Efficacy of sleeve gastrectomy as sole procedure in patients with clinically severe obesity (BMI ≤50 kg/m2)

SG is a reproducible procedure associated with significant weight reduction, resolution of obesity-related co-morbidities, and minor nutritional deficits at 5 years of follow-up. Laparoscopic SG can thus be safely used as the sole surgical treatment of clinically severe obesity (body mass index ≤50 kg/m2). The chief complication of postoperative leakage can be managed nonoperatively in most patients.
