title: Laparoscopic resection of omental actinomycosis forming fistula with transverse colon and jejunum:  a case report and review of literature.
abstract: Omental actinomycosis without any predisposing factors is rare, and there are few reports on it invading the contiguous bowels to form fistulae. We describe the case of a 55-year-old male patient with omental actinomycosis that presented as an inflammatory tumor that formed fistulae with the transverse colon and upper jejunum. On admission, he had complaints of a palpable, tender mass on the left mid-abdomen without gastrointestinal symptoms. After 7 days of conservative treatments (NPO and intravenous antibiotics), the size of the mass was decreased and tenderness was more improved. Laparoscopic resected omental mass revealed fistulae to the colon and jejunum. There was no evidence of Crohn disease. After 1-week use of antibiotics owing to the concern about actinomycosis, the mass was decreased and it was more amenable to dissect laparoscopically.
