OBJECTIVE: This study was undertaken to validate the outcome of interventional drainage and IV antibiotics for the treatment of appendiceal abscesses in children. MATERIALS AND METHODS: Between March 1991 and March 1995, 46 children with one or more intraabdominal appendiceal abscesses were seen at a tertiary care referral center. The children received IV antibiotics and underwent interventional drainage of their collections. All procedures were performed in the radiology intervention suite using IV sedation and, in one patient, a general anesthetic. All patients were followed up for at least 1 year. RESULTS: The 46 patients underwent 64 procedures. These included the insertion of 34 percutaneous drainage catheters, the insertion of 25 transrectal drainage catheters, and five needle aspirations. Four patients did not respond to their initial treatment and required surgery. One patient developed a colonic fistula that resolved spontaneously. CONCLUSION: Successful treatment of 42 patients (91%) justifies image-guided drainage and IV antibiotics as appropriate management for appendiceal abscesses in children.
