Condition gastroesophageal reflux disease (gerd)
Treatment medigus srs endoscopic stapling system
Phase phase 3
Sponsor Aviel Roy-Shapira, M.D.
Start date May 2008
End date May 2011
Trial size 72 participants
Trial identifier NCT00734747, DCLP09002


The study is designed to test the safety and efficacy of the Medigus SRS endoscopic stapling system for the treatment of GERD.

The system allows the operator to staple the stomach to the esophagus,in order to restore the gastroesophageal flap valve. The effect of the stapling is similar to a common operation for GERD (partial fundoplication) but is done through the mouth, and incision into the abdomen is not needed.

The hypothesis of the study is that the treatment will be effective in improving GERD related quality of life by 50% or more in the majority of the subjects, and that the procedure will be as safe as surgery.

Study Design

Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
Endoluminal fundoplication for the treatment of GERD
medigus srs endoscopic stapling system endoluminal treatment of GERD
The system is designed to staple the stomach to the esophagus in 2 or 3 locations using a quintuplet of standard B shaped, 4.8 mm titanium staples in each location.
