[Pathogenesis of abdominal actinomycosis].

According to the author's findings in 80 of 125 patients under observation the development of abdominal actinomycosis was related with inflammation in the appendicular process, in 65 patients the former starting after appendectomy. In examination of 100 patients with diagnosis of acute appendicitis actinomycosis of the ileocecal region was diagnosed in 5 patients. Actinomycosis was spreading from the ileocecal region by contact in retroperitoneal cellular tissue in 23 cases, in the left iliac region--in 12, in the lesser pelvis--in 8.
