Spontaneous pneumoperitoneum without peritonitis is a rare phenomenon which poses a dilemma to the surgeon faced with this problem. Two such cases and their outcome are presented. The first case was caused by barotrauma during positive pressure ventilation and was treated by laparotomy. ⋯ A compilation of other etiologies 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 perforation of a viscus, we advise performing an abdominal tap. If negative, continued observation is advised.

Records of 345 patients in whom laparatomies were performed because of blunt and penetrating abdominal trauma were reviewed retrospectively with respect to factors affecting mortality. One hundred and twenty-eight patients had blunt abdominal trauma (Group I), 114 patients had gunshot wounds of the abdomen (Group II), and 103 patients had stab wounds of the abdomen (Group III). ⋯ The presence of head trauma especially if accompanied by hypotension in group I, and the presence of chest trauma (hemothorax and/or pneumothorax) and hypotension (less than 90 mmHg) in group II were associated with a high mortality rate (p less than 0.05). Of the two patients who died in group III, one had septic shock due to massive intestinal necrosis and the other had hemorrhagic shock due to multiple organ injury and bleeding from an injured internal thoracic artery as the cause of death.
