Measure
Non-Obese (NO)
Patients with a BMI \< 29.9 scheduled for clinically indicated laparoscopic abdominal surgery.
Morbidly Obese (MO)
Patients with a BMI \> 40.0 scheduled for clinically indicated laparoscopic abdominal surgery.
Super-morbidly Obese (SMO)
Patients with a BMI \> 50.0 scheduled for clinically indicated laparoscopic abdominal surgery. 10 subjects of the original 30 subjects enrolled into this group received a second bariatric procedure. The remaining 20 subjects of the original 30 subjects did not continue on to the second phase (initial bariatric surgery) of the study.
