A Case of Appendicitis due to Fish Bone Abscess Formation in the Abdominal Wall

Abstract

One year earlier, a 58-year-old man noticed swelling in the right lower abdomen. Abdominal computed tomography (CT) showed an abdominal wall abscess continuous with the appendix, and linear calcification was observed inside. At that time, the symptoms improved with conservative treatment. However, due to repeated recurrence and disappearance, surgery was performed. The root of the appendix was ligated and dissected with a laparoscope, and the appendix was removed together with the surrounding abdominal wall. The skin just above the abscess was incised and drained. Since a fish bone was found in the appendix, it was determined that the source of infection had been removed, and the operation was terminated. The patient's postoperative course was uneventful, and the patient was discharged from the hospital on the 6th day. A case of appendicitis due to fish bone abscess formation in the abdominal wall, which underwent both laparoscopic and local approaches, is reported, along with a review of the relevant literature.
