A 16-year-old girl presents with a 24-hour history of pain in the right iliac fossa. A pregnancy test is negative and bloods show a raised white cell count. Her parents tell you she has had a ‘cold’ for the past week. She also began to suffer from headaches two days before the pain.
The girl is taken to theatre for a laparoscopic appendicectomy. However, during the operation, the appendix is found to be completely normal.
How should the surgical team proceed?
