ObjectivesThe rate of negative appendectomy in children is 7%. The value of imaging depends on the institution. In addition, imaging errors can lead to an appendectomy in children who do not have appendicitis. It is the hypothesis that children with short onset of symptoms who undergo negative appendectomy often have erroneous imaging findings.MethodsA retrospective study of patients' records over a 30-month period was carried out. A search by histologic diagnosis in the department of pathology was used to identify the cases of all patients who did not have a diseased appendix with the preoperative diagnosis of appendicitis. In addition, the imaging report was reviewed for the radiologic diagnosis of each patient, and the operative note was reviewed to document the clinical indication for surgery.ResultsA total of 1377 patients who underwent appendectomy with the preoperative diagnosis of appendicitis were reviewed. Sixty-eight of these children did not have an abnormal pathologic diagnosis; hence, there was a negative appendectomy rate of 4.8%. All 68 had imaging before surgery consistent with appendicitis. Thirty-six of these patients had symptoms less than 3 days. In 30 (84%) of these 36 patients, the note identifies imaging as the indication for surgery.ConclusionsChildren who had an appendectomy and found to have a normal appendix shared 2 characteristics. (1) Their symptoms were less than 3 days, and (2) the imaging was considered the indication by the surgical team. In the situation of an unclear diagnosis and a short onset of symptoms, observation or further evaluation should be considered.Copyright © 2020 Wolters Kluwer Health, Inc. All rights reserved.
