A method for detecting a bowel perforation injury, said method comprising:
- obtaining an aspirate sample from a abdominal or pelvic cavity of a patient;
- filtering said aspirate sample to separate a gas component of the sample;
- analyzing said gas component using a gas-detecting means to determine the concentration of gases in the sample;
- wherein an elevated level of a gas normally present in the bowel and not normally present in the abdominal or pelvic cavity indicates the presence of a bowel perforation injury.
