Italian multicenter experience of Roux-en-Y gastric bypass on vertical banded gastroplasty: four-year results of effective and safe innovative procedure enabling traditional endoscopic and radiographic study of bypassed stomach and biliary tract

The results of our study have shown that RYGB-on-vertical banded gastroplasty is as effective as traditional RYGB, while allowing for traditional radiography of the bypassed stomach in every patient. Endoscopy of the distal stomach and, therefore, the biliary tract, was also possible. These are the fundamental aspects of the procedure.
