Core Tip

Core Tip: Multifocal intraabdominal foreign body granulomas (IFBGs) caused by gastrointestinal perforation are clinically rare and mimic peritoneal dissemination. An 86-year-old woman underwent an operation to treat an incarcerated femoral hernia; however, the incarcerated ileum was perforated due to hemorrhage necrosis, resulting in incarcerated ileum resection. After 4 mo, a second laparoscopic operation was conducted for an umbilical incisional hernia; however, small, white nodules were identified throughout the entire abdominal cavity, mimicking peritoneal dissemination. Using intraoperative cytology and frozen sections, the nodules were diagnosed as IFBGs. IFBGs sometimes mimic peritoneal dissemination, and intraoperative pathological examinations are effective for rapid diagnosis.
