Intrahepatic hematoma with secondary Salmonella infection via biliary fistula.

Usually liver hematoma after blunt trauma is treated conservatively as long as clinically possible, in order to avoid infection via drainage. We report a patient who developed a huge liver abscess after a minor blunt trauma caused by a piece of wood that hit his hepatic region during work with a circular saw. Neither conservative treatment nor percutaneous drainage was successful and intraoperatively a biliary fistula was identified as the route of infection by salmonella. Cholecystectomy (here meaning removal of the salmonella reservoir) and consequent drainage of the gall flow via T-drain were the crucial therapeutic steps and the fistula finally closed after three months. Therapeutic possibilities in the management of blunt liver trauma, and biliary and septic complications are discussed.
