Primary Outcome Measures:
  • Length of stay [ Time Frame: Measurement made on day of discharge which is expected to be on average bewteen 5 and 10 days after surgery. ]
    Number of days (to nearest half day) patients stay in hospital.

Secondary Outcome Measures:
  • Pain Scores [ Time Frame: Performed daily at 0900 hours. On the day of surgery pain scores will be performed at 2, 6 and 12 hours post surgery. ]
    Visual analogue scores of pain experienced.

  • Molecular response to surgery [ Time Frame: Days 0, 1 and 3 ]
    HMGB1, RAGE and cytokines

  • Central Venous Pressure [ Time Frame: During liver transection ]
    Mean Central Venous Pressure during liver transection will be quantified and compared between groups.

  • Estimated Blood Loss [ Time Frame: Intra-operative ]
  • Operative field asessment [ Time Frame: During liver transection ]
  • Pringle time [ Time Frame: Intra-operative ]

Other Outcome Measures:
  • Quality of Life (EQ-5D) [ Time Frame: Pre-operative, 2 weeks post-operative, 4-6 weeks post-operative ]
  • Morphine consumption [ Time Frame: Day of surgery and postoperative days 1-7 ]
  • IV Fluid volume [ Time Frame: Day of Surgery and postoperative days 1-7 ]
  • Complications [ Time Frame: day of surgery and post-operative days 1-30 ]
  • Post-operative blood tests (FBC, U&E, LFTs, coag) [ Time Frame: Post-operative days 1-7 ]
