Improvement in Physical Performance and Obesity Surgery in Patients Older Than 60 Years

The bariatric procedure is a gastric banding under general anesthesia with all the centres using the same surgical procedure (harmonized by group meetings). The laparoscopic surgical procedure has been described. The ERAS protocol will be applied in each centre. The inflation of the band will follow the procedures described by 0'Brien. The patients will attend a group education session before surgery, during which the eating behaviour with a band will be explained and practiced. Then after surgery, the routine procedure is applied.
