Analysis of Follow-Up Results after Successful Conservative Treatment of Pediatric Appendiceal Abscess- A Single Institutional Retrospective Study

Purpose: The follow-up results of successful conservative treatment of appendiceal abscess in children were analyzed to further explore the value of interval appendectomy (IA).
Method: Follow-up was conducted for children with appendiceal abscess who were successfully treated conservatively for the first time in our department from January 2015 to December 2019. The recorded data included: imaging data (abdominal ultrasound or abdominal CT), frequency of recurrence, inflammatory indicators, intraoperative status, postoperative pathology, etc.
Results: A total of 48 children (male/female = 21/27), with an average age of 10.82.6 years, were included in this study. They were followed up to December 31, 2019, during which four patients underwent interval appendectomy, and the pathology suggested chronic appendicitis or simple appendicitis. There were 9 cases with recurrence (18.7%), among which 7 cases occurred within 3 months after the first conservative treatment,4 cases underwent surgery,5 cases were treated with conservative treatment again, 1 case relapsed and underwent surgical treatment, and the remaining children had not relapsed during follow-up up to date.
Conclusion: The recurrence rate of children with successful conservative treatment of appendiceal abscess is low and there is no significant correlation between appendiceal beecar and recurrence. Planned interval appendectomy is not necessary. If the operation is selected, the interval of at least 10 weeks is recommended.
