Evaluation of the Fundoplicature of the Excluded Stomach Post Omega Bypass

The FEE& RGOIC trial is a single-center, ambispective, interventional, non-randomized pilot study to evaluate the efficacy of Fundoplicature with stomach excluded objectively and comprehensively in the treatment of disabling gastroesophageal reflux requiring gastric bypass after anastomosis.

The strategy under study is objective reflux suppression after fundoplication with the stomach excluded in the following specific context: treatment of disabling gastroesophageal reflux requiring post-bypass surgery in Omega.

The eligible study population will be any adult patient at the investigating center who has undergone one-anastomosis gastric bypass surgery followed by fundoplication of the excluded stomach as part of treatment for disabling post-bypass gastro-oesophageal reflux, resistant to medical treatment and requiring surgery.
