Introduction: Roux-en-Y gastric bypass is an effective treatment for severe obesity. However, many patients regain weight over time. In this setting, dilation of the gastrojejunal anastamosis and distention of the gastric pouch leading to increased food intake are two possible mechanisms for weight gain. Preliminary studies of endoscopic techniques have shown success with endoscopic anastamotic reduction.

Methods: In this video, we describe a novel procedure called Revision Obesity Surgery, Endoscopic (ROSE) using an endoscopic suturing and tissue plicator device called the EndoSurgical Operating System (EOS). With this system, both anastamotic and pouch reductions can be performed.

Results: In this video, we provide a detailed overview of EOS. We demonstrate its safety and technical feasibility in achieving both anastamotic and pouch reduction in a series of patients who had regained weight following gastric bypass surgery.

Conclusions: The ROSE procedure using EOS is a feasible and safe peroral endoscopic treatment for anastamotic and pouch reduction in patients who have gained weight following gastric bypass surgery. The technical feasibility demonstrated in this early work is encouraging and further studies to assess long-term efficacy are underway.
