Would you resort to surgery as a method of weight loss? Most people would say no, but there are some people where surgery is the only option left open to them. The lap band was recommended to a family member that cannot exercise because of lack of mobility. That person uses food as a comfort. Depression of his condition triggers him to eat more which in turn depresses him. It is a vicious cycle.
I would not recommend you go out and find a lap band doctor on your own. You need to go through your doctor for all the information and discuss the surgery with him/her. After all, lap band surgery is MAJOR surgery and not to be entered into lightly.
