BackgroundThe rate of recurrent appendicitis is low following nonoperative management of complicated appendicitis. However, recent data suggest an increased rate of neoplasms in these cases.MethodsThe study was a retrospective review of patients with acute appendicitis at 2 university-affiliated community hospitals over a 12-year period. The primary outcome measure was the incidence of appendiceal neoplasm following interval appendectomy.ResultsSix thousand thirty-eight patients presented with acute appendicitis. Appendectomy was performed in 5,851 (97%) patients at the index admission. Of the 188 patients treated with initial nonoperative management, 89 (47%) underwent interval appendectomy. Appendiceal neoplasms were identified in 11 of the 89 (12%) patients. These included mucinous neoplasms (n = 6), carcinoid tumors (n = 4), and adenocarcinoma (n = 1). The rate of neoplasm in patients over age 40 was 16%.ConclusionsThere is a significant rate of neoplasms identified in patient over age 40 undergoing interval appendectomy. This should be considered following nonoperative management of complicated appendicitis.
