On the fifth postoperative day after pulmonary lobectomy, a 64-year-old man accidentally connected his nasal catheter (providing six liters of oxygen per minute) to his nasogastric tube. Tension pneumoperitoneum occurred with acute respiratory distress. ⋯ Our case illustrates another unusual cause of tension pneumoperitoneum. Emergency percutaneous decompression was effected with needle aspiration, followed by laparotomy for gastric repair covered by an omental flap.
