Bariatric Surgery and Reactive Hypoglycemia

"Roux-en-Y Gastric Bypass This laparoscopic operation includes the division of the stomach in two parts. A proximal, smaller pouch (20-25 cc volume), is connected to the rest of the gastrointestinal tract through a gastro-jejunal anastomosis, whereas the distal gastric pouch is left behind but excluded from the transit of food.~An entero-entero anastomosis, with a Roux-en-Y type of reconstruction, allows the bile and pancreatic juices to mix with the nutrients at about 100-150 cm from the gastro-jejunal connection."

Sleeve gastrectomy Laparoscopic SG involves a longitudinal resection of the stomach on the greater curvature from the antrum starting opposite of the nerve of Latarjet up to the angle of His The final gastric volume is about 100 mL.
