Vertical banded gastroplasty (VBG): (A) – scheme based on [18], own modification; (B) – barium meal examination after Mason’s operation: small proximal gastric pouch (short arrow), gastric lumen narrowing at the location of band (arrowhead, band itself is not visible on X-Ray), and the gastric fundus clearly separated from pouch (thick arrow); (C) – X-Ray of other patient after barium meal highlights correct line of staples (between arrowheads, staples are not visible), separating pouch from the fundus.
