She was diagnosed with perforated appendicitis and abscess formation on CT. She was treated conservatively with antibiotics and discharged. On control CT 3\u2009months later, the appendix had healed, but signs of thickening of the terminal ileum were noticed and colonoscopy was performed, which was uneventful and showed no signs of inflammation. Twelve hours later, she developed pain in the right lower quadrant, followed by fever, and visited the ED. Physical examination and blood work showed signs consistent with acute appendicitis, and appendectomy was performed laparoscopically 6\u2009hours later. The patient recovered remarkably shortly afterwards. Whether colonoscopy resulted in de novo appendicitis or exacerbated an already existing inflammation remains unknown. However, endoscopists should be aware of this rare, yet serious complication and consider it in the workup of post-colonoscopy abdominal pain.<\/jats:p>","DOI":"10.1136\/bcr-2021-242523","type":"journal-article","created":{"date-parts":[[2021,7,26]],"date-time":"2021-07-26T12:41:03Z","timestamp":1627303263000},"page":"e242523","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":4,"title":["Appendicitis:
