[Influence of jejunoileostomy on the lipid fractions in morbidly obese patients (author's transl)].

In 35 morbidly obese patients, operated by Payne-De Wind's jejunoileostomy, the serum concentration of the lipid fractions was examined before and after operation. Before the operation an increase of total cholesterol and beta-lipoproteins was noted in 1/3 of the patients. Six months after the jejunoileostomy a considerable decrease of total cholesterol, beta-lipoproteins, total lipids and free fatty acids has been observed.
