Brief Summary

Bariatric surgery is the most effective treatment to achieve type 2 Diabetes Mellitus (DM) remission in patients with severe obesity. However, there is little evidence of the effectiveness and pathophysiological mechanisms involved in metabolic improvement after hypoabsortive tecniques such as duodenal switch (DS), single anastomosis duodenal switch (SADI-S) or minigastric bypass (MGB). We have designed a randomized study to compare type 2 diabetes remission after the 3 bariatric procedures in patients with severe obesity (BMI \> 45kg/m2) and to study the implication of gastrointestinal hormones, bile acids and gut microbiota in metabolic improvement in each procedure.

Study Arms (3)

Duodenal switch

ACTIVE COMPARATOR

The restrictive portion of the surgery involves removing approximately 70% of the stomach (along the greater curvature) and most of the duodenum. The malabsorptive portion of the surgery reroutes a lengthy portion of the small intestine, creating two separate pathways and one common channel.The common channel is 200 cm and 100m the alimentary limb.

Procedure: Duodenal Switch

SADI-S

ACTIVE COMPARATOR

Creation of a sleeve gastrectomy (SG) and a duodenal-ileal anastomosis with preservation of the pylorus, jejunal exclusion and a total common-alimentary limb, originally measuring 200 cm and later standardized to 300 cm to reduce the risk of nutritional deficiencies.

Procedure: SADI-S

Minigastric bypass

ACTIVE COMPARATOR

Creation of a gastric pouch similar to Sleeve gastrectomy and the small bowel is run to 200 cm distal to Treitz' ligament and then anastomosed antecolic end-to-side to the gastric pouch.

Procedure: Minigastric Bypass

Interventions

Classic Duodenal Switch

Duodenal switch
SADI-SPROCEDURE

SADI-S with a 300cm common channel

Also known as: Single- Anastomosis Duodenal Switch
SADI-S

Classic minigastric bypass

Also known as: Single anastomosis or Omega loop gastric bypass
Minigastric bypass
