AbstractLaparoscopic adjustable gastric banding (LAGB) has become a standard restrictive procedure in the USA for the treatment of severe obesity (body mass index, BMI > 35 kg/m(2)). Mildly obese individuals (BMI < 35 kg/m(2)) are also at increased risk from obesity-related conditions. Recently, an FDA panel supported its use in this subgroup. We compared the perioperative outcomes of LAGB in mildly and severely obese. Thirty consecutive patients (mildly obese n=10; severely obese n=20) that underwent preoperative medical weight loss followed by LAGB procedures were prospectively evaluated. Outcome variables included: operative room (OR) time, intraoperative estimated blood loss (EBL), length of hospital (LOS), and intensive care unit (ICU) stay, reoperations, readmissions, 30-day morbidity and mortality. Demographic data was comparable between groups. BMI was significantly higher in the severely obese compared to mildly obese (44.0 ± 5 vs. 33.6 ± 1 kg/m(2)). OR time, EBL, LOS, and ICU admissions were similar between BMI groups. There were no reoperations or 30-day mortality in either group. Minor morbidity was only observed in the severely obese group. BMI correlated with OR time and EBL. In mildly obese, LAGB is as safe as in the severely obese with no perioperative morbidity. The perioperative outcomes and hospital resource utilization are comparable between BMI groups. Lower BMI is associated with lower operative times and blood loss.
