[Pathogenesis of enteral insufficiency in patients with postoperative peritonitis].

Enteral insufficiency is considered to trigger the syndrome of endogenous intoxication and, further, multiple organ failure. Enteral insufficiency often accompanies postoperative septic complications, such as peritonitis. Morphologic changes of the intestinal wall by septic peritonitis consisted of edema, fibrinous degradation of muscular layer and dystrophy of local nervous pathways. Microbiologic analysis of intestinal and gastric contents, peritoneal fluid and blood samples demonstrated a broad spectrum of pathogenic flora. Besides, enterotoxin allocated from blood and intestinal contents coincided in all cases. Adequate algorithm of detoxication, including extracorporal methods, had been worked out.
