A case of retroperitoneal abscess caused by a fish bone

Abstract

Perforation of the digestive tract such as a fish bone caused by a foreign body is rare since the foreign body usually passes on its own. ; when it occurs, it can have very serious consequences. Most of the reported cases recovered with conservative therapy ; some cases required an enterectomy. We report a case of a retroperitoneal abscess caused by a fish bone that was found when the abscess was drained. An 83-year-old man was admitted to our hospital due to left lower abdominal pain. A retroperitoneal abscess caused by a fish bone was found. At surgery, the retroperitoneal space was accessed via a pararectus incision. The abscess was treated via drainage, without a need for bowel resection. A proper preoperative assessment allows a proper surgjcal approach to be chosen.
