Abdominal actinomycosis: A complication of colonic perforation.
Actinomycosis is a chronic, suppurative, mycotic infection, which tends to form abscesses and fistulas. The organism is a saprophyte of the human mouth. When a break in the normal contiguity of the gastrointestinal tract occurs, the organism may gain access to the surrounding tissues and become almost impossible to eradicate without surgical extirpation and administration of a long course of antibiotics. The diagnosis of actinomycosis should be considered for any patient in whom persistent or unusual enterocutaneous fistulas develop, when there is a recent history of perforated viscus or surgical intervention involving the gastrointestinal tract, such as appendectomy. The diagnosis is confirmed by the presence of "sulfur granules" in the fistulous tracts.
