Endoscopic Sleeve Gastroplasty

Gastric restriction is one of the fundamental principles of gastric bypass and gastric banding. Nowadays, practitioners have the possibility to reduce stomach size by merging tissues through an endoscopic endoluminal suture approach without any incision. This could reduce the complications associated with current surgical techniques while obtaining the target gastric restriction, weight loss, comorbidities and quality of life improvement.

The primary objective of this study is to assess weight loss after endoscopic sleeve gastroplasty in patients with morbid obesity according to the technique described in the literature: reduction of the gastric pouch into a sleeve structure by modification of the stomach greater curvature thanks to a plication.
