Purpose
Silastic rings have been used around the gastric pouch in order to promote better weight loss after Roux-and-Y gastric bypass surgery ( RYGBP). However the investigators have shown that some patients developed gastroesophageal reflux disease after RYGBP in a previous study. The investigators hypothesized that the use of a silastic ring may play a role in promoting GERD after this operation.

Primary Outcome Measures:
- Occurence of gastroesophageal reflux disease [ Time Frame: march 2010 to march 2014 ] [ Designated as safety issue: No ]Patients are intra-operatively selected to receive or not a silastic ring following a open gastric bypass. These patients will be evaluated for GERD with upper endoscopy, 24h ph-monitoring, validated questionnaires which will be performed at 6 month, 1 and 2 years.
Secondary Outcome Measures:
- The role of the ring in open GBP in terms of weight loss [ Time Frame: march 2010 to march 2014 ] [ Designated as safety issue: No ]It will be possible to evaluate the weight loss among the groups: 1) with ring and, 2) without a ring
- The impact of the ring on food tolerance [ Time Frame: March 2010 to March 2014 ] [ Designated as safety issue: No ]To identify food intolerance among the groups: 1) with the ring, and 2) without the ring.

Sham Comparator: no ring
Patients at this group will have RING REMOVED AT THE END OF SURGERY.
|
Procedure: Sham Comparator: no ring
Open roux-en-Y gastric bypass not banded
|
|
Active Comparator: RYGBP-Ring
Open Roux-en-Y gastric bypass with a silastic ring which is performed with linear cut stapler 100 mm and a biliopancreatic limb of 60 cm long and a alimentary limb of 100 cm long. All patients will have a 6.5 cm silastic ring located at the middle of the pouch above of the gastroenteroanastomosis.

Procedure: RYGBP-RING
Vertical Roux-en-Y banded gastric bypass
|
Detailed Description:
This is a randomized controlled double blind trial designed to identify if the use of the ring induces food intolerance and vomiting which may lead a esophageal mucosal erosions and/or GERD symptoms.
