Detailed Description:

The aim of this study was to prospectively and randomly compare three different techniques of SLR during LSG: oversewing (group A), buttressed transection with a polyglycolide acid and trimethylene carbonate (group B) and staple-line roofing with a gelatin fibrin matrix (group C).
