title: [Radioisotope and biochemical methods in the study of exocrine function of the pancreas and small intestine at early periods after gastrectomy for cancer].
abstract: 77 patients were examined during a period from 1 to 30 days following gastrectomy for cancer. Depression of the exocrine function of the pancreas was observed. The concentration of amylase, lipase and trypsin was found to be reduced during the first 5 days after the operation. Following 19-30 days the amylase concentration is restored, the lipolytic activity is enhanced, whereas the tryptic one remained considerably impaired. The small intestine functioning is markedly disturbed, the processes of hydrolysis and fat absorption suffering most of all; the protein absorption is changed but to a less extent.
