Natural history of incidental appendectomy in patients with Crohn's disease who required subsequent bowel resection.

Overview

The records of 20 patients with Crohn's disease who underwent incidental appendectomy and later required bowel resection were reviewed and the following conclusions ascertained. If the patient had had abdominal pain for less than 1 week, appendectomy is followed by minimal problems. If the patient has had abdominal pain for longer than 1 week, incidental appendectomy is followed by an 83 percent incidence of fistula or sinus tract, arising not from the appendiceal stump but from the terminal ileum. The natural history of patients with resection after appendectomy includes more medication and a higher symptom recurrence rate and perhaps operative recurrence rate than their counterparts who have not undergone incidental appendectomy.
