Abstract
A 60-year-old man presented with gradually increasing abdominal pain for 10 days. Abdominal computed tomography (CT) showed an omental abscess and chronic inflammatory lesions due to a fish bone penetration. Laparoscopic partial omentectomy was performed and histological examination of the resected specimen revealed omental actinomycosis. The patient received 1 month of antibiotic therapy with oral penicillin G and achieved complete clinical recovery 19 months after the operation.
The perforation and penetration of the digestive tract due to an ingested fish bone can cause acute or chronic inflammation. We experienced the latter provoked by actinomycosis, inducing chronic inflammation forming an abscess or a fistula. We revealed from literature search that the type of pathogenic bacterium may make the difference between acute or chronic inflammation. Moreover, we reported the appropriate administration period of antibiotics and the efficacy of laparoscopic surgery.
