The management of appendiceal mass in children: is interval appendectomy necessary?

In this study we aimed to show that performing interval appendectomy is unnecessary in the management of appendiceal mass in children. Between 1990 and 1996, 866 patients were treated for appendicitis. Abdominal ultrasonography (USG) was performed in patients who were admitted with abdominal pain, vomiting, and fever accompanying a mass in the right lower quadrant. Seventeen patients (12 boys and 5 girls, with a mean age of 9.5 years) with a mass in the appendiceal lodge and no abscess formation were treated conservatively. Appendectomy was performed on any patients with perforated or unperforated appendicitis who had an appendiceal abscess with a mass in the right iliac fossa. Three-agent antibiotic therapy was administered for at least 1 week. These patients were discharged after a mean hospital time of 9.7 days if regression of the mass was seen ultrasonographically. They were followed up for 1-60 months by physical examination and USG, and 11 of the 17 also underwent barium enema. USG demonstrated disappearance of the mass and barium enema showed a normal appendix in 10 of the 11 patients. No recurrent appendicitis was detected during follow-up for 1-7 years. This study shows that appendiceal masses that are perforated, but localized with no fluid content revealed by USG, can be treated conservatively even if they are detected late.
