proximal-vs-distal

does anyone know, what determining factors the Dr. uses to decide if you get the proximal or the distal procedure.

Hi Keith! My surgeon (Dr. Oh) told me to pick between the proximal, medial, and distal. He told me it was up to me to decide and let him know at my last visit before surgery. I chose the distal because I want to have a tool that will help me lose the most weight and to help keep it off. Julia
