Usually, pneumoperitoneum is due to perforation of a hollow abdominal organ. In the absence of peritoneal symptoms, pneumoperitoneum may be due to other causes. Two patients with pneumoperitoneum without perforation were treated in our department. ⋯ The treatment was conservative. Both patients left the hospital in good health. More knowledge of the less frequent causes of pneumoperitoneun without perforation can possibly contribute to to refraining from exploratory laparotomy in these cases.
