[Ulcero-necrotic enterocolitis complicated by peritonitis].

Among 217 patients with acute peritonitis there were 12 patients with the peritonitis developed against the background of segmentary enteritis or colitis. The article describes this form of peritonitis characterized by great severity, rapid development and high death rate. On the detection of a necrotic segment of the small intestine, a one-step resection within the limits of healthy tissues is indicated. Two-steps operations are expedient for necrosis of the colon.
