Two cases of spontaneous pneumoperitoneum without peritonitis.
Spontaneous pneumoperitoneum without peritonitis is a rare phenomenon which poses a dilemma to the surgeons faced with this problem. Two such cases and their outcome are presented. The first case was caused by tracheal rupture during emergency intubation and was treated by observation until complete resolution. The second case was caused by barotrauma during positive pressure ventilation and was treated by laparotomy. Both patients died for reasons unrelated to the pneumoperitoneum. The passage of air from the chest cavity into the abdominal cavity was along the great vessels in the first case and through the diaphragm in the second. A compilation of other aetiologies of pneumoperitoneum without peritonitis as extracted from the literature is presented. In the presence of pneumoperitoneum without peritonitis and when the clinical history does not suggest visceral perforation, an abdominal tap or lavage should be attempted. If negative, continued observation is advised.
