NCT02779322

Brief Summary

This study try to identify differences in cost, length of operation and results between two different bariatric surgical techniques, the laparoscopic Roux-en-Y gastric bypass and the Single anastomosis laparoscopic gastric bypass. The study will be conducted in a Spanish public health system hospital. The patients of the trial will have the preoperative studies, hospital treatment during the admission, postoperative treatment and follow up as any other patient included in the hospital bariatric surgery program. No new methods are applied other than randomly choose the surgical technique. Patients will be randomized in a 1:1 ratio to each group.

Study Arms (2)

Minigastric bypass

ACTIVE COMPARATOR

Intervention(s): The patient will have done a Laparoscopic one anastomosis gastric bypass (minigastric bypass) at the time of the surgical procedure.

Procedure: Minigastric bypass

Gastric bypass

ACTIVE COMPARATOR

The patient will have a Laparoscopic Roux-en-Y gastric bypass at the time of the surgical procedure

Procedure: Gastric bypass

Interventions

The patient will be submitted to a minigastric bypass at the time of the operation

Also known as: Single or One anastomosis gastric bypass
Minigastric bypass

In this case a simplified conventional gastric bypass will be performed

Also known as: Laparoscopic gastric bypass
Gastric bypass
