A 28-year-old man presents to the emergency department 2 hours after sustaining a stab wound to the left anterior chest wall at the 5th intercostal space, mid-clavicular line. He is haemodynamically stable with a blood pressure of 128/82 mmHg, heart rate 92/min, and respiratory rate 18/min. Breath sounds are equal bilaterally. There is a small amount of blood oozing from the wound. On examination, the wound tract cannot be fully visualized due to depth. What is the most appropriate next step in management?
