An 87–year–old man who developed severe abdominal pain was diagnosed as having an intestinal perforation with an intraabdominal abscess based on CT findings. Thus, the patient underwent an emergent laparoscopic operation requiring a partial intestinal resection. However, the patient postoperatively had a relapse of the same symptoms. A second CT showed another abscess near the anastomosis. Thus, conservative management was performed. The patient was discharged, but he was later re–admitted with an abscess in another location. Moreover, another abscess required the patient to be hospitalized a third time. CT and intestinal endoscopy indicated a diagnosis of intestinal diverticulitis caused by multiple intestinal diverticula. However, the persistent symptoms required the patient to undergo laparoscopic surgery. The resected specimen revealed that a needle–like foreign body was in fact a wooden toothpick. This case serves as an important reminder to consider foreign bodies in investigations of all possible causes of intraabdominal abscess with a repeated history of abscess.
