients.
