title: Long-term Result of Treatment of Prader-Willi Syndrome by Scopinaro's Bilio-pancreatic Diversion. Study of Three Cases and the Effect of Dextrofenfluramine on the Postoperative Evolution.
abstract: The Prader-Willi Syndrome shortens the life of patients due to the morbid obesity which it entails. The compulsive hyperphagia associated with it makes a dietetic treatment or a gastroplasty difficult. This study presents the case histories of three patients suffering from the Prader-Willi syndrome who were operated on by means of a Scopinaro's bilio-pancreatic diversion. Following a marked reduction the first year, the weight loss stabilized and then tended to diminish. The observation of three cases which continued for two and a half to six years did not reveal any considerable metabolic problems. The deficiency of iron, vitamins D and B12 as well as folic acid had to be made up by supplementation. These results are comparable with the most favorable ones in the literature. Even if the effect on the weight loss is not spectacular, the operation manages to hold off the development of the obesity, inexorable for those with the Prader-Willi syndrome, and prevents lethal complications, without having notable side effects. Lifting coercive dietary measures improves the quality of life.
