[Measurement of granulocyte phagocytosis in vitro in the determination of non-specific cellular resistance in peritonitis].

First measurements of phagocytosis of neutrophilic leukocytes were made in 15 patients with peritonitis. All sorts of peritonitis were present. The measured values always show the summary of all present pathophysiologic and therapeutic influences on the phagocytic activity. It will be possible to estimate the patients resistance and the severity and prognosis of the illness. The higher risk of postoperative complications can be resulted by a reduced phagocytosis.
