[Fat and nitrogen balances after jejunoileal bypass for obesity (author's transl)].

Seventy-five patients after jejunoileal bypass for morbid obesity were investigated. The body weight, fat and nitrogen balances were followed. In the second year after operation the stabilization of body weight was observed. The fecal fat excretion was average one third of the ingested amount of fat and the fecal nitrogen loss was twice or three-times higher than normal value. In the first year after operation in many patients the positive nitrogen balance was stated on the ward, caused first of all by decrease of the nitrogen excretion in the urine. Authors conclude that the decrease of body weight is caused on the hand by decrease of oral intake and resorption of nutrients in the shortened small intestine and on the other hand by inadequate physical load after operation.

[Hemodynamics of the liver. II. Hemodynamics of the dog liver after resection of 70% of the liver and ligation of the left branch of the portal vein].

Blood supply to the liver was determined by help of the direct method after 70 per cent hepatic resection and after ligation of the left branch of portal vein in dogs. The total blood supply remains unchanged after both surgical procedures, while the circulation in the remaining lobes, resp. in those patent for portal blood stream, considerably increases. After the resection portal hypertension develops. This elevated portal pressure was not observed after ligation of the left portal branch.
