Resuscitative thoracotomy (RT) is a last-resort intervention for traumatic cardiac arrest or impending cardiovascular collapse. Although outcomes after RT are well described in civilian trauma, data from modern warfare-characterized by high-energy penetrating mechanisms, advanced prehospital care, and rapid evacuation-remain limited. This study evaluated the characteristics and outcomes of RT performed during recent combat operations within a combined military-civilian trauma system. We conducted a retrospective cohort study of all combat casualties who underwent emergency department (ED) RT during the Israel-Hamas conflict (October 27, 2023, to October 27, 2025). Data were extracted from prehospital and ED medical records and postmortem computed tomography reports. RT was defined as a thoracotomy performed in the ED in a pulseless patient with the intent to restore spontaneous circulation. The primary outcome was 30-day survival. Secondary outcomes included return of spontaneous circulation (ROSC) and 24-hour survival. Among 2,335 combat trauma admissions, 27 patients (1.2%) underwent RT. All were young male casualties with penetrating injuries, predominantly from explosive mechanisms (74.1%). Severe trauma was common (ISS ≥25 in 92.6%). Prehospital blood products were administered in 77.8% of patients, and 66.7% arrived at the ED within 60 minutes of injury. ROSC was achieved in 40.7%, of whom 90.9% were transferred to the operating room. Two patients (7.4%) survived to 24 hours and 30 days, both with good neurologic outcomes. No patient who lost pulse before hospital arrival survived. Among modern warfare casualties treated at civilian trauma centers, survival after RT is comparable to that reported in civilian series, despite severe and complex injury patterns. RT should not be considered futile for penetrating abdominal, pelvic, or extremity hemorrhage, even in the presence of associated head injury. In contrast, prehospital circulatory arrest is associated with an extremely poor prognosis.(J Trauma Acute Care Surg. 2026;000:000-000. Copyright © 2026 Wolters Kluwer Health, Inc.
