Severe subcutaneous emphysema caused by small injury to the abdominal wall during robot-assisted laparoscopic radical prostatectomy

A 67-year-old man underwent RARP in the Trendelenburg position with pneumoperitoneum at 12 mmHg. Gradual elevation of End-tidal CO2(EtCO2) began, and extensive subcutaneous emphysema was recognized when EtCO2 reached 58 mmHg. After interruption of pneumoperitoneum, careful observation of the surgical field led to detect an injury of the abdominal wall of 1 cm in length, suggesting the cause of severe subcutaneous emphysema. The injury was repaired and RARP was terminated without any cardiovascular problems. Attention should be paid that even minor abdominal wall injury could lead to severe subcutaneous emphysema which may cause respiratory or cardiovascular problems during laparoscopic surgeries.
