Abstract Background The optimal treatment of appendiceal phlegmon or abscess with an appendicolith is controversial. This study aimed to evaluate outcomes and prognosis of nonoperative management of appendiceal phlegmon or abscess with an appendicolith in children. Methods From 2007 to 2011, 105 children with appendiceal phlegmon or abscess who were treated nonoperatively without interval appendectomy were reviewed. Average follow-up of subjects was 2.4 years. Data were compared between subjects with and without an appendicolith or persistent presence and disappearance of an appendicolith. Results The success rate for nonoperative therapy for appendiceal phlegmon or abscess with appendicolith was 95.9 %. The risk of recurrent appendicitis in appendiceal phlegmon or abscess with appendicolith (19.1 %) was higher than that without appendicolith (8.9 %, P=0.132). The rate of appendicolith disappearance during follow-up was 80.9 %. The persistent presence of an appendicolith was associated with a significantly higher recurrence rate (66.7 %) compared with appendicolith disappearance (7.9 %, P
