Abstract

<p>An 84-year-old man presented with abdominal pain and underwent laparoscopic appendectomy with a diagnosis of acute appendicitis. Intraoperative findings showed abscess formation and perforation of the appendiceal wall. Histopathological findings revealed appendiceal cancer, tub2, PM1. Later, laparoscopic ileocecal resection (D3) was performed for the purpose of additional resection. The final diagnosis was pT3, pN0, pM0, pStageIIa. One year after the operation, a 23 mm-sized mass was found by CT scan, and FDG-PET/CT showed abnormal accumulation. Local recurrence of appendiceal cancer could not be ruled out, so mesenteric tumor resection and partial ileocolonic resection were performed. Histopathological findings revealed a foreign body reaction to silk thread and abscess formation, and the diagnosis was suture abscess. The silk thread used for ligation was considered to be the cause of the suture abscess. It should be noted that suture abscesses are often difficult to distinguish from local recurrence.</p>
