Appendiceal colic: A rare complication of colonoscopy

We report a case of appendiceal colic presenting as chronic right lower quadrant abdominal pain, without leukocytosis or other inflammatory signs, following an uneventful colonoscopic exam without biopsy or polypectomy. The resected appendix appeared grossly abnormal and was engorged with fecal material. The patient was immediately relieved of pain and remains so four years postoperatively. We conclude that insufflation of the cecum caused inspissation of fecal material into the lumen of the appendix. The ensuing incomplete or partial obstruction of the appendiceal lumen resulted in development of appendiceal colic without any signs or symptoms of inflammation.
