title: Pneumoperitoneum following tension pneumothorax. Report of two cases.
abstract: Two cases of pneumoperitoneum following tension pneumothorax are described. Lungs in both patients had identifiable pathology and were ventilated with high inflation pressure and moderate positive end-expired pressure (PEEP). Laparotomy was performed in both patients with no evidence of intra-abdominal viscus perforations. A possible mechanism for the production of pneumoperitoneum is discussed.
