Abstract
Gas in the tissues following perforation of the bowel may be due to either a direct escape of gas from the perforated bowel or to infection with gas-producing organisms released from the damaged gut. The direct escape of gas from the ruptured bowel will in the case of the pelvic colon result in a pneumoperitoneum, or in the case of the rectum either a pneumoperitoneum or a localised collection of gas in the pararectal tissues, depending on the site of rupture. These appearances have been recently reviewed by Slater (1957). The gas resulting from infection by gas producing organisms will in the first instance be formed in an abscess related to the damaged area, but this abscess may track to more distant points with the resulting spread of the gas translucencies.
