Previous experience in Cambridge in the management of liver trauma has led to the evolution of a protocol for surgical intervention to secure control of haemorrhage from the injured liver. We report 80 cases of liver trauma including 12 who were initially managed non-operatively; three of these subsequently required operation. Of the 80, all but five suffered blunt abdominal trauma. Perihepatic packing was used to manage 29 patients, of whom 21 were initially treated elsewhere before being transferred to Cambridge. Six of these required a hemihepatectomy at subsequent exploration. Of the 39 patients who underwent urgent laparotomy and definitive surgery, 11 (28 per cent) died; only three out of 29 (10 per cent) died after initial packing. Only one death from hepatic complications occurred after packing and subsequent transfer.
