Tension pneumoperitoneum after heart-lung transplantation.

Tension pneumoperitoneum is a medical emergency. We report 2 cases in which tension pneumoperitoneum occurred after heart-lung transplantation and was related to positive-pressure ventilation and a transdiaphragmatic passage of omentum used to wrap the airway anastomosis. Management in these patients was targeted toward decompression of intraperitoneal air with percutaneous needle or tube placement without exploratory laparotomy, and tube thoracostomy for the concomitant pneumothorax.
