Patterns of retroperitoneal trauma following gunshot violence: A case series()

INTRODUCTION: Abdominal trauma is defined as any injury to the abdomen and its containing viscera. Common penetrating injuries including gunshot or stab injuries are increasing worldwide. However, retroperitoneal gunshot injuries have a lower incidence than trans-abdominal trauma and can have substantially different outcomes. CASE REPORT: We report a series of three family members involved in gunshot violence over an18-month period. Each sustained retroperitoneal gunshot injuries with varying injuries patterns and treatment courses. Interestingly, one patient had a delayed small bowel perforation on day 6 post injury. DISCUSSION: Retroperitoneal trauma following gun violence has a lower incidence than trans-abdominal trauma. There is a paucity of literature describing injury patterns following this type of injury and their subsequent management. In the context of penetrating retroperitoneal trauma, the retroperitoneal organs are at risk and therefore serial clinical and/or radiological assessment is necessary. Delayed small bowel injury as a consequence of retroperitoneal gunshot is an unusual finding, with no reports to our knowledge in the literature. CONCLUSION: this case series highlight that penetrating retroperitoneal trauma can produce a variety of injury patterns. Therefore a wide clinical acumen is needed to ensure a successful outcome. The trajectory of the bullet may help ascertain potential injuries, but serial assessment and observation are also important. Ultimately, individual cases must be treated accordingly, based on clinical stability, severity of injury and radiological findings. Despite initial stability, patients should always be observed for delayed complications.
