[Surgical treatment of exogenous morbid obesity: results of Mason's vertical gastroplasty].

Among the various surgical methods of treating exogenous morbid obesity, Mason's vertical gastroplasty has gradually become the method of choice throughout the world. The method is relatively simple and the operating time short, so that if offers the great advantage of maintaining normal digestive activity free of metabolic disturbances. Between December 1981 and December 1988 we treated 160 patients in this way, the mortality in the series being nil. The results obtained are encouraging, since among 75 patients followed up for at least 2 year, 50 (66%) had a weight index between 20 and 25, 15 (20%) a weight index between 25 and 30, while 10 patients (14%) failed to respond to the treatment.
