Early bariatric surgery revolved around inducing malab-sorption (Roux-en-Y gastric bypass surgery, biliopancre-atic diversion, duodenal switch) or promoting the feeling of satiety (Wilkinson's Marlex mesh, Bashour polypropylene clip). Early satiety procedures were nonadjustable and performed through a midline laparotomy.In its current format, bariatric surgery involves the laparoscopic insertion of an adjustable silicone band around the proximal stomach. The exact mechanism by which the laparoscopic adjustable gastric band (LAGB) induces weight loss is unknown, but it is hypothesised that it is by inducing satiety. Adjustments can be made through a saline-filled subcutaneous port, usually positioned in the epigastrium. Since its inception in 1994,1 this type of surgery has grown in popularity, and according to Medicare Australia statistics, in 2009, over 13 000 of these procedures were performed in Australia.
