Trends in the Management of Abdominal Gunshot Wounds Over the Last Decade: A South African Experience.

Background: This study aimed to review our decade-long experience with the management of abdominal gunshot wounds (GSWs), to document trends in our approach and to develop an evidence base for our contemporary management algorithms in a major trauma in South Africa.

Materials And Methods: This was a retrospective study that included all adult patients with abdominal GSWs between January 2013 and October 2020 managed at a major trauma centre in South Africa.

Result: Five hundred and ninety-six cases were included (87% male, mean age: 32 years). The median Injury Severity Score (ISS) was 12. 52% (309/596) of cases had indications of immediate laparotomy and proceeded directly to the operating room without any CT imaging. Of this cohort, the laparotomy was positive in 292 and in the remainder (5%) was negative. Of the remaining 287 cases, 209 underwent a CT scan (35%). 78 were managed without any CT imaging. Of the 78 who did not undergo CT scan, all were managed without any operation and discharged home well. Of the 209 who underwent CT scan, 99 were observed and only one case in this group subsequently required a laparotomy. The remaining 110 cases underwent a laparotomy, which was negative in 7. There were correlations with increasing use of CT, as well as a decrease in those proceeding directly to laparotomy. The overall morbidity rate was 8% (47/596). 32% (190/596) require intensive care unit (ICU) admission. The overall mortality rate was 8% (67/596).

Conclusions: The management of abdominal GSWs has continued to evolve. There is now a well-defined role for selective non-operative management in this group of patients and relies on accurate CT assessment. CT scan is now an important component in the management of abdominal GSW even in our resource-constrained environment.
