Arms and Interventions

Arm Intervention/treatment
Experimental: Inertervention group_Clips to avoid internal herniation
LRYGB with closure of the defects with simple hernia stapler clips. Aim of this study is to evaluate the benefits and disadvantages of closing the mesenteric defects during gastric bypass in order to avoid internal herniation.
Procedure: Closing the mesenteric defects with clips during opration
The laparoscopic Roux-en-Y gastric bypass surgery will be performed as usual. The patient will receive the closing of the mesenteric defects (the Petersen´s space and the entero-enterostomy site).The closing will happen at the end of the operation, using clips (herniestapler).
Other Name: Clips, Herniestapler, Internal hernia, Gastric bypass
No Intervention: Control group
conventional LRYGB without closure of the mesenteric defects

Outcome Measures

Primary Outcome Measures :
  1. To avoid the risk of Internal Hernias in patient with a Gastric bypass [ Time Frame: 5 year ]

Secondary Outcome Measures :
