Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
