EP.FRI.229 The Role of Ultrasound in the Diagnosis of Paediatric Appendicitis

Abstract

Abstract Background Acute appendicitis remains the most common acute surgical presentation among children and adults. Ultrasonography is a commonly used investigation for patients with right iliac fossa pain were the diagnosis is unclear, however in a district general hospital (DGH), appropriate radiologists are not often readily available. The aim of this study was to determine the value of ultrasonography in the diagnosis of appendicitis in children. Methods A retrospective review was carried out of all paediatric patients (aged 5-16), who underwent an appendicectomy in a single acute surgical unit, over a 6 month period. An institutional database and up to date electronic care records were used to record preoperative ultrasound results, intraoperative findings and histopathology results. Results A total of 59 patients were admitted with possible appendicitis within the audit window, 31 of which underwent an appendicectomy, 58% performed laparoscopically. 38.7% underwent pre- operative ultrasound, 33.3% of which identified an acutely inflamed appendix. The remaining patients who did not proceed to theatre were successfully discharged with no re-attendance following a period of observation. Following histopathological confirmation, ultrasonography was found to have a sensitivity and specificity of 100%. Negative appendicectomy rate returned at 6.7%. Conclusion Ultrasonography is a low cost, highly sensitive diagnostic tool in appendicitis, where provisions are in place to do so. Visualising the appendix on ultrasound can reduce negative pathology rates. This is a small study within a DGH and access to ultrasound is limited. Better utilisation or the development of a protected ultrasound slot should be sought.
