Results of Laparoscopic Sleeve Gastrectomy in 541 Consecutive Patients with Low Baseline Body Mass Index (30-35kg/m2).

Abstract

Laparoscopic sleeve gastrectomy (LSG) is currently the leading bariatric procedure and targets, among other obesity classes, patients with BMI 30-35kg/m2, which are reaching alarming proportions. Between February 2010 and August 2015, data on 541 consecutive patients with BMI 30-35kg/m2 undergoing LSG were prospectively collected and analyzed. Mean age was 32 ± 8years (13-65) and 419 (77.4%) were women. Preoperative weight was 92.0 ± 8.8kg (65-121) and BMI was 32.6 ± 1.5kg/m2 (30-35). Comorbidities were detected in 210 (39%) patients. Operative time was 74 ± 12min (40-110) and postoperative stay was 1.7 ± 0.22days (1-3). There were no deaths, leaks, abscesses or strictures and the rate of hemorrhage was 1.2%. At 1year, 98% were followed and BMI decreased to 24.7 ± 1.6, the percentage of total weight loss (% TWL) was 24.1 ± 4.7 while the percentage of excess BMI loss (%EBMIL) reached 106.1 ± 24.1. At 5years, 76% of followed patients achieved a ≥50% EBMIL. With appropriate surgical expertise, LSG in patients with BMI 30-35kg/m2 achieved excellent outcomes with a zero fistula rate.
