Selective non-operative management of abdominal gunshot wounds: survey of practise

Abstract

Background: There is a growing body of evidence attesting to the effectiveness and safety of selective non-operative management (SNOM) of abdominal gunshot wounds. However, much of the research which supports this conclusion has originated from a few centres, and the actual utilisation of SNOM by trauma surgeons is not known. We therefore conducted a survey to assess the acceptance of this strategy and evaluate variations in practise.

Methods: Electronic questionnaire survey of trauma surgeons in the United States of America, Canada, Brazil, and South Africa. Responses were compared using Chi(2) and Fisher's exact tests.

Results: 183 replies were received. 105 (57%) respondents practise SNOM of abdominal gunshot wounds, but there are marked regional variations in the acceptance of this strategy (p<0.01). Respondents who had completed trauma (p<0.01) or critical care (p<0.01) fellowships, and those who practise in a higher volume centre (defined as >50 penetrating abdominal injuries seen per year) (p<0.01) are more likely to practise SNOM of gunshot wounds. Most surgeons who practise SNOM regard peritonitis, omental and bowel evisceration, and being unable to evaluate a patient as a contraindication to attempting non-operative management. Almost all regard CT as essential. Respondents' preparedness to consider SNOM is related to injury extent.

Conclusions: SNOM of abdominal gunshot wounds is practised by trauma surgeons in all four countries surveyed, but is not universally accepted, and there are variations in how it is practised.
