Aim: Japan has a low crime rate, but a high suicide rate. The aim of this study is to review the causes of penetrating traumatic injuries in a tertiary care emergency center in Japan.
Methods: We retrospectively reviewed all admissions for traumatic injuries over a 3-year period, and calculated the proportion of patients with penetrating traumatic injuries. Weapon used, age, gender, Injury Severity Score, cause of injury, and site of injury in all patients with Penetrating injuries were reviewed. The proportion of patients with Penetrating injuries among patients with all types of traumatic injuries requiring surgical intervention was calculated.
Results: Of 1,321 patients admitted over 3 years, 65 patients (5%) suffered from Penetrating injuries. Most were stab wounds, with only one gunshot (2%). The most common site of injury was an extremity (48%). The most common cause of penetrating injury was self-inflicted (38%). The abdomen is the most common site injured among self-inflicted injuries. Of patients with all types of traumatic injuries requiring surgical intervention, Penetrating injuries accounted for 23%.
Conclusion: Penetrating injuries represent 23% of all patients with traumatic injuries who required surgical intervention. Self-inflicted Penetrating injuries were most common, supporting the need for preventive services. Acute care surgeons must be familiar with the surgical management of penetrating traumatic injuries, even in a country with a low crime rate.
