Appendectomy is the standard treatment for acute appendicitis in adults and children. However, more and more studies demonstrate that a conservative treatment with antibiotics and radiological drainage, if required, is effective and may be of importance in complicated cases and in older frail patients .
In the absence of randomized controlled trials, there is no consensus on whether an appendectomy at distance from the acute phase (interval appendectomy) is necessary for conservatively treated patients. A large observational study has shown that about 10% of these patients will require an appendectomy  over a period of several years. However, a histopathological study of appendices removed during interval appendectomy after conservative management of pediatric patients with acute appendicitis with an inflammatory mass or abscess concluded that more than half of the patients had strong histopathological changes in the appendix, thereby suggesting a high possibility of recurrence .
This is the case of a 58-year-old female patient presenting with a perforated appendix with an appendiceal abscess, treated by antibiotherapy and radiological drainage. She has a past history of uterine cancer treated by radiochemotherapy and total hysterectomy, complicated by bilateral ureteral stenoses after radiotherapy, treated by long-term pig-tail urinary catheters, as well as a postoperative abdominal hernia treated by means of an abdominal underlay mesh. Even though the initial non-surgical treatment of her complicated acute appendicitis was successful, an interval appendectomy was indicated because of persistent abdominal pain in the right lower quadrant (RLQ). The operation was performed laparoscopically with a simple postoperative course.
