What causes intraperitoneal air?
It is most commonly caused by rupture of a hollow viscus such as gastric or duodenal ulcer perforation. Other common causes include feeding tube insertion, bowel anastomotic leak, barotrauma, and intra-abdominal surgery. After a laparotomy, air is usually present for 3–7 days and should not increase in volume.
What does free intraperitoneal air mean?
Free gas, or pneumoperitoneum, is gas or air trapped within the peritoneal cavity, but outside the lumen of the bowel. Pneumoperitoneum can be due to bowel perforation, or due to insufflation of gas (CO2 or air) during laparoscopy.

What is the treatment for free air in the abdomen?
Diagnosis is usually made by the presence of free air in the abdomen on imaging studies. Treatment is with fluid resuscitation, antibiotics, and surgery. Mortality is high, varying with the underlying disorder and the patient’s general health.
What are the symptoms of free air in the abdomen?
Pneumoperitoneum that resulted from a perforation in the abdominal viscera usually manifests with symptoms depending on the subsequent development of the condition. Abdominal pain and abdominal tenderness are common symptoms that are caused by buildup of air or free gas in the peritoneal cavity.
What does free air in abdomen mean?
Perforation of duodenal ulcer: It is one of the most common causes for free air in abdominal cavity. Duodenum is a hollow organ; it is the first part of the small intestine. In general, perforation of any part of the intestine and stomach can precipitate free gas in abdominal cavity.
