[Current world experience in the surgical treatment of gross obesity].
Since 1954 the aim of surgical treatment of severe obesity has been to perfect a specific treatment capable of obtaining a massive, long-lasting and well tolerated loss of weight in severely obese subjects in which different and repeated attempts using conservative medicine have proved inefficacious or non-resolutive. During the course of almost 40 years, bariatric surgery has gradually evolved in the search for the "ideal" surgical treatment: for this purpose, operative methodologies and techniques have been proposed and experimented using differing physiopathological concepts and means of application. After a brief analysis of the history of bariatric surgery, there is a short summary of the most internationally widespread surgical methods and the most recent techniques now used for the surgical treatment of severe obesity based on the Authors' ten year experience of 321 intestinal bypasses (jejuno-ileal and biliointestinal), 110 horizontal gastroplasties and 23 vertical gastroplasties with a silastic ring. Intestinal bypass almost always allows sufficient weight loss to be achieved (85% of operated patients lose 80% of excess body weight) and the various postoperative problems of differing degrees of severity can be prevented by adequate replacement therapy and regular outpatient monitoring. Gastroplasties lead to a slightly smaller loss of weight (73% of excess body weight) within a shorter period of time, with fewer postoperative problems, but at the expense of a drastic and continual reduction in food intake. All patients operated require intense and long-term postoperative follow-up carried out by experts in order to achieve the desired results.
