What about the Laparoscopic Sleeve Gastrectomy (LSG) or Vertical Sleeve Gastrectomy (VSG)?
The laparoscopic sleeve gastrectomy (LSG) procedure has been utilized as a first-stage bariatric procedure to reduce surgical risk in very heavy patients (over 200 kg) by induction of weight loss and this may be its most useful application at the present time. The mechanism of weight loss and resultant comorbidity improvement seen following LSG may be related to reducing the capacity to eat or to neurohumoral changes observed following the procedure because most of the stomach is removed or some other unidentified factor(s). There are currently 15 published scientific reports describing short-term outcomes in 775 patients after sleeve gastrectomy. The reports describe surgical treatment of patients with preoperative body mass index ranging from 35 to 69 kg/m2and excess weight loss ranging from 33% to 83%. Comorbidity resolution 12 to 24 months after sleeve gastrectomy has been reported in 345 patients demonstrating resolution/improvement of diabetes, hypertension, hyperlipidemia, and s
