Abstract
A foreign body in the intestinal tract, such as a fish hone, rarely causes perforation of the intestinal tract, abscess or inflammatory granuloma, since it usually passes through without difficulty. We report 2 cases with retroperitoneal abscesses caused by fish bone penetration. Both were treated by retroperitoneal drainage. A 73-year-old man and an 83-year-old man with retroperitoneal abscesses including a fish bone were admitted to our hospital. One had the abscess in the retroperitoneal space of the right kidney and the other in the dorsal space of the descending colon. Retroperitoneal space drainage was performed without celiotomy. We found fish bones, removed them and placed drains in the space. Preoperative correct diagnosis and removal of fish bones are important in this disease, and the most appropricte operation should be selected for each case.
