Applying basic principles of surgery may pave the way for more effective endoscopic bariatric techniques.

 In the last decade, gastroenterologists have been attempting to use endoscopy to reproduce the great success of traditional surgical suture techniques. Despite recent advances, we still lack a reliable method that results in a permanent suture with minimal incidence of suture failure.
