Background: Global trend has seen management shift towards selective conservatism in penetrating abdominal trauma (PAT). The purpose of this study is to compare the presentation; management; and outcomes of patients with PAT managed operatively versus non-operatively. Methods: Prospective cohort study of all patients Ùpresenting with PAT to Groote Schuur Hospital, Cape Town from 01 May 2015 to 30 April 2017. Presentation; management; and outcomes of patients were compared. Univariate predictors of delayed operative management (DOM) were explored. Results: Over the 2-year study period, 805 patients with PAT were managed. There were 502 (62.4%); and 303 (37.6%) patients with gunshot (GSW) and stab wounds (SW), respectively. The majority were young men (94.7%), with a mean age of 28.3 years (95% CI 27.7–28.9) and median ISS of 13 (IQR 9–22). Successful non-operative management was achieved in 304 (37.7%) patients, and 501 (62.5%) were managed operatively. Of the operative cases, 477 (59.3%) underwent immediate laparotomy and 24 (3.0%) DOM. On univariate analysis, number; location; and mechanism of injuries were not associated with DOM. Rates of therapeutic laparotomy were achieved in 90.3% in the immediate, and 80.3% in the DOM cohorts. The mortality rate was 1.3, 11.3 and 0% in the in the NOM, immediate laparotomy and DOM subgroups, respectively. The rate of complications was no different in the immediate and DOM cohorts (p > 0.05). Conclusion: Patients with PAT in the absence of haemodynamic instability; peritonism; organ evisceration; positive radiological findings, or an unreliable clinical examination, can be managed expectantly without increased morbidity or mortality.
