Perianal abscess due to a long fish bone: a case report

Taro Ikeda et al. J Surg Case Rep. .

Abstract

Few articles have reported cases of perianal abscess due to ingested foreign bodies. Herein, we report a case of perianal abscess due to a long fish bone. A 72-year-old man who was toothless and wore a denture had a chief complaint of anal pain. His left-side buttock had swelling and redness. Computed tomography revealed a perianal abscess on his left-side buttock and high-intensity linear structure in the abscess cavity. We made a diagnosis of perianal abscess due to a fish bone and performed an emergency operation. We opened the abscess cavity and removed the 5 cm fish bone from the cavity. After drainage of the abscess cavity and antibiotic administration, he was discharged from our hospital on day 8. A long fish bone could cause perianal abscesses. Rapid diagnosis and ensuring fish bone removal are important to prevent sepsis.
