Extended Focused Assessment Sonography in Penetrating Abdominal Trauma (EFAST) has emerged as a valuable tool in the initial evaluation of patients with abdominal injuries. This diagnostic modality encompasses a systematic ultrasound examination aimed at detecting free fluid, organ injury, and other signs indicative of intra-abdominal pathology following penetrating trauma. The accuracy of EFAST in identifying these injuries is of paramount importance, as timely and accurate diagnosis can significantly impact patient management and outcomes. Therefore, understanding the diagnostic accuracy of EFAST in penetrating abdominal trauma is essential for clinicians to make informed decisions regarding patient care. In this introduction, we will explore the current evidence surrounding the diagnostic accuracy of EFAST, including its sensitivity, specificity, and overall reliability in detecting intra-abdominal injuries resulting from penetrating trauma. By elucidating the strengths and limitations of EFAST in this context, we aim to provide insights that can inform clinical practice and contribute to the optimal management of patients with penetrating abdominal trauma.
