Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The aim of the present multicentric prospective comparative study is to evaluate malabsorption and gut microbiota shift after laparoscopic RYGB vs MGB at 1 year.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Mini Gastric Bypass
Mini Gastric Bypass: The gastric pouch will be performed starting below the incisura angularis (transverse resection 4 cm) on the lesser curvature (18).Then the stomach will be transected against a 36 Fr bougie up to the gastro-esophageal junction Then 1/3 of the small bowel will be excluded (approximately 200cms) and 3.5-4 cm gastro-jejunostomy will be performed by linear stapler.
Mini Gastric Bypass
Standardization of the techniques will be guaranteed:
1. Mini Gastric Bypass Arm
2. Roux en Y Gastric Bypass arm All patients will have intraoperative measurement of the whole length of bowel from Treitz ligament to the ileocecal junction (expected range 6-8 m).The common limb will be therefore about 2/3 of total small bowel length.
Roux en Y Gastric Bypass
Roux en Y Gastric Bypass: The steps of the standard double loop RYGB technique will be followed (17). The gastric pouch will be created 7 cm from the gastro-esophageal junction to obtain a volume of 30-40 ml, and the length of the alimentary limb will be 150 cm and 3.5-4 cm gastro-jejunostomy will be performed by linear stapler. The length of the biliopancreatic limb will be from 65 to 75 cm beyond the ligament of Treitz. The lengths of both limbs should carefully measured with a graduated instrument. The mesenteric defects will be closed.
Roux en Y Gastric Bypass
Standardization of the techniques will be guaranteed:
1. Mini Gastric Bypass Arm
2. Roux en Y Gastric Bypass arm All patients will have intraoperative measurement of the whole length of bowel from Treitz ligament to the ileocecal junction (expected range 6-8 m).The common limb will be therefore about 2/3 of total small bowel length.
