[Non-specific fermentemia as a possible cause of postoperative disorders of motor function of the small intestine].

The authors studied duodenal myoelectric activity and the activity of trypsin, alpha 1-antitrypsin, alpha 2-macroglobulin, alpha-amylase, and kallikrein after 15-minute occlusion of the hepatic portal vein. The correlation was found between the activity of alpha 1-antitrypsin and the phases of the myoelectrical complex. It is concluded that the discharge of pancreatic proteases during an operative trauma may underlie the pathogenesis of postoperative inhibition of intestinal peristalsis.
