| description | Background: Penetrating abdominal trauma (PAT) in South Africa represents a significant burden of disease. The current global trend has seen management shift towards selective conservatism. The purpose of this study is to describe the presentation, management and outcomes of PAT in a level I trauma unit, which routinely practices selective non-operative management (SNOM). Methods: This was a retrospective descriptive audit of prospectively collected data. The Setting was Groote Schuur Hospital Trauma Centre, Cape Town, South Africa over 24 months (1 May 2015 to 30 April 2017). All patients presenting to the centre with PAT during the study period were included. The data captured and analysed included: basic demographics; admission vital signs; blood investigations; number of traumatic insults; penetrating wound positions; radiological investigations and interventions; indication for laparotomy; operative or nonoperative management; laparotomy findings: negative, therapeutic or non-therapeutic; abdominal visceral injuries and associated injuries. The Revised Trauma Score (RTS); Injury Severity Score (ISS); Penetrating Abdominal Trauma Index (PATI); and Kampala Trauma Score (KTS) were then calculated. The descriptive end points included the following: Length of hospital stay (LOS); ICU admission time; relaparotomy; readmission; mortality; and in-hospital complications. Results: During the study period, 805 patients with penetrating abdominal trauma were managed. There were 502 (62.4%) and 303 (37.6%) patients with gunshot and stab wounds, respectively. The majority were young men (762 – 94.7%) with a mean age of 28.3 (95%CI: 27.7-28.9) years. The median trauma scores were as follows: RTS – 7.84 (IQR: 7.00-7.84); ISS: 13 (IQR: 9-22), PATI: 6 (IQR: 1-14); and KTS: 14 (IQR: 14-15). Abdominal penetration was thoracoabdominal in 332 (41.2%), abdominal in 694 (86.5%), and pelvic in 192 (23.9%) patients. Immediate laparotomy was performed in 446 (55.4%) patients for: haemodynamic instability – 42 (5.2%); peritonism – 296 (36.8%); evisceration - 27 (3.4%); unreliable clinical evaluation – 24 (3.0%); and positive radiological findings – 57 (7.1%). There were 406 (50.4%) therapeutic laparotomies; 18 (2.3%) negative laparotomies; and 22 (2.7%) nontherapeutic laparotomies in the immediately operated group. Initial SNOM was performed in 359 (44.5%) patients, of which 208 (68.7%) sustained stab wounds and 151 (30.1%) gunshot wounds. Thirty-five (4.3%) patients failed SNOM and underwent delayed laparotomy. Should a policy of mandatory laparotomy have been implemented in this series, 206 (68.0%) SW and 163 (32.5%) GSW patients would have underwent unnecessary exploration. Overall non-fatal complications were 179 (22.2%) which were then further classified according to the Clavien-Dindo grading system. The median hospital stay was 4.5 (IQR: 3-7) and 7 (IQR: 5-12) days for SW and GSW, respectively. Overall 114 (14.2%) patients required admission to critical care unit for a median stay of 3 (IQR: 2-5) days. Total mortality was 7.2% (n=58). Conclusion: Clinical evaluation (haemodynamic instability, peritonism and evisceration) was remarkably accurate in determining the need for early laparotomy. The unnecessary laparotomy rate of this group was 5.0% (negative: 2.3% and nontherapeutic: 2.7%) overall. Selective nonoperative management was performed in 44.5% of patients with a successful SNOM rate of 90.3%. The overall mortality was 7.2 %. |
