Abstract
A 75-year-old man arrived at our hospital by ambulance due to abdominal pain and fever and was admitted under a diagnosis of iliocecal abscess due to acute appendicitis. The abscess increased despite conservative treatment ; therefore, we performed percutaneous drainage on hospital day 13 and he was discharged on day 28.
Subsequently, colonoscopy revealed a tumor protruding from the appendix and biopsy revealed that it was a tubular adenoma requiring laparoscopic ileocecal resection. The resected pedunculated tumor of the appendix measured 15 × 10 mm and the histologically confirmed diagnosis was tubular adenoma. The postoperative course was complicated by an umbilical wound infection and retroperitoneal emphysema, but these were cured by conservative treatment. He was discharged on postoperative day 30. A preoperative diagnosis of rare benign adenoma of the appendix is a good indication for laparoscopic surgery.
