Non-Operative Management of Uncomplicated Appendicitis in Children: Can Patients Be Discharged From the Emergency Department?

Introduction: Non-operative management of uncomplicated appendicitis in children is a safe alternative to laparoscopic appendectomy. The purpose of this study is to determine the feasibility of nonoperative outpatient management of uncomplicated appendicitis in pediatric patients.

Methods: A standardized pathway for non-operative outpatient management of uncomplicated appendicitis in children (NOMA-C) was implemented in a university pediatric surgery practice starting October 2021. Those who met criteria would be considered for discharge from the emergency department (ED) with oral antibiotics and close followup over the following year. A quality improvement project started concurrently to monitor patients for recurrent symptoms of appendicitis.

Results: A total of 121 patients were diagnosed with acute appendicitis during the study period (October 2021 to April 2023). Forty-five children (38%) met criteria for the NOMA-C protocol, and 11 patients/families chose appendectomy. Of the 34 patients who pursued nonoperative management, 14 patients were admitted to the hospital and 20 patients were discharged from the ED. Total time in the ED/hospital was significantly shorter for patients discharged from the ED (7 hours versus 23 hours; p<0.001). At one year follow up only 4 (12%) had undergone appendectomy. There were no adverse events for patients who underwent nonoperative management.

Conclusion: A protocol offering non-operative management of appendicitis with an option for outpatient management was feasible and safe. Outpatient management was associated with shorter ED/hospital stays than those admitted. Future studies should evaluate whether this protocol can be adopted by EDs without pediatric surgery services to avoid the need for transfer.
