History and pathophysiological analysis of the different surgical techniques in the bariatric surgery

Abstract

Bariatric surgery for the treatment of morbid obesity or overweight refractory to medical therapy was born at the beginning of second half of the twentyth century, and its first steps were uncertain and with a not jet well definite purpose. In fact the main result to be pursued seemed to be simply the reduction of body weight, and any change of anatomy of the digestive tract able to reduce the absorbtion of nutrients was judged adequate. But very early the adverse consequences of malabsorbtion so obtained became evident, and other operations possibly free from those complications were devised and clinically tested. So aside the by-pass operations many other surgical procedures found their room, all of them aiming to fight the ever more diffuse obesity of the people.

This historical review of the various surgical procedures attempted in these last sixty years for morbid obesity is very interesting for a better understanding of the problem and to have a solid basis for future rational choices
