Abstract

Most foreign bodies in the gastrointestinal tract are digested or excreted. However, in rare cases, they can cause gastrointestinal injury and acute abdomen. In Japan, fish bones are the most frequent type of foreign body causing acute abdomen. We treated eight cases of acute abdomen caused by fish bones and report herein on them with a discussion of the literature. The patients were aged from 55 to 86 years old (four men and four women, mean age: 74.1 years). For all the patients, the chief complaint was abdominal pain. The site of perforation or penetration was the small intestine in six patients and the colon in two patients. Seven patients were diagnosed as having acute abdomen caused by a fish bone prior to treatment. Two patients improved with conservative management. Two of the six patients who underwent surgery were able to undergo laparoscopic surgery. Acute abdomen caused by a fish bone can often be diagnosed with computed tomography in addition to the patient's medical history such as their dietary intake. While many patients are indicated for surgery, some patients improve with conservative management. Therefore, imaging and abdominal findings should be adequately taken into account when determining the management strategy. Laparoscopic surgery can be less invasive in some cases.
