Pneumoperitoneum

Summary of Pneumoperitoneum
Pneumoperitoneum is the abnormal presence of air or other gas in the peritoneal cavity. The most common cause is a perforated abdominal viscus, generally a perforated peptic ulcer, although any part of the bowel may perforate from a benign ulcer, tumor or abdominal trauma. A perforated appendix seldom causes a pneumoperitoneum.
