    Abstract:
    INTRODUCTION: This study reviews and validates the practice of selective non-operative management (SNOM) of penetrating neck injury (PNI) in a South African trauma service and reviews the impact new imaging modalities have had on the management of this injury. METHODOLOGY: This study was performed within the Pietermaritzburg Metropolitan Trauma Service, in the city of Pietermaritzburg, Kwazulu-Natal, South Africa. A prospectively maintained trauma registry was retrospectively interrogated. All patients with PNI treated over a 46-month period were included within the study. RESULTS: A total of 510 patients were included in the study. There were 452 stab wounds (SW) and 58 gunshot wounds (GSW). A total of 202 (40%) patients sustained isolated PNI, the remaining 308 (60%) patients sustained trauma to at least one additional anatomical region. An airway injury was identified in 29 (6%) patients; a pharyngo-oesophageal injury in 41 (8%) patients and a vascular injury in 86 (17%) patients. Associated injuries included three penetrating cardiac injuries (PCI) and 146 patients with haemo-pneumothoraces. Of the total cohort, 387 patients (76%) underwent CT Angiography (CTA), of which 70 (18%) demonstrated a vascular injury. Formal catheter directed angiogram (CDA) was performed on 16 patients with positive CTA but confirmed injury in only half of these patients. Of 212 patients (42%) who underwent water-soluble contrast swallow (WS-swallow), an injury was demonstrated in 29 (14%) cases. A total of 401 (79%) patients were successfully managed conservatively for PNI and 109 (21%) surgically or by endovascular intervention. Only five (1.2%) patients failed a trial of SNOM and required surgery. The in-hospital mortality rate was 2%. No deaths could be attributed to a failure of SNOM. CONCLUSION: SNOM of PNI is a safe and appropriate management strategy. The conservative management of isolated pharyngeal injuries is well supported by our findings but the role of conservative treatment of oesophageal injuries needs to be further defined. The SNOM of small non-destructive upper airway injuries seems to be a safe strategy, while destructive airway injuries require formal repair. Imaging merely for proximity, is associated with a low yield. CTA has a significant false positive rate and good clinical assessment remains the cornerstone of management.
