Gallbladder rupture, an isolated seat belt injury.
This report  describes a patient who suffered free intraperitoneal perforation of a previously normal gallbladder as an isolated abdominal injury from seat belt compression. It is postulated that a  prerequisite for such an injury is distension of the gallbladder with bile. Alcohol ingestion in the fasting state is likely to produce  such a situation.
