ABDOMINAL FOREIGN BODY FISH BONE PENETRATED TO THE PREVIOUS WOUND OF APPENDECTOMY -A CASE REPORT-

Abstract

A 57-year-old man was seen at our hospital because of abdominal pain and low grade fever. There was a previous history of undergoing an appendectomy. When he was seen, a tumor about 5cm in diameter was palpable just beneath the previous appendectomy scar. Careful scrutiny was started to find relationships with the previous operation. Abdominal computed tomography revealed an abdominal wall abscess and a linear calcification about 5cm in length surrounding the tumor. Although he denied accidental ingestion of any fish bone, granuloma derived from fish bone was highly suspected in its shape and an emergency operation was performed. The tumor was firmly adherent to the greater omentum but free from the intestine. There was no evident perforated site in the intestine. Then, a fish bone about 5cm in length was found inside of the tumor, which was chronic granuloma penetrating the abdominal wall to form the abscess.
