Laparoscopic Gastric Bypass as Metabolic Surgery in Obesity Class 1

The LGBP was performed using a classic Roux-en-Y procedure. Briefly, a gastric pouch of 30-50 cc was constructed with an antecolic calibrated gastro-jejunal anastomosis (mechanical anastomosis using a 2.5 mm load). The biliary and alimentary limbs measured ≈70 cm and ≈150 cm, respectively, and the jejuno-jejunal anastomosis was also performed in a latero-lateral fashion (mechanical anastomosis using a 2.5 mm load). Mesenteric defects were closed with running non-absorbable sutures and the omentum was divided in every case
