Perforation of the jejunum from blunt abdominal trauma.

Thirteen cases of jejunal perforation from blunt trauma are presented. There are no reliable signs or symptoms, and a normal physical examination may be seen. Free intraperitoneal air on plain radiograms is characteristically absent. Simple debridement and closure is adequate. Mortality is usually associated with other serious concomitant injuries, and complications are associated with diagnostic delays. Diagnostic peritoneal lavage is a safe and reliable procedure for establishing an early diagnosis of serious intraperitoneal injury. Its routine use in all cases of serious blunt abdominal trauma is advocated.
