Study summary

To determine if non-operative management with antibiotics alone is a feasible treatment alternative for pediatric patients with uncomplicated acute appendicitis with an appendicolith identified on imaging.

Read the detailed description

This study is a prospective randomized clinical trial comparing non-operative management with antibiotics to urgent appendectomy in children (ages 7-17yrs) with acute appendicitis with the presence of an appendicolith. Enrolled participants were followed up to 1 year post-discharge to observe the rates of appendicitis recurrence as well as identify the number of patients with complicated appendicitis as determined by pathologic examination.

What researchers measure

Primary outcomes

  1. Number of Participants That Did Not Have an Appendectomy
