Broad subcutaneous emphysema with airway obstruction during robot‐assisted partial nephrectomy: A case report and literature review

Introduction Subcutaneous emphysema is a relatively common complication in laparoscopic surgery. However, airway obstruction secondary to subcutaneous emphysema is rare. Case presentation A 63‐year‐old woman with a 56‐mm left renal tumor underwent a robot‐assisted partial nephrectomy. The operative time was 155 min, the insufflation time was 108 min, and the estimated blood loss was 70 mL. The pneumoperitoneum pressure was maintained at 12 mmHg, except at 15 mmHg for 19 min during tumor resection. The end‐tidal CO2 was
