645 An EGS-Led Service for Acute Appendicitis Enhances Surgical Training Whilst Improving Outcomes for Patients: Results of A 6-Month Audit
Abstract Introduction Appendicitis is common &treatment by appendectomy is usually undertaken. Variations in diagnostics &imaging are accompanied by high negative appendectomy rates (NAR) of around 20%. This study evaluated the outcomes of appendectomy in a dedicated Surgical Emergency Unit. Method All patients undergoing emergency appendectomy between 1stSept 2019&29thFeb 2020 were identified. Demographics, clinical findings, pre-operative investigations, intra-operative findings &post-operative outcomes were recorded. Results There were 192 patients (102 [53.1%] female;90 [46.9%] male). Median age was 36 years(range 8-80)with 25 below 14.Some 58.3% underwent imaging (ultrasound 33.5%; CT 32.5%). Laparoscopic appendectomy (LA) was performed in 84.4% of cases with 11.4% open; conversion from laparoscopic to open was only 4.2%. Some 56% paediatric patients had open appendectomy & 44% laparoscopic with no conversions. Trainees were the sole or first operators in 63% of cases. NAR was just 5.7%. Some 21(10.9%) patients were readmitted within 30 days of which 8 had a collection; all were treated conservatively. Conclusions Accurate clinical diagnosis & selective use of imaging in a dedicated EGS unit optimizes outcomes for appendectomy with low NAR & low complication rates. Appendectomy is effectively undertaken by trainees. LA is safely performed in children.
